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

As a tenant in Austria, you should carefully check documents for a rent increase before agreeing. Many letters look formally correct but contain calculation errors, missing justifications or inaccurate comparative figures. This guide clearly explains which documents matter, for example the lease, the latest operating cost statement, receipts for renovations and the written justification of the increase, as well as which deadlines you must observe. I show how to collect evidence, formally object and, if necessary, contact authorities or the court. The goal is that you make safer decisions and preserve your rights as a tenant in Austria without legal expertise.

Which documents to check?

  • Lease agreement and any supplementary agreements.
  • Latest operating cost statement and bank statements showing rent payments.
  • Written notice of the rent increase with a transparent calculation.
