What does a reasonable rent mean?

A reasonable rent in Austria is often based on contractual agreements and legal rules; the Mietrechtsgesetz (MRG)[1] often serves as a basis, and operating and heating costs should be considered separately. It is important that tenants can understand the composition of the rent and that increases are formally justified and properly served.

Deviating rules may apply in new buildings.

How is rent calculated for new builds?

For new-build apartments, the initial rent, agreed index clauses or market-based agreements can play a role. Operating and consumption costs are often shown separately.

  • Check operating costs and rent separately.
  • Understand contract clauses such as indexation or graduated rents.
  • Collect evidence: invoices, handover reports and correspondence.
Documentation and correspondence help to prove rent increases.

What to do about unlawful rent increases or defects?

If you notice a rent increase or defects, document everything in writing and give the landlord a deadline to remedy the issue. Only then are further steps possible.

  • Report defects in writing and set a reasonable deadline for remedy.
  • Collect photos, correspondence and receipts as evidence.
  • If the landlord remains inactive, consider filing a claim with the district court or seeking expedited legal assistance.
Respond within deadlines to avoid losing rights.

Key Takeaways

  • Collect all documents and evidence immediately when changes occur.
  • Always communicate changes in writing and request explanations.
  • Seek early support from tenant protection offices or official bodies.
