Can You Subdivide a Dual Occupancy?

Can you subdivide a dual occupancy? Sometimes. Building two homes on one lot and giving each home its own title are two different approvals, and getting the first does not mean you will get the second. Whether the second step is allowed depends on your state or territory, your zone and local rules such as minimum lot size, and on which kind of title the rules allow for your land.

The words change across the country. NSW says dual occupancy, Victoria says two dwellings on a lot, WA says grouped dwellings, the ACT talks about multi-unit housing, and the NT says dwelling-group. Below is what each state and territory's rules say about the two steps, with a comparison table.

Two approvals, not one

Step one: approval to build two homes on one lot. Depending on the zone, this usually means a planning approval for the dwellings themselves. It leaves you with two homes on a single title.

Step two: approval to put them on separate titles. This is a subdivision, and it comes in two broad forms:

Torrens or green title subdivision, which creates separate lots of land, each with its own title.
A strata, community or unit title scheme, which divides the site into lots that can sit alongside common property, in some states with a body corporate or owners corporation.

Which of these is available, and on what lot size, is set by state legislation and the planning rules for your zone. Some places link the steps, for example by letting you subdivide once the dwelling approval exists. Others treat them separately.

A granny flat is a different case again. Several states and territories keep a secondary dwelling with the main house, and some expressly stop it being split off (see below).

New South Wales

Since 1 July 2024, dual occupancies and semi-detached homes are permitted with consent in the R2 Low Density Residential zone across NSW. Building one and subdividing it are separate questions, and the answer to the second sits mostly in your council's Local Environmental Plan (LEP).

In low and mid-rise housing areas (land within 800 metres walking distance of a nominated town centre or station in Greater Sydney, the Central Coast, the Lower Hunter and Newcastle, and Illawarra-Shoalhaven), the state's dual occupancy standards include a 450 m² minimum lot size and 12 m width, with subdivision down to 225 m² and 6 m width per lot in the R1, R2 and R3 zones. Some council areas and hazard-affected land are excluded.

Elsewhere, local clauses decide. Newcastle LEP 2012 clause 4.1A, for example, allows a residential lot to be subdivided down to 200 m² where a dual occupancy or multi dwelling development is approved at the same time. Northern Beaches Council's draft LEP, exhibited from 20 July 2026, would allow a lot with an existing or proposed dual occupancy in R2 to be subdivided where each resulting lot is at least 400 m² and has one dwelling. It is not in force, and Council expects it to commence in mid-2027. See our Northern Beaches draft LEP article.

NSW offers Torrens subdivision, finished with a subdivision certificate, or strata subdivision under the Strata Schemes Development Act 2015, where the strata plan needs a strata certificate before NSW Land Registry Services will register it. In 2026/27 the council DA fee for strata subdivision is $458 plus $65 per additional lot. Minimum lot size rules can still prevent a strata subdivision in some areas, so check how your LEP treats each type. A lot with a secondary dwelling cannot be subdivided. More in our NSW subdivision guide.

Victoria

In the General Residential Zone, a planning permit is required to construct two or more dwellings on a lot, or a dwelling where at least one already exists (clause 32.08-7). Since Amendment VC288 took effect on 16 October 2025, planning applications for two homes on a lot can use VicSmart in six zones, including the General Residential, Neighbourhood Residential and Residential Growth zones, if they meet all the relevant rules. Planning Victoria says an eligible application can be approved within 10 business days.

VC288 also added VicSmart classes for two-lot subdivision. One applies where a permit has been issued under a residential zone to construct up to two dwellings, the permit has not expired, and each lot will contain one existing or permitted dwelling. The Low Density Residential Zone is excluded from that class. Planning Victoria notes that applications affected by heritage, flooding, bushfire and certain other controls may not be eligible.

