Strata Subdivision

Feasibility
Noel Yaxley · FounderUpdated 1 October 2026

Strata subdivision divides a building into separately owned lots and shared common property under a registered strata plan, and in NSW the registration of that plan creates an owners corporation that the developer runs, funds and insures during the initial period, which ends once one third of the unit entitlements have sold.

Strata subdivision is the step that turns a finished building into lots you can actually sell, and in NSW it carries its own costs and obligations that begin before the first unit settles. The day the strata plan registers, the scheme exists: there is an owners corporation, the developer is acting as it, the building has to be insured, and the levies that fund the scheme fall on whoever owns the unsold lots, which at that point is the developer. This page sets out what registration triggers, what the developer carries during the initial period, what the first annual general meeting demands, how the Strata Building Bond and Inspections Scheme sits alongside it, how registration timing flows through to settlements, and how to carry all of it in a feasibility as dated cost lines rather than one allowance labelled legals. NSW is the worked context, because that is where the sources behind this page sit. Strata law there has been changing in stages since 2025, so confirm the current position before you rely on any of it.

This page is general information, not legal, tax or financial advice.

What is strata subdivision, and why does it matter to a feasibility?

In a strata scheme you own the inside of an individual lot, sometimes called the lot airspace, and share ownership of the common property with every other owner. The NSW Government's examples of common property include gardens, driveways and pools, and parts of the building itself such as external walls, roofs, stairwells, pipes and electrical wiring. The strata plan shows the unit entitlement for each lot, and unit entitlement sets three things at once: each owner's share of the common property, how much each owner pays to maintain it, and each owner's voting power in the owners corporation. A seller must include a copy of the strata plan in the contract of sale, and it is held by NSW Land Registry Services. For a developer the consequence is simple: a strata lot cannot be sold as a finished title until the plan exists and is registered, which puts strata subdivision on the critical path to revenue rather than after it. If you are still choosing between Torrens, strata and community title at site-screening stage, subdivision feasibility covers that choice; this page picks up once the answer is strata and the building is nearing completion.

When does the strata scheme actually start?

It starts at registration, not at the first sale. The NSW Government describes the developer or builder, known as the original owner, as acting as the owners corporation during the initial period, which starts when the strata plan is registered and ends when at least one third of the unit entitlements are sold. For that period the law limits what the original owner can do. According to the NSW Government, the original owner cannot change or cancel the by-laws or make extra by-laws that do not give a right or obligation to all owners or all lots, cannot alter common property except under a development contract, cannot incur a debt for more than is set aside in the owners corporation's funds to repay it, cannot borrow money or give securities, cannot appoint a strata managing agent or building manager to continue after the first annual general meeting, and cannot sell common property. The practical point is that from registration onward, decisions about the building are made under strata law, with limits that exist because the developer is sitting on both sides of the table. Plan the handover work, and any deals you want in place for the future owners, with those limits in mind.

Who pays the strata levies before the units sell?

Levies are paid by lot owners in proportion to unit entitlement, and on the day the plan registers the owner of every unsold lot is the developer. The owners corporation must, by law, keep an administrative fund for day-to-day expenses: maintaining common property, insurance, and recurrent costs such as electricity, water, waste removal, cleaning and garden maintenance. A budget has to be set so the owners corporation knows how much money the year ahead needs, and that budget determines the levies. So the first levies are funded by the developer, and they keep falling on every unsold lot until it settles. A building that registers and then takes months to sell through carries levies on its unsold stock for every one of those months, so model them as a monthly cost on unsold lots that steps down as settlements happen, the same way you would model interest on unsold stock. For a new multi-storey scheme, the NSW Government records that since 1 April 2026 the original owner must also engage an independent surveyor to review the initial levy estimates and certify that they meet the expected expenditure for the year ahead, based on expenses the original owner provides. A levy estimate set low to make units easier to sell will now be tested by someone who is not connected to the developer.

Does strata building insurance start at registration or at settlement?

