Can you subdivide?
Whether your Brisbane block can be split comes down to three things, all controlled by Brisbane City Plan 2014: the zone it sits in, the minimum lot size that applies in that zone, and any overlays on top.
This page covers zone and lot size. Overlays are on their own page — that's where most subdivisions actually fail.
The core test
If you can split your block into multiple lots, each of which still meets the zone's minimum lot size, you've cleared the basic hurdle. That's necessary but not sufficient.
Look up your zone on Brisbane's eMaps tool — search your address, the zone shows in the side panel.
Low density residential (LDR)
The dominant zone in Brisbane's suburbs. Single houses on standalone lots. This is where most subdivisions happen.
| Lot type | Minimum size | Minimum frontage | Assessment |
|---|---|---|---|
| Standard front lot | 450 m² | 10 m | Code-assessable |
| Rear lot (battle-axe) | 600 m² excluding access strip | — | Code-assessable |
| Small lot (front) | 400 m² | 10 m | Impact-assessable |
| Small lot (rear) | 600 m² excluding access strip | — | Impact-assessable |
Brisbane City Plan 2014, §9.4.10 Subdivision code, Table 9.4.10.3.B
What "small lot" means. Lots under 450 m² are classified as small lots. They have to meet additional design and streetscape requirements (specified in §9.3.10 Dwelling house (small lot) code) and they're impact-assessable — meaning the application goes through public notification, neighbours can object, and Council can refuse on broader grounds than just the code. Slower, more uncertain, more expensive.
The math. To split an 800 m² LDR block into two standard 450 m² lots, you'd need 900 m² to spare. To split it as small lots at 400 m² each, 800 m² is exactly enough — but you're now in impact-assessable territory.
The Centre uplift (300 m² small lots)
If your LDR property is within 200 metres walking distance of a Centre zone of at least 2,000 m², you may qualify for small lots at 300 m² minimum.
| Lot type | Minimum size | Minimum frontage |
|---|---|---|
| Small lot (front), near Centre | 300 m² | 7.5 m |
| Small lot (rear), near Centre | 600 m² | — |
Brisbane City Plan 2014, §9.4.10.3.B
"Walking distance" means the route a pedestrian would actually take — along roads with footpaths or off-road pathways — not the crow's-flight distance. A property 180 m straight-line from a Centre might be 250 m walking and not qualify.
Heads-up: amendment in progress. BCC consulted from February–March 2026 on expanding this from 200 m to 300 m walking distance, as part of the More Homes, Sooner package. Final implementation timing isn't published at the time of writing.

Other residential zones
| Zone | Min lot size (front / rear) | Notes |
|---|---|---|
| LMR (2 storey or 2–3 storey mix) | 260 m² / 350 m² | Townhouses, apartments, dwelling mixes |
| LMR (up to 3 storey) | 180 m² / 350 m² | Higher density precincts |
| CR1 Character | 450 m² / 600 m² | Pre-1947 character protection applies |
| CR2 Character infill | 300 m² / 450 m² | Character zone with infill allowance |
| Rural residential | 10,000 m² | Acreage; rarely subdividable |
Brisbane City Plan 2014, §9.4.10.3.B
What about MDR and HDR?
Medium and High Density Residential zones don't have a "minimum lot size for subdivision" in the same simple sense — they're typically developed as multiple-dwelling lots (townhouses, apartments) on a single title. Subdivision happens at the certified-plan stage of a larger development, not as an isolated split. If you're in MDR or HDR, talk to a planner — the rules work differently.
What this page doesn't tell you
Zone and lot size are the floor, not the ceiling. Even a perfectly-sized block can fail because of:
- Overlays — heritage, character, flood, waterway, bushfire. Any of these can be fatal.
- Configuration — can two compliant lots actually fit, given your frontage, depth, slope, and existing buildings?
- Site-specific — trees on the significant tree register, existing easements, soil contamination, sloped land needing retaining.
A 1,000 m² LDR block in Upper Mount Gravatt is probably subdividable. The same 1,000 m² block 50 m from a creek with a waterway corridor overlay almost certainly isn't.
