Tenant Rights: Limits on Rent Increases Austria

Maintenance & repair duties (MRG §3) 3 min read · published September 10, 2025
Many tenants in Austria face the question of how far landlords may enforce rent increases. This text explains in plain language what "legal limits" mean, which rights tenants have and what practical steps are possible if a proposed increase is unclear or excessive. We refer to the Tenancy Law (MRG)[1] and show how documentation, deadlines and formal objections can help. The aim is to make clear to you as a tenant when to react, which documents are important and how proceedings before the district court can proceed, without legal jargon and with concrete steps.

Brief explanation: Legal limits on increases

"Legal limits" are the legal boundaries that prevent landlords from demanding arbitrarily high rent. In Austria, the Tenancy Law regulates which increases are permissible, how they must be justified and which deadlines must be observed. A written justification or a contractually agreed index model may be required; without a formal basis an increase is often contestable.

In many cases legal rules protect tenants from arbitrary increases.

First steps when an increase arrives

  • Collect all relevant documents: lease, notices, e-mails and written increase announcements.
  • Check the lease for index clauses or agreed steps and request a written justification if none is provided.
  • Pay attention to deadlines: formal objections or responses often must be filed within a short time.
  • Only pay amounts you clearly owe; mark payments as "under protest" if needed and document transfers.
Keep copies of all documents and receipts organized.

Formal objections and communication

Object to an increase in writing and briefly state your reasons (e.g. missing basis, excessive calculation). Send the objection with proof of delivery, for example by registered mail. If the matter cannot be resolved amicably, the next step is often a court review before the district court or an attempt at mediation.

Respond to legal notices within deadlines to avoid losing rights.

If it goes to court

Before the district court tenants can request a review of the increase. The court will examine whether the increase is legally justified. Collect evidence (comparable rents, apartment condition, correspondence) and prepare a clear chronology. For fees, deadlines and forms use the official portals or seek legal advice.
