Rent Reduction for Defects in Finland

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

What Does Rent Reduction Mean?

Rent reduction means a lower rent in situations where the apartment does not meet the agreed or normal standard of living, for example due to moisture, heating failures, or water damage. A tenant has the right to demand a reasonable rent reduction if defects significantly reduce habitability. This is regulated in residential lease legislation.[1]

A tenant can demand a rent reduction retroactively for the period before repairs.

When Can You Demand a Rent Reduction?

  • Repair requirements and habitability (repair): when the defect significantly reduces living standards.
  • Evidence: photos, messages, repair receipts and other documents (evidence) help support the claim.
  • Notice to the landlord: make a written notification and request repair and rent reduction (notice).
  • Deadlines: give the landlord a reasonable time to fix the defect before taking further steps (deadline).
  • If no agreement: in disputes you can turn to the consumer disputes board or the courts (court).
Keep all receipts and photos organized.

How to Request and Document a Rent Reduction

Start with a written notification describing the defect, its effect on living conditions, and request a specific rent reduction or repair. Attach evidence such as photos, dates and any repair cost estimates. Keep copies of all correspondence and any maintenance requests and invoices.

Respond to written notices within deadlines to avoid legal consequences.

If the landlord does not respond or disputes the claim, you can propose mediation or seek resolution from authorities. The consumer disputes board can handle tenancy disputes, and if necessary the matter can be brought before a district court.[2]

Negotiation and Necessary Legal Steps

Before legal action, try to negotiate with the landlord and agree on repairs or rent reduction in writing. If no settlement is reached, next steps can include getting advice from consumer counseling or filing a complaint with the consumer disputes board and ultimately bringing a case to court. Litigation may require thorough documentation and clear evidence of the defect's impact on living conditions.[3]

Detailed documentation increases your chances of a favorable outcome in a dispute.
