Finland short-term rental regulation and SDEP status

Building Act STR provisions in Parliament Updated 2026-10-30

Finland has consumer, statistics, and city-level accommodation guidance, and its government proposed the first short-term-rental provisions in the Building Act in April 2026: a 90-day annual letting threshold above which a change-of-use permit is required, municipal discretion to raise it to 180 days, and a letting-days record-keeping duty. The bill is still in Parliament and no national registration procedure or SDEP is planned.

What this means

Finland's short-term rental rules develop through accommodation, consumer, building-use, and city-level enforcement channels rather than through a national registration procedure.

Helsinki guidance treats repeated short-term letting as potential accommodation provision rather than ordinary residential leasing.

The government bill HE 83/2026, given to Parliament on 30 April 2026, adds a new chapter to the Building Act with the first short-term-rental provisions: short-term letting is defined as letting a furnished dwelling for less than 28 consecutive days for payment, letting an unoccupied dwelling in a plan area for more than 90 days a year becomes a permit-requiring change of use, municipalities may raise that limit to 180 days, and the holder must keep records of letting days and show them to the building supervisory authority on request. The two short-term-rental sections are proposed to enter into force on 1 January 2027, and Parliament has not yet voted on the bill.

The housing companies amendment that clarifies how housing companies can respond to disturbance from short-term letting entered into force on 1 October 2026.

Implementation status

Statistics Finland maintains an accommodation-establishment register for the scope of accommodation statistics, covering establishments with at least 20 beds in the documented population.

Consumer guidance says individual accommodation services are not covered by a specific accommodation-service statute in the same way as a package travel framework, but consumer protection principles can apply when the provider is an entrepreneur.

Technical interface

No Finland-specific SDEP OpenAPI documentation, source code, sandbox, national STR registration-number validation API, or platform onboarding process is currently available.

Future monitoring should focus on whether national implementation creates a registration workflow or leaves practical controls primarily to municipalities and sectoral rules.
