Building a small house (up to 80 m²) seems like a simpler alternative for those who want to quickly set up their own home without major bureaucratic obstacles. However, even this type of construction is subject to clear legal requirements, and failure to comply with them can have serious legal consequences, ranging from mandatory suspension of construction to a requirement to demolish the building. In this article, we explain in detail what is currently required by law, when a building permit is required and when it is not, and what documents are needed if a permit is required.

What is considered a simple structure under the law

According to the currently valid Regulation on the Classification of Structures STR 1.01.03:2017 (as amended on October 24, 2024), buildings up to 80 m² can be classified as simple structures. Such structures can usually be built under a simpler procedure, but only if they meet specific technical parameters.

A simple structure is not defined solely by its area – other criteria must also be taken into account, which we will look at below.

1. Area limit – 80 m²

According to Annex 5 (STR 1.01.03:2017), Group I simple residential buildings are subject to the condition that the total area of the building must not exceed 80 m² and the height of the building must not exceed 5 m. This means that both the total area and the height must be assessed together – if either of these indicators is exceeded, the building loses its uncomplicated status.

Note: the total area includes not only living rooms, but also all appurtenances of the building – vestibules, storage rooms, attics (if they are used as living space), etc.

2. Height and number of floors

A simple structure may not be higher than 5 meters from the ground, measured from the lowest point of the surface. The building must also be single-story—even if an attic is built, it should not be treated as a full second floor.

According to the law, if a second floor is built or the height exceeds 5 meters, the building becomes more complex and is subject to stricter design and permit requirements.

3. Building group – I or II?

According to the regulations, buildings up to 80 m² can be classified as either group I or II. The difference between them depends on:

• the intended use of the building (residential, non-residential, auxiliary, etc.);
• whether the building is located in an urbanized area;
• whether the building is classified as hazardous due to the materials or technologies used.

Generally, single-family residential buildings that meet the specified parameters and are not used for hazardous activities are considered simple buildings in group I.

“A simple structure must not only be small, but also safe, both in terms of its construction and its impact on the environment. Legal liability depends on this,” says Romas

Mikulėnas, VTPSI engineer.

When is a building permit not required for a house up to 80 m²?

When considering a small detached house, many builders hope to avoid a lengthy permit approval process. And indeed, in some cases, a building permit is not required for a house up to 80 m², but only if all the specific conditions set out in the applicable legislation and the recommendations of the Ministry of the Environment and the VTPSI are met.

In addition to meeting these conditions, any structure, regardless of its size, must be built legally, otherwise it would be considered unauthorized construction.

No permit is required if the following conditions are met

According to the explanations of the VTPSI for 2023–2024, a building permit is not required if the following is being built:

• a single-family residential building with a total area of up to 80 m²;
• no higher than 5 m;
• in an unurbanized area where no detailed plan has been approved;
• not in a cultural heritage area;
• not on state-owned land (unless you have a trust or lease right);
• without connection to centralized engineering networks (water supply, sewerage, heating networks).

In this case, a permit is not mandatory, but the building must still be legally registered, and after completion of construction, a declaration of completion of construction must be submitted.

“Not everything that is small is simple. Failure to comply with requirements can cost thousands – not in documents, but in court.” – Tomas Bacevičius, construction lawyer.

When is a permit mandatory?

There are many cases where a building permit is required even for a small house, for example:

• if it is being built in an urbanized area with an approved detailed plan;
• if the building is connected to utilities (sewer, water, heating);
• if it is being built in a protected area, including cultural heritage sites or regional parks;
• if the planned construction exceeds the established technical parameters – height, area, or purpose.

In such cases, it is necessary not only to obtain a permit, but also to prepare a technical work project, which must be coordinated with the responsible authorities.

Where and how can such a house be built?

When building a detached house of up to 80 m², it is important to know that even simple structures are subject to strict territorial, purpose, and legal restrictions. Construction possibilities depend not only on the size of the building, but also on the location where it is planned – the purpose of the plot, its location, and special territorial restrictions.

The purpose of the plot is the main limiting factor

A residential house may only be built on a plot of land whose main purpose allows it. If the plot is intended for agricultural use, it is necessary to check whether part of the plot has already been rezoned for another purpose (e.g., single-family residential area) before starting construction. Otherwise, a change of purpose procedure will have to be carried out, and failure to do so will result in illegal construction.

Urbanized or non-urbanized area

A very important factor is whether the plot is located in an urbanized or non-urbanized area. In non-urbanized areas where there is no approved detailed plan, construction may be simpler and sometimes even does not require a permit. Meanwhile, in urbanized areas, especially those with approved planning documents, a permit is almost always required, even for buildings smaller than 80 m².

Protected areas and heritage

Before starting construction, it is necessary to find out whether the planned object is located in a protected area – regional parks, nature reserves, or cultural heritage protection zones. In such areas, construction is only permitted with additional approvals and often subject to stricter architectural and environmental requirements. All approvals must be obtained from the responsible authorities – the Department of Cultural Heritage, the National Service for Protected Areas or the local municipality.

Distances from plot boundaries and neighboring buildings

Even without a permit, a building must comply with technical standards, especially regarding distances from plot boundaries. The minimum distances depend on the type of construction, the purpose of the building, and other criteria, but they must be observed in all cases. Failure to comply with the specified distances may not only result in complaints from neighbors, but also in the obligation to rebuild or even demolish the structure.

“The most common mistake is to think that if no permit is required, then nothing needs to be checked. But even without a permit, you must comply with the regulations for the use of the territory,” says Dainius Kamaitis, chief architect of the municipality.

Other technical and design requirements

Even if a building permit is not required for this type of building, this does not mean that there are no technical or design requirements. Even when building a small, simple house, it is necessary to follow certain procedures, failure to comply with which can have serious consequences. In this section, we will review the most important aspects that a builder must pay attention to before starting work.

Is a design necessary?

According to the Construction Law, if a single-family residential building of up to 80 m² is being built, a design may not be necessary if no building permit is required and if the building is not being built in an urbanized area.

However, even in such cases, the VTPSI recommends preparing at least a minimal technical drawing that clearly indicates the location of the building on the plot, the building area, height, distances from the plot boundaries, and other basic technical data.

This document is particularly important when declaring the completion of construction and registering the building with the Register Center.

When is a building inspection or engineer required?

If a more complex structure is being built, unusual materials are being used, the building is located on a slope, in a flood zone, or there is a risk due to ground conditions, the builder must consult a qualified engineer or architect. Such a specialist will not only help to assess the reliability of the structures, but will also ensure that the project complies with the requirements of the STR and is legal.

An expert assessment is mandatory when:

• a building permit is required (e.g., in an urbanized area),
• the building is designed with underground parts,
• unusual or large span structures are planned.

Declaration of completion of construction

Regardless of whether a permit was required or not, after completion of construction, a declaration of completion of construction must be submitted, which is the most important document for registering the structure and proving that the construction was carried out legally. The declaration specifies the main details of the building, the builder’s responsibility, and other necessary documents (e.g., topographical photograph, cadastral measurements) are attached.

Without this step, the Register Center will not register the building, which means that it cannot be sold, mortgaged, or used as a place of residence later on.

How to prepare for construction – practical steps

Although construction of up to 80 m² may seem like a simpler process, in reality, success depends on proper preparation. Even if no permit is required, it is necessary to consider all aspects, from legal analysis of the plot to the organization of the construction process. In this section, we will review the most important practical steps that every responsible builder must take.

Legal analysis and document verification

The first step is to assess the legal situation of the plot. You need to check the intended use of the plot and whether there are any registered easements, restrictions, or planning documents. This can be done through extracts from the Register Center and the local government or municipality that administers the territory.

If there are any doubts about the possibility of construction, it is worth consulting a land-use planning specialist or a construction lawyer.

Design: to hire an architect or not?

If a permit is not required, the design may not be formally mandatory. However, in practice, it will be difficult without drawings to:

• plan the exact location of the building;
• complete the construction completion procedures;
• register the building.

Therefore, even for a simple building, it is recommended to order at least a minimal technical design or use standard designs if a modular or frame house is being built.

“Drawings are not bureaucracy, but a means of control. Without them, you won’t even know what your contractor is building,” says Laurynas Staniulis, head of a design company.

Cost planning and selection of contractors

Before starting construction, it is necessary to estimate the costs. Even a small house can require significant expenses if the wrong technologies, materials, or work processes are chosen.

It is important to decide whether all the work will be done by the builder themselves or whether a contractor will be hired. If you choose to build yourself, keep in mind that you will be responsible for complying with all legal requirements, submitting declarations, and ensuring that the building meets all requirements.

If a contractor is hired, it is necessary to draw up a written contract that clearly defines the scope of work, duration, and guarantees.

