Tenant Guide: Water Damage Negotiation in Germany

Dispute Resolution & Rent Reduction 3 min read · published September 07, 2025

A water damage incident in the apartment is a stressful event for many tenants. In Germany your rights are clearly regulated: you should document damage, inform the landlord and, if necessary, demand rent reduction or enforcement of repairs. This practical guide explains step by step how to take photos and records, set deadlines, use official forms and when it makes sense to contact the local court or legal assistance. Language remains clear; legal terms are explained. The goal is that you negotiate calmly with the landlord, secure your claims and avoid unnecessary escalation.

What to do in case of water damage?

Act quickly: secure photos, date and time, note visible damage to furniture and building structure. Also document if heating, electrical systems or plumbing are affected. Many rights are based on the German Civil Code (BGB), especially landlord duties and rules on rent reduction.[1]

Keep all receipts, photos, and a damage log as proof.
  • Photos and log: record date, time, location and visible damage.
  • Written defect notice: Inform the landlord immediately and request repair.
  • Set deadlines: Give a reasonable deadline for repair and announce further steps if necessary.

Rights, rent reduction and deadlines

If habitability is significantly reduced by the water damage, rent reduction may be appropriate. Assess the reduction amount based on the extent of impairment and document duration and scope. There is no official nationwide form for rent reduction; a clear written declaration to the landlord is sufficient. In disputes, civil procedure rules (ZPO) are relevant, especially if proceedings at the local court are required.[2]

Respond promptly to protect your claims.

Evidence and proof

Collect photos, timestamps, witnesses, repair invoices and all communications with the landlord. Keep a simple log with dates and times of every notice to the landlord and agreed measures.

  • Photos and videos: capture affected areas and the extent of damage.
  • Correspondence: keep emails and letters as proof.
  • Invoices: document costs for drying, furniture replacement or replacement purchases.

Practical forms and assistance

For legal assistance, the "Antrag auf Beratungshilfe" (application for legal consultation aid) may be useful; the form is available at local courts or on official justice pages. Legal consultation aid helps when you need financial support for an initial lawyer consultation. There is no special form for rent reduction; a simple written letter often suffices. Further information and sample texts are available on official federal justice sites.[3]

A clear written defect notice increases your chances in negotiations.

Frequently Asked Questions

Can I reduce the rent immediately?
If the use of the apartment is restricted, you can reduce the rent. Document the extent and duration carefully and inform the landlord in writing.
