Building approvals
and certification.

In Australia, getting a home approved is not one decision but a sequence of them. The word approval hides at least three distinct permissions: approval that the proposal is allowed on the land (the planning question), approval that the detailed design complies with the building rules (the building question), and, at the end, approval that the finished home may be occupied. Each is assessed against different criteria, often at a different time, and sometimes by a different body. A builder who treats them as a single tick will, sooner or later, be caught out by the one they thought they already had.

This reference sets out that pathway at the national level and names the common state variations as it goes. It is deliberately not a jurisdiction-by-jurisdiction rulebook, because the terminology, the thresholds and the process differ across the states and change over time, and a wrong specific is worse than a clear principle. Where a job needs the exact rule, it goes to the relevant state or territory planning and building authority. Everything here is general information, not legal or planning advice.

One word, two very different meanings

Before going further, one disambiguation. On this page approval means a statutory permission to build or to occupy. In the billing sense, an approval is a client signing off a progress claim, an entirely different process, and the difference between an approval to build and a finished home is the subject of the approvals versus completions guide. The two senses share a word and nothing else; this page is about the statutory kind.

The shape above holds across the country, but almost every label on it changes at a state border, and so do the thresholds for which pathway applies. The points below are the pattern, not the rule, and each carries a confirm-for-your-jurisdiction caveat.

• The names differ. NSW runs Development Applications, Complying Development Certificates, Construction Certificates and Occupation Certificates, with a principal certifier. Victoria runs planning permits, building permits and occupancy permits, with a registered building surveyor. Queensland, and every other state and territory, has its own equivalents again. The same job carries different paperwork depending on where it is.
• The fast-track pathways differ. Most states offer a streamlined route for straightforward proposals that meet pre-set standards (the Complying Development pathway in NSW is the well-known example), but what qualifies, and what it is called, is jurisdiction-specific. A proposal that is fast-tracked in one state may need full assessment in another.
• Who assesses what differs. The split between council assessment and private or accredited certification, and the titles of the people involved, is set by each state's system. Assuming the split you know applies everywhere is a way to appoint the wrong party or miss a step.
• The inspection regime differs. The mandatory hold points and who must attend them are set by the state, so the fixed dependencies in the programme are not identical from one jurisdiction to the next.

None of this is a reason to fear the process; it is a reason to confirm it per job. The reliable move is to establish, for the specific site and state, which approvals apply, which pathway the proposal qualifies for, and who signs each, before the programme and the price are committed.

The builders who rarely lose time to approvals treat the pathway as part of the job from the start. They confirm, for the specific site and state, which approvals apply and which pathway the proposal qualifies for before committing a start date. They appoint the certifier or building surveyor early and keep them supplied with the current documents, so an assessment is not held up waiting for a drawing. They read the conditions of consent and work them into the programme rather than discovering them later. And they hold the mandatory inspection hold points as fixed dependencies, sequencing the trades so nothing that has to be inspected is ever covered up first.

Above all, they carry approvals honestly on the schedule, as durations with their own risk, tied to the drawings and specifications they depend on. Approvals are assessed against the documented design, so a change to the design after approval can mean going back for an amended approval, which is why keeping the approved set and the built set aligned matters. The contract that sits over all of this, including who is responsible for obtaining which approval, is covered in the written building contract guide. The statutory specifics always go back to the relevant authority.

Development Application (DA) and development consent (the NSW planning approval), planning permit (the Victorian planning approval), Complying Development Certificate (a NSW fast-track combined approval for standard proposals), Construction Certificate (the NSW building approval) and building permit (the Victorian equivalent), Occupation Certificate and occupancy permit (the approval to occupy a finished home), principal certifier and registered building surveyor (the party who assesses the building approvals and inspections), hold point (a stage where work cannot proceed until an inspection passes), conditions of consent (the requirements attached to a planning approval). The wider vocabulary lives in the construction glossary.

The cluster spokes go deeper on the steps this hub introduces. In New South Wales the choice between a full development application and a fast-track complying development certificate is a decision in its own right, covered in DA vs CDC; the energy and sustainability requirements that sit inside design and approval are covered in BASIX and energy efficiency; and the final step, the approval to occupy the finished home, has its own deep reference in the occupation certificate. The other natural next reads are the critical path and dependencies for how approvals gate the programme, and the residential building contracts reference for how the contract allocates responsibility for obtaining them.
