Building permit or statement

A building permit is required for constructing a new building, extending an existing building or for major renovation projects. If your project involves a minor repair or modification to a building or technical solution, a building permit is not necessary. In this case, a statement can be prepared instead.

A building permit are required for the construction a new building or extending an existing one. A building permit is also necessary when adding a new floor to an existing building, substantially changing the use of the building or carrying out a major renovation project.

A construction project also requires a building permit if the work has an impact on the safety or health of the people using the space. Examples include construction projects in attic spaces, pipe renovations and sauna construction projects.

A preliminary negotiation must always be held for a project requiring a building permit. You can request a preliminary negotiation by clicking on "Kysy neuvoa (Ask for advice)" in the Lupapiste online permit service.

Projects that involve minor repairs or modifications such as creating a new doorway or installing a fireplace and chimney are assessed on a case-by-case basis to see if a statement is sufficient or if a building permit is necessary.

When you first register as a user of the Lupapiste online permit service, you can mention that you are applying for a Z statement in your project description. Once you have filled in your registration application and saved the related attachments and plans in the service, the designer who prepared the project drawings will book an appointment with the inspection engineer responsible for the area in question. During the meeting, the inspection engineer will assess whether a statement is sufficient or if a building permit is necessary.

Apply for a building permit and statement before you start your construction project.
