Short answer: often yes, but Brisbane City Plan 2014 draws a hard line at the minimum lot size, and what sits below that line is not just "harder", it is a different assessment pathway. City Plan's categories of assessment make a reconfiguration code assessable where each new lot meets the size trigger for its zone, and impact assessable, with public notification, where a lot falls below it. One condition sits on top: for a simple one-lot-into-two split in most residential zones, the State's Planning Regulation sets its own default category of code assessment, and where an overlay applies to the land that default is displaced, with the resulting category read for the specific parcel rather than assumed. The numbers that decide which side you are on are set by your zone and precinct, not a single citywide figure, and every subdivision here needs a development application either way; under City Plan's tables of assessment there is no accepted, no-application pathway for it.
The minimum lot sizes, by zone and precinct
City Plan 2014's Subdivision code (Table 9.4.10.3.B, Parts 1 to 4) sets the minimum lot size by zone and precinct. These are the figures re-read directly from the operative version 36.00/2026 text on 3 July 2026:
| Zone / precinct | Minimum lot | Table part |
|---|---|---|
| Low density residential (LDR) / Character / Low-medium density residential (LMR) / Emerging community, standard lot | 450 m² (14 m x 20 m rectangle, 15 m average width) | Part 1 |
| LDR, small lot baseline | 400 m² (9 m x 15 m, 10 m average width) | Part 2 |
| LDR, small lot, development-average concession | 350 m² (6 m x 15 m, 10 m average width) | Part 2 |
| LDR, small lot, walk-to-centre concession | 300 m² (6 m x 15 m, 7.5 m average width) | Part 2 |
| LDR, rear lot | 600 m² (14 m x 20 m, 15 m average width) | Part 3 |
| Character residential, Infill housing precinct | 300 m² (6 m x 15 m, 7.0 to 7.5 m) | Part 2 |
| LMR, 2 storey mix precinct | 260 m² (6 m x 15 m, 7.0 to 7.5 m) | Part 2 |
| LMR, 2 or 3 storey mix precinct | 260 m² (6 m x 15 m, 6.5 to 7.5 m) | Part 2 |
| LMR, up to 3 storeys precinct | 180 m² (6 m x 15 m, 6.0 to 7.5 m) | Part 2 |
| Rural residential | 10,000 m² (1 hectare) (14 m x 20 m, 40 m average width) | Part 4 |
The 450 m² Part 1 figure is the standard; the Part 2 small-lot rows are alternative minimums a proposal can elect to meet instead, each carrying its own frontage and design conditions alongside the smaller area. Rural residential land needs a full hectare per lot, and land mapped in the SEQ Regional Landscape and Rural Production Area needs 100 hectares per lot unless an exemption applies.
The trap: code above the line, impact below it
City Plan does not simply make a sub-minimum split harder, it reclassifies the application. Table 5.6.1 sets a lot-size trigger per zone, and a reconfiguration proposing a lot below the trigger becomes impact assessable: publicly notified and assessed on broader merits. The triggers for the main residential zones, read from the operative version 36 text on 7 July 2026:
- Low density residential: impact where a proposed lot is below 400 m² and the lot is more than 200 m walking distance from qualifying Centre-zoned land (sites in a Centre zone totalling more than 2,000 m²), below 300 m² where it is within 200 m of such land, or below 600 m² for a rear lot.
- Low-medium density residential: impact where a proposed lot is below 260 m² in the 2 storey mix or 2 or 3 storey mix precincts, below 180 m² in the Up to 3 storeys precinct, or below 350 m² for a rear lot, in each case where there is no associated assessable material change of use application.
- Character residential: impact where a proposed lot is below 450 m², or below 600 m² for a rear lot.
Note the two layers: these triggers set the assessment category, while the Subdivision code's minimums in the table above are the design benchmarks the application is then assessed against, and in some zones the two numbers differ. And for a simple one-into-two split in most residential zones, the State Regulation's own category layer applies first, code assessment by default; where an overlay applies to the land, that default is displaced, and the resulting category needs to be read for the specific parcel. Separately, the Subdivision code adds structure-planning benchmarks (its Section C) once a reconfiguration creates 20 or more lots, a Low density residential site exceeds 7,000 m², or a new road is opened; that adds assessment content rather than changing the category.