Most common practical mistakes

The construction process is sensitive not only to legal but also to practical issues. Among the most common mistakes are failure to assess soil conditions, inaccurate measurement of distances to the plot boundaries, construction without at least a minimum project, and failure to submit a completion declaration.

All these mistakes can be avoided if the process is planned responsibly, rather than “by eye.”

Before starting the construction, reconstruction, or demolition of any special or non-special structure, the builder must submit an official notification of the start of construction. This procedure is mandatory and regulated by Technical Regulation for Construction STR 1.05.01:2017, paragraph 39.

This is not a formality – failure to notify the start of construction in a timely manner may result in even legally obtained building permits being considered invalid in practice, and the construction itself being considered illegal.

When should the notification be submitted?

According to the regulations in force, a builder carrying out the following works:

• construction of a new building,
• reconstruction or demolition of a building,
• renovation (modernization) of a building,

must submit the following information no later than 1 working day before the start of construction:

• the date of commencement of construction,
• the contractor hired or appointed,
• the construction project supervisor,
• the construction manager,
• the technical supervisor of the construction.

This applies to both natural and legal persons.

These requirements are set out in point 39 of the Technical Regulations for Construction STR 1.05.01:2017, approved by Order No. D1-871 of the Minister of the Environment of the Republic of Lithuania on December 12, 2016.

How is the notification submitted?

Information about the start of construction is submitted via the IS Infostatyba information system, whose main public address is www.planuojustatau.lt.

• The notification is completed by one of the builders, if there are several, but it must be signed by all builders or their authorized representative with a qualified electronic signature.

It is important that the data is submitted before the start of construction – this means that if the notification is not submitted on time, the works cannot be started legally.

What to do if the contractor or managers change?

If the following change during construction:

• contractor,
• construction manager,
• project implementation supervisor,
• technical supervisor,

builder within 3 working days of their appointment or assignment, they must submit updated information via the IS “Infostatyba.”

If this information is submitted late or not at all, the Inspectorate may impose administrative penalties and, if necessary, temporarily suspend the work.

How long does it take to complete the notification?

The service itself is:

• free of charge,
• the information provided is registered within 1 working day in Infostatyba,
• if submitted in writing, the information is published in the system no later than the next working day.

The time required to enter the data depends on the information available about the project, but the system itself is designed so that all fields can be filled in quickly.

Where to apply?

The State Territorial Planning and Construction Inspectorate under the Ministry of the Environment provides consultations at the following contacts:

• Phone: +370 5 207 3333
• Email: info@vtpsi.lt
• Website: www.vtpsi.lrv.lt

Summary

Notification of the start of construction is a prerequisite for legally commencing work. It must be submitted no later than one working day before the start of work, and any changes in contractors or managers must be registered within three working days.

Failure to comply with this obligation may result in serious legal consequences, including administrative liability and suspension of construction. Therefore, even for small projects, it is worth ensuring that the data is submitted correctly and that the procedures are followed.

Our independent construction experts will help you ensure that the entire procedure is carried out legally, smoothly, and without the risk of fines or work stoppages.

When planning to build a new residential house or apartment building, one of the most important aspects is the energy efficiency of the building. From January 1, 2021, all newly constructed buildings in Lithuania must comply with the A+ energy efficiency class. This means not only high thermal insulation and energy saving indicators, but also a certain level of engineering systems and technological solutions.

In this article, we will explain exactly what the A+ class means, what its main requirements are, how much it costs, and what you need to know to ensure that your construction project complies with all applicable legislation.

What is the A+ energy efficiency class?

Class A+ is a category of nearly zero-energy buildings regulated by both national and EU legislation. Buildings in this class must be designed to consume as little energy as possible and obtain most of it from renewable sources. The main difference between the A, A+, and A++ classes lies not only in the level of thermal insulation, but also in the efficiency of engineering systems, airtightness, and the integration of renewable resources.

“Class A+ means that a building is not only well insulated, but also interacts with the environment – it passively saves energy and actively produces or uses green energy,” says Andrius Petkevičius, energy certification expert.

What is the difference between A, A+, and A++ classes?

• A class: high thermal resistance, but renewable energy is not required.
• Class A+: stricter requirements for airtightness, energy savings, and at least partial use of renewable energy sources.
• Class A++: the highest level, where energy consumption is almost zero or the building produces more energy than it consumes.

An A+ class building must not only use heat efficiently, but also have appropriately designed systems – from heat recovery ventilation equipment to alternative energy solutions.

When is A+ class mandatory and to which buildings does it apply?

A+ energy efficiency class in Lithuania is not just a recommendation – it is a mandatory requirement for all new buildings, effective from January 1, 2021. This change is part of Lithuania’s commitments to European Union directives aimed at reducing overall energy consumption and greenhouse gas emissions.

When does the requirement come into force?

According to information from the Ministry of the Environment, from 2021, when constructing any new building – whether a detached house, apartment building or public building – it will be mandatory to ensure that it meets the criteria for class A+. This means that the design stage must include solutions that meet the specified levels of thermal insulation, airtightness, and efficiency of engineering systems.

Does this apply only to new buildings?

Yes, the A+ class requirements apply only to new buildings. However, if an existing building is to be renovated or refurbished, depending on the extent of the intervention, it may be required to achieve at least class C or B, and in some cases class A. In each case, the requirements are assessed individually based on the regulations in force at the time the building permit was issued.

Class A+ is the minimum standard for new buildings only. This means that even if a small house with an area of 50 m² is being built, it is still subject to the same energy efficiency criteria as a 200 m² villa.

Basic requirements for class A

In order for a building to be classified as energy efficiency class A+, it is not enough to simply insulate the walls or roof to a high standard. This class has complex requirements that cover the thermal properties of the building envelope, airtightness, the efficiency of engineering systems, and the use of renewable energy. All these indicators must be based on calculations and proven through energy performance certification.

Thermal resistance of building envelopes

All external building envelopes – i.e., walls, roofs, floors, floors, windows, and doors – must meet strict thermal resistance (R) and heat transfer coefficient (U) requirements.

• For walls U ≤ 0.11 W/(m²·K)
• Roof U ≤ 0.09 W/(m²·K)
• Windows and doors U ≤ 0.85 W/(m²·K)

The requirements are based on standards, and failure to comply with them means that the building will not receive an A+ certificate, even if all other parameters are met.

Elimination of thermal bridges

When designing an A+ class building, it is necessary to eliminate thermal bridges – places where heat insulation may be poorer due to materials or structural solutions. These are usually window installation areas, foundation joints, and corners.

All these areas must be addressed so that there are no heat loss points that would increase overall heat consumption and reduce the building’s class.

Air tightness (Blower Door test)

One of the most important A+ criteria is the air tightness of the building. According to legislation, the air permeability coefficient (n₅₀) of an A+ class building must not exceed 0.6 1/h, which is checked by performing a so-called “Blower Door” test – the building is hermetically sealed and the air flow through leaks is measured.

This test is mandatory during certification, and negative results may be grounds for not granting the A+ class. For this reason, attention must be paid to airtightness not only during design but also during construction, especially when installing windows, floors, and sloping roof joints.

Engineering systems

In addition to thermal insulation and airtightness, the A+ class also has requirements for engineering systems. The building must be equipped with energy-efficient heating, ventilation, hot water, and electrical systems.

The seasonal efficiency coefficient (SCOP or SEER) of the equipment used must meet the minimum requirements; it is usually recommended to choose heat pumps or other high-efficiency sources.

“Many people think that thick insulation in the walls is enough. But if you install a cheap, inefficient boiler or windows with poor sealing, the A+ class will remain only theoretical,” says Eimantas Gargasas, construction consultant.

What heating and ventilation solutions are necessary for an A+ class building?

The A+ energy efficiency class requires not only well-insulated walls, but also efficiently operating engineering systems.

One of the most important elements in achieving such energy efficiency is ventilation, heating, and renewable energy solutions, which contribute significantly to the overall energy balance of the building.

Recuperative ventilation system – almost a necessity

According to the recommendations of the Ministry of the Environment and the energy efficiency assessment methodology, a recuperative system is practically inevitable if A+ class is to be achieved.

This system not only ensures fresh air in the rooms, but also recovers up to 80-90% of the heat from the exhaust air, thus reducing the need for heating.

Without mechanical ventilation with heat recovery, it is very difficult to achieve low energy consumption, especially in smaller buildings where natural ventilation causes significant heat loss.

Heating systems: efficiency is more important than type

There is no specific type of heating system required for class A+, but it is essential that it is energy efficient. The most popular solutions are:

• heat pumps (air-water, ground-water);
• gas condensing boilers (in some cases);
• combined solutions with domestic hot water production.

The seasonal performance factor of the systems used must be high enough to meet the total calculated energy demand and achieve the required building class. The higher the efficiency of the system, the lower the residual energy demand that must be covered by renewable sources.

