Affordable living opportunities are a strong focus of our City Plan. To provide our residents with a variety of housing choices, City of Gold Coast has made it easier and more affordable to develop different types of living options. A dual occupancy is just one of the many residential choices to cater for our growing population.

A dual occupancy is made up of two dwellings (whether attached or unattached) on a single property. A dual occupancy is commonly known as a duplex.

Do I require a building approval?

If you are building a dwelling house you will need a building approval. Building approvals can be obtained by contacting a private certifier. Please see the private building certifier page for further information.

Do I require a development approval?

If your dual occupancy does not meet all the relevant development criteria of the City Plan, you may need to lodge a development application.

Low density residential zone

In the low density residential zone, a development application is not required when you:

  • are on a lot which:
    • is a corner lot; or
    • has access to both street and a rear access lane; or
    • is within 400 metre walking distance to a mixed use centre or specialist centre; and
  • meet the required outcomes in the dual occupancy code and any other applicable code (e.g. a zone code).

Medium and High density residential zone

In the medium and high density residential zones, a planning application is not required when you:

  • meet the required outcomes in the dual occupancy code and any other applicable codes (e.g. a zone code).

A City Plan overlay may also trigger the need for a development application. Refer to the do I need a development approval page for further information and instructions.

For further information on the required development application, please refer to the RiskSmart accepted to code assessment information on the RiskSmart development applications page.
