Rent Reduction and Tenant Rights in Austria

Tenant rights & basic protections (MRG) 2 min read · published September 10, 2025
As a tenant in Austria, you can reduce the rent if your apartment has defects that affect living quality. This text explains step by step when a rent reduction is justified, how to document defects correctly, which deadlines and forms to observe, and how to communicate with the landlord. I describe practical steps for securing evidence, tips for keeping deadlines and indications when advice from the tenants' association or a court is useful. You will also learn how rent reduction is calculated, the role of written form and photos, and which authorities in Austria can assist. For complex cases I show how going to the district court or reviewing Supreme Court decisions can help.

When You Can Reduce Rent

A rent reduction is possible when the usability of your apartment is significantly restricted. Relevant are law and case law, in particular the Mietrechtsgesetz (MRG).[1] A reduction claim must be well justified and documented.
Keep copies of all communications and photos stored safely.

Common Defects and Examples

  • Heating failure or insufficient heating performance
  • Mold infestation in living areas
  • Water leaks or broken sanitary facilities
  • Severe noise disturbance due to construction defects

How to Prove and Document Defects

  • Take photos as evidence
  • Note the date and time of each observation
  • Record witnesses by name
  • Keep written notices to the landlord

Notifying the Landlord

Report defects always in a verifiable way and preferably in writing. Describe the defect clearly, attach photos and set a reasonable deadline for remedy.
  • Notify in writing and verifiably
  • Set a reasonable deadline for remedy
  • Consider legal steps if repairs are refused
Respond to deadlines and requests promptly, otherwise you may lose your claims.

FAQ

Can I reduce the rent immediately?
In many cases yes, but the reduction must be properly justified and documented; inform the landlord in writing.
How much can the rent be reduced?
The amount depends on the extent of the impairment and is often set as a percentage; in disputes the court decides.
What if the landlord does not respond?
Set a deadline, seek advice from a tenants' association or involve a district court.[2]

How-To

  1. Document defects photographically and in writing
  2. Inform the landlord formally by registered mail or email
  3. Name a reasonable deadline for remedy (e.g. 14 days)
  4. Calculate and announce the rent reduction
  5. In case of dispute: collect documents and, if necessary, involve the district court

Key Takeaways

  • Good documentation protects your claims.
  • Observe deadlines strictly.
  • If in doubt, seek legal advice.