Renewable energy – a mandatory component

According to the current methodology, A+ class buildings must use at least part of their energy from renewable sources. These may include:

• solar power plants (photovoltaic systems),
• solar collectors for hot water production,
• biofuel boilers, or other solutions using renewable resources.

According to the Ministry of the Environment, these sources must cover at least 10-15% of the building’s energy needs from renewable sources in order for the building to be classified as A+.

“Sustainability and efficiency are not goals for the future, but the norm for the present. Every A+ building must integrate advanced systems that work together to save energy.” – Rūta Zableckienė, Senior Specialist at the Construction and Spatial Planning Policy Group of the Ministry of the Environment.

How much do A+ class solutions cost and is it worth investing in them?

One of the most common questions among builders is whether it is really worth striving for an A+ energy efficiency class. Although this will be mandatory for all new buildings from 2021, these requirements have a direct impact on the construction budget. However, on closer inspection, this investment usually pays off not only economically but also legally, due to a simplified commissioning process and higher property values.

How much does construction cost on average?

According to the Ministry of the Environment, the transition from class A to A+ increases the total construction budget by an average of 8–12%. Additional costs arise due to:

• higher thermal insulation requirements (thicker layers, more expensive materials);
• the need for heat recovery ventilation systems;
• high-efficiency heating equipment (e.g., heat pumps);
• the integration of solar power or other renewable energy sources.

These investments are usually divided between building materials and engineering systems. Meanwhile, design and coordination costs do not change significantly, as A+ class design has already become the market standard.

Can a financial return be expected?

Yes, and not only from lower heating costs. An A+ class house:

• consumes up to 40% less heat energy than a B-class equivalent;
• is valued higher on the market;
• has greater opportunities to receive state support or incentives (if provided for in support programs).

In addition, many commercial banks offer better financing terms or “green loans” for buildings that meet A+ or A++ standards. This means that part of the investment can be offset by lower loan interest rates.

“Today, an A+ class house is not a matter of prestige, but a necessity. Investing in efficiency is not a choice – it is a strategic safeguard against energy crises,” says Gediminas Markevičius, an expert at the Housing Energy Efficiency Agency.

Who assesses and certifies energy classes

In order for a building to be officially recognized as A+ class, it must undergo energy performance certification. This process is regulated by a methodology approved by the Ministry of the Environment, and the assessment is carried out only by certified building energy efficiency certification experts listed in the registers of the State Energy Regulatory Council (VERT) and the Construction Inspection.

When is certification carried out?

Certification can be carried out in two stages:

1. Project certification – carried out during the design stage and submitted with the building permit documents. It shows that the project meets the requirements of class A+.
2. Final certification – carried out at the end of construction, before declaring the completion of construction. This certificate is the official document that must be submitted to the Registry Center when registering the building.

The final certificate must be prepared based on the actual situation, including the solutions implemented during construction, the authenticity of the thermal insulation layers, the results of the airtightness test, and other parameters.

What does the expert check?

The expert assesses the following aspects:

• the thermal resistance of the building envelope (based on drawings and actual construction);
• the efficiency of engineering systems (heating, ventilation, hot water supply);
• the airtightness of the building (if a blower door test has been performed);
• the integration of renewable energy sources (if installed).

The assessment is performed using calculation programs and methodologies approved by the Ministry of the Environment. The result is an energy performance certificate indicating the building’s class, actual energy consumption, and justification for the class.

“The certificate is like a technical passport stamp—without it, even the best-designed house remains just a declaration,” says Lina Švedienė, an assessment specialist at the Construction Inspection Authority.

Need help?

The requirements for the A+ energy efficiency class can be complex, ranging from specific thermal resistance standards to heat recovery systems and airtightness tests.

A building permit is one of the most important documents in the entire construction process. Its purpose is to ensure that construction works comply with spatial planning documents, applicable legislation, and building safety and environmental impact requirements. Although certain structures may be built without a permit, it is required for most projects. Correctly assessing the need for a permit is the first step towards a legal and smooth project.

When is a building permit required

A building permit is required for most residential, public, and industrial buildings. The need for a permit is usually determined by the type, size, location, and planned engineering systems of the structure. Even single-family residential buildings require a permit if they exceed the specified parameters or are built in areas with stricter planning requirements.

Classification of buildings according to complexity

According to the Construction Law, buildings are classified into three groups: simple, non-special, and special. The more complex a building is, the more requirements it has to meet. For example, uncomplicated structures may not require a permit in some cases, but this does not mean that there are no requirements at all. From 2021, even smaller structures will often require a permit if they are connected to engineering networks or are built in urbanized areas.

The influence of land-use planning on permits

The need for a permit also depends on the location of the construction. Urbanized areas such as cities, settlements, or collective gardens with approved plans are always subject to stricter supervision. Even a simple, uncomplicated structure in such an area may require a permit. Conversely, in non-urbanized areas where there is no approved detailed plan, less stringent conditions apply, especially when the structure complies with the parameters set out in the STR.

What are the consequences of not complying with the permit?

If construction begins without a permit when it is required, the construction is considered unauthorized. In such a case, the State Territorial Planning and Construction Inspectorate may suspend the work, impose a fine, order the removal of the violations, or even demolish the building. In addition, such a property cannot be registered, used, or declared as a place of residence.

When is a permit not required

Although in most cases a building permit is required, there are legal exceptions for certain categories of buildings and situations where a permit is not required. However, it is very important to understand that these exceptions are clearly regulated and apply only when the builder meets all the specified criteria. Failure to meet even one criterion means that a permit is required.

List of structures that do not require a permit

According to information published by the State Territorial Planning and Construction Inspectorate, a permit is not required for the construction of:

• a simple Group I structure (e.g., a shed, gazebo, greenhouse);
• simple residential buildings up to 80 m² in non-urbanized areas;
• structures not built in the territory of a cultural heritage site;
• objects that are not connected to centralized engineering networks.

However, it is very important to note that all of these conditions must be met simultaneously. For example, if an 80 m² house is connected to the municipal sewage system, a permit is required even if it is built in a rural area.

Common mistakes when thinking that a permit is not required

In practice, there are many cases where builders incorrectly assess their project and start construction thinking that a permit is not required. The most common misconceptions are:

• that a permit is not required if the building is “small”;
• that a permit is not necessary on a garden plot;
• that if the neighbors do not object, everything is legal;
• that construction can be carried out without a permit if the project has been prepared.

In such cases, it is often necessary not only to stop the work, but also to deal with the legal consequences. Therefore, before starting construction, it is necessary to check the need for permits in official sources or contact the municipal architect responsible for spatial planning supervision.

“Not needing a permit is the exception, not the rule. The fewer formal steps, the greater the risk of making a mistake.” – Jonas Žiogas, VTPSI specialist.

How to obtain a building permit step by step

The process of obtaining a building permit is currently digitized and takes place through the electronic service provision system “Infostatyba,” administered through www.planuojustatau.lt. However, although the system is convenient, the process itself requires careful preparation and coordination with various institutions.

1. Design specifications

The first step is to obtain the design specifications. This is a document setting out all the technical conditions imposed by the authorities, which must be taken into account when preparing design solutions. The summary is issued by the municipality or through the Infostatyba system upon submission of an application containing basic information about the planned building and the plot of land.

At this stage, it is important to assess whether the plot is located in a protected area, whether special permits are required from cultural heritage or environmental protection authorities, and whether special plans need to be followed.

2. Design work and coordination

Based on the received summary, technical or simplified project documentation is prepared. This project can only be prepared by certified architects and engineers. The prepared project is coordinated with:

• National Public Health Center (if sanitary aspects are planned),
• The fire and rescue service (if a boiler room or other risk is envisaged),
• The operators of electricity, gas, water supply, and sewage networks (if connections are planned).

Partial projects, such as PV (design proposals), are usually only used when it is necessary to inform the public or obtain additional municipal assessments.

3. Submission of a building permit application

Once all approvals have been obtained, the project is uploaded to the Infostatyba system. This system is used for checking by all authorities, final assessment, and issuance of a decision. The building permit itself is also submitted in digital format and has a unique number.

Once the builder has received the permit, they must keep all documentation during construction and submit it to the Building Inspection Authority if necessary.

“The most common mistake is to think that a building permit is just a formality. It is essentially confirmation that your building complies with all national laws.” – Daiva Petrauskienė, chief architect of the municipality.

How long does it take to obtain a building permit and how much does it cost?

The deadline for obtaining a building permit and the associated costs are among the most frequently asked questions among builders. Although the system is digitized and formal deadlines are set by law, the actual duration often depends on the nature of the building, the quality of the documentation prepared, and the response time of the coordinating authorities.

