Permit fees and permit processing

Most building permits and statements are subject to a fee. The size of the fee is determined by factors such as the size of the building, the scope of the renovation and the location. In Helsinki districts 1–27 and 31, a surcharge of 15 per cent is added to the permit processing fee.   

Examples of processing fees for permit applications:

  • The basic fee for a building permit for one building is EUR 847. A fee of EUR 5.9/m2 is then added to this basic fee.
  • The average fee for an action permit is EUR 648. The fee varies between EUR 363 and EUR 933 depending on the scope of the procedure. An exception is the action permit for a geothermal project, which is free of charge for geothermal wells with a depth of less than 1,000 metres.
  • For detached house construction projects, the city arranges the neighbour consultations at no cost. For other projects, the service costs EUR 399.

Applications receive notification of the decision approvals in the Lupapiste online permit service.  

Permits decisions are officially visible for 14 days. During this period, it is possible to submit an appeal to the Environment and Permits Sub-committee of the Urban Environment Committee.

You can find a list of Building Control public notices in Finnish and Swedish only in the Julkipano (Public notices) section of the Lupapiste online permit service. No login is required to see this list.

A list of public notices and decisions is also on display in the lobby of the Urban Environment House, located at street address Työpajankatu 8, Helsinki.


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.
