Enforce Defect Notice: Tenants in Germany

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

Many tenants in Germany find that defects in their apartment are remedied slowly or not at all. This article clearly explains how to write a formal defect notice, which deadlines and formulations are common, and how to document damage properly (photos, date, witnesses). You will receive concrete template letters, practical advice on rent reduction and a step‑by‑step guide before formal action such as a lawsuit at the local court becomes necessary. The aim is to empower tenants without legal background: set deadlines, strengthen evidence and know which laws apply. Keep files, receipts and communications ready so you can assert your rights in Germany effectively and factually.

What tenants should do immediately

If you discover a defect, notify the landlord in writing and set a clear deadline for repair. Specify the defect points precisely and request repair within a reasonable period. Refer if necessary to the landlord's statutory duties under the BGB [1] and document every step of communication.

  • Send a written defect notice to the landlord and document receipt.
  • Set a deadline: specify a reasonable deadline (e.g. 14 days) and make the deadline clear.
  • Secure evidence: photos, videos with dates, written messages and witness names.
  • Urgent repairs: take short-term measures for acute hazards and keep cost receipts.
  • Check rent reduction: for significant impairments a reduction rate may apply; document extent and duration.
  • Final step court: if the landlord does not respond, proceedings at the local court may be necessary [3].
Detailed documentation increases your chances in disputes.

Forms, templates and practical examples

There is no single nationwide official defect notice form; a clear template letter that you send by registered mail or email is often sufficient. Examples include:

  • Template defect notice: describe the defect, requested remedy and deadline (e.g. 14 days).
  • Record list: attach photos, dates, times and witness names.
  • Eviction claim / court forms: filed at the local court if the landlord does not comply [3].
Respond within set deadlines or rights may lapse.

Example: Short template text

"Dear Mr./Ms. X, since DD.MM.YYYY the following defect exists at Address: [description]. Please remedy the defect by DD.MM.YYYY. If no remedy occurs, I reserve the right to reduce the rent and initiate legal action."

Rights, rent reduction and legal basis

Tenant rights are regulated in §§ 535–580a BGB; in particular the landlord's duty to maintain the property is relevant [1]. If the defect significantly impairs usability, the rent may be reduced. Before reducing rent, document scope and period of the defect and inform the landlord in writing.

For court action, the rules of the Civil Procedure Code (ZPO) apply and local courts are competent for tenancy disputes [2][3].
