You can Torrens title subdivide a duplex in NSW only where the council’s LEP allows the two resulting lots at that size, or where a state provision overrides the LEP minimum. Some LEPs contain a clause that lets an approved dual occupancy be split into lots smaller than the general minimum lot size; others do not, and the general minimum applies. Since 28 February 2025, sites in low and mid-rise housing areas near nominated town centres have a state non-refusal standard of 225 square metres and 6 metres width per lot. Everywhere else, if the numbers do not work, strata title is usually the only way to sell the two homes separately.
Key takeaways
- Torrens title subdivision creates two separate land parcels; strata title creates two lots within one scheme on one parcel, and councils treat them differently under the LEP.
- The LEP clause 4.1 minimum lot size applies to Torrens subdivision unless the LEP has a specific exception for dual occupancy lots.
- In low and mid-rise housing areas within 800 metres walking distance of nominated centres, the Housing SEPP non-refusal standard allows dual occupancy subdivision at 225 square metres and 6 metres width per lot in R1, R2 and R3 zones.
- A dual occupancy built as complying development can only be Torrens subdivided under the Code where the LEP already permits lots of that size.
- Subdivision needs its own consent, a subdivision certificate, a Sydney Water or Hunter Water section 73 certificate and registration of the plan with NSW Land Registry Services.
Torrens versus strata: what actually changes
Both forms give each home its own saleable title, but the planning rules treat them differently.
| Feature | Torrens title | Strata title |
|---|---|---|
| What each owner holds | A separate lot of land with the building on it | A lot within a strata scheme plus a share of common property |
| LEP minimum lot size (clause 4.1) | Applies unless an exception clause exists | Generally does not apply to strata lots, although some LEPs add a strata clause |
| Ongoing body corporate | None | Owners corporation, levies, by laws |
| Shared services | Each lot needs its own water, sewer and stormwater connections or easements | Shared services sit on common property |
| Market perception | Usually preferred by buyers | Accepted, sometimes discounted |
Step one: find the minimum lot size on the LEP map
Every Standard Instrument LEP has a Lot Size Map and a clause 4.1 that says a lot created by subdivision must be at least the size shown on the map. In much of Blacktown, Penrith and Liverpool the R2 figure is 450 square metres; in parts of the Hills and Hawkesbury it is larger; in Growth Centre precincts such as Marsden Park, Schofields and Austral the minimum is often smaller and set by the precinct plan under State Environmental Planning Policy (Precincts, Western Parkland City) 2021. A 600 square metre lot with a 450 square metre minimum cannot be Torrens subdivided under clause 4.1 alone because each new lot would be 300 square metres.
The section 10.7(2) planning certificate confirms the LEP and zone, and the LEP lot size map shows the figure. Check both, because lot size boundaries sometimes run through a single street.
Step two: look for a dual occupancy exception clause
This is where councils differ, and it is the reason the same duplex can be split in one LGA and not in the next. A number of LEPs include an additional clause, often numbered 4.1A, 4.1AA or 4.1B, that allows subdivision of an approved dual occupancy into lots below the general minimum, provided each dwelling sits wholly on its own lot and the lots meet a smaller figure. Others allow it only for attached dual occupancies, only in certain zones, or only on corner lots. Some LEPs have no exception at all, so the general minimum stands.
Because the wording and numbers vary, we do not quote figures for individual councils here. Read the current LEP for the site in full, including any local clause about dual occupancies. If the clause exists, apply for the dual occupancy and the Torrens subdivision together so the consent covers both.
Step three: check whether the state non-refusal standard applies
Stage 2 of the NSW Government’s Low and Mid-Rise Housing Policy commenced on 28 February 2025. For dual occupancies on land in a low and mid-rise housing area, meaning residential land within 800 metres walking distance of a nominated town centre or station in the Six Cities Region, the Housing SEPP sets non-discretionary standards that a council cannot use as a reason for refusal. For subdivision in the R1, R2 and R3 zones the standard is a minimum of 225 square metres and 6 metres width per lot. That is a material change for sites in places like Blacktown, Seven Hills, Penrith, Liverpool, Campbelltown, Gosford and Wollongong that fall inside the mapped areas.
Three qualifications. The site must actually be in the mapped area, confirmed through the legislation and the department’s map rather than a radius. The policy excludes heritage items, bushfire prone land, flood planning areas in certain councils and the whole of the Hawkesbury, Blue Mountains, Wollondilly and Bathurst LGAs. And the standard removes lot size as a reason for refusal; it does not remove merit assessment of the design.
What happens when the numbers do not work
If the lot is outside a low and mid-rise housing area, the LEP has no exception clause and the general minimum cannot be met, the honest answer is that Torrens subdivision is not available. The options are:
- Strata subdivision. Available for most dual occupancies once built, subject to the LEP and DCP. Buyers accept it, and for attached pairs it is the normal outcome across much of Sydney.
- A Clause 4.6 request. Clause 4.1 is a development standard, so a written request to vary it is possible in a DA. Councils are cautious about lot size variations, and a request must show that compliance is unreasonable or unnecessary in the circumstances and that there are sufficient environmental planning grounds. A small shortfall on a site that otherwise meets every objective can succeed; a 30 per cent shortfall rarely does. We prepare these as part of our Clause 4.6 variation request service and will tell you frankly when the case is weak.
A dual occupancy approved as complying development under the Low Rise Housing Diversity Code can also be subdivided under the Code, but only where the LEP already permits lots of that size. The Code does not override clause 4.1.
The paperwork after consent
Consent is the start of the subdivision, not the end. A Torrens subdivision of a duplex typically needs:
- Compliance with the subdivision conditions, usually separate services to each lot and any drainage or access easements created by a section 88B instrument.
- A section 73 compliance certificate from Sydney Water or Hunter Water, which may involve sewer extension or a building over sewer approval. Sydney Water publishes the process for developers.
- A registered surveyor preparing the plan of subdivision with the party wall shown correctly for attached dwellings.
- A subdivision certificate from council or an accredited certifier, confirming the conditions are met.
- Lodgement and registration of the plan with NSW Land Registry Services, at which point the two new titles exist.
On attached pairs the plan must define the boundary through the party wall and create the rights each owner needs to maintain their half.
Frequently asked questions
Can I subdivide a duplex into two Torrens titles in NSW?
Only if each resulting lot meets the LEP minimum lot size, or the LEP has a specific clause allowing smaller lots for an approved dual occupancy, or the site is in a low and mid-rise housing area where the 225 square metre and 6 metre non-refusal standard applies. Otherwise strata title is the usual alternative.
What is the minimum lot size to subdivide a dual occupancy in Sydney?
It varies by council and by the LEP lot size map. Many R2 areas have a general minimum of 450 square metres or more, and some LEPs allow smaller lots for dual occupancies. In low and mid-rise housing areas near nominated centres the state standard is 225 square metres per lot with 6 metres of width.
Do I need to apply for subdivision at the same time as the duplex DA?
It is strongly recommended. Applying together means the consent covers both and the conditions for services and easements are set at the start. Adding subdivision later requires a new DA or a section 4.55 modification, and a later application can be refused if the lot size rules do not support it.
URBA checks the lot size clause, the exception provisions and the state standards before a subdivision DA is drawn, and prepares the SEE and any Clause 4.6 request through our subdivision planning service across Sydney, the Central Coast and the Hunter.
