Challenge Rent in Austria: Tenant Appeal

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

As a tenant in Austria, you can challenge the reasonable rent if a rent increase or the category rent seems unreasonable. This text explains in plain language which steps to consider when filing an appeal or complaint: deadlines, required evidence, formal requirements and where to submit a procedure (district court). You will learn how to gather documents, prepare a written statement and when legal assistance makes sense. The goal is for you to understand your rights, respond in a dispute and assess realistic chances. Legal bases such as the Tenancy Law (MRG)[1] and procedural paths via JustizOnline are briefly mentioned so you can act purposefully.

What does "reasonable rent" mean?

The reasonable rent is determined by legal provisions and prevailing market rents. It is crucial whether the requested rent corresponds to the category and condition of the apartment. If in doubt, tenants should examine the calculation and request a detailed justification from the landlord.

In many cases, a comparison with similar apartments helps to assess the rent.

When can tenants file an appeal?

Tenants can file an appeal if the rent increase is formally incorrect, the calculation is not transparent, or the rent is significantly above the market. Pay attention to statutory deadlines and forms of service; an incorrectly served increase can be contestable.

Respond within the stated deadlines, otherwise you may lose rights.

Practical steps

  1. Collect documents: lease, correspondence, photos of condition and features (evidence).
  2. Check deadlines: when was the increase served and by when is an appeal possible (deadline).
  3. Draft a written appeal: date, reasons, requested correction and signature (form).
  4. Initiate proceedings: if no agreement, sue at the district court or file a complaint (court).
  5. Seek advice: contact tenant associations or legal representation if the matter is complex (contact).
Accurate documentation and clear deadlines increase your chances of success in appeals.

Formal requirements and evidence

The appeal should be factual, complete and timely. Evidence such as old leases, payment receipts and comparison offers are central. Note inspection dates and any verbal agreements in writing.

FAQ

How much time do I have to file an appeal?
The deadline depends on the service of the rent increase; check the notice carefully and act quickly because deadlines can be short.
Which authority decides disputes?
Generally, the competent district court decides; if remedies are possible the case may be taken further.
Do I need a lawyer?
For simple cases tenant advice is often sufficient; for complex tenancy law issues legal representation is recommended.

How-To

  1. Gather all relevant documents and evidence (evidence).
  2. Check service and appeal deadlines (deadline).
  3. Write a clear, dated appeal with reasons and evidence and send it with proof of delivery.
  4. If necessary, file a lawsuit at the district court and present your evidence (court).