Permit issuance duration

According to the Construction Law, the municipality has no more than 20 working days from the date of submission of the application with all attachments to make a decision on the issuance of a permit. This applies only when all documents have been submitted correctly and the project complies with the requirements of spatial planning.

However, in practice, the deadline is often extended due to additional comments, corrections, or coordination errors. The process usually takes between 30 and 60 calendar days, including the time required for design, coordination, submission of information via the Infostatyba system, and possible adjustments.

Builders who ensure that all documents are prepared to a high standard and coordinate planning requirements in advance receive their permits more quickly.

Prices and fees

The issuance of a building permit is not subject to tax, but all related services are subject to fees. The largest share of the costs is attributable to:

• design work – depends on the complexity of the building and the scope of the project;
• connection to engineering networks – in some cases, technical conditions must be obtained or connection work must be carried out;
• topographical survey and geodetic measurements of the plot – necessary additions to the project.

In general, preparing and coordinating a project for obtaining a permit for an individual house can cost between €1,500 and €4,000, depending on the region, the design office chosen, and specific requirements.

“The permit itself does not cost anything, but if the project is not prepared properly, you will pay dearly for the lost time,” says Rytis Liekis, a licensed project manager.

Validity, modification, and revocation of the permit

Once you have obtained a building permit, the planning of the work can begin. It is very important to know how long the permit is valid, in which cases it must be modified, and when it can be revoked. These issues are particularly important for longer-term projects or in cases where the project changes after the permit has been obtained.

How long is a building permit valid?

According to the Construction Law, a permit is valid until the start of construction – 5 years from the date of issue. If construction has not started during this period (i.e., no declaration of the start of construction has been submitted or no construction log has been started), the permit automatically expires.

If construction begins within the specified time, the permit is valid for the entire construction process until its completion, even if it takes more than 5 years. However, construction must be carried out in accordance with the approved project.

When does the permit need to be changed?

If significant changes to the project are planned during construction, such as changes to the height, area, purpose, or structural design of the building, it is necessary to prepare design changes and obtain a new permit or amend the existing one.

Minor changes (e.g., changes in color or materials that do not affect technical solutions) usually do not require a change of permit, but it is necessary to consult with the designer or the municipal administration.

In what cases is a permit revoked?

A permit may be revoked in two main cases:

1. On the initiative of the builder – if it is decided to abandon the project, an application for revocation of the permit may be submitted.
2. By law – if construction has not started within 5 years, the permit automatically expires without a separate decision.

The permit may also be suspended or revoked by a decision of the State Territorial Planning and Construction Inspectorate if it is found that it was issued in violation of the law or that the builder has violated the conditions of the permit.

“A permit is not a promise, but a contractual obligation to carry out construction in accordance with the approved plan. Any deviation is a risk,” says Asta Venslovaitė, a lawyer at the Construction Inspection.

Need help?

The building permit system seems simple at first glance, but in reality it involves a lot of mediation, coordination, and risk of error. The legality of the entire building may depend on an improperly prepared project or a missed procedure. If you are unsure whether you need a permit, how to obtain it, or how to properly prepare for the process, the stav.lt team is ready to help.

We can:

• assess whether your project requires a permit;
• help prepare or coordinate project documentation;
• advise on how to use the Infostatyba system correctly;
• explain how to avoid the risk of unauthorized construction;
• help you save time and avoid unnecessary mistakes.

We work with qualified architects, engineers, land-use planning specialists, and former inspectors, so we can ensure a smooth, legal, and fast process from idea to permit.

Nowadays, it is no longer enough to renovate a private house “by eye” – clearly defined legal, technical, and energy requirements must be met. Since 2025, with the update of technical regulations for construction, stricter controls on renovation have come into force: for design, energy efficiency class, and the document submission process. In this article, we will discuss what the Construction Law refers to as renovation, how it differs from simple repairs, and what specific requirements will apply in 2025.

What does house reconstruction mean according to the law?

According to Article 2(44) of the Construction Law, reconstruction is a type of construction where, without changing the purpose of the building, but changing its essential characteristics, construction work is carried out:

increasing or decreasing the volume of the building, changing its height, length, width, structure, engineering systems, or anything else that affects the technical characteristics of the building.

The most important thing is to distinguish between when the work is considered simple repair and when it is reconstruction. For example:

• if you are only replacing windows or roofing, this is simple repair work;
• if you are changing the roof structure, raising the roof ridge, installing an attic or an extension, this is reconstruction;
• if the layout is being changed and load-bearing walls are affected, this is also reconstruction;
• if the foundation structure is being changed or dug deeper than the existing boundaries, this is reconstruction.

Legislation in force in 2025 additionally stipulates that energy requirements apply to the entire volume being reconstructed, even if the work is only partial. This means that “cosmetic” solutions are no longer sufficient – all technical characteristics of the building must be assessed.

“Reconstruction is not a repair, but a structural change. If you change what held or protected the building, you need to coordinate and document it,” says Tomas Paulauskas, construction policy specialist at the Ministry of the Environment.

When is it mandatory to obtain a permit to reconstruct a house?

In 2025, reconstruction of a house without a building permit will be extremely limited and only in exceptional cases. Unlike simple repairs, reconstruction always involves fundamental changes to the structure, so in almost all cases a building permit is required and the process must be carried out through the Infostatyba system.

According to the laws in force, a permit is required when the reconstruction involves:

• changing the dimensions of the building (height, length, width, volume),
• adding new floors (e.g., attic or basement),
• changing the roof structure or angle of inclination,
• the load-bearing structures (beams, columns, foundations) are changed or reinforced,
• the engineering system is reorganized, connected to networks or routes are changed,
• the energy characteristics of the building are changed or the thermal insulation of the entire facade is reconstructed.

Permission is not required only when the reconstruction is carried out in a non-urbanized area, for a simple structure, when the load-bearing structures or the volume of the building are not changed. However, these conditions apply very rarely to individual residential houses.

“If you only change what you can see, it may still be considered renovation. But if you change something that affects the stability or volume of the building, it is considered reconstruction, which is considered unauthorized construction without a permit,” says Rūta Valaitytė, head of the VTPSI control department.

What does the VTPSI check?

In the case of reconstruction, the State Territorial Planning and Construction Inspectorate checks:

• whether the submitted project complies with the type of construction (reconstruction vs. new construction),
• whether the permit was issued legally and whether the construction complies with the project design,
• whether all STR requirements were complied with during the reconstruction (e.g., distances from the plot boundaries, structural strength, energy efficiency standards).

If no permit is submitted or work is carried out without a project, the VTPSI may suspend the work, impose a fine, or require the building to be restored to its original condition.

Energy efficiency requirements for reconstructed houses

From 2025, individual residential houses undergoing reconstruction will be subject to clear energy efficiency requirements, which must be met even if only part of the building is being renovated. State policy in this area is becoming increasingly stringent: the aim is to ensure that renovated buildings are economical, energy-efficient, and meet at least the minimum efficiency threshold.

According to information from the Ministry of the Environment, when renovating a house, it is necessary to ensure that:

• an energy efficiency class of at least B is achieved if more than 25% of the external envelope is renovated;
• insulated structures comply with modern thermal resistance requirements, i.e., walls, roofs, and floors must meet at least the minimum requirements for new buildings;
• windows and doors would be replaced with ones with a heat transfer coefficient that complies with the relevant STR requirements (usually no more than 0.85 W/m²·K);
• the building is airtight and, if the entire volume is being renovated, an airtightness test (blower door) is performed to confirm compliance with the class.

It is important to note that energy efficiency requirements apply to the entire reconstruction project – if an extension is added or the roof is raised, the entire section must comply with the class requirements, regardless of whether other parts of the building remain untouched.

“Every renovation is an opportunity to improve the efficiency of a house. The state supports real energy savings, not cosmetic repairs,” says Lina Juozaitienė, Head of the Housing Policy Division at the Ministry of the Environment.

In addition to energy efficiency, when designing and implementing renovations, it is necessary to ensure that insulation materials, component solutions, and sealing methods comply with modern standards. Improperly designed or executed insulation renovation may prevent a building from achieving the required class, which may become an obstacle to obtaining construction completion documents or support.

Which parts of the building are subject to technical renovation requirements?

When renovating a detached house in 2025, many structural solutions will be subject to stricter supervision and assessment. This means that even seemingly simple work, such as raising the roof or adding an extension, may require a full project design and compliance with STR regulations.

Changes to the facade and volume

Any external change that alters the dimensions of a building – whether it be a change in height, length, width, or volume – is considered a reconstruction and is subject to all relevant requirements. When changing the facade, it is necessary to ensure that compliance with architectural regulations is maintained (if the area is located in a protected zone) and that the insulation layer meets the required thermal resistance. Even if the external wall is increased due to additional insulation, this must be justified in the project.

