Can You Subdivide Your Block in NSW? Torrens vs Strata, Explained

Building two dwellings on your land and being able to sell them separately are two different things. Plenty of owners discover this the hard way — the duplex is built, the buyer is ready, and then the title can’t be split the way they assumed. Subdivision is what turns one parcel into two saleable assets, and getting it right starts long before the slab goes down.

Here’s how subdivision works in NSW, the two title types, and the steps that decide whether you can actually split your block.

Why subdivide

For most owners the goal is simple: realise the value. A dual occupancy on a single title is worth one thing; two separate titles you can sell or finance independently are usually worth more. Subdivision lets you sell one dwelling and keep the other, sell both to different buyers, or simply create two distinct assets where there was one.

Torrens vs strata — the core decision

NSW has two ways to split a property, and the difference shapes everything from value to what you’re allowed to do.

Torrens title subdivision creates two separate freehold lots, each with its own title to the land. The owners hold their land outright, with no shared ownership and no body corporate. Buyers generally prefer it, and it usually commands a higher price — but it’s only available where the planning controls specifically permit it.

Strata title subdivision creates separate lots within a strata scheme, typically with some shared common property — a shared driveway, services, or building elements. It splits both land and air space, and it’s the common fallback where Torrens subdivision of a dual occupancy isn’t permitted.

The critical point: whether you can use Torrens or are limited to strata depends on the development, the site, and — for dual occupancies — whether the relevant Local Environmental Plan (LEP) allows Torrens subdivision of a dual occupancy at all. That answer changes from council to council.

Lot sizes — meet the minimum twice

If you’re building a dual occupancy with subdivision in mind, you generally have to satisfy lot size requirements at two points: the minimum lot size to build the dual occupancy, and the minimum size for each resulting lot once it’s split.

Those figures are set by each council’s LEP and vary widely. As a sense of the range, a number of Sydney LGAs sit around a 500 sqm minimum to build a dual occupancy and roughly 250 sqm per lot after subdivision — but precinct-specific controls, width and depth minimums, and DCP requirements can push that up. Some councils also impose width-at-the-building-line and minimum-depth controls on each child lot. The only reliable figure is the one for your specific lot, zone and council.

There are also nuances flowing from the recent housing reforms — for example, dual occupancies newly permitted in the R2 zone under the Housing SEPP aren’t automatically complying development under the older low-rise code. These distinctions affect both your build pathway and your subdivision options, so they’re worth pinning down early.

The approval steps

Subdivision is its own approval process, separate from the approval to build. In broad terms:

• Planning approval first. You need a planning approval for the subdivision — either a Subdivision DA through council or a Subdivision CDC through a certifier. This can often be lodged concurrently with the development that creates the two dwellings, so one application covers both building and subdividing. Doing this upfront saves time and lets you market the individual dwellings during construction.
• Build, then certify. The dwellings are constructed and you obtain the occupation certificate.
• Subdivision certificate. Only after the development is complete (and the relevant conditions are satisfied) is a Subdivision Certificate issued against the planning approval. A Subdivision CDC has its own requirements, separate from the Building CDC, and the Subdivision Certificate is separate again from the Occupation Certificate.
• Register the titles. The plan of subdivision is registered with NSW Land Registry Services, and the separate titles are created. For a Torrens split, each dwelling typically needs its own legal road access and driveway, and both dwellings must be built on the one lot before the lot can be divided into separate titles.

The trap that catches people

The most common — and most expensive — mistake is building a dual occupancy as “two dwellings on one lot” without ever structuring the project for the title outcome you want. Many duplexes have been approved and built this way, only for the owner to find, when they want to sell, that Torrens title was never actually achievable on that site or under that design.

Subdivision problems almost never appear at the end. They’re built in at concept stage — in the lot layout, the access arrangement, the setbacks, the title type assumed — and only surface later when someone needs titles created quickly. The fix is to decide the title structure first and design the development to deliver it.

CDC or DA for subdivision?

As with the build itself, some subdivisions can run as complying development (faster, via a certifier) while others require a DA to council. Which applies depends on the land, the zone, and the development type. A Section 10.7 planning certificate is a useful early check on what your land can and can’t do.

The bottom line

Subdivision is where a development project actually turns into value — but it’s a planning outcome you design for, not a step you bolt on at the end. Confirm the title type your site allows, check the lot sizes at both stages, and structure the approval (ideally concurrently with the build) before you commit. Get that sequence right and the titles follow cleanly.
