Rent & increases (reference rent, categories, form) 3 min read · published September 10, 2025

Many tenants in Austria experience temporary heating or hot water outages, especially in transition seasons or due to technical faults. As a tenant you have legal rights, such as the landlords obligation to remedy defects and possibly rent reduction or damages. This article explains when an interruption qualifies as a defect, what obligations the landlord has, how to report disturbances correctly and which deadlines and court steps are possible. Documentation, photos and deadlines are important; also inform yourself about the Tenancy Act[1] and court procedures at the district court[2]. Below you will find practical steps, sample wordings and answers to frequent questions.

When is an interruption considered a defect?

An interruption is a defect if the agreed or usual fitness for use of the rented property is impaired. A complete failure of heating during the heating season or lack of hot water that significantly restricts the use of the apartment usually constitutes a defect. The assessment depends on the extent, duration and season.

In many cases, failure of heating or hot water justifies a rent reduction.

What should you do as a tenant?

  • Report in writing: Inform the landlord immediately in writing (email or registered mail) and describe the defect precisely.
  • Document: Take photos, note dates and duration of the disturbance and possible consequences.
  • Set a deadline: Give a reasonable deadline for repair and announce possible legal consequences.
  • Check rent: Inform yourself about possible rent reduction and calculate your claim.
  • In case of acute danger: Contact emergency services or the competent authorities immediately and document all steps.

Landlord rights and obligations

The landlord is obliged to keep the rental property in a usable condition and must remedy defects without delay. Minor repairs can be contractually regulated differently, but major defects are the landlords responsibility. If the landlord does not act, you as a tenant have various legal remedies, from rent reduction to remedy by third parties.

Respond in writing and keep deadlines in view to avoid losing your rights.

Deadlines and legal remedies

Set a clear deadline for the landlord to remedy the defect. If there is no response, you can consider measures such as rent reduction, involving a mediation body or suing at the district court. For legal steps it is useful to present evidence and communications in an orderly manner.[2]
