Do you need council approval for a duplex or dual-occupancy project in Sunshine Coast?
Whether a duplex or dual-occupancy project in Sunshine Coast needs a development application is decided by Sunshine Coast Planning Scheme 2014, Version 27, which places each proposal in one of the three Planning Act 2016 categories: accepted development, code assessable or impact assessable. For a Sunshine Coast lot the answer turns on the zone, any precinct mapped over it and the overlays that apply, so Sunshine Coast council does not publish one blanket answer for duplex and dual-occupancy proposals.
Casa's rules register for Sunshine Coast Planning Scheme 2014 records dual occupancy as a contemplated use in 4 of the 13 Sunshine Coast zones it tracks, code assessable in Emerging Community, High Density Residential, Low Density Residential and Medium Density Residential. In the 9 remaining Sunshine Coast zones a dual occupancy is not an anticipated use, which in practice means impact assessment or an unlikely approval.
Minimum lot sizes and frontages for a Sunshine Coast dual occupancy are set per zone and often per precinct, and the register figures for those minimums have not yet been checked against the scheme text, so this page quotes Sunshine Coast's own wording below rather than printing an unchecked number.
The Sunshine Coast record gives a feel for what assessment involves: a quarter of the 1,755 dated duplex and dual-occupancy decisions were made within 26 days of lodgement, and a quarter took longer than 92 days.
The zone, precinct and overlay position of one Sunshine Coast address is what settles the pathway for a duplex or dual-occupancy project, and a free Casa block check reads all three for any Sunshine Coast lot in seconds.
What Sunshine Coast’s scheme says about duplex and dual-occupancy development
The passage below is quoted word for word from Sunshine Coast Planning Scheme 2014, Version 27, the instrument Sunshine Coast council assesses duplex and dual-occupancy proposals against, from the Dual occupancy code, as Casa held the Sunshine Coast scheme text on 9 Sept 2026.
“The purpose of the Dual occupancy code is to ensure dual occupancies are appropriately located, achieve a high level of comfort and amenity for occupants, maintain the amenity of neighbouring premises and are compatible with the character and streetscape of the local area.”

Duplex position by zone in Sunshine Coast
Casa's register holds 13 Sunshine Coast zone rows relevant to a duplex or dual-occupancy project, each citing Sunshine Coast Planning Scheme 2014, and precinct mapping and overlays tighten these duplex and dual-occupancy positions for individual Sunshine Coast lots.
| Zone | Dual occupancy | Assessment |
|---|---|---|
| Emerging Community | Yes | Code assessable |
| High Density Residential | Yes | Code assessable |
| Low Density Residential | Yes | Code assessable |
| Medium Density Residential | Yes | Code assessable |
| Community Facilities | No | not held |
| High Impact Industry | No | not held |
| Limited Development (Constrained Land) | No | not held |
| Low Impact Industry | No | not held |
| Medium Impact Industry | No | not held |
| Open Space | No | not held |
| Rural Residential | No | not held |
| Rural | No | not held |
| Sport and Recreation | No | not held |
"not held" means Sunshine Coast's register has no value for that duplex and dual-occupancy cell, not that the scheme is silent. Height, setback and site-cover figures for Sunshine Coast zones are held in the register but have not been checked against the scheme text, so they are not printed on this duplex and dual-occupancy page.

Duplex in Sunshine Coast: common questions

Only your lot's zone, precinct and overlays under Sunshine Coast Planning Scheme 2014 can answer that for a duplex or dual-occupancy project at a Sunshine Coast address.

Sunshine Coast council has decided 1,764 dual-occupancy and duplex applications in our records, so the pathway question comes up constantly in Sunshine Coast.

Casa's register for Sunshine Coast Planning Scheme 2014 records duplex and dual-occupancy development as contemplated in Emerging Community, High Density Residential, Low Density Residential and Medium Density Residential, 4 of the 13 Sunshine Coast zones tracked.