Strata insurance is mandatory in NSW. The NSW Government lists what a scheme must have: building insurance, covering replacement or reinstatement of the building to as-new condition, the architects or other professionals needed to repair it and debris removal; public liability insurance, with a minimum of $20 million of cover; and work health and safety insurance, unless the scheme does not directly employ any workers and the complex is only used for residential purposes. Owners in a two-lot scheme may not need strata building insurance if the buildings on the two lots are physically detached, no building sits outside the two lots, and the owners corporation votes unanimously not to take it. Outside that exemption, the owners corporation exists from registration and the developer is acting as it through the initial period, so the cover has to be in place from registration, not from the first settlement, and the premium is paid through the administrative fund, which in the early months means through the levies the developer is paying on unsold lots. Ask your broker for a quote well before the expected registration date, and check with them how the construction-phase cover and the owners corporation's policy line up around handover and registration, so there is no gap.

What does the developer have to hand over at the first annual general meeting?

The original owner must hold the first annual general meeting within two months of the end of the initial period, with notice given to each owner, first mortgagee and covenant chargee on the strata roll at least 14 days before. If the original owner still holds half or more of the total unit entitlement at that meeting, the NSW Government records that its vote is reduced to one third of the total. At least 14 days before the meeting, the original owner must give the owners corporation a series of documents, one of which is the initial maintenance schedule: maintenance and inspection information for the parts of the common property, prepared on a standard form. Since 1 April 2026, the original owner of a multi-storey scheme, meaning three or more storeys above ground with lots one on top of another, must also have an independent surveyor certify that the schedule was prepared on the standard form and that the estimated contributions to the administrative fund and capital works fund meet the expected expenditure for the year ahead, and must deliver evidence of both at least 14 days before the meeting. The NSW Government defines an independent surveyor as someone not connected to the original owner who is either a Certified Quantity Surveyor with the Australian Institute of Quantity Surveyors or a Chartered Quantity Surveyor with the Royal Institution of Chartered Surveyors. Penalties of up to $11,000 for an individual and $55,000 for a corporation may apply to those multi-storey requirements, and the NSW Government lists a penalty of up to $11,000, plus $220 for each day, for not holding the first meeting on time or not giving owners the documents 14 days ahead. The owners corporation's 10-year capital works plan must then consider the schedule, so the document outlives the handover. For a feasibility, the schedule and the surveyor's certification are consultant fees with a deadline set by your sales rate, not by the construction programme.

How does the Strata Building Bond and Inspections Scheme fit in?

For new apartment building work, the Strata Building Bond and Inspections Scheme requires the developer to lodge a building bond with the Secretary before the occupation certificate is issued. The NSW Government sets the bond at 2% of the contract price, calculated on the total cost of all the contracts for constructing the building, or the percentage prescribed by regulation, and records that an increase from 2% to 3% has been deferred until 1 July 2028. The buildings covered can include carparks, common areas and commercial or retail space in a mixed-use building, and the scheme does not apply where the Home Building Compensation Fund does, so confirm which regime your building falls under. The timetable runs well past completion: the developer appoints a building inspector within 12 months of the building work finishing, an interim inspection and report follows between 15 and 18 months, a final inspection and report between 21 and 24 months, and the bond payment process should be completed between two and three years after the work finished. If there are no defects the bond goes back to the developer; if there are, it pays for rectification of the defects identified in the final report and any balance is returned. To show the scale, take an assumed total construction contract of $20,000,000, a figure chosen for this illustration rather than taken from any project: a 2% bond is $400,000, paid out before the occupation certificate and held for two to three years. That is a cash outflow, an inspector's fee and a delayed inflow, and it belongs alongside the defects liability period in the way you plan the tail of the project.

How does registration timing affect settlements and sunset dates?

