Amendments to Estonia’s Building Code and related legislation, which entered into force on 1 August 2026, are set to make construction and planning processes faster, simpler and more flexible for developers and property owners.

The amendments modernise Estonia’s construction law and reduce a number of procedural and administrative requirements. One of the most significant changes is the expanded role of design specifications, which can now be used in situations where previously an amendment to a detailed spatial plan may have been required.

Design specifications offer greater flexibility

The changes give property owners and developers more flexibility to adapt construction projects without going through a lengthy detailed spatial planning process.

In certain cases, design specifications can now be used to make changes such as adding smaller auxiliary buildings — including saunas, sheds and garages — or modifying a building’s footprint or number of floors.

They can also be used to clarify the type of technical solution or installation. For example, a project may be adapted to replace an electric heating system with a geothermal heating solution.

The expanded role of design specifications is particularly significant because it allows relatively minor changes to be handled through a more proportionate procedure, avoiding the time and resources associated with amending a detailed spatial plan.

Construction procedures become faster and less burdensome

The amendments also reduce a number of administrative requirements across the construction lifecycle.

Key changes include:

  • Building notices are now valid for four years. This gives developers greater certainty when construction schedules change and eliminates the need for repeated notifications to the local government solely because a project has been delayed.
  • Simplified procedures for smaller residential buildings. For detached houses, semi-detached houses and residential buildings with up to two apartments, the previous requirement to apply for a formal use permit has been replaced by a simplified use notification submitted through the Estonian Building Register.
  • Simpler procedures for projects involving several buildings. Where several buildings are constructed as part of one project, separate use-permit applications are no longer required for each building.
  • Small non-residential buildings are subject to lighter requirements. Buildings with a floor area of less than 20 m² can be constructed without a building permit or building notice, provided the applicable design specifications are clarified.
  • Fewer requirements for drilled wells. Prior approval of the location of a drilled well or borehole is no longer required. A building notice and the relevant project documentation are sufficient.

Older buildings can be legalised more easily

The amendments also simplify the legalisation of older buildings that were constructed without a valid legal basis.

For buildings constructed before 1 July 2015, the key requirement for legalisation is that the building is safe.

Buildings constructed before 22 July 1995 are deemed lawful automatically.

In addition, the previous €500 state fee for registering unauthorised buildings has been abolished, significantly reducing the cost of bringing older buildings into the Estonian Building Register.

For property owners, these changes provide a clearer and more accessible route to regularising older buildings and resolving issues that may otherwise complicate the sale, financing or development of a property.

New shelter requirements for larger buildings

Developers must also take into account a new requirement concerning civil defence shelters, which entered into force on 1 July 2026.

The requirement does not apply to all new buildings. Detached houses, semi-detached houses and terraced houses are exempt.

The obligation primarily concerns larger buildings with at least 1,200 m² of enclosed net floor area, including apartment buildings with three or more apartments, office and commercial buildings, accommodation establishments and a range of public buildings.

The legislation nevertheless provides flexibility in how the requirement is implemented. Where permitted by the applicable comprehensive spatial plan, a shelter can be incorporated into a new development by clarifying the relevant design specifications, rather than initiating a separate planning procedure.

A more proportionate approach to construction regulation

Taken together, the amendments represent a move towards a more flexible, proportionate and practical construction-law framework in Estonia.

For developers and property owners, the changes should reduce unnecessary administrative steps while making it easier to adapt projects to changing needs and circumstances. The expanded role of design specifications is particularly important, as it allows a broader range of project changes to be addressed without resorting to a full amendment of a detailed spatial plan.

At the same time, the new shelter requirements introduce an important resilience and civil-defence dimension into the planning of larger buildings.