In 2026-27 a VicSmart application to subdivide is $233.10 and a standard permit to subdivide into two lots is $1,537.00. The new titles only exist once Land Services Victoria registers the plan. A shared driveway created as common property brings an owners corporation. A permit must not be granted that would create a separate lot for land containing a small second dwelling. More in our Victoria subdivision guide.

Queensland

Whether a dual occupancy can be built is set by each council's planning scheme, by zone. Brisbane City Plan 2014, for example, defines dual occupancy as "the residential use of premises containing 2 dwellings on one lot (whether or not attached), or 2 dwellings on separate lots that share common property". Under Brisbane's More Homes, Sooner amendment, in force from 18 September 2026, dual occupancies in the new Low-medium density residential (3 or 4 storey mix zone) precinct became accepted development, with a 400 m² minimum lot size outside Key Locations.

Splitting an existing dual occupancy into separate titles is reconfiguring a lot, Queensland's term for subdivision, and generally needs a development approval from council. A standard format plan defines the land using marks on the ground, while a building format plan uses the building's structure, usually with a body corporate. More in our Queensland subdivision guide.

South Australia

The Planning and Design Code sets the rules statewide. The Eyre Peninsula councils' dwellings fact sheet defines types that put more than one home on land, including semi-detached dwellings (one of two dwellings joined side by side) and group dwellings (one of a group of two or more detached buildings, at least one of which has a site without a frontage to a public road), and recommends speaking with your council if you wish to build more than one dwelling on land. Each zone's minimum site area and frontage can differ for detached, semi-detached, row or group dwellings.

Separate titles need land division consent and planning consent, which together form your development approval. Land Services SA describes Torrens title as at least two allotments held independently, and community title as at least two lots and an area of common property. It is no longer possible to create new strata divisions. More in our SA subdivision guide.

Western Australia

Under the Residential Design Codes, a dwelling on a freehold lot is a single house, except where there is more than one dwelling on the lot, which makes them grouped dwellings. Table D of the R-Codes Volume 1 sets a minimum and an average site area per dwelling for each density code. At R20 these are 350 m² and 450 m².

Separate titles need Western Australian Planning Commission (WAPC) approval. Green title lots and survey-strata lots use the same application, Form 1A. Survey-strata lots consist only of surveyed land boundaries, although a survey-strata plan may include common property. Splitting a site where buildings already stand into built strata lots uses a separate WAPC form, Form 15A.

A proposal announced in July 2026 to abolish the average lot size for R20 and below is not in force. The department says amendments are anticipated to begin coming into effect from mid to late 2027, subject to consultation, endorsement and approval. More in our WA subdivision guide.

Tasmania

The State Planning Office's Residential Zone fact sheet shows other forms of housing as permitted in the General Residential Zone where they meet certain rules. The acceptable solution for multiple dwellings is a site area of not less than 325 m² per dwelling (clause 8.4.1). Strata schemes fall under the Strata Titles Act 1998, a pathway separate from subdivision.

A subdivision into separate lots needs a council planning permit, and the council later seals the final plan. In the General Residential Zone the acceptable solution is 450 m² per lot with a 12 m frontage. As at early October 2026, a secondary residence has a gross floor area of not more than 60 m² and shares access, parking and service connections with the main house. A draft amendment would raise that to 90 m², and the Tasmanian Planning Commission has asked whether it should preclude converting a primary and secondary residence to strata title. More in our Tasmania subdivision guide.

Australian Capital Territory

In RZ1 and RZ2, the Territory Plan's Residential Zones Policy lists subdivision, multi-unit housing and secondary residences as permitted uses. Since 1 July 2026, under the Missing Middle reforms, subdivision in RZ1 is permitted where each new block contains a lawfully constructed dwelling, or each new block is at least 350 m².

There are two paths. Block subdivision creates new blocks, each with its own Crown lease. Unit titling keeps one Crown lease and registers a units plan over it. In RZ1 unit titling is allowed only once all dwellings are lawfully constructed, and on a standard block only where it is at least 600 m². For development applications submitted from 1 July 2026 to 30 June 2027, the lease variation charge to split a lease into two or three leases is $7,500 for each additional lease. The 2026 unit titling fee for a two-unit residential development is $2,851.52. A secondary residence cannot be given a separate title or unit title. More in our ACT subdivision guide.

