Tenant Help: Heating & Hot Water in Austria

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

If the heating or hot water in your rented flat fails, swift action is important. As a tenant in Austria you have rights to basic habitability and the landlord is generally obliged to remedy defects.[1] This guide explains in plain language how to report faults, which deadlines apply, how to secure evidence and when to consider further steps such as substitution measures or legal action. It is aimed at tenants without legal expertise and shows practical wording for notifications to the landlord, tips for communication and which documents to have ready for authorities or courts. Use the checklist and the step‑by‑step instructions to reach a solution quickly.

Immediate steps and your rights

When heating or hot water fails, act clearly and with documentation. Inform the landlord and property management immediately, state the scope of the problem and set a concrete deadline for remedy. If there is a health risk, point this out explicitly and demand immediate remedy.

  • Inform the landlord or property management immediately by phone and in writing.
  • Document the damage: take photos, note date and time and record affected rooms.
  • Set deadlines: state a clear deadline (e.g. 48–72 hours) and announce it in writing.
  • Demand repair in writing and keep proof of communication.
  • If there is no response: consider options such as substitution measures or legal action at the district court.
Thorough documentation increases your chances of success in complaints.

Photographs, short written chronologies and witness statements are valuable if substitution measures or rent reduction become necessary later. Also keep heating cost statements if the problem persists.

What to use for communication

Write a short, factual notification with date, description of the defect and a deadline for remedy. Send this preferably by e‑mail and additionally by registered mail if nothing happens within the deadline. Note down call notes with date and time.

Respond to legal requirements promptly to avoid disadvantages.
