Secondary dwellings provide an efficient and cost-effective form of infill development on established detached house sites. Secondary dwellings can be free standing or attached to the main house and up to 65m2 in size.
An approved self-contained flat or studio, either attached to the house or somewhere else on the site is considered a Secondary Dwelling.
Building and plumbing approvals are necessary for a secondary dwelling. Infrastructure charges are no longer payable and, unless triggered by a planning scheme overlay, no planning approval is necessary.
It’s not essential, but generally recommended that tenant(s) enter into a residential tenancy agreement, so both parties are protected by the Act.
A Secondary Dwelling cannot be subdivided and remains on the same title and ownership of the main dwelling house. There are legal avenues to sell part of a property and become tenants in common, however financial and legal advice should be sought in considering this option.
Council has a factsheet specifically on the rules around secondary dwellings and what sets them apart from a duplex (Refer to Fact Sheet No. 3).
