Water Damage: Rent Reduction for Tenants in Germany

As a tenant in Germany it is important to detect water damage early and document it correctly so that a rent reduction can be possible and rights are preserved. This guide explains in plain language which steps you should take immediately: take photos and videos, notify the landlord in writing, observe deadlines and what evidence a court may accept. I describe practical sample formulations, name relevant sections in the BGB^[1] and explain how and when you can calculate a rent reduction. You will also find notes on authorities and jurisdictions as well as links to official forms. The information is aimed at families and single tenants seeking quick, reliable solutions for housing problems in Germany.

What to do in case of water damage?

Act quickly: document the extent and consequences of the damage, inform the landlord in writing and secure evidence for a possible rent reduction or later legal dispute.

• Take photos and videos (photo/video) of the damage immediately and note timestamps.
• Send a written defect notification to the landlord (by registered mail or email with read receipt) and set a deadline.
• Clearly specify deadlines (deadline): set a date for remediation and document the timeframe.
• If there is a health risk, call a specialist or tradesperson for provisional securing and keep cost receipts.

Rights and obligations: rent reduction, deadlines, court

Under the rules of the BGB tenants are entitled to a defect-free dwelling; in the case of significant impairments (e.g. defective heating, mold, leaking water) a rent reduction may be considered.^[1] Court actions are subject to the rules of the Code of Civil Procedure^[2], and decisive interpretations are provided by the Federal Court of Justice.^[3] Inform the landlord in writing, set a reasonable deadline for remedy and keep all receipts.

How is the rent reduction calculated?

• Estimate the reduction share according to the extent of the impairment (e.g. no hot water = significantly higher percentage).
• Compare with court rulings of similar cases or documented reduction examples.
• Keep the reduced amount in a separate account and record date and reason in your bookkeeping.
