Tenant Rights: Challenging Rent Increases in Austria

Rent & increases (reference rent, categories, form) 2 min read · published September 10, 2025
As a tenant in Austria you may wonder whether a landlord may have a rent increase reviewed and how you should respond. This guide explains in plain language what steps landlords and tenants can legally take, which deadlines and formal requirements apply and which documents you should collect. You will learn when a review is permissible, how rent categories or reference rents can matter and how a court clarification at the district court proceeds. The aim is to empower you as a tenant to represent your rights calmly and factually, meet deadlines and prepare necessary documents so you can act well informed in a dispute over a rent increase in Austria.

What rights do tenants have?

As a tenant you are generally entitled to transparency: any notice of a rent increase must be reasonably justified. Check whether the increase was formally served correctly and whether the stated reasons (e.g. adjustment to reference rent or category) are documented.

Tenants are entitled to clear justifications for rent increases.

When may a landlord have a rent increase reviewed?

A review may be permissible if the landlord cites a contractual or statutory basis; the Mietrechtsgesetz (MRG) and court competence are decisive.[1] Often deadlines and formal requirements must be observed before a judicial clarification is possible.

What steps should tenants take now?

  • Check the landlord's letter and note any deadlines.
  • Collect the lease, payment records, photos and correspondence as evidence.
  • Contact legal advice or your tenant protection organisation early.
  • If necessary: have a lawsuit or application prepared at the district court.[2]
Good documentation increases your chances in disputes.
