Can I Subdivide My Block? Step-by-Step

Can I subdivide my block? It depends on a short list of tests: whether your zone allows it and each new lot can meet the minimum lot size, density and frontage rules, whether overlays such as heritage, bushfire or flood get in the way, whether every lot can be serviced and accessed, and whether anything on your title stops it. There is no national rule, so the answer is always specific to your address and your state.

The checklist below works in every state and territory. Steps 1 and 2 test whether the numbers work. Steps 3 to 7 cover what could stop or complicate a subdivision, and who decides.

A note on the words used

In Queensland the official term is reconfiguring a lot, under the Planning Act 2016. In South Australia it is land division. In the ACT, land is leasehold, so subdividing means changing a Crown lease: creating new Crown leases, or unit titling over one lease. Elsewhere it is simply subdivision.

Step 1: Find your zone and the planning scheme that applies

Everything starts with your zone, and the planning instrument it sits in differs by state.

State	Planning rules that apply	Where to look up your zone
NSW	Your council's Local Environmental Plan (LEP), plus its Development Control Plan (DCP)	NSW Planning Portal Spatial Viewer, or a section 10.7 planning certificate from council
VIC	Your council's planning scheme: the zone clause and its schedule, overlays and Clause 56	The planning property report for your address, from VicPlan
QLD	Your council's planning scheme, including its reconfiguring a lot code	Your council's planning scheme (zone, precinct and overlays)
SA	The statewide Planning and Design Code	The SA Property and Planning Atlas (SAPPA), or the online Code
WA	Your council's local planning scheme (zone and R-Code), applied with the Residential Design Codes (R-Codes)	Your council's local planning scheme
TAS	The Tasmanian Planning Scheme: State Planning Provisions plus your council's Local Provisions Schedule. Kingborough still uses its Interim Planning Scheme 2015	A PlanBuild Tasmania Property Report
ACT	The Territory Plan 2023	ACTmapi
NT	The NT Planning Scheme 2020, which applies across the NT except Jabiru	The "town planning" zones layer of NT Atlas

Read the rules in force today. In the ACT, Major Plan Amendment 04 commenced on 1 July 2026. In the NT, amendment PA2026/0205 had not been made at 6 October 2026, so 800 m² still applies in established Zone LR areas.

Step 2: Test the minimum lot size, density and frontage

There is no national minimum lot size. Each state sets its own, usually by zone, and the test is not always one number. WA applies both a minimum and an average site area. Tasmania's General Residential Zone also requires each lot to fit a building area of at least 10 m x 15 m, with a gradient no steeper than 1 in 5.

State	Where the lot size rule lives	Example from our state guides
NSW	The Lot Size Map in your council's LEP, plus any LEP clauses that vary it	Newcastle LEP 2012 clause 4.1A allows a residential lot down to 200 m² where a dual occupancy or multi dwelling development is approved at the same time
VIC	The zone clause and its schedule	The General Residential and Residential Growth Zones set no minimum lot size in the zone clause
QLD	Your council's planning scheme, usually its reconfiguring a lot code, by zone and precinct	Logan lists 400 m² for the suburban precinct of the Low density residential zone
SA	Each zone's minimum site area and frontage in the Planning and Design Code, sometimes set by a mapped technical and numeric variation	Figures can differ for detached, semi-detached, row or group dwellings
WA	Table D of the R-Codes Volume 1, for your R-Code	At R20 the minimum is 350 m² and the average is 450 m², so two lots generally need at least 900 m²
TAS	Zone acceptable solutions in the State Planning Provisions	General Residential: 450 m² with a 12 m frontage
ACT	The Planning (Subdivision) Technical Specifications 2026	RZ1: 350 m² for each new block, excluding any battle-axe handle
NT	Table A to clause 6.2.1 of the NT Planning Scheme 2020	Zone LR: 800 m², other than in greenfield areas identified for compact urban growth

Is the minimum a hard limit?

Not always, and the room to move differs by state:

NSW: clause 4.6 of the LEP lets you ask council to vary a development standard such as minimum lot size, except for subdivision in some rural, environmental and large lot residential zones.
QLD: in the Gold Coast and Logan, a lot below the minimum makes the application impact assessable. It must then be publicly notified, and submitters can appeal.
SA: missing a deemed-to-satisfy figure is not an automatic refusal, but the proposal has to show the outcome is met another way.
WA: the WAPC can approve a lot up to five per cent below Table D where the R-Codes design principles are met, limited to one lot in the subdivision.
TAS: in General Residential and Low Density Residential, a lot that misses the acceptable solution can be assessed against the performance criteria. Kingborough's interim scheme has no performance route below its minimums.
ACT: the Territory Planning Authority may approve an application that does not satisfy the technical specifications where it meets all relevant assessment outcomes.
NT: in Zone LR, no lot may be more than 5% below the Table A minimum, which is 760 m² against 800 m².

