When can you request a rent reduction?

If a defect reduces the usable value of the apartment or hinders use, a tenant can demand a rent reduction. Legal bases include the Act on the Protection of Tenant Rights and provisions of the Civil Code[1][2]. It is important to define the extent of the defect and the expected economic effect.

In most cases the reduction is proportional to the loss of usability of the apartment.

How to prepare documents and evidence

Collect dated photos, emails and inspection reports. Prepare a clear description of the defects, include dates and repair costs if known. Documents increase the credibility of your claim.

Keep receipts, photos and correspondence with the landlord.

Procedure and deadlines

The process usually starts with a written demand to the owner proposing a reduction and a deadline for fixing the defects. If the response is negative or there is no reaction, the next step may be a civil lawsuit. Remember evidence deadlines and keep copies of all letters and delivery confirmations.
