Subletting, flat-sharing & co-tenancy 3 min read · published September 10, 2025

As a tenant in a shared flat or sublet in Austria, it is important to know deadlines and special rules. Whether termination periods, notifications for repairs, or rules for co-tenancy: missed deadlines can cost rights. This guide explains in clear language which deadlines apply to shared-flat residents and subtenants, how terminations must be served correctly, which evidence is helpful and what steps follow in disputes with the landlord. The information is based on Austrian tenancy law[1] and explains practical steps for tenants so you can meet deadlines, attend appointments and effectively protect your rights. Sample actions and contacts for quick help are also listed. Read on for specific deadlines, termination templates and guidance on defects or unlawful termination.

Which deadlines should I know?

Important deadlines for tenants concern terminations, also in subletting or co-tenancy, as well as deadlines for damage notifications and repair reports. Fixed-term leases often have their own durations; for open-ended contracts, statutory or contractual notice periods apply. In disputes, the district court usually decides on claims and terminations[2].

Record all deadlines immediately in a calendar and keep receipts.

Termination deadlines (overview)

  • Observe contractual or MRG statutory ordinary notice periods.
  • Check special deadlines for sublets or co-tenancy.
  • Serve a written termination and document receipt.
  • Observe deadlines for cosmetic repairs or move-out dates.
Respond quickly to terminations, otherwise you may lose rights.

Deadlines for defects and repairs

If there are defects, report them immediately. There are often short deadlines within which the landlord must respond; document the time and content of the report.

  • Report defects in writing immediately and take photos.
  • Store correspondence and appointments chronologically.
  • If not remedied: consider rent reduction or remedy at the landlord's expense.
Documentation increases the chances of success in legal disputes.

How to secure evidence and dates

Keep emails, SMS, photos and witness statements. Keep payment receipts and handover protocols. If possible, send important notifications by registered mail so you can prove deadlines and receipt.

Copies of all letters and delivery confirmations are often decisive in court.

Typical steps for missed deadlines

  1. Name the deadline and claim in writing and set a deadline.
  2. Contact the landlord to clarify and document the response.
  3. Consider court action if no solution is found (district court competent).[2]
  4. Collect all evidence and, if necessary, seek legal advice.
