Tenant Rent Reduction During Renovation in Finland

Rent & increases (index, fair rent) 3 min read · published September 11, 2025

A renovation in an apartment can affect living quality and the amount of rent, but tenants have rights in Finland. This article guides step by step how to request a rent reduction, what documents to collect and how to negotiate with the landlord. I also explain what kinds of damage or restrictions usually justify a reduction and how the process proceeds before possible authority or court proceedings. The text contains practical tips, deadlines and sample letter templates so that the tenant can act correctly and protect their rights. The aim is to make the process clear and accessible without legal background. In addition, I cover when to seek help from the KKV or consult Finlex provisions and what evidence to collect for potential disputes.

What does a rent reduction mean?

A rent reduction means that the rent is lowered or rent payments are suspended if the apartment does not match the agreed use due to renovation, damage or another significant nuisance. The right usually requires that the nuisance is substantial and that the tenant notifies the landlord and tries to limit the damage. Key regulations can be found in the law on residential leases available on Finlex.[1]

Good documentation improves your chances in disputes.

How is the right to a reduction assessed?

The assessment is based on the nature and duration of the nuisance and how much living is impeded. The landlord has an obligation to maintain the apartment, but the timing of repairs can also affect the right to a reduction. Before filing a complaint, try negotiation and collect clear evidence: photos, messages and possible expert statements. If needed, guidance and advice can be sought from the KKV (Consumer and Competition Authority).[2]

  • Major water damage or mold issue that prevents normal living (repair).
  • Extended heating or water outage due to renovation or repairs (repair).
  • Significant reduction of living or usable space due to renovation (repair).
Respond to the landlord in writing and keep copies of all messages you send.

Frequently Asked Questions

Can I get a rent reduction if the renovation lasts only a few days?
A short-term, minor disturbance usually does not entitle you to a reduction unless the nuisance is particularly significant or fundamentally affects living.
How do I notify the landlord about a rent reduction?
Notify in writing, describe the nuisance and its impact on living, attach photos and propose the amount of the reduction or an alternative solution.
What evidence is important?
Photos, dated messages to the landlord, possible expert statements and expense receipts are useful evidence.

How-To

  1. Record the nuisance immediately and send a written notice to the landlord as soon as possible (deadline: 14 days recommended).
  2. Take photos and keep a chronological log of the nuisances and repair works.
  3. Agree with the landlord on a repair schedule and the need for a reduction by negotiating.
  4. If negotiation fails, send a written claim for a rent reduction and save the evidence.
  5. Seek KKV guidance or contact legal aid before taking legal action if necessary.
Timely action and clear documentation are often decisive in disputes.

Key takeaways

  • Notify the nuisance quickly and preserve documentation immediately.
  • Assess the nature and duration of the nuisance before making a claim.
  • Collect evidence systematically and keep copies for yourself.
