Dual occupancy rules in Gold Coast
Building a dual occupancy in Gold Coast? City of Gold Coast applies the Queensland planning framework. Here's what that means locally — plus the overlays worth checking on your specific block.
Set entirely by your council planning scheme and zone
It depends on your council. Queensland has no statewide dual occupancy rule - each local government planning scheme decides which zones allow a duplex, what minimum lot size and frontage apply, and whether it is accepted, code assessable or impact assessable development.
Key rules at a glance
| Minimum lot size | Set by your planning scheme. Commonly 400-800 m² (indicative - varies by council and zone). Brisbane and Rockhampton both moved to 400 m² in their low-medium density residential zones. |
| Minimum frontage | Commonly 12-20 m (indicative - varies by scheme). Some schemes only treat a dual occupancy as accepted development at 20 m frontage or more. |
| Zones permitted | Typically the low-medium density residential and medium density residential zones, and in some schemes the character residential zone. Low density residential zones sometimes allow it, usually at a higher minimum lot size. |
| Approval pathway | Accepted, code assessable or impact assessable, depending on the scheme, the zone and whether the acceptable outcomes are met. |
| Can it be subdivided or strata titled? | Usually yes, through a separate reconfiguring a lot application for Torrens titles, or a community titles scheme for strata-style lots. Each resulting lot must meet the scheme's minimum lot size for subdivision, which is often larger than the minimum for building the duplex. |
| Typical timeframe | Around 2-4 months for a code assessable application; longer where it is impact assessable and publicly notified. |
Heritage, flood and bushfire controls on your specific lot can remove the fast-track and require a full application — even when the general rules say you're fine.