Roof replacement or reconstruction

Replacing the roof covering may in itself be considered simple repair work. However, if the roof pitch or height is changed, an attic or terrace is added, or the structural layout is changed, this is considered reconstruction. In this case, it is necessary to prepare a project, obtain a permit, and ensure that the new solutions comply with energy efficiency and structural safety requirements.

Redesign of load-bearing structures

One of the most important aspects of reconstruction is whether load-bearing structures are affected. Changing or reinforcing foundations, dismantling or redesigning load-bearing walls, installing additional floors or columns – all this falls within the scope of reconstruction. Such decisions require a technical design of the building, which must be prepared by a certified designer.

If the work affects the mechanical stability of the building, an additional building inspection may be required, especially if the design is prepared after partial demolition or the start of construction.

When is a technical design necessary?

The practice for 2025 is clear: if the volume, structure, or energy characteristics of a building are changed, a technical design is required. A simplified design is only applicable when the reconstruction is minimal, the main parameters of the building are not changed, and this is confirmed by responsible specialists.

“A technical design is not a bureaucratic luxury – it protects the builder from legal, financial, and structural errors,” says Vilius Jakutis, a certified structural engineer.

Project coordination and submission of documents for reconstruction

Even simple house reconstruction requires not only technical preparation but also legal coordination. From 2025, all building permits, including for reconstruction, will only be issued through the Infostatyba digital system, which means that the entire process, from project submission to decision-making, will be carried out electronically.

When is it necessary to submit a project through Infostatyba?

A project is mandatory in all cases where the volume, facade, structural system, or energy class of a building is changed during reconstruction. If the builder plans to carry out reconstruction according to an individual project, it must be prepared by certified specialists and uploaded to the Infostatyba system, where it is reviewed, coordinated, and approved.

This system is also used to coordinate solutions for connection to engineering networks, fire safety solutions and, in certain cases, design conditions. All coordination is carried out within the institutions, but the builder and designer are responsible for the quality of the project.

When is an expert opinion required?

If the structural solutions of the building are non-standard, the planned works affect load-bearing structures, or the object is located in a cultural heritage or special protection zone, an expert assessment of the project may be required. This is carried out by an independent certified expert who assesses whether the construction solutions comply with technical requirements, norms, and safety standards.

Expertise is also necessary if the project was prepared independently, without a qualified architect, but it later became apparent that a building permit was required. In such a case, the municipality may require an additional expert opinion on the suitability of the project.

What documents are required?

When renovating a residential building, the following main documents must be submitted via Infostatyba:

• technical design of the building in PDF format,
• summary of design conditions (if issued),
• topographical photograph and site plan,
• architectural and structural parts,
• engineering system solutions,
• builder’s authorisation, if acting through a representative.

“If you are planning to rebuild the roof, extend the volume or build an extension, the project must be fully developed, approved and uploaded to Infostatyba. Otherwise, there will be legal consequences,” says Gintaras Strelčiūnas, head of the municipality’s architecture and urban planning department.

When building or renovating a residential house, energy efficiency class is not just a formality. Stricter building regulations that came into force in Lithuania in 2021 require all new buildings to meet at least class A, and in some cases even A+ or A++. Therefore, every builder, designer, or renovator must clearly understand what the A class requirements are, how they differ from other classes, and what the main risks are if they are not met.

What does energy efficiency class A mean?

Class A is one of seven energy efficiency classes for buildings, determined by energy consumption for heating, hot water, ventilation, and overall building airtightness. The higher the class, the more energy-efficient the building is.

According to the Technical Regulations for Construction STR 2.01.09:2012, a Class A building:

• must be well insulated, maintaining strict thermal resistance parameters;
• be airtight, i.e., there should be no “leaky joints” between structures;
• be equipped with an efficient engineering system – economical heating, hot water supply, and ventilation.

For comparison: Class B buildings consume more heat, their enclosures often do not meet the required resistance, and Class C houses usually do not meet either airtightness or insulation requirements. Therefore, although Class B is still permissible in some situations (e.g., for renovation), Class A is the minimum requirement for new residential buildings.

“Class A is a turning point between old, energy-inefficient solutions and modern, efficient construction. It is no longer an aspiration – it is a mandatory standard,” says Kęstutis Butkus, a building energy efficiency assessor.

Important: Class A requirements are calculated not only based on insulation materials, but also on the geometry of the building, the heating system, orientation, window and door characteristics, and airtightness.

Class A construction and structural requirements

In order for a residential building to comply with energy efficiency class A, clearly regulated technical solutions must be implemented. These include both the thermal properties of structures and detailed requirements for windows, doors, and installation quality. Based on STR 2.05.01:2013 “Energy efficiency design of buildings”

Thermal resistance of external envelopes

The envelope of a Class A building must retain heat and prevent it from escaping through the structural layers. Therefore, the following minimum thermal resistance requirements apply to walls, roofs, and floors:

• External walls – not less than R = 5.0 (m²·K)/W
• Roof or ceiling – not less than R = 6.0 (m²·K)/W
• Floors on ground – not less than R = 4.0 (m²·K)/W

These parameters can only be achieved by using modern thermal insulation materials (e.g., rock wool, polyurethane, PIR boards), which must be installed consistently, without gaps or cold bridges.

Heat transfer requirements for windows and doors

Windows and doors are structural elements that usually let in the most heat. Therefore, their parameters are strictly regulated in Class A houses:

• Uw coefficient for windows – no higher than 0.9 W/(m²·K)
• Door U-value – no more than 1.3 W/(m²·K)

These indicators must be assessed not only during the design phase, but also during the actual installation of the structures. Windows must be installed tightly, using layered installation technology to avoid even the slightest leaks.

Construction errors that prevent achieving the class

The most common problems that prevent achieving Class A are not related to the design, but to the quality of construction. Improperly joined materials, gaps left at joints, or poorly insulated foundations all reduce the efficiency of a building. Another mistake is insufficient attention to roof or floor insulation, when the entire energy load is transferred to the walls.

“Most often, classes are not achieved due to installation errors rather than materials. No certificate will help if a window is installed with a gap and the insulation is interrupted at the beam,” says Jonas Račkauskas, construction technical supervisor.

Engineering systems and energy efficiency

Although the thermal properties of a building are an essential criterion for Class A, good insulation alone does not guarantee the required energy efficiency. The engineering systems installed in the building – heating, ventilation, hot water supply, and the use of renewable energy sources – also have a significant impact.

Heating system requirements

A Class A house must have an efficient and economical heating system. Although legislation does not prohibit the use of traditional boilers or electric heaters, they must be automatically controlled and meet minimum energy efficiency requirements.

Heating systems with heat pumps (air-water or ground-water) offer the greatest benefits, as their coefficient of performance (COP) often exceeds 3, which means that they produce 3 kWh of heat for every 1 kWh of electricity consumed. This efficiency directly contributes to lower energy demand, which is assessed when calculating the energy performance class of a building.

Ventilation with heat recovery

A mechanical ventilation system with heat recovery is currently an integral part of a Class A building. This system not only ensures high-quality air exchange in the premises, but also reduces heat loss, as the heat from the exhaust air is used to heat the supply air.

According to STR 2.05.01:2013, the design of ventilation systems must be based on the actual needs of the premises, and the heat recovery coefficient (η) of the recuperator should be at least 75%. In other words, the more heat is saved, the greater the likelihood of achieving Class A.

Hot water supply

Hot water systems are also included in the energy performance assessment. The most efficient solutions are solar collectors or combined heat pumps that heat water together with the heating system. The integration of such systems often reduces energy demand and improves the overall class rating.

Verification and documentation of Class A requirements

In order for a building to be classified as Class A energy efficiency, it is not enough to simply declare that warm materials or efficient systems are used. All of this must be substantiated by calculations and official documents that are evaluated by competent authorities.

Energy performance certification

After completion of construction work, the building must undergo energy performance certification. This process is based on special calculations performed by certified building energy performance assessors. The assessment takes into account:

• the heat transfer coefficients of all building envelopes;
• the efficiency of heating, ventilation, hot water supply, and electrical systems;
• the energy demand per square meter per year;
• the amount of renewable energy that can be used (if applicable).

If all data complies with the applicable requirements, an energy performance certificate is issued, indicating the building class from G to A++.

Who performs supervision?

During construction, technical supervision is carried out by a technical supervisor appointed by the builder, but the most important thing for the final assessment is the submission of the building to the State Territorial Planning and Construction Inspectorate. A building cannot be approved for use without an energy performance certificate.

It is important to know that the building inspection authority may reject the building declaration if the actual construction work or materials used do not meet the parameters specified in the project, even if the project theoretically complies with class A.

“Energy efficiency cannot be just theoretical – all solutions must be implemented in reality. Only then will the class be recognized,” says Laima Butkienė, head of the State Territorial Planning and Construction Inspection Department.