For off-the-plan sales, the NSW Government notes that the date for completing the contract is not until the building is finished and the plan is registered, and that purchasers must be given a copy of the registered plan at least 21 days before settlement. Off-the-plan contracts commonly include a sunset clause requiring the plan to be registered, or an occupation certificate issued, by a set date, otherwise either party can rescind; a developer needs the buyer's consent, or an application to the NSW Supreme Court, to rescind using that clause, while buyers do not need court approval. Put together, a slip in registration pushes every settlement back by at least as long, and each month of slip is a month of interest, levies and insurance with no revenue behind it. Treat the registration date as a programme milestone with its own float, not as an administrative step after practical completion.

How should strata subdivision costs sit in a feasibility?

Give each strata cost its own dated line instead of folding it into legals. The survey and preparation of the strata plan and its registration, priced from your surveyor's and solicitor's quotes. Levies on unsold lots from the registration date, stepping down as lots settle. Building insurance, public liability and, where it applies, work health and safety cover from registration. The initial maintenance schedule and, for a multi-storey scheme, the independent surveyor's certification, timed to the first annual general meeting, which falls within two months of one third of the unit entitlements selling. For apartment buildings covered by the scheme rather than by the Home Building Compensation Fund, the strata building bond as an outflow before the occupation certificate and an inflow two to three years later, net of any rectification, plus the inspector's fees. Then test the deal on margin on cost with those lines in the model, and if the rest of the feasibility is not built yet, what a feasibility study covers sets out that logic in full. None of these costs is large enough on its own to sink a deal, but together they arrive at the one point in the programme where the project has spent almost everything and received almost nothing, and that is exactly where an undated allowance hides them.

Frequently asked questions

When does a strata scheme start in NSW?

At registration of the strata plan. The NSW Government describes the developer, known as the original owner, as acting as the owners corporation during the initial period, which starts when the strata plan is registered and ends when at least one third of the unit entitlements are sold. From that day the scheme needs insurance and funds, and the limits on what the original owner can do during the initial period apply.

Does the developer pay strata levies on unsold units?

Levies are paid by lot owners according to unit entitlement, and until a lot sells its owner is the developer, so the levies on unsold lots are a developer cost from registration until settlement. For new multi-storey schemes, the NSW Government records that since 1 April 2026 an independent surveyor must certify that the original owner's initial levy estimates meet the expected expenditure for the year after the first annual general meeting.

Is strata insurance compulsory for a new building?

Yes. The NSW Government states that strata insurance is mandatory in NSW: building insurance, public liability insurance with at least $20 million of cover, and work health and safety insurance unless the scheme employs no workers directly and is purely residential. Some two-lot schemes can opt out of strata building insurance by unanimous vote if their buildings are physically detached and none sits outside the two lots.

What is an initial maintenance schedule?

It is a document the original owner must prepare on a standard form and give to the owners corporation at least 14 days before the first annual general meeting, setting out maintenance and inspection information for the parts of the common property. For a multi-storey scheme, an independent quantity surveyor must also certify that it was prepared on the standard form, and the owners corporation's 10-year capital works plan must consider it.

How much is the strata building bond in NSW?

The NSW Government sets the bond at 2% of the contract price for new apartment building work, calculated on the total cost of all the contracts for constructing the building, and records that an increase to 3% has been deferred until 1 July 2028. It is lodged before the occupation certificate is issued and, after interim and final inspections, the payment process should be completed between two and three years after the building work finished. This is general information, not legal advice.

How UpScale Handles This

Strata costs are dated costs, so in UpScale's feasibility workflow they belong on their own rows in the Costs tab, part of the same six-tab structure — Land, Costs, Sales, Funding, Summary, Financials — rather than inside one legals allowance. The underlying appraisal engine runs a full Australian appraisal (monthly cashflow, S-curves, the GST margin scheme, NSW, VIC, QLD and WA duty, presales repaying debt, equity IRR, and solvers) computed identically across the web app, iOS and Postgres with a CI parity harness, so levies and insurance that start at registration, a bond paid before the occupation certificate, and settlements that wait on the registered plan sit in the months they actually fall.

Once a feasibility is approved it can be frozen as an immutable Original Budget, with a Baseline-vs-Delivery page that compares that frozen scenario, section by section, against the contracts you commit and map to each section in delivery.
