What “Building Practitioner (General)” actually means — and why it matters for class 2 buildings

The most common thing I get asked wrong is some version of “you are a licensed builder, so you can build the apartments.” In New South Wales that does not follow. A builder licence issued under the Home Building Act lets you contract for residential building work. Registration as a building practitioner under the Design and Building Practitioners Act 2020 is a separate registration, assessed separately, and on a regulated building it is the one that decides whether you can take the job at all.

What counts as a regulated building

Class 2, certain class 3, and class 9c — apartments, some residential care and accommodation, aged care — plus mixed-use buildings that contain them. From 1 July 2026 the framework also covers repair, alteration and renovation work on existing class 3 and 9c buildings, which pulled a large amount of refurbishment work into scope that used to sit outside it.

If your project has apartments above a retail tenancy, you are in the regulated regime whether the retail half interests you or not.

The categories are not decoration

Building practitioner registration is issued in classes, and the class is the claim. There is general, and there is general (low rise) and general (medium rise) — the last two carry real limits, roughly a 2,000 m² gross floor area cap and a storey cap respectively. There is a separate body corporate nominee set for practitioners who declare on behalf of a registered company rather than contracting themselves.

So “registered building practitioner” on its own tells a developer very little. The useful question is which class, because that is what determines whether the person in front of you can sign off the building you are actually constructing.

The one thing only this registration can do

Only a registered building practitioner can lodge a building compliance declaration. That declaration stands between a finished building and an occupation certificate. No declaration, no certificate, no settlement. Everything else in the regime is preparation for the moment somebody puts their own name on that document.

And that moment is not where the work starts

The sequence, in practice:

• Every regulated design has to be lodged on the NSW Planning Portal before construction commences. A registered design practitioner prepares them; the building practitioner lodges them with the design compliance declarations.
• A variation to a building element or a performance solution needs a new regulated design and a new declaration — lodged within one day of the variation.
• Before an occupation certificate, the building practitioner gives fourteen days’ written notice to the principal design practitioner, then lodges the building compliance declaration and the contractor document.
• Anything still outstanding goes in within ninety days of the occupation certificate issuing.

Read as a list of deadlines, that looks like administration. It is not. It is a requirement to build the documentation at the same time as the building, because a one-day variation window cannot be met retrospectively. On a job that is being documented properly you barely notice it. On a job that is not, the declaration is where it surfaces — months after the trades have gone, when the fix is expensive and the evidence is gone with them.

Why this matters if you are the one funding it

The declaration attaches to a named individual, and it does not expire when the job does. The statutory duty of care under the Act runs for up to ten years after completion. From 1 July 2026, registered building practitioners must carry professional indemnity insurance adequate for the work they do — and PI is written on a claims-made basis, so a lapse years later can open a gap over a building that was finished and handed over correctly.

Which means the useful question to ask a builder is not “are you licensed.” It is: which registered individual will sign the compliance declaration on this building, in which registration class, how many others are they signing this year, and will their PI still be in force in eight years’ time?

What changes next

The Building (Approvals and Practitioners) Act 2026 has passed and commences by proclamation once the supporting regulations are made. It repeals both the Design and Building Practitioners Act 2020 and the Building and Development Certifiers Act 2018, consolidating certifiers, engineers, designers and builders into a single registration framework.

Construction certificates become building approvals; occupation certificates become completion approvals. Only the owner can apply for a building approval — a builder cannot, unless they also own the property, which changes who holds the paperwork on a number of common delivery models. There is a new framework for prefabricated and modular construction, certifier penalties move from $33,000 to $1.1 million, and the statutory duty of care carries across substantially unchanged, extended to manufacturers and suppliers of prefabricated buildings.

The names change and the consolidation is genuinely useful. The direction of travel does not change at all: more accountability, attached to named individuals, for longer.

The practical version

None of this is a reason to be nervous about class 2. It is a reason to treat the documentation as part of the build rather than something that happens near the end. If the inspection and test plan is real, variations are captured as they happen, and one person has been across design compliance from the start, the declaration at the end is a formality. If not, it is the moment you find out.

Three things worth confirming before signing anything on a regulated building: that the individual signing is registered in a class that covers the building you are actually constructing; that the regulated designs go in before work starts rather than being caught up later; and that variations have a named owner and a one-day path to the Portal. None of those are difficult conditions. They are just far cheaper to set up at the start than to reconstruct at the end.