Need help?

If you are planning to build a Class A house or renovate an existing building, it is important to comply with all legal and technical requirements from the outset. From the preparation of documents to the actual construction, every decision has an impact on whether the building will meet the mandatory energy efficiency class.

Stav.lt – when construction becomes simpler.

Not all construction projects proceed smoothly or legally. Sometimes residents are faced with illegal construction by their neighbors, illegal extensions, safety violations, or noise, and sometimes the builders themselves violate the rules because they do not understand them. In such cases, you can contact the State Territorial Planning and Construction Inspectorate (VTPSI), which supervises the legality of construction processes in Lithuania.

A correctly and reasonably submitted complaint can not only protect your interests, but also help to stop dangerous or illegal construction. However, it is important to know when to apply, how to do so, and what processes await you.

When to contact the Construction Inspection

The Construction Inspection only accepts complaints regarding violations related to construction activities. This means that complaints must be based on violations of legal acts, not just subjective dissatisfaction.

Typical situations where a complaint is justified:

• a neighbor is constructing a building without a permit or without observing the distances from the plot boundary;
• construction is not being carried out in accordance with the project or the purpose is being changed arbitrarily;
• construction poses a real threat to safety, noise, or the environment;
• reconstruction, renovation, or use requirements are not being complied with;
• the completed building does not comply with the conditions of the permit or is accepted with violations.

Complaints about a neighbor’s behavior, general noise, or aesthetics, if not related to legislation, are not within the competence of the VTPSI. Therefore, before filing a complaint, it is worth analyzing the situation and making sure that specific norms are being violated, such as:

• Requirements of the Construction Law;
• Technical Regulations for Construction (STR);
• detailed or special plans.

“Residents have the right to obtain information about construction work taking place nearby and to report any violations to the inspectorate. This is a sign of civic responsibility,” said a VTPSI spokesperson.

How to file a complaint with the Construction Inspectorate

In order for a complaint to be accepted for consideration, it must be submitted in accordance with the established requirements and channels. The VTPSI provides the opportunity to report possible construction violations either with personal data or anonymously – this is called a hotline.

Ways to submit a report

Complaints can be submitted in several ways:

• by email to linija@vtpsi.lt (applies to both named and anonymous reports);
• by filling out the form online on the hotline page;
• by registered mail or by physically submitting a letter to the VTPSI address;
• via the e-delivery system or using the e-government gateway;
• verbally by telephone, but in this case the complaint will often not be considered official without additional written confirmation.

If you wish to submit an anonymous report, you must indicate this clearly, but it is important to understand that:

“Anonymous reports are investigated only to the extent possible based on the information provided, and no information about the progress or outcome of the investigation is disclosed,” as stated in the VTPSI Trust Line rules.

What information must be included in a complaint

In order for a complaint to be investigated, it must contain at least the following information:

• the specific address or location of the possible violation;
• as clear a description of the situation as possible – what is being built, what is suspicious, which laws or STRs may have been violated;
• when the violation was noticed;
• photos or other evidence (if available).

If the complaint is submitted by a natural person who is not anonymous, their first name, last name, and contact details must be provided. Anonymous complaints are only considered when there is sufficient information to initiate an investigation.

How the inspection authority investigates complaints

Once a complaint has been submitted, it is registered with the Construction Inspection Authority and the official investigation process begins. In accordance with the Rules of Procedure for Administrative Cases, the inspection authority must assess the information provided and take action if there are grounds to believe that the law has been violated.

Initial analysis of the complaint

First of all, it is checked whether the complaint meets the formal requirements: whether sufficient data has been provided, whether specific facts have been indicated, and whether the location and building can be identified. If the information is insufficient, the applicant may be asked to provide additional information. If the complaint is anonymous, it is examined only to the extent permitted by the information provided.

The VTPSI may also refuse to examine a complaint if:

• it does not fall within the competence of the inspectorate;
• it is manifestly unfounded;
• the information duplicates investigations already underway;
• the report was submitted outside the period of validity of the legislation currently in force.

On-site inspection

If the complaint is justified, the inspectorate may initiate an investigation of the facts. This often means that specialists go to the specified location and assess the situation on site: they check the building documentation, permits, distances, structures, intended use, etc. The inspection may be carried out without prior notice, especially if the violation poses a threat to human safety or the environment.

After the inspection, an inspection report is drawn up, recording the facts established. If violations are found, administrative proceedings are initiated.

Notification of the result

If the complaint is submitted by name, the VTPSI shall inform the complainant of its decision or actions within the period specified by law (usually 20 working days). If a longer investigation is necessary, the deadline may be extended, but the applicant will be informed accordingly.

“Our goal is not to punish, but to ensure that construction is carried out legally. Therefore, each complaint is examined based on the facts, not emotions.” – VTPSI Public Relations Department

Possible decisions and actions following a complaint

If, after investigating a complaint, the State Territorial Planning and Construction Inspectorate finds that construction legislation has been violated, various measures may be applied. The nature of these measures depends on the extent and nature of the violation, its consequences, and whether the violation is corrected voluntarily.

Warning or mandatory instruction

If the violation is not serious or does not pose a threat, the inspectorate will often first issue a warning or a mandatory order to remedy the violation within a certain period of time. This may include the removal of illegal fences, extensions or advertising structures, the adjustment of distances, etc.

Administrative liability and fines

If the violation is considered serious or repeated, administrative liability is imposed in accordance with the Code of Administrative Offenses. Fines may be imposed:

• for construction without a permit;
• for deviation from the project without approval;
• for using a building for purposes other than those for which it was intended;
• for starting reconstruction work without a project or permit.

The amount of fines depends on the severity of the violation – for individuals, they usually range from EUR 150 to EUR 5,000, and for legal entities, they may be even higher.

Suspension of construction or obligation to demolish

One of the most severe decisions is the suspension of construction work. This applies in cases where construction is carried out without a permit and poses a threat to safety or the environment. If the violations are not remedied after the suspension, the VTPSI may apply to the court for an order to demolish the building or part of it.

This is particularly relevant in cases of unauthorized construction in urbanized areas or protected zones. In such cases, the inspectorate can act very quickly, especially if there are complaints from the public or public outcry.

“The most severe decisions are only applied when the violations are systematic, malicious, or pose a danger. This is not common practice, but it is always possible if the builder ignores the law.” – VTPSI Legal Department Advisor

What to do if your complaint is rejected

Not all complaints result in action by the inspectorate. Sometimes the VTPSI may decide that the facts stated in the complaint are not confirmed, that no violations have been committed, or that the builder is acting in accordance with the applicable legislation. In such cases, a response is provided regarding the rejection of the complaint, but this does not mean that the applicant has no further options.

Right to appeal against the decision of the inspectorate

Under the Administrative Procedure Law, any person has the right to challenge a decision of a public administration body (in this case, the VTPSI). This can be done by:

• submitting a complaint within 1 month of receiving the response;
• addressing the complaint to the Ministry of the Environment as the higher authority;
• or by directly contacting the Administrative Court.

The court may order the VTPSI to conduct an additional investigation, declare its refusal unlawful, or annul the decision if it finds that it was based on incomplete or incorrect information.

Other actions

If the complaint is rejected on formal grounds (e.g., lack of data, inaccurate description), a new, revised complaint may be prepared. This is particularly important if additional evidence emerges between the submission of the complaint and the investigation: photographs, witnesses, public data.

It is important to know that the complaint system is not just for “submitting inquiries” – each complaint is evaluated responsibly, so a well-founded, accurate, and clear complaint is much more likely to be not only accepted but also resolved.

“In the event of rejection, it is not emotions but additional facts that can change the situation. Sometimes a single photograph showing a significant violation is enough.” – Head of the Complaints Investigation Division, VTPSI

Need help?

The building inspection complaint system can seem complicated: you need to gather evidence, accurately identify the violation, and know when your complaint will be investigated and when it will be rejected. This is why many people do not dare to complain, even though construction violations have a direct impact on their quality of life.

Our specialists can:

• analyze whether your situation falls within the competence of the VTPSI;
• help you prepare an accurate and legally sound complaint;
• advise you on what documents and evidence to include;
• recommend what to do if your complaint is rejected;
• accompany and represent you in your dealings with government agencies.

If you are facing illegal construction, violations on neighboring plots, or want to ensure that your rights are protected, contact stav.lt. Together, we can stop illegal actions and ensure transparency in construction.

A building permit is one of the most important documents proving that construction work is being carried out legally. However, having a permit does not mean that everything is being done properly: construction may exceed the permitted limits, be carried out after the permit has expired, or without any document at all.

