You can apply for an action permit instead of a building permit if the construction project involves a small outbuilding or other minor structure. An action permit is also required for some repairs and modifications, such as select facade work and combining and splitting dwellings, as long as the project does not involve demolition or changes to load-bearing structures. Action permits are also required for the construction of a geothermal well or wastewater system.
Building regulations exempt certain projects from the need to apply for an action permit. Visit the "Construction projects instructions" page to check if your project requires a permit.
Apply for a permit before you begin your construction project. To ensure that your project goes smoothly, it is always a good idea to arrange for a preliminary negotiation on the project before submitting your permit application. Preliminary negotiations are requested by clicking on "Kysy neuvoa (Ask for advice)" in the Lupapiste online permit service. In the case of smaller construction projects, the preliminary negotiation can be used to ascertain whether a statement in terms of cityscape is sufficient in lieu of an action permit.

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. Unless an extension is applied for during the permit’s period of validity, you will have to reapply.

General and project-specific guidance and counselling are also primarily provided via Lupapiste.