Frontage, access and rear lots

Every new lot needs workable access, and rear (battle-axe) lots often have their own rules:

In WA, Operational Policy 2.2 says the battle-axe configuration is not favoured and the WAPC will not reduce lot sizes for battle-axe lots. The access leg should be at least 4 metres wide at R2 to R40.
In Tasmania, a rear lot usually relies on a performance criterion: a frontage or right of carriageway sufficient for the intended use and not less than 3.6 m wide.
In the ACT, minimum block areas exclude any battle-axe handle.
In the NT, clause 6.2.1 says "There are no battle-axe lots", unless the consent authority is satisfied a variation is consistent with the purpose of the clause and the zone purpose and outcomes.

The existing house

A house you keep has to work on its smaller lot. In South Australia, a building that would straddle a proposed boundary has to be altered or removed. In Tasmania's General Residential Zone, existing buildings are expected to be consistent with the required setbacks to the new boundary.

Step 3: Check overlays and constraints

Overlays and registers can add a permit, a referral or a specialist report. A listing or hazard does not always rule out a subdivision.

Heritage. Check the state or territory heritage register and your council's local list or overlay. In Victoria, the Heritage Overlay requires a permit to subdivide. In Queensland, a clear state search does not clear local heritage.

Aboriginal cultural heritage. Each state and territory has its own law. In Victoria, subdivision into three or more lots in an area of cultural heritage sensitivity can require a cultural heritage management plan. In the NT, all Aboriginal sacred sites are protected, and an Aboriginal Areas Protection Authority Abstract of Records is the usual first check.

Environment. Clearing native vegetation usually needs approval, for example under Clause 52.17 in Victoria, the Native Vegetation Act 1991 in SA or, unless an exemption applies, a DWER permit in WA.

Bushfire. In NSW, subdividing bush fire prone land for residential purposes needs a bush fire safety authority from the NSW Rural Fire Service. In WA, a subdivision in a designated bush fire prone area can trigger State Planning Policy 3.7. In the ACT, blocks in a bushfire prone area are not developed where the bushfire attack level for later buildings exceeds BAL 29.

Flood. Flood controls usually come from council or state mapping, and being outside it is not proof of no risk. In SA, being outside the Code's flood overlays is not the same as having no flood risk, and WA's floodplain mapping covers major river flooding only. In WA's mapped floodway, new buildings are not permitted.

Contamination. Each state keeps its own register or mapping, such as Queensland's Environmental Management Register and Contaminated Land Register, the EPA's Site Contamination Index in SA and DWER's Contaminated Sites Database in WA. Past land uses still matter where a site is not listed.

Step 4: Check servicing: water, sewer, power and access

Each new lot generally needs water, sewer, power, stormwater and access. Some schemes write this into the lot rules:

In WA, State Planning Policy 2.9 Water says that in sensitive water resource areas, subdivision below one hectare should only occur with reticulated sewerage.
In Tasmania's General Residential Zone, the acceptable solutions require each lot to connect to a full water supply service and reticulated sewerage, and to be capable of connecting to a public stormwater system.
In the NT, lots in Zones LR, LMR, MR and HR are to be connected to reticulated services.

Your water authority, such as Sydney Water, SA Water, Water Corporation in WA or TasWater, sets the requirements. Limited capacity, a main crossing the lot or a needed main extension can add real cost. In Victoria and Tasmania, crossovers and vehicle access should meet the road authority's requirements.

Step 5: Check your title: covenants, easements and restrictions

A current title search can show:

Easements, such as for sewer mains, which can block a building area or driveway.
Restrictive covenants, which can limit building or further subdivision. In Victoria, removing or varying one under section 23 of the Subdivision Act 1988 needs a permit under Clause 52.02.
Agreements recorded on title, such as a section 173 agreement in Victoria, which binds future owners and can prohibit or restrict development, or a land management agreement in SA.
Statutory covenants in Queensland and notifications in WA.
In the ACT, the Crown lease itself: its purpose clause and any development covenant set what the lease allows now.

Step 6: Who approves it in your state

The decision-maker is not always your council. The statutory clocks cover the decision stage only. Meeting conditions, building works and getting new titles usually take longer.