It is sometimes necessary for builders, neighbors, or community members to verify that a permit has actually been issued, that it is valid, and that construction is being carried out in accordance with the terms of the permit. This is particularly relevant when:

• construction work is starting next to your property;
• you want to buy or renovate a property and are checking the documents;
• there are suspicions of unauthorized construction or exceeding the limits of the permit.

When and why it is worth checking a building permit

Checking a building permit is not just a formality—it is an important step in ensuring that the construction:

• is carried out legally and without violating your rights as a neighbor or community member;
• complies with urban planning, environmental, and safety requirements;
• does not pose a threat of unauthorized construction, which could lead to legal disputes.

Verification is also necessary for the builder themselves – when a project has been suspended and resumed after a long period of time. Building permits are valid for a limited period of time, so resuming construction after the permit has expired may be considered a violation.

“Residents have the right to know whether their neighbors’ construction is legal. An inspection is not a conflict, but a way to protect your rights,” says Dalia Kazlauskienė, a representative of the State Territorial Planning and Construction Inspectorate.

How to check the validity of a building permit online

Modern information systems allow every resident or specialist to check whether a specific building has a valid building permit. This can be done quickly and free of charge – you just need to know which portal to use and what information to search for.

Infostatyba

The system supervised by the State Territorial Planning and Construction Inspectorate Infostatyba is the main source of information on building permits issued. Here you can:

• search by building address or plot number;
• find the date of issue of the permit, the designer’s details, and the start and end dates of the work;
• see the status of the permit (valid/suspended/expired).

Electronic services portal (E. statyba)

Alternatively, you can use the Electronic Services Portal, which provides not only permits, but also the progress of project coordination, declarations on the start of construction and completion of the building.

To check the validity of a permit:

1. Open the website www.planuojustatau.lt.
2. Select the section “Information about permits.”
3. Enter the address or unique object number (if known).
4. Check the status of the permit, the date of issue, and the validity period.

What does the status of the permit indicate?

• Valid – the permit is active and construction can be carried out legally.
• Suspended – the inspection authority has temporarily suspended the permit until the violations or deficiencies are resolved.
• Expired – the permit has lost its legal force and construction under it is no longer possible.
• Revoked – the permit has been revoked, and the work is considered illegal.

“Infostatyba has become an integral part of public control – every resident can check whether their neighbor is building legally.” – Head of the Digitization Department at the Ministry of the Environment

What data is needed for verification

Although information systems allow public access to building permits, a successful search requires at least some specific data about the building or land plot. The more accurate the information, the faster the result.

Essential data for searching for a permit

• The address of the building is the most important search criterion. It is best to provide the full address: street, number, city or town. Searching by an incomplete or approximate address often yields no results.
• The unique number of the plot – the so-called cadastral number, which can be found in the documents of the Register Center or in the real estate extract. This is useful when the address is not officially assigned.
• Name or surname of the builder (client) – if the permit is issued to a specific person or company.
• Details of the designer or contractor – useful information if the project participants are known.

This information allows you not only to check the validity of the permit, but also to find out what project has been approved, whether the permit allows specific works (e.g., construction of an extension, reconstruction, change of purpose) and whether they comply with the construction work being carried out.

“If you see work in progress but the address is not yet official, the cadastral number is the only accurate way to identify the property.” – Registry Center consultant

What does it mean if the permit is valid but the construction raises doubts?

Even a valid building permit does not guarantee that all work is being carried out in accordance with the legal requirements. A building permit allows specific work to be carried out in accordance with an approved project, but does not allow for arbitrary deviations from the project or violations of its conditions. Therefore, there are cases where construction raises doubts among neighbors, even if the documents formally exist.

Deviations from the approved project

The most common problem is when construction is carried out differently than planned in the project. Changing the location of windows, increasing the area of a building, or adding an additional roof without new approval is a violation. In such cases, the construction no longer complies with the content of the permit and may be considered illegal.

Incorrect type of permit

Sometimes a permit is issued for reconstruction, but the builder actually carries out completely new construction. This violates the essence of the permit and may be equated with unauthorized construction. The exact type of permit (new construction, reconstruction, renovation) must correspond to the actual work.

Expired permit

A building permit is valid for 3 years from the date of issue if construction work does not commence during that period. If work commences on time, the permit is valid for another 5 years. After these periods, the permit expires and the work can no longer be carried out. Extension is possible only in accordance with the procedure laid down in the legislation.

“Having a permit is not a ticket to do whatever you want. Even a minor change without approval can become an administrative offense.” – VTPSI State Construction Supervision Department

What to do if you cannot find the permit or it looks suspicious

If you cannot find the building permit in public databases or notice discrepancies between the actual work and the documents, it is important to act responsibly, as this may indicate possible violations of the law.

The first step is to conduct an additional check

If you are unable to find the permit information yourself, it is worth contacting the State Territorial Planning and Construction Inspectorate (VTPSI). This can be done by:

• filling out a request via the Infostatybos portal;
• submitting an e-mail inquiry to the inspectorate with the specified address or cadastral number;
• by inquiring at the municipal architecture department that approved the project.

The inspectorate has the right to provide information about the validity of the permit and its essential conditions.

What to do if you suspect unauthorized construction

If you suspect that construction is taking place without a permit or in violation of the project, you can file an official complaint with the VTPSI. This can be done:

• by email at linija@vtpsi.lt;
• through the trust line system;
• by filling out a complaint form through the E. valdžios vartai portal.

It is important to provide as much information as possible: the address of the building, the nature of the work, when construction began, and how you believe it violates the law.

“Even a small extension or shed may be illegal if it requires a permit but one has not been issued.” – Marius Rimkus, Chief Architect of the Municipality

Construction is a process that involves technical solutions, physical work, and various risks. From accidents on the construction site to damage to the surrounding area, every stage can bring unexpected losses. This is why the question of whether construction insurance is necessary is being asked more and more often. And if so, in which cases is it mandatory, and when is it only a recommendation?

Construction insurance in Lithuania is not just a matter of good will – in some cases, it is strictly mandatory under applicable laws. On the other hand, even when insurance is not mandatory, it can help you avoid significant financial losses. In this article, we will explain how to find out if you need insurance, what it covers, and how to choose it responsibly.

Why is it important to insure yourself during construction?

It is almost impossible to avoid risks during construction—even if the work is carried out responsibly, there is always the possibility that something unexpected will happen. For example, structural elements may be damaged by an unexpected storm, or neighbors’ property may be damaged due to negligence.

Insurance during construction is not only protection against unforeseen events, but also a way to protect yourself from financial liability when damage is caused to third parties. Both small individual construction projects and large objects have one thing in common – any mistake can cost thousands of euros or even more.

Another important reason is legal regulation. In some cases, insurance is a prerequisite for construction to be considered legal. If an accident occurs during construction and there is no insurance, the responsibility lies with the builder or contractor.

When is construction insurance mandatory?

Construction insurance is mandatory when work is carried out that poses a greater risk to builders, the environment, or people. According to the law, insurance is required in the following cases:

If new construction, reconstruction, major repairs, renovation (modernization), or demolition work is being carried out. In such cases, it is necessary to have both construction insurance and civil liability insurance.

Insurance is also necessary when dealing with cultural heritage buildings, even when carrying out technical or conservation work. The risks are often even greater in such objects, and the liability is more stringent.

The insurance obligation also depends on how the construction work is carried out:

• If all work is entrusted to a single contractor, they must take out an insurance contract.
• If the work is carried out on a farm basis (i.e., the owner carries out the work himself or hires separate craftsmen), the builder must take out an insurance contract.
• If a mixed method is used, with part of the work being carried out by the owner and part by contractors, the builder is also responsible for insurance.

Insurance policies are also mandatory when submitting construction completion documents, without which it is not possible to properly register a building or object.

When is construction insurance not mandatory?

Insurance is not necessary in all cases. There are situations where it is only recommended but not required by law.

For example, when simple repair work is carried out that does not change the structural design and does not create additional loads.

Such work can be carried out without a permit and, therefore, without insurance.

Insurance is also not necessary when constructing or demolishing a simple building (e.g., a farm building or greenhouse) whose area, height, and purpose do not exceed the established standards.

When only equipment installation work is carried out (without physical intervention in the structures), insurance is also usually not required.

However, even if the law allows you to do without insurance, it is worth assessing the risks – if the value of the work is high or the construction site is close to other buildings, additional protection may be a wise decision.

What are the types of construction insurance?

Construction insurance is generally divided into two main categories, which are often required by law but also logically complement each other. Each of them protects against different risks, so it is best to have both.

Construction work insurance

This is a type of insurance that covers all losses related to the construction process. The object of insurance is both the building under construction and the materials or equipment at the construction site.

The purpose of this insurance is to compensate for damage caused by unexpected and sudden events:

• fire or explosion,
• natural disasters (rains, storms, earthquakes),
• theft or vandalism,
• damage due to unintentional errors.

