Maintenance & repair duties 3 min read · published September 11, 2025

As a tenant in Finland, it is important to know what to do if you discover a leak or mold damage in your home. This guide explains simply the responsibilities of landlords and tenants, how to notify the landlord, and when you can demand repairs or compensation. The content emphasizes practical actions: documentation, repair requests, deadlines and, if necessary, dispute resolution through legal channels. If the problem affects the habitability of the home, act quickly and keep all messages and photos. The guide also refers to the housing-related legislation and official guidance that you should review before taking further steps.[1][2]

What the tenant should do immediately

When you notice a leak or mold, make a clear written notification to the landlord (email or text message with backup). Describe the damage, add photos and propose a suitable time for a repair visit. Keep messages and receipts, as they serve as evidence in possible disputes.[1]

Take photos immediately and add dates to the images.

Repair responsibility and timelines

The landlord generally has the obligation to maintain and repair the dwelling to keep it habitable. Minor repairs may fall to the tenant if agreed in the lease, but moisture and mold issues typically fall under the landlord's responsibility. Notify the issue in writing and request a response within a reasonable time.

Respond to repair requests in writing so deadlines are documented.

When you can demand rent reduction or compensation

If the dwelling is not habitable and repairs are not made within a reasonable time, the tenant may be entitled to a rent reduction or compensation. This requires documentation and giving the landlord an opportunity to remedy the situation. If necessary, you can seek resolution through the Consumer Disputes Board or the courts.[2]

Evidence and documentation

  • Take detailed photos and write a dated description of the damage.
  • Send the repair request in writing and keep copies of messages.
  • Keep receipts for any temporary repairs or accommodation costs.
Good documentation increases your chances of receiving compensation or a rent reduction.

Resolving disputes

Try to reach an agreement with the landlord first. If the matter cannot be resolved, you can file a complaint with the Consumer Disputes Board or bring the case to a district court. Before legal action, collect all messages, photos and any expert statements.
