Backyard homes in Queensland

Locally referred to as Secondary dwelling or granny flat

Queensland allows secondary dwellings to be occupied or rented by anyone, but many design and planning requirements are determined through local council planning schemes.

Local council rules are critical

Size, setbacks, site coverage and development assessment requirements can differ between council areas.

Building approval is required

A new secondary dwelling requires building approval.

Development approval may also apply

The local council planning scheme determines whether separate development approval is required.

It remains secondary to the main home

The dwelling must be used in conjunction with and remain subordinate to the principal dwelling.

Anyone may occupy or rent it

State-wide occupancy restrictions based on family relationships have been removed.

Rental use may affect compliance

Fire separation, sound transmission and other building requirements may need additional assessment.

Also worth knowing

•There is no single Queensland-wide maximum floor area — local planning schemes differ.

What may affect your property?

State-wide rules are only the starting point. Councils, sites and titles differ, so these are checked for your specific address.

•Local government area
•Land zoning
•Planning overlays
•Lot size and dimensions
•Existing dwelling
•Title restrictions and covenants
•Bushfire, flood and environmental risk
•Setbacks and site coverage
•Utility and wastewater capacity
•Delivery and construction access
•Intended residential or non-residential use

Intended use changes the pathway

A self-contained residence, a guest room, a home office and a non-habitable studio may be treated differently. The proposed facilities and how the building will be occupied can change the applicable planning and building pathway.

Check my backyard

My Backyard Home provides general, preliminary information based on published planning and building material. It does not confirm that a dwelling or structure can be built on your property and is not legal, planning, building, engineering, financial or tax advice. Requirements may vary according to your address, council, title, zoning, overlays, site conditions, intended use and chosen product. Final feasibility, permits, approvals and compliance must be confirmed by the relevant authorities and qualified professionals.