State	Who decides	Statutory decision time	Who registers the new titles
NSW	Usually your local council, sometimes a local planning panel	40 days, or 60 days for integrated development, before a DA is treated as refused for appeal purposes	NSW Land Registry Services
VIC	Your local council, for the permit, certification and statement of compliance	60 days, or 10 business days for VicSmart	Land Services Victoria
QLD	Your local council as assessment manager, with referral to SARA where a state interest is involved	35 business days, which can be extended by agreement	Titles Queensland
SA	For land division consent, the council's assessment manager, or an accredited professional surveyor where no public road is created	Land division consent: 30 business days for 10 allotments or fewer with no new public road	Land Services SA
WA	The Western Australian Planning Commission (WAPC). Your council is a referral body	90 days, unless you agree in writing to a longer period	Landgate
TAS	Your local council, as planning authority. It also seals the final plan	28 days if permitted, 42 days if discretionary	Recorder of Titles (Land Titles Office)
ACT	The Territory Planning Authority	30 working days for a standard DA with no representations	Land Titles Office (Access Canberra)
NT	The Development Consent Authority division for your area, or the Minister outside division areas	The NT Government says applications are usually processed in eight weeks	Land Titles Office

Step 7: Next steps and who to talk to

Gather the paperwork. A zone report or planning certificate, such as a section 10.7 certificate in NSW or a planning property report in Victoria, and a current title search.
Talk to a licensed surveyor. The surveyor prepares the plan of subdivision, and in SA usually manages the application too.
Bring in a town planner where the proposal relies on discretion, such as a clause 4.6 request in NSW or a discretionary application in Tasmania.
Ask your water authority early about capacity and connection requirements.
Use pre-lodgement options where they exist. In SA, section 123 of the Planning, Development and Infrastructure Act 2016 lets you reach an agreement with a referral agency before lodging. In the NT you can book an optional pre-application forum.

Application fees are set by the state or by each council and change every year; our state guides list them. Surveyor, planner and engineer fees are quoted on scope, and a Subdivision Checker report gives indicative costs for your property. See what one covers in our sample report.

Common reasons a block can't be subdivided

It is too small. It misses the minimum, or in WA the average. An R20 lot under 900 m² generally cannot be split in two under today's Table D.
The zone does not allow it. In South East Queensland's Regional Landscape and Rural Production Area, reconfiguring a lot is prohibited development unless an exemption applies. In SA, a land division creating additional residential allotments in an environment and food production area must be refused.
There is no workable access for a rear lot, or the frontage is too narrow.
The second home is a granny flat. A lot with a secondary dwelling cannot be subdivided in NSW, and Victoria, the ACT and the NT have their own limits on titling one.
A hazard is too severe, such as WA's mapped floodway, where new buildings are not permitted, or a bushfire attack level above BAL 29 in the ACT.
Services cannot reach it, or the mains lack capacity.
The title restricts it, through a covenant, easement or agreement.

Check your own block

A Subdivision Checker report applies these rules to one address, covering planning and zoning, heritage, environment, bushfire, flood, servicing, contamination and title, plus indicative costs. It is a starting point, not a substitute for a licensed surveyor or town planner. Order a report for your address.

Frequently asked questions

Can I subdivide my block?

It depends on a short list of tests: your zone, the minimum lot size and frontage rules, overlays such as heritage, bushfire or flood, whether each lot can be serviced and accessed, and what is on your title. Each state and territory sets its own rules, so the answer is specific to your address.

How do I find out if a property can be subdivided?

Start with your zone, using official tools such as the NSW Planning Portal Spatial Viewer, a planning property report from VicPlan, the SA Property and Planning Atlas, ACTmapi or NT Atlas. Then test lot size and frontage, check overlays, servicing and title, and have a licensed surveyor or town planner confirm what applies.

Is there a national minimum lot size for subdivision?

No. Each state and territory sets its own, usually by zone. For example, WA's R20 code has a 350 m² minimum and 450 m² average site area, the ACT's RZ1 zone needs 350 m² for each new block, and the NT's Zone LR is 800 m² outside compact-growth greenfield areas.

What if my block is just under the minimum lot size?

It depends on the state. In NSW you can ask council to vary the standard under clause 4.6 of the LEP. In Logan and the Gold Coast a smaller lot makes the application impact assessable. In WA the WAPC can approve one lot up to five per cent below Table D, and in the NT's Zone LR no lot may be more than 5% below the minimum.

Who approves a subdivision?

Usually your local council in NSW, Victoria, Queensland and Tasmania. In South Australia land division consent comes from the council's assessment manager or, where no public road is created, an accredited professional surveyor. In WA it is the Western Australian Planning Commission, in the ACT the Territory Planning Authority, and in the NT the Development Consent Authority.

Can I subdivide off a granny flat?

Generally not. In NSW a lot with a secondary dwelling cannot be subdivided. Victoria and the ACT also stop a small second dwelling or secondary residence getting its own title, and in the NT an independent unit cannot be titled through a unit title scheme.
