Safety & Emergency Protections 2 min read · published September 07, 2025

As a tenant in Germany, you should be able to prove that smoke detectors are installed, functional and maintained. This documentation protects you in disputes with the landlord and helps clarify liability issues. In this article we explain clearly which documents are useful, how to store inspection records, photos and maintenance logs securely and when sample letters to the landlord are helpful. We name competent courts and relevant laws as well as forms you may need for complaints or lawsuits. The tips are practice-oriented: you receive concrete wording, deadlines and a step-by-step guide to effectively secure your rights as a tenant in Germany. We also explain how to report defects in writing, set deadlines and which types of evidence courts typically expect. Special attention is paid to high-rise buildings and differences in state building codes.

What counts as documentation?

Relevant legal bases include lease obligations and the BGB (Civil Code) §§ 535–538.[1] Reliable documentation includes:

  • Date-stamped photos of the installation
  • Maintenance and inspection records
  • Receipts for testing devices or services
  • Email and written correspondence with the landlord
  • Witness statements or handover protocols
Detailed documentation increases your chances in court.

How to create and secure evidence

Keep a file with all documents: photos, inspection records, invoices and correspondence. If you consider legal action, procedural rules of the ZPO apply.[2] Practical steps include:

  • Send a sample letter to the landlord by registered mail
  • Set a clear deadline (e.g. 14 days) and state it in the letter
  • Secure dated photos and inspection records
  • Have a professional inspect if needed and keep the invoice
  • Contact a tenants' association or legal advice before suing
Respond to legal letters within deadlines to avoid losing rights.
