What is subletting?

Subletting means a tenant rents out the apartment or parts of it to a third person. Austrian tenancy law sets special duties for tenants and landlords here, such as information and consent obligations towards the landlord[1].

In Austria the Mietrechtsgesetz (MRG) regulates key questions about subletting.

When do tenants need consent?

Whether consent is required depends on the lease and statutory rules. Contract clauses can govern subletting, and tenancy law protects both tenants and landlords against arbitrary prohibitions.

  • Written request with details about the subtenant and the duration of the subletting.
  • Information on creditworthiness and the purpose of the subletting as proof.
  • Response deadlines: react promptly to follow-up questions, usually within short timeframes.
Ask for any consent in writing to avoid later misunderstandings.

Rights and limits

Landlords cannot prohibit subletting arbitrarily; refusals must be factually justified. At the same time, tenants have obligations such as consideration and payment of the agreed rent. In disputes, the district court may decide or mediation can be used[2].

Landlords may only forbid subletting within narrow limits.

FAQ

Can the landlord generally prohibit subletting?
No. A general, blanket ban is often unlawful; concrete and factual reasons are required for a prohibition to be effective.
How do I formally request permission to sublet?
In writing by email or letter with the subtenant's name, duration, agreed rent and, if applicable, proof of creditworthiness.
What can I do if the landlord refuses?
Document communication, seek discussion or mediation, and consider legal steps at the district court.

How-To

  1. Create the request: include the subtenant's name, duration and amount of the subrent.
  2. Gather documents: ID, income proofs and, if relevant, photos or inventory lists.
  3. Observe deadlines: set a reasonable reply deadline and respond promptly to follow-ups.
  4. Contact the landlord: clarify open questions directly before planning further steps.
  5. Court resolution: if necessary, proceedings at the district court can follow to enforce consent or rights.[2]
