Tenant Rights in Austria: Report Changes

Tenant rights & basic protections (MRG) 2 min read · published September 10, 2025
As a tenant in Austria, it is important to report changes in your housing situation in time so your rights remain protected. Whether it concerns a new primary tenant, a change in household size, a permanent sublet or new contact details: deadlines and formalities vary depending on the contract and legal basis. This guide explains clearly and practically when to report which information to the landlord or to authorities such as the district court, which documents are useful and how to protect yourself from disadvantages. The aim is to give tenants understandable steps so reports are made correctly and disputes are avoided. Where necessary we cite relevant passages of the Mietrechtsgesetz (MRG) and show how to find free advice and the correct forms.

When to report changes?

Many changes affect rights and obligations in the tenancy. Report changes early, especially if the contract contains reporting rules or the Mietrechtsgesetz (MRG) applies.[1]

  • Change household size (people move in/out).
  • Register a new sublet (subtenant).
  • Report a rent increase (rent) and clarify supporting documents.
  • Report important repairs (repair) and observe deadlines.
  • Change contact details or bank information.
Respond to legal letters within deadlines to avoid disadvantages.

Which deadlines apply?

Deadlines may be set in the lease or by law. For deadline-bound changes always check the exact deadline and the form of notification (written, registered mail).

Keep confirmations and receipts for at least two years.

Documentation and securing evidence

Collect receipts, photos and correspondence before you report changes or respond to inquiries.

  • Photos of damage and receipts as evidence (evidence).
  • Keep written notifications and acknowledgements of receipt.
  • Note contact details of witnesses or housemates.

FAQ

A rent increase is only effective if it is contractually or legally permissible; check the reasons and deadlines.
Which documents do I need for authorities or court?
Usually the lease, correspondence with the landlord, payment receipts and photos as evidence.
