Subletting Deadlines for Tenants in Austria

Lease types (fixed/indefinite, main/sublet) 3 min read · published September 10, 2025

As a tenant in Austria you may often wonder which deadlines and rules apply to subletting and whether you need the landlord's consent. This article explains clearly which time requirements for requests, responses and objections matter, how long you should wait for consent and what steps you as a tenant can take if the landlord does not respond or unlawfully refuses consent. I outline practical deadlines, what to pay attention to in letters and how to document evidence safely so you can better assert your rights before the district court or in negotiations. The language is intentionally simple and understandable for tenants without a legal background.

What applies to deadlines for subletting?

Fundamentally, tenancy law determines whether and when landlord consent for subletting is required; the tenancy agreement often demands the landlord's consent. According to the Mietrechtsgesetz (MRG) and general tenancy principles, tenants should submit requests in writing and give the landlord sufficient time to decide. If a time limit is named by law or contract, it is binding; if no specific deadline exists, reasonable deadlines apply depending on the case.[1]

Keep all requests and responses in writing.
  • Consent deadline: Contractual deadlines must be observed; without agreement a timely response is recommended.
  • Form and proof: Submit your request in writing and, if possible, request confirmation of receipt or send by registered mail.
  • Documentation: Photos, messages and emails help in later disputes.

How to act if the landlord does not consent?

If the landlord does not reply within a reasonable period or refuses consent, first check operating cost rules, house rules and contractual clauses. A formal request is often sensible before objection or lawsuit. In case of unlawful refusal, tenants can assert injunctions or consent in court.

Respond in writing and observe deadlines to avoid losing rights.

Practical steps for tenants

  • Written request: State purpose, duration and identity of the subtenant clearly and include contact information.
  • Set a deadline: Give a reasonable deadline for a reply, e.g. 14 days, and document this deadline.
  • Collect evidence: Keep copies of messages, signed agreements and photos.
  • Court action: If necessary, consider filing at the district court or seek legal advice.[2]

What tenants should pay special attention to

Watch for clauses in the lease about maximum occupancy and potential additional costs. Clarify unclear clauses before accepting a subtenant. Inform the subtenant about house rules and possible extra costs. If repairs or defects occur, they are handled separately and do not directly change the consent obligation.

Clear agreements with the subtenant prevent later conflicts.