The concession that lowers the bar, and where it does not apply
Brisbane's small-lot rows in Part 2 exist because the scheme deliberately allows smaller lots close to centres and in higher-density precincts. The walk-to-centre concession is the one worth checking before assuming your block is stuck at the standard or small-lot baseline. The scheme's own words, Table 9.4.10.3.B Part 2 (verified 3 July 2026):
"Where any part of the lot frontage is within 200m walking distance of any part of the lot frontage of a site or sites in a zone in the Centre zones category with a combined site area of more than 2,000m2."
The test is the zoning category of the nearby land, a Centre zone (neighbourhood, district, major or principal centre), not whether a shop happens to trade there. Land zoned Industry does not qualify even where a large retail complex operates on it, and a neighbourhood centre can enliven the concession just as much as a major one, provided the combined site area of the qualifying centre land exceeds 2,000 m² within 200 m walking distance of the lot's frontage. Whether a specific parcel clears that test is a mapping and walking-distance question, not something to assume from the surrounding streetscape.
In the Aspley area, a lot near a district centre used this concession to complete a one-into-two split at 330 m² and 300 m², recorded on the public title register. A different lot nearby tested at roughly 620 m walking distance from the nearest Centre zone, with no Centre-zoned land within 400 m, so the concession does not fire there and the standard or small-lot baseline minimums govern. Same general area, different result, because the test is measured from each lot's own frontage.
If a freehold split does not clear the line, dual occupancy is often still open, in LMR
Where your block cannot produce two compliant lots, Brisbane's dual occupancy pathway is worth checking, but it does not exist everywhere in the same form. In the Low-medium density residential (LMR) zone, a dual occupancy is code assessable where the design stays within the zone table's height and precinct tests (the Dual occupancy code's 600 m² site and 15 m frontage figures are design benchmarks tested inside that assessment, not the category gate): up to 3 storeys / 11.5 m in the Up to 3 storeys precinct; in the 2 or 3 storey mix precinct the 3-storey height applies only where the road reserve is at least 15.5 m and part of the site is within 400 m walking distance of a rail or busway station, otherwise that precinct, like the 2 storey mix precinct, is capped at 2 storeys / 9.5 m. Above the height thresholds it becomes impact assessable. In the Character residential zone, dual occupancy is code assessable only in the Infill housing precinct, and only where any house constructed in 1946 or earlier is retained and the building stays within 2 storeys and 9.5 m; outside those conditions it falls to impact assessment. The Dual Occupancy code's design benchmark for that precinct is a minimum site of 800 m² with 20 m of frontage.
Low density residential (LDR) works differently, and this is not a fallback most LDR owners have. Dual occupancy is not listed as a use in the LDR Table of Assessment, defaulting it to impact assessable, and the LDR zone code states its own intent directly. The scheme's own words, Low density residential zone code 6.2.1.1 (verified 3 July 2026):
"Development maintains a low density character in which multiple dwellings are not accommodated".
A dual occupancy in LDR is not ruled out entirely, the Dual Occupancy code does carry an LDR benchmark (2 storeys / 9.5 m on a 3,000 m² / 40 m frontage site), but only as an impact-assessable, large-site outlier, not a code pathway. For most LDR blocks, a secondary dwelling (granny flat) is the pathway the zone is built for instead.
What the flood overlay does, and what is still routed
Brisbane's flood overlay works differently to a simple risk-tier system: under Table 5.10.11, the Flood overlay's table of assessment,, even land mapped in the highest flood sub-category can still see a new dwelling house assessed as accepted development, where a dwelling house is accepted in the zone and the design meets every acceptable outcome in section A of the code, and missing one of those outcomes moves the assessment to code, not impact. Whether your parcel's flood mapping, or any other overlay such as heritage, waterway corridors or bushfire, adds conditions to a reconfiguration is a lot-by-lot mapping question, read on Brisbane's eplan viewer for your parcel rather than assumed.
How to check your own block
- Find your parcel on Brisbane's City Plan eplan and confirm its zone and precinct. That sets which row of Table 9.4.10.3.B applies to your minimum lot size.
- Check whether any part of your lot's frontage sits within 200 m walking distance of a Centre-zoned site or sites totalling more than 2,000 m², which in the Low density residential zone can unlock the 300 m² small-lot concession.
- Sketch the split and check each resulting lot clears its minimum area, frontage and rectangle dimensions with margin; a lot below the zone's trigger changes the assessment pathway.
- Check the overlay maps that touch the parcel, flood, heritage, waterway corridors and any others, and read what each one requires for your specific design rather than assuming a citywide rule.
