As a tenant in Germany you should know which documents and deadlines apply to the smoke alarm obligation and how to prove compliance.

I show how to report defects, which legal bases apply here and what local courts consider in disputes.

The information refers to nationwide rules and references to state building codes in Germany and helps families meet deadlines reliably. Read on for practical checklists and official sources.

Smoke alarm obligation explained

In many federal states, smoke alarms in living rooms are mandatory; the exact design is set out in the respective state building codes. For tenants this means: smoke alarms must be present, functional and regularly maintained. In tenancy law, obligations from the German Civil Code (BGB) play a role, for example regarding maintenance and defect remediation[1]. In disputes over responsibilities, the local court (Amtsgericht) often decides as the first instance[2].

Keep all invoices, maintenance records and photos in one place.

Which documents do tenants and families need?

  • Written notice from the landlord about installation or maintenance (installation proof).
  • Maintenance or inspection records with date, company and inspection note.
  • Photos of the smoke detector showing installation date or serial number.
  • Template letter to the landlord when replacement or maintenance is required.
Documentation increases your chances of success in disputes.

Important deadlines and timelines

Deadlines arise from the tenancy agreement, maintenance contracts or manufacturer instructions. Act promptly if smoke detectors fail or are missing: report the defect in writing and set a reasonable deadline for remediation (e.g. 14 days). If there is no response, document again with photos and only consider legal action after legal advice.

Set deadlines clearly and in writing to avoid losing rights later.

How to report defects correctly

  • Send a formal defect notice to the landlord with description, date and photo.
  • Name a deadline for remediation (e.g. 14 days) and include proof of receipt.
  • Keep all replies, delivery notes and contractor invoices.
A written, verifiable defect notice is often decisive in legal disputes.
