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.

A permit is legally valid if no appeals or complaints have been submitted against the permit decision. An appeal decision made by the Environment and Permits Sub-committee can be appealed to the Helsinki Administrative Court. The appeal period is 14 or 30 days.
You may only start the construction work once the permit becomes legally valid. Projects that have been granted a building permit must begin within three (3) years and the construction work must be completed within five (5) years of the permit entering into force. In the case of action permit, demolition permit or landscape work permit, the work must be carried out within three (3) years.
Be sure to apply for an extension of your permit while it is still valid. If the permit has expired, you will have to reapply for the permit in order to receive an extension.
In Helsinki, all applications for building permits are submitted electronically in the Lupapiste online permit service. General and project-specific guidance and counselling are also primarily provided via Lupapiste. Documents related to the application and construction process monitoring are to be submitted in digital format to Lupapiste.
