Subletting in Austria: Tenant Rights & Consent

Lease types (fixed/indefinite, main/sublet) 2 min read · published September 10, 2025

When is subletting allowed?

Subletting is generally possible if the lease or the Tenancy Act (MRG) does not explicitly prohibit it and the primary tenant obtains the landlord's permission. In many cases the contract or law requires consent in writing or compliance with certain conditions.[1] Subletting can be time-limited or for individual rooms; it is important that the use does not constitute a breach of the lease.

Subletting must often match the intended use of the lease.

Landlord consent

When asking the landlord, tenants should provide clear and complete information. A written request increases legal certainty and documents the process.

  • Period of sublet (from/to, exact dates)
  • Proposed sublet rent and arrangement for utilities
  • Details about the subtenant and proofs (ID, employment status)
Send the request in writing and keep a copy for your records.

Reasons and limits for refusal

The landlord may refuse consent for important reasons: overcrowding, endangering the property, unreasonable nuisance, or if the sublet violates mandatory regulations. A blanket refusal without justification is often contestable.

  • Safety risks or legal prohibitions
  • Risk of overcrowding or change of housing use
  • Unreasonable disturbance to the community
If the landlord unjustifiably refuses, document the correspondence and seek advice.

Practical steps for tenants

Proceed in a structured way to avoid conflicts: check the lease, prepare a complete request and collect documents for the subletting. If necessary, obtain legal advice early.

  • Check deadlines and submit the written request in time
  • Send a written request including all relevant details
  • Gather proofs such as ID, proof of employment and payment receipts
  • Contact advisory services or legal counsel if unsure
Detailed documentation increases your chances of success in disputes.
