Subletting, flat-sharing & co-tenancy 2 min read · published September 10, 2025

As a tenant in Austria, subletting, shared flats (WGs) and co-tenancy are often practical options, but they also raise legal questions. This text explains clearly when subletting is allowed, which obligations arise from a lease and how tenants can enforce their rights in case of defects, repairs or unlawful notices of termination. You will receive clear guidance on notifications, deadlines, documentation and conduct during viewings or handovers. The aim is to empower tenants to resolve conflicts where possible without court action and, if necessary, to proceed legally or with authorities. Many tips are practical and tailored to the Austrian legal situation. This guide also shows how to gather evidence and observe deadlines.

What is subletting, shared flats and co-tenancy?

Subletting means that a primary tenant temporarily hands over part or all of the apartment to another person. In a shared flat (WG) several people share an apartment and often the rent contract. Co-tenancy describes situations where multiple people act as joint tenants. The legal basis depends on your lease and the Mietrechtsgesetz (MRG)[1].

Sublease agreements should be put in writing to avoid misunderstandings.

Rights and obligations

As a subtenant or WG member you have duties and rights towards the primary tenant and often also towards the landlord. Key points include:

  • Pay rent on time and comply with agreements.
  • Report defects and request necessary repairs.
  • Observe notice periods and deadlines for defect notifications.
  • Notify about subletting and check whether consent is required by the main lease.
  • Respect privacy: access to the apartment only by agreement.
Keep all rent receipts and communications organized and accessible.

Termination, defects and legal steps

If there is a dispute about rent, repairs or termination, first communicate in writing and respect deadlines. Record phone calls, take photos and collect evidence. For serious issues a court-based resolution may be necessary; district courts handle tenancy disputes and forms and procedures are available via judicial services[2].

Respond promptly to formal notices, otherwise rights may lapse.