It is important to note that construction insurance is only valid for the construction period specified in the contract and only for those objects that are clearly included in the insurance contract. If construction is delayed, you should arrange for an extension of the insurance.

Civil liability insurance

This is another essential part of construction insurance. It is designed to protect against damage that may be caused to third parties, both individuals and legal entities, during construction. For example:

• if a neighbor’s basement is flooded due to incorrectly designed drainage,
• if an object falls from scaffolding and injures a passer-by,
• if an object near the construction site is damaged (e.g., part of a fence).

Civil liability insurance amounts are usually regulated – they cannot be lower than certain limits. However, depending on the size of the project or the risks involved, it is worth choosing a higher amount of coverage.

Additional insurance coverage

In some cases, builders choose additional coverage to further reduce financial risk:

• Warranty period insurance – protects against defects that become apparent after completion of construction.
• Construction site equipment and machinery insurance – if you have expensive equipment on site, it is worth insuring it separately.
• Employee accident insurance – although formally a separate area of insurance, it is very common in construction.

How to choose the right insurance option?

When choosing construction insurance, it is important to consider the nature of the specific project, its value, duration, and risks. There is no one-size-fits-all policy – the best solution is the one that best suits your situation.

First, you should determine:

• What types of insurance do you need? If you are building from scratch, you will need both construction and civil liability insurance.
• What is the value of your construction project? The higher the value, the higher the insurance amount should be.
• Where is the construction taking place? If there are residential buildings or public infrastructure nearby, the liability risk increases.
• How long will the construction take? The insurance period must correspond to the actual work schedule – if the work is delayed, you may need to extend the insurance.

It is also worth consulting with independent experts – they can help you avoid choosing overly expensive or insufficient insurance, assess the risks objectively, and select the insurer with the best terms and conditions.

Conclusion and advice

Construction insurance is not just a formality – it protects you from significant losses, legal liability, and even forced suspension of construction. Although it is mandatory in some cases, in other situations it is simply a wise choice. It is worth finding out what requirements apply to your specific project and assessing all possible risks.

The most important thing is not to leave your financial security to chance. Insurance during construction helps you feel more secure and, in many cases, avoid legal problems.

Frequently asked questions about construction insurance

A building permit is one of the first steps that anyone planning to build, renovate, or otherwise alter a structure must take. Although it may seem like a mere formality, this document actually marks the beginning of the entire process of legalizing the construction. The permit confirms that the planned work complies with applicable laws, land use planning, protection zones, and technical regulations for construction.

Many people have natural questions: Do I really need a permit? How much will it cost? How long will it take? How can I remember to renew it? In this article, we will answer all these questions and explain how to prepare for the permit application process while avoiding unnecessary mistakes and delays.

When is a building permit required?

A building permit is not required in all cases – it depends on the nature of the construction, the size of the object, and its location. Generally speaking, the more complex the structure and the greater its potential impact on the environment or neighbors, the more likely it is that a permit will be required.

A permit is mandatory when planning to:

• construct a new residential or public building;
• reconstruct a building by changing its external appearance or load-bearing structures;
• carry out major repairs;
• demolish larger structures;
• construct commercial buildings, even if they are small in size.

However, there are exceptions when a permit is not required. For example:

• when carrying out simple repairs (without changing the structure or layout);
• when constructing simple structures up to a certain height and area (e.g., gazebos, sheds);
• when construction is carried out outside the city limits and does not violate the rights of others.

If you are unsure whether your planned construction requires a permit, it is always best to consult with specialists or your local municipal planning department.

How to obtain a building permit?

Obtaining a permit is not as complicated as it may seem at first glance – the most important thing is to be well prepared and know what steps to take. The main system through which the entire process is carried out today is the Infostatyba information system, where permits are issued by municipalities or other institutions.

Steps to obtain a permit:

1. Prepare the project – you must have a building design prepared by a qualified architect or designer. This is the main document without which a permit will not be issued.
2. Submit your application in the Infostatyba system – once you have logged in via the electronic government gateway, you can submit all documents and applications electronically.
3. Wait for approval from the responsible authorities – depending on the location and specifics of the object, the project may need to be approved by the fire department, environmental protection, heritage protection, etc.
4. Obtain a permit – if all documents are in order and do not violate any laws, the permit will be issued electronically.

Who can submit an application?

An application for a permit may be submitted by:

• the builder (land owner),
• an authorized person (e.g., architect or company),
• co-owners – all must give their consent if the land is jointly owned.

What are the deadlines for issuing a permit?

It usually takes 20 to 30 working days to issue a building permit, but this period may be extended if documents are missing, additional coordination is required, or the project does not comply with the standards. It is important to prepare well in advance to avoid delays.

How much does a building permit cost?

The cost of a building permit depends on several key factors, including the type of property, the size of the building, the location, and the complexity of the design. It is important to understand that the permit issuance service itself is usually free, but costs arise from design work, preparation of mandatory documents, coordination procedures, and expert opinions, if required.

The main costs associated with obtaining a permit are:

• Design services: can range from €500 to several thousand euros, depending on the complexity of the building and the architect’s fees.
• Geodetic and topographic measurements: ~€150–500.
• Energy performance project (if required): ~€100–300.
• Mandatory coordination and conditions for connecting to engineering networks: often free of charge, but in some cases additional fees may apply.
• Building design expertise (if necessary): mandatory for some more complex objects – the price can range from €300 to €1,000 or more.

It is important to note that the municipality issues building permits free of charge, but everything that is required prior to this is subject to fees charged by private service providers (designers, surveyors, etc.).

Therefore, the total cost of obtaining a permit, even for a simple single-family house, often exceeds €1,000–1,500. For more complex projects, this amount may double or increase even more.

How to extend the validity of a building permit?

A building permit is valid for 3 years from the date of issue. During this period, construction must begin, i.e., actual work on the land or structures must commence. If construction does not begin within the specified period, the permit expires.

However, it can be extended.

When and how can this be done?

• The permit can be extended no later than 3 years after its issue.
• The application must be submitted via the Infostatyba system, logging in as a natural or legal person.
• The permit can be extended only once, and it is extended for another 2 years.

What documents must be submitted?

Usually, the following is sufficient:

• a reasoned request for extension,
• an explanation of why construction has not started,
• a copy of the valid building design (if it has not changed).

Does it cost anything?

The permit extension procedure itself is free of charge, but additional costs may arise if the design needs to be updated or new approvals are required.

Common problems and how to avoid them

Obtaining a building permit does not usually cause any major difficulties, but many people still encounter obstacles that slow down the process or require additional time and expense. Problems most often arise due to insufficient preparation or incorrect assumptions that “everything will be simple.”

Incomplete or inaccurate documentation

This is one of the main obstacles that cause authorities to reject or suspend the examination of an application. Often, clear topographical plans are missing, technical drawings are incorrect, or project information is not properly formulated. Sometimes the data provided does not correspond to the actual situation on the site.

How to avoid this: consult an experienced designer and use the services of professional architects. It is also a good idea to check the list of documents at Infostatyba before submitting your application.

Design errors

Even a minor error in a drawing – too close to the boundary of a neighboring plot, incorrectly marked easement, or unresolved engineering network issues – can cause the authorities to reject the application or request corrections. Such “minor” corrections often take weeks.

How to avoid this: Before starting the design, find out all the specific features of the plot, from detailed plans to infrastructure requirements. It is worth involving a technical consultant in the design stages.

Missing the permit validity deadline

Often, a permit is issued, but construction does not begin within three years, and the permit expires. This happens especially often when builders are waiting for financing, coordinating contractors, or simply do not have enough time.

How to avoid this: enter the permit expiration date in your calendar or reminder system. If you know that construction will be delayed, submit a request for an extension before the permit expires.

Non-compliance with municipal zoning

Sometimes a project does not comply with the specific purpose of the territory or the planned zoning documents. In this case, the plan must be adjusted or even the intended use of the plot must be changed.

How to avoid this: before designing, check the detailed plan of the plot, special land use conditions, heritage protection or other restrictions.

People’s experiences: what you should know in advance

Many people who have already gone through the process of obtaining a building permit agree that the most important thing is to plan everything in advance. Some say that they obtained their permit in a matter of weeks, while others say that minor errors delayed the process for months.

Here are some of the main practical tips:

• Do not attempt to “coordinate everything yourself” if you do not have experience – this often only makes the situation worse.
• Check that the project complies with STR requirements (technical regulations for construction) – this is a common reason for rejection.
• Communicate with the municipality – if you have any questions, it is better to ask than to submit incorrect information.
• Use the Infostatybos system consciously – carefully monitor the status of your application and respond to comments.

Practice shows that when experienced specialists (designers, consultants, construction supervisors) are involved in the process from the outset, everything runs more smoothly and cheaply.
