Opportunity types

Dual occupancy opportunities in South-East Queensland.

Dual occupancy is the most-mistaken opportunity type in SEQ — half the listings advertised as 'duplex potential' won't carry one once you read the planning scheme honestly. Casa Daily scores every fresh REA listing for genuine dual-occupancy and duplex potential against the council's specific dual-occupancy code, the lot's actual geometry, and the binding overlay profile. The ones that survive land in your morning brief.

What we mean by 'dual occupancy'

Two dwellings of equal status on a single lot — duplex pair (attached), side-by-side detached, or front/rear arrangement. In Queensland planning language this is a Material Change of Use (MCU), almost always Code Assessable in the LMR (Brisbane), MD1 (Gold Coast), or equivalent zones. Casa Daily distinguishes dual occupancy from secondary dwelling (granny flat) — they trigger completely different planning paths.

Where SEQ dual-occupancy plays are happening

Brisbane: LMR sub-precincts across Carina, Tarragindi, Camp Hill, Norman Park, Aspley, Mansfield. Gold Coast: MD1 zones in Miami, Labrador, Ashmore. Sunshine Coast: Buderim, Mountain Creek, Coolum Beach. Moreton Bay: Strathpine, Margate, Scarborough — code-assessable dual occupancy with Moreton Bay's permissive frontage requirements. Logan: Springwood, Daisy Hill, Slacks Creek for sub-$800K dual occupancy with high yields. Redland: Birkdale, Wellington Point, Cleveland for premium bayside duplex plays.

What kills a dual-occupancy site

Frontage too narrow (most SEQ councils require 18-20m for code-assessable dual occupancy), depth too shallow (under 30m and the second dwelling can't meet setback), heritage or character overlay (binding TBC kills dual-occupancy intent), flood freeboard (lifts both slabs and erodes feasibility), bushfire BAL ≥29 (triggers expensive construction class), and side-boundary setbacks that don't accommodate a duplex pair. Casa Daily filters all of these in scoring.

Yield expectations

Code-assessable dual occupancy in middle-ring SEQ typically delivers: total project cost $1.4M-$2.0M (land + build), end-product value $1.7M-$2.5M (combined two dwellings), gross development margin 18-28%. As a hold-and-rent investment: combined gross rent $1,200-$1,800/wk, gross yield 5.5-7.5% depending on suburb. Casa Daily's feasibility snapshot factors actual local end-product values, not generic figures.

Common questions

Plain answers about dual-occupancy sites.

What's the difference between dual occupancy and a duplex?
In Queensland planning vocabulary, a duplex is a *type* of dual occupancy where the two dwellings are physically attached. Dual occupancy is the broader category and includes attached pairs (duplexes), detached pairs (two homes on one lot), and front/rear arrangements. Planning treatment is the same; design intent differs.
What zones permit dual occupancy in Brisbane?
Brisbane City Plan permits dual occupancy as Code Assessable in the Low-Medium Density Residential (LMR) zone in nominated sub-precincts. The Character Residential zones permit dual occupancy in some sub-precincts subject to additional design controls. Single-dwelling Low Density Residential (LDR) generally does NOT permit dual occupancy without an Impact Assessable MCU.
How long does dual-occupancy approval take?
Code Assessable dual-occupancy MCUs in Brisbane typically decide in 35-65 business days. Add 4-8 weeks for an Information Request cycle if the application package isn't tight. Total time from offer to operational works approval: 6-9 months for clean Code Assessable, 9-14 months for Impact Assessable.
Can I subdivide a dual-occupancy block later?
Yes — once both dwellings are built and certified, you can apply for a Reconfiguration of a Lot (RoL) to community-title the block, creating two separately-saleable lots. This is a common 'duplex then subdivide' play that turns a hold investment into two saleable properties.
