Rent Reduction Deadlines for Tenants in Austria

Rent & increases (reference rent, categories, form) 2 min read · published September 10, 2025

As a tenant in Austria it is important to know how long you have to claim a rent reduction due to defects. This concerns, for example, heating failure, mold or water damage. In this text we explain clearly which deadlines apply, how to report defects correctly and which evidence is useful. We describe the practical process for when you may reduce rent, which steps are recommended toward the landlord and when legal action may become necessary. The information is based on Austrian tenancy law and helps you meet deadlines and enforce your rights as a tenant without taking unnecessary risks.

Deadlines and Legal Framework

Under tenancy law, defects should be reported and documented immediately. There is no single uniform deadline for all defects, so it is important to set a reasonable deadline toward the landlord. In many cases a written request with a clear deadline is sufficient; in serious defects an immediate response may be required.[1][2]

Practical Steps

  • Document the defect with photos and in writing.
  • Inform the landlord in writing and request repair.
  • Set a reasonable deadline for repair and state the date clearly.
  • If nothing happens, consider a proportional rent reduction after the deadline.
  • Consider court resolution if there is a dispute (district court, appeals process applies).
Keep copies of all letters and photos.

Evidence Collection

Careful evidence increases chances of success: dated photos, witnesses, written emails and call logs are helpful. Also note when the defect first occurred and what impact it has on habitability.

Accurate timestamps help with proving your case.

FAQ

How do I set a deadline for repair?
Write a short, clear request with a deadline date by email or registered mail; document delivery and state the reason for the deadline.
Do I have to reduce rent immediately?
Only if the defect substantially reduces habitability and a reasonable deadline for repair has failed, is a rent reduction justified.
What deadlines apply in court?
Disputes go through the district court; exact procedural deadlines are governed by the ZPO and procedural rules and should be checked with legal advice.[2]

How-To

  1. Document the defect: take photos, note dates and impacts.
  2. Notify the landlord: send a written request with a clear deadline.
  3. Set the deadline: state a reasonable deadline and announce when rent reduction will start.
  4. Reduce rent: proportionally from the end of the set deadline if no improvement occurs.
