Documenting Smoke Alarm Law for Tenants in Germany

Safety & Emergency Protections 3 min read · published September 07, 2025

As a tenant in Germany, it is important to properly document compliance with the smoke alarm obligation. A complete documentation helps to prove duties from the rental agreement and the BGB, avoid disputes with the landlord and have better chances in court. In this article you will learn which proofs are useful, how to practically use forms and deadlines and which authorities or courts are responsible. The guidance is practical and written in plain language so you can take concrete steps quickly, even if you have no legal training.

Why documentation matters

Smoke alarms are a safety standard; their existence and function often need to be proven, for example in damage cases or when landlords claim maintenance. Good documentation shows when you were informed or when a fault occurred and reduces points of contention.

A thorough documentation increases your chances of success in court.

Which proofs to collect?

  • Photos and videos of installed smoke alarms (evidence) with date and time, ideally immediately after moving in or after maintenance.
  • Written communications or emails from the landlord about installation, maintenance or replacement (form, notice).
  • Protocols or appointments for maintenance and inspections (within 30 days) including the company name.
  • Notes of personal conversations with date, time and contact person (call for help).
Keep original files and backups for at least two years.

Rights, duties and official foundations

The duties around rental housing and safety are regulated in the BGB; rules relevant for tenants can be found in §§ 535–580a of the BGB[1]. Procedural questions in court disputes are governed by the Civil Procedure Code (ZPO)[2]. The local court (Amtsgericht) is usually responsible for initial tenancy disputes; for precedent-based issues the Federal Court of Justice (BGH) may be relevant[3].

In many federal states, apartments must be equipped with smoke alarms.

Forms and sample letters

Use official or standardized templates for notifications and deadline letters. A common model is a written defect notice or a request letter (or a termination letter pattern if necessary) with a deadline to the landlord; official guidance is available from ministries and justice portals[4]. Example: write briefly, factually and set a clear deadline of e.g. 14 days to confirm installation or to carry out repairs.

Phrase defect notices factually and document the dispatch.

What to do if the landlord does not respond?

If the landlord does not respond to your defect notice, the following steps are advisable:

  • Send a second written request with a deadline and ask for proof (form, evidence).
  • If safety is at risk, document the danger and, if necessary, commission a qualified company with an invoice.
  • If there is no reaction, consider civil legal steps at the local court (court) or seek legal advice.
