Tenants in Germany: Report Gas Smell - Deadlines & Forms

Safety & Emergency Protections 3 min read · published September 07, 2025
As a tenant in Germany, smelling gas in your apartment can be alarming. This text clearly explains which documents you should have ready, which deadlines apply, and which authorities or courts you can contact. We show step by step how to report the smell safely, secure evidence and assert your rights against the landlord under Sections 535–580a of the German Civil Code (BGB)[1]. This includes advice on correct behaviour in an acute danger, which official forms may be used and how to document deadlines. The guide is aimed at families and single occupants and avoids legal jargon so you can act quickly and safely. At the end you will find sample texts for reports to landlords and emergency services and notes on possible rent reductions.

What to do if you smell gas?

If you detect a gas smell in your home, every minute counts. First check whether people are at health risk; if the smell is strong, leave the apartment immediately and call the emergency number. Then inform your gas network operator and your landlord in writing. Document smell, time and any conversations in writing or with photos to have evidence later.

If you detect a strong gas smell, leave the apartment immediately and call emergency number 112.
  • Call emergency number 112 (call) if there is acute danger
  • Call the network operator or gas supplier (call) and report the fault
  • Send a written defect notice to your landlord (Form/notice) and document receipt
  • Secure photos (photo) and evidence (evidence): record date and time

Important documents

Gather all evidence in one place: written defect notice to the landlord, confirmation of the fault report to the network operator, photos or videos of the affected area, and notes on times and witnesses. If possible, send the defect notice by registered mail or by email with read receipt.

Keep all reports, receipts and photos organized and safe.
  • Written defect notice (sample text recommended) with date and time (Form)
  • Photos and videos as evidence (photo, evidence)
  • Confirmation of the fault report from the network operator or technicians (call)
  • Receipts for any costs incurred (payment), e.g. hotel costs if evacuated

Deadlines and legal basis

Relevant deadlines and obligations for tenants and landlords are in the German Civil Code (BGB) Sections 535–580a. If deadlines are set or court action becomes necessary, the local Amtsgericht handles tenancy disputes; procedural rules are in the Code of Civil Procedure (ZPO). In an emergency: act immediately, document deadlines and landlord responses and send formal letters in a verifiable way.[2]

Good documentation makes later claims or a rent reduction easier to prove.

Practical templates and forms

There is no nationwide compulsory form for a defect notice about gas smell; typically a simple written letter with date, time, description and request for remedy suffices. For court steps use the usual complaint and submission forms of your local Amtsgericht. Example template: "Written defect notice: Gas smell in apartment" asking for immediate remedy and setting a deadline.

State date, time and your request for immediate remediation clearly.
