Home/ How it works
The path from approval to keys
Three certificates stand between a piece of land and a family living on it. Council issues the first. Your Principal Certifier issues the next two — and both of those depend entirely on the quality of the documentation package put in front of them.
The three stages
Most homeowners think the hard part ends when the DA is approved. It doesn't — it changes shape.
Council has approved what you can build. Your approval comes with conditions — often dozens of them — that must be satisfied before construction can start.
Your Principal Certifier confirms the detailed design is consistent with the consent and complies with the National Construction Code. No CC, no lawful construction.
After critical stage inspections, your certifier confirms the building is suitable and safe to occupy. Missing paperwork here is the most common reason families can't move in.
Our working method
The same sequence every time, whether you're building one dwelling in Forestville or three in Frenchs Forest.
If your project meets the standards in the codes, a Complying Development Certificate can replace both the DA and the CC in one step — common for granny flats and straightforward alterations. And if you're creating separate titles, there's a whole separate certificate chain running alongside this one.
Once your CC is issued you still can't start. A Principal Certifier has to be appointed and notice given through the Planning Portal at least two days before work commences. We flag it in your schedule so nobody loses a week to it.
Critical stage inspections
For a typical house or dual occupancy (Class 1 and 10 buildings), your Principal Certifier must carry out mandatory inspections at set points. Miss one and the record can't be recreated afterwards — which is exactly how an OC ends up stuck.
| Stage | What is being checked | Where it bites later |
|---|---|---|
| Footings | Excavation and footing preparation before pouring | Structural sign-off at OC |
| Slab / reinforcement | Steel reinforcement in place before concrete is poured | Engineer's certification |
| Frame | Framing, including floor framing, before it is covered | Frame certificate for the OC pack |
| Wet area waterproofing | Membranes before tiling | Waterproofing certificate — a very common OC gap |
| Stormwater | Drainage installation before backfill | Works-as-executed drainage plan |
| Pool (if applicable) | Barrier and intent-to-fill | Pool certificate of compliance |
| Final | Completed building against consent, CC and the NCC | The OC itself |
Your certifier books and performs these. Our job is the paper trail around them — making sure each inspection is scheduled at the right moment and each resulting certificate lands in the OC package rather than in someone's inbox.
Common questions
Yes, for almost all building work. Development consent approves what you may build; a Construction Certificate confirms the detailed construction drawings and specifications are consistent with that consent and comply with the National Construction Code. Work generally cannot lawfully start without one, unless the work is exempt development, is covered by a Complying Development Certificate, or is certified Crown building work.
No — and we would be cautious of anyone who says they can do both. Certificates are issued by your council or a registered certifier, who must independently assess the project. We prepare and coordinate the documentation so that assessment is straightforward.
The certifier's assessment is usually the shorter part. The long pole is assembling the documents your conditions require — consultant reports, engineering details, compliance certificates. Projects that come to us with most documents already in hand move quickly; projects starting from the notice of determination take longer, and we'll give you an honest timeline in your assessment.
It depends on the size of the change. Minor variations can often be handled within the CC if the work remains consistent with the consent. Anything beyond that needs a Section 4.55 modification before the CC can be issued. We assess which side of the line you're on early, because discovering it late is expensive.
It's where we focus and where we know the council's conditions and habits best — Frenchs Forest, Forestville, Belrose, Balgowlah, Dee Why and surrounds. Talk to us about projects elsewhere in Sydney and we'll tell you honestly whether we're the right fit.
