Subdivision rules in Brisbane
Building a subdivision in Brisbane? Brisbane City Council applies the Queensland planning framework. Here's what that means locally — plus the overlays worth checking on your specific block.
Reconfiguring a lot - assessed against your council's planning scheme
In Queensland subdivision is called reconfiguring a lot, and whether you can do it turns on the minimum lot size, frontage and lot shape your council's planning scheme sets for your zone and precinct. In Brisbane's Low Density Residential zone that is commonly 400 m² for a standard lot and 600 m² for a rear (battle-axe) lot, but each of Queensland's councils sets its own figures.
Key rules at a glance
| Minimum lot size | Set by your council's planning scheme for your zone and precinct - commonly 400-600 m² in low density residential zones, with rear lots typically larger (indicative), mapped per property |
| Approval needed | Development approval for reconfiguring a lot, unless the planning scheme lists it as accepted development |
| Assessed by | Your local council, as code assessable or impact assessable development under the Planning Act 2016 |
| Frontage | Set by the planning scheme - commonly 10-15 m for a standard lot, with a narrower access handle permitted for rear lots (indicative) |
| Typical timeframe | About 3-4 months for a compliant code assessable application (some councils offer a fast-track, such as Brisbane's RiskSMART), longer for impact assessment; roughly 9-18 months to titles overall (indicative) |
| Title created | Freehold lots on a sealed survey plan; a community titles scheme is the alternative where lots share common property |
| Final step | Council plan sealing, then lodgement with Titles Queensland |
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.
How often this applies in Brisbane
These are the overlays that can remove the fast-track, measured across every parcel in Brisbane from the same data behind our zoning map. They describe the council, not your block, and they are counted separately — one parcel can carry more than one, so they cannot be added together.
| Overlay | Share of parcels | What that means here |
|---|---|---|
| Heritage | 0.39% | 1,530 parcels flagged. The rest are mapped and sit outside it. |
| Flood | 20.93% | 82,937 parcels flagged. 79.07% of the council carries no flood mapping at all — unassessed, not cleared. |
| Bushfire | 11.57% | 45,855 parcels flagged. The rest are mapped and sit outside it. |
The most common zone in Brisbane is Low density residential, covering 60.0% of its 396,341 parcels. What you can build is decided by your own lot's zone, not the council's most common one.

Frequently asked questions
Do I need council approval for a subdivision in Brisbane?
Usually yes. In Queensland, a subdivision generally needs an application, and Brisbane City Council is the authority that assesses it. See the full state rules for the pathway and what's required.
Which council approves a subdivision in Brisbane?
Brisbane City Council is the consent authority for Brisbane (Greater Brisbane). You can review local planning controls on the council website and lodge through your state planning portal.
What is the minimum land size for subdivision in Queensland?
There is no statewide figure - it is set by your council's planning scheme for your zone and precinct. As an indicative example, Brisbane's Low Density Residential zone commonly requires 400 m² for a standard front lot and 600 m² for a rear lot, with a reduced figure close to some centres. Other councils use different numbers, so the only reliable answer is the one mapped for your address.
