Occupation certificate sequencing: what has to be finished, in what order
Why do occupation certificates get delayed, and how does a developer avoid it?
An occupation certificate is issued by the principal certifier once the building is complete and the certifier is satisfied that it complies with the development consent, the construction certificate and the building code, and it is the single most common point at which an apartment project runs late. The delay is rarely the building. It is the close-out: the consent conditions that have to be satisfied and documented, the fire safety certificate and the schedule of fire safety measures, the authority connections for power, water and sewer, the compliance declarations under the Design and Building Practitioners Act, and the certifier's own inspections. Each of these has a different party responsible and a different lead time, and they have to be sequenced from months out rather than gathered in the final fortnight. A developer should ask the builder for a close-out schedule at the start of the last quarter of the programme, listing every item, who owns it and when it will be done.
What the certifier needs
Evidence that every condition of consent has been satisfied, the fire safety certificate from the accredited practitioners, the compliance declarations lodged on the Planning Portal, the survey and as-built information, and its own final inspections.
The items with the longest lead
Authority connections and meters. Fire safety certification, which depends on the fire services being commissioned and tested. Consent conditions that require another authority's sign-off, such as roads, stormwater or a positive covenant. Each is started months before completion.
Interim versus final
An interim occupation certificate can allow occupation of part of a building while work continues elsewhere. It has its own requirements and is not a shortcut around the close-out.
The close-out schedule
A single list, owned by the builder, of every item standing between the building and the certificate, with the responsible party and the date. Reviewed weekly through the last quarter of the programme.

Related questions
Who appoints the certifier?
The person having benefit of the consent, usually the developer, though the builder manages the day-to-day relationship on a design and construct project.
Can settlements happen before the occupation certificate?
No. The certificate is the trigger for strata registration and settlement, which is why a late certificate costs developers money.
What about the strata plan?
Registration of the strata plan runs alongside the occupation certificate and depends on the surveyor and the titles office. It is on the same close-out schedule. Confirm the current requirements with your certifier.
