Tenant Rights: Enforcing Rent Reduction in Germany

Rent & Rent Control 3 min read · published September 07, 2025

Many tenants in Germany face the question of how to enforce a rent reduction when the apartment has defects or agreed amenities are missing. Without a lawyer, this is possible if you proceed systematically: document defects, ask the landlord in writing to remedy them, set deadlines and, if necessary, reduce the rent appropriately or safeguard the difference. This article explains practical steps, relevant legal bases and which documents help in court or at the local court. It is aimed at tenants without legal knowledge and gives wording examples, deadlines and official sources in Germany so you can assert your claim factually and securely. Read on for step-by-step instructions.

What is a rent reduction claim?

A rent reduction claim arises when the rental property has defects that affect its use. According to the rules of tenancy law in the BGB, the rent may be reduced up to the extent of the impairment.[1] In many cases the situation can be resolved without immediate litigation if the landlord is requested to remedy the defect or an amicable solution is found.

The basic duties of landlord and tenant are regulated in §§ 535–580a BGB.

Preparation: Evidence and deadlines

Good preparation increases the chance of enforcing the claim without a lawyer. Collect clear evidence, document deadlines and inform the landlord in writing.

  • Photographically document defects (document, photo).
  • Send a written defect notice and set a deadline (notice, form).
  • Record deadlines: date of notification and deadline for remedy (deadline).
  • Secure payment receipts and previous rent payments (rent, payment).
  • Note witnesses, janitor or neighbors as contacts (call, contact).
Detailed documentation increases your chances in a legal dispute.

Written defect notice: wording and deadline

Write briefly and factually: describe the defect, state the date and request a reasonable deadline for remedy (e.g. 14 days). Name possible consequences, such as rent reduction if no remedy occurs. Send the letter by registered mail or by email with read receipt and keep proof.

Keep all landlord responses, including SMS or emails.

How much can you reduce the rent?

The amount of the rent reduction depends on the degree of impairment and is estimated proportionally in practice. There is no fixed table in the law; courts and BGH case law provide guidance.[3] If in doubt, document the extent and duration of the defect and, if necessary, obtain an estimate or advice.

Reducing rent without prior documentation can lead to repayment claims.

If the landlord does not respond

If the landlord does not respond adequately within the set deadline, you can make a reasonable rent reduction and withhold the reduced amount separately. Another option is to initiate court proceedings at the local court (Amtsgericht), which handles tenancy disputes in the first instance.[2]

Contact the competent local court if an amicable solution is not possible.

Examples: wording

Short template for a defect notice:

  • Dear Mr/Ms X, on DATE the following defect exists: DESCRIPTION. Please remedy the defect by DATE (14 days). If you do not respond, I hereby announce that I will reduce the rent appropriately.
Phrase the letter neutrally and factually, without threats.
