Deadlines for Mediation Requests – Tenants Austria

Dispute resolution (incl. rent reduction) 2 min read · published September 10, 2025

As a tenant in Austria, it is important to know the deadlines for applications to a mediation body. Whether it concerns rent reductions, repairs or termination disputes: deadlines often decide the success or loss of your claims. This article explains in plain language which deadlines usually apply, when you should collect evidence and how to file an application correctly. Step by step we show which documents help, how to calculate deadlines and where to find formal assistance. If you are unsure, contact an advice center or lawyer early so deadlines do not pass unnoticed.

When is an application necessary?

An application to the mediation body is useful as soon as a relevant defect, a unilateral increase or a termination occurs and communication with the landlord does not lead to a solution. Many tenancy claims are governed by specific legal frameworks such as the Mietrechtsgesetz (MRG)[1], which affect deadlines and responsibilities.

Important deadlines

Typical deadline points to watch include the response time after reporting defects, the period to claim rent reductions, and deadlines for lodging complaints. Check early whether your situation is bound to a mediation body or if a district court will be competent.

  • Deadline to report defects: report obvious defects in writing immediately so that the date of knowledge is documented.
  • Deadline for rent reduction: specify the start of the reduction if the apartment is not usable as agreed.
  • Deadline for mediation application: file the application once an agreement is not possible.
Documentation such as photos and correspondence strengthens your position in mediation.

How do I file the application?

Practically proceed as follows: gather evidence, formulate your request clearly and submit the application to the competent body. If unsure, clarify jurisdiction in advance with an advice center or the district court[2].

  1. Collect evidence: photos, emails, payment proofs and logs are helpful.
  2. Send a written defect notice to the landlord and set a deadline.
  3. Submit the application to the mediation body and attach copies of all evidence.
  4. Pay attention to scheduling notices and respond within deadlines.
Keep all original receipts stored in a single, safe place.
