What to collect

The following documents help you prove the damage and enforce your rights:

  • Written defect notice to the landlord
  • Photos of thermometers and affected rooms with dates
  • Temperature records or heating logs
  • Communication: emails, SMS and letters
  • Receipts for emergency service, replacement heaters or repairs
  • Witness statements from neighbors or property manager
Keep receipts and photos organized.

How to proceed

Rights and obligations are governed by the Mietrechtsgesetz (MRG)[1], so it is important to observe deadlines and formal requirements.

  1. Inform the landlord immediately in writing about the heating failure and demand remediation within a reasonable deadline.
  2. Document temperatures, date and time and all contacts with the landlord.
  3. Request a written confirmation from the landlord about receipt and planned measures.
  4. If necessary, hire an emergency heating service and keep invoices as evidence.
  5. Consider rent reduction only after legal review; note calculation basis and period.
  6. If no response, use official forms or legal steps via the JustizOnline platform[2].
Respond to written notices within deadlines to preserve your rights.

FAQ

Which proofs suffice as temperature evidence?
Photos showing a visible thermometer, daily temperature records or a heating service log are suitable.

Contact the landlord first, then the property manager if applicable, and if necessary the district authority or court to enforce claims.
