Do you need council approval for a duplex or dual-occupancy project in Moreton Bay?
Whether a duplex or dual-occupancy project in Moreton Bay needs a development application is decided by Moreton Bay Region Planning Scheme 2016, v7.1, which places each proposal in one of the three Planning Act 2016 categories: accepted development, code assessable or impact assessable. For a Moreton Bay lot the answer turns on the zone, any precinct mapped over it and the overlays that apply, so Moreton Bay council does not publish one blanket answer for duplex and dual-occupancy proposals.
Casa's rules register for Moreton Bay Region Planning Scheme 2016 records dual occupancy as a contemplated use in 8 of the 16 Moreton Bay zones it tracks, code assessable in Emerging Community, General Residential, High Density Residential, Low Density Residential, Medium Density Residential and 2 other zones. In the 8 remaining Moreton Bay 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 Moreton Bay 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 Moreton Bay's own wording below rather than printing an unchecked number.
The Moreton Bay record gives a feel for what assessment involves: a quarter of the 264 dated duplex and dual-occupancy decisions were made within 48 days of lodgement, and a quarter took longer than 90 days.
The zone, precinct and overlay position of one Moreton Bay address is what settles the pathway for a duplex or dual-occupancy project, and a free Casa block check reads all three for any Moreton Bay lot in seconds.
What Moreton Bay’s scheme says about duplex and dual-occupancy development
The passages below are quoted word for word from Moreton Bay Region Planning Scheme 2016, v7.1, the instrument Moreton Bay council assesses duplex and dual-occupancy proposals against, from the Schedule 1 definitions and General residential zone code, as Casa held the Moreton Bay scheme text on 9 Sept 2026.
“Dual occupancy - means a residential use of premises involving - 2 dwellings (whether attached or detached) on a single lot or 2 dwellings (whether attached or detached) on separate lots that share a common property;”
“The purpose of the code will be achieved through the following overall outcomes for the Suburban neighbourhood precinct: The suburban neighbourhood precinct consists of a primarily residential urban fabric providing predominantly low density, low rise, detached housing on a variety of lot sizes with a maximum site density of 15 dwellings per hectare or a maximum site density of 75 dwellings per hectare if complying with b.”

Casa's register holds 16 Moreton Bay zone rows relevant to a duplex or dual-occupancy project, each citing Moreton Bay Region Planning Scheme 2016, and precinct mapping and overlays tighten these duplex and dual-occupancy positions for individual Moreton Bay lots.

|---|---|---|
| Centre | Yes | not held |
| Emerging Community | Yes | Code assessable |
| General Residential | Yes | Code assessable |

"not held" means Moreton Bay'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 Moreton Bay 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.
