What tenants need to know

Fundamentally, the contractual situation in tenancy law in Austria is governed by the Mietrechtsgesetz (MRG) and the respective contractual agreements. The legal framework determines the minimum requirements for heating and hot water and in which cases the landlord is responsible[1]. Key points include who bears the operating costs, how bills should be checked and which deadlines apply for defect reports.

In most cases landlords are responsible for basic heating function.

Heating, hot water: common problems

  • Heating failure: no or insufficient heat in living rooms.
  • Unclear billing: operating or fuel costs appear too high or wrongly allocated.
  • Poor documentation: missing meter readings, photos or invoices.
  • Unannounced entry to the apartment for maintenance without consent.
  • Delayed landlord response to defect reports.
Keep all receipts and photos stored safely.

How to report defects

A formal defect report helps to meet deadlines and avoid later disputes. Describe the defect precisely, state the date, attach photos and meter readings, and request a concrete deadline for repair. Send the notice in a verifiable manner, for example by registered mail or by email with a read receipt.

Respond in writing and keep track of deadlines.

How-To: Report a heating fault

  1. Collect evidence: photos, meter readings, date and time of the failure.
  2. Write a formal defect notice to the landlord and send it in a verifiable way.
  3. Set a reasonable deadline for repair (e.g. 7–14 days, depending on severity).
  4. No response? Consider involving the district court or seeking legal advice.
Thorough documentation increases your chances of success in disputes.
