Tenant Template: Rent Increases in Austria

Templates & model letters 3 min read · published September 10, 2025

As a tenant in Austria, you can challenge unlawful or improperly justified rent increases. This article explains in plain language which legal limits apply, which deadlines you must observe, and how a template letter can help you assert your rights in writing. You will receive practical advice on documentation, deadline management, and next steps if a dispute goes to court. The goal is to help you decide whether a conversation with the landlord is sufficient, when a formal letter is necessary, and when legal action may be appropriate. The guidance is based on the Mietrechtsgesetz and typical procedural practice in Austria.[1]

When is a rent increase legally restricted?

In Austria, the Mietrechtsgesetz (MRG) sets out the conditions under which landlords may raise rent. Not every announced increase is lawful: reasons, formal requirements and deadlines must be observed. First check your lease and the landlord's exact justification. If the justification is unclear or there are formal errors, the increase is often contestable.

Keep all letters and receipts organized and stored safely.

Typical limitations

  • Deadlines and dates must be specified clearly by the landlord
  • Increases must not arbitrarily raise the rent payment
  • Formal errors in the justification are a common point of attack

How to respond with a template letter

A clearly worded, factual template letter can help protect your position: request a precise justification, set a deadline for a reply, and state that you will review evidence or consider legal steps. Send the letter by registered mail to have proof of delivery. Attach copies of relevant documents and note the date and content of all conversations with the landlord.

Do not respond emotionally; document facts and deadlines instead.

Example content for the template letter

  • Request a written and transparent justification for the increase
  • Set a deadline for reply (e.g. 14 days)
  • Announce that missing information will be grounds for legal review

If no convincing answer is received within the set deadline, consider asking for a judicial review. District courts are usually competent; legal recourse may be necessary for contract interpretation or to assert formal errors.[2]

Formal defects in the justification are decisive in most cases.
