Enforcing Rent Reduction Rights for Tenants in Germany

Many tenants in Germany face the challenge of enforcing a rent reduction claim against their landlord when the apartment has defects or the heating fails. This guide explains in plain language how, as a tenant, you can document your claim, which deadlines apply, and which official forms and proofs are useful. We describe practical steps such as defect notification, documentation of damage, calculating rent reduction and correctly submitting letters to the local court. The goal is to give you concrete actions and appropriate authority links so you can assert your rights safely and effectively.

What is a rent reduction claim?

A rent reduction claim allows tenants to reduce rent if the rental property is defective (e.g., heating failure, mold, water damage). The legal basis is in the German Civil Code (BGB), particularly the provisions on rent reduction and the landlord's duty to maintain the rental in a contractually agreed condition.^[1]

Legal basis and competent courts

For rental disputes, the local court (Amtsgericht) is usually competent; for legal questions and precedents, higher regional courts and the Federal Court of Justice are relevant. Pay attention to limitation periods and civil procedure rules if eviction or payment lawsuits become necessary.^[2]

Documents and evidence to collect

• Photos with dates of the defects (photo)
• Correspondence with the landlord, emails and messages (document)
• Written defect notification with a deadline (notice)
• Witness statements or logs (record)
• Receipts for additional costs, e.g. emergency heating (rent)

Practical steps: sample workflow for tenants

1. Report defects in writing and set a deadline (notice)
2. Collect evidence: photos, dates, witnesses, measurements (photo)
3. Calculate rent reduction and document the amount (rent)
4. If no solution: prepare a lawsuit or application at the local court (court)

Forms and official templates

Use only official forms or clearly structured sample letters. Examples include defect notification and sample letters for rent reduction; templates and legal texts for tenancy procedures can be found at official sites for orientation.^[1]
