FAQs on Co-Tenancies & Subletting in South Australia

Living in shared accommodations is common amongst renters in South Australia, whether through co-tenancies or subletting. The Residential Tenancies Act 1995 (SA) outlines your rights and obligations in these housing arrangements. This guide answers the most frequently asked questions about co-tenancies and subletting, helping you navigate your rental situation with confidence.

Understanding Co-Tenancies

A co-tenancy occurs when two or more people sign a lease agreement together. All tenants share equal responsibility for adhering to the lease terms and maintaining the property.

Rights and Responsibilities

  • All co-tenants are jointly liable for rent and damages, meaning if one tenant fails to pay rent, the others must cover the shortfall.
  • Changes to the lease, such as adding a new tenant, require the consent of all co-tenants and the landlord.
  • If a co-tenant wishes to leave, they must negotiate a lease transfer or request permission from the landlord to find a replacement.

Subletting in South Australia

Subletting occurs when a tenant rents part or all of the rented property to another person. This arrangement comes with its own set of rules under the Residential Tenancies Act 1995.

Key Considerations

  • You must have written consent from your landlord to sublet your property.
  • As the head-tenant, you remain responsible for the lease and ensuring the sub-tenant complies with its terms.
  • It's important to have a clear, written agreement with your sub-tenant detailing rent, utilities, and other expectations.

Forms and Processes

If you need to transfer a lease or obtain permission for subletting, you may need to use specific forms:

  • Lease Transfer Form: Use this form to apply for a lease transfer when a co-tenant leaves. You can access it from the Consumer and Business Services website.
  • Subletting Agreement: Draft a clear agreement to outline duties, responsibilities, and financial arrangements with a sub-tenant.

Handling Disputes

Disputes between tenants, sub-tenants, and landlords can be mediated by the South Australian Civil and Administrative Tribunal (SACAT). SACAT oversees residential tenancy disputes and can assist in resolving issues such as bond returns, rental payments, or property maintenance.