Northern Territory

In Zone LR (Low Density Residential), "dwelling-single" and "dwelling-independent" are already allowed, while dwelling-group and dwelling-multiple are currently prohibited. An independent unit cannot get a separate title through a unit title scheme, and a separate freehold title is only possible if the subdivision meets every requirement of the NT Planning Scheme 2020, including the minimum lot size (800 m² in established Zone LR areas, which can be reduced by no more than 5%).

The NT's Land Titles Office takes Form 21 for separate titles by plan and Form 113 for a unit title scheme. Proposed amendment PA2026/0205 would make dwelling-group and dwelling-multiple in Zone LR need a development permit, at up to one dwelling per 450 m², and cut the Zone LR minimum lot size to 450 m². As at 2 October 2026 it had not been made. More in our NT subdivision guide.

The table is a summary. Rules differ between zones and councils, and drafts noted above are not in force.

Granny flats are a different case

In several jurisdictions the rules keep a granny flat with the main house:

NSW: a lot on which a secondary dwelling (granny flat) is built cannot be subdivided.
VIC: a permit must not be granted which would allow a separate lot for land containing a small second dwelling.
TAS: a secondary residence sits on the same lot as a single dwelling and shares its access, parking and service connections.
ACT: a secondary residence, up to 90 m², cannot be given a separate title or unit title.
NT: an independent unit cannot be separately titled through a unit title scheme.

Two separately titled homes need the dual occupancy and subdivision rules, not the granny flat rules.

What decides it for your block

Whatever the state, the same questions come up:

Does your zone allow two dwellings, and on what lot or site area?
Which title types are available, and on what minimum lot size?
Must the second home be approved, or built, before you subdivide?
Do heritage, bushfire, flood or other overlays rule out a fast-track pathway?

You can see how a report sets out these issues for one address in our sample report.

Frequently asked questions

Can you subdivide a dual occupancy?

Sometimes. Building two homes on one lot and giving each home its own title are separate approvals, and getting the first does not mean you will get the second. Whether the second step is allowed depends on your state or territory, your zone and local rules such as minimum lot size, and on which kind of title the rules allow.

Can I subdivide a dual occupancy in NSW?

Often, but it depends on your council's LEP and on whether the land is in a low and mid-rise housing area. Since 1 July 2024 dual occupancies have been permitted with consent in the R2 zone across NSW, but subdividing one is a separate question. In low and mid-rise housing areas, the state's standards allow subdivision of a dual occupancy down to 225 m² and 6 m width per lot in the R1, R2 and R3 zones.

Can I build two homes and then subdivide in Victoria?

A planning permit is needed to construct two or more dwellings on a lot in the General Residential Zone. Since Amendment VC288 took effect on 16 October 2025, eligible applications for two homes on a lot can use VicSmart, and so can a two-lot subdivision where a permit for up to two dwellings has been issued, has not expired and each lot will contain one dwelling. That subdivision class does not apply in the Low Density Residential Zone.

Can a granny flat be put on its own title?

In several places the rules say no. In NSW a lot with a secondary dwelling cannot be subdivided. In Victoria a permit must not be granted to create a separate lot for land containing a small second dwelling. In the ACT a secondary residence cannot be given a separate title or unit title, and in the NT an independent unit cannot get a separate title through a unit title scheme.

What is the difference between Torrens title and strata title for two homes?

A Torrens (green title) subdivision creates separate lots of land, each with its own title. Strata, community and unit title schemes divide a site into lots that can sit alongside common property. The options differ: SA allows Torrens or community title but no new strata, WA uses green title, survey-strata and built strata, and the ACT uses unit titling over one Crown lease.
