There is no single state-wide minimum. It comes from your council’s planning scheme and your lot’s zone, and Brisbane City Council has been amending its small-scale housing provisions (including those for secondary dwellings), so a figure quoted in an article written last year may already be out of date. Rather than publish a number that could be wrong for your lot, we check yours at the free site assessment on Queensland Globe (the official cadastral viewer) against the current City Plan provisions and any overlays, and report the answer to you in writing before any contract.

The Queensland Development Code is the state-wide set of building-related standards, and Mandatory Parts 1.1 and 1.2 are the design and siting standards for detached housing — setbacks, site cover, height and the like — which apply unless your council’s planning scheme sets alternative provisions, in which case the council’s prevail. They have not been substantially updated in over a decade, and the Queensland Government has developed a new Queensland Housing Code to replace QDC Parts 1.1 and 1.2, proposed to commence on 1 September 2026 subject to Governor-in-Council approval, with a three-year transition period during which councils adopt it. If you are planning a build across that changeover, the practical answer is that we confirm which standard applies to your lot in writing at the site assessment rather than assuming.

Yes. Since 26 September 2022 a Queensland secondary dwelling can be rented to anyone, related to the main household or not — a Planning Regulation amendment removed the restriction state-wide. Which agreement applies depends on the physical arrangement, not on a lease count: the Residential Tenancies Authority treats a self-contained dwelling with no access to the main house as a general tenancy, and an arrangement where tenants share the kitchen or other facilities as rooming accommodation. Note also that once a secondary dwelling is let separately the building code’s additional fire and sound-transmission requirements apply. (An earlier version of this answer said "Class 1a allows up to 3 separate leases per lot without a rooming-house licence" — that was wrong. NCC Class 1a and Class 1b are building classifications, not permitted lease counts.)

Construction is the same four weeks on site as Melbourne. The approvals stage typically runs about one to one and a half months in SEQ, because the building approval sits with a private certifier and any council development application sits with the council on top of that. Decision to finished build is typically two to two and a half months on a straightforward lot; leasing usually follows two to three weeks after handover. Overlay lots — flood, bushfire, heritage, biodiversity — change the pathway, and where one applies we confirm the timing in writing after the site assessment rather than estimating it here.

Yes — anywhere in SEQ within ~80 km of Brisbane CBD. Sunshine Coast, Caboolture, Moreton Bay, Logan, Ipswich, Redland and Gold Coast are all serviced. Travel allowance for sites > 60 km from Brisbane is included up to a fixed $1,500 cap.
