Heating/Hot Water: Tenants' Rights in Austria

Maintenance & repair duties (MRG §3) 2 min read · published September 10, 2025

What to do if the heating or hot water fails?

A failure of the heating or hot water affects the usability of the apartment. Austrian tenancy law sets basic standards; the Mietrechtsgesetz (MRG) regulates many landlord obligations.[1] Reports should always be made in writing, with the date and a precise description of the defect. At the end of this guide you will find information on official forms and online services.[2]

  • Report in writing (notice) to the landlord: include date, time, affected rooms and attach photos.
  • In case of acute danger or health risk, hire a professional immediately (repair) and document the costs.
  • Secure evidence: collect photos, videos, messages and invoices (evidence).
  • Observe deadlines: give the landlord a reasonable period to remedy the defect and document this (deadline).
Keep all reports and invoices safely stored.

If the landlord does not act in time, a rent reduction (Mietminderung) can be considered or you may arrange repairs yourself and claim costs back. Check the legal situation in advance and inform yourself about permissible reduction rates.[3]

Respond quickly if there are possible health hazards and inform the landlord immediately.

What are the landlord's obligations?

The landlord is obliged to keep the apartment in a habitable condition and to remedy defects in a timely manner. Small repairs can be contractually regulated; larger defects usually fall under the landlord's responsibility. Necessary interventions by tradespeople must be announced in advance, except in emergencies.

FAQ
