That letter from Northern Beaches Council finally arrived: your Development Application has been approved. After months of waiting, it feels like the finish line.
Here's what surprises most homeowners: DA approval is not permission to build. It's permission to move to the next stage. Between today and the first day of construction sits a second approval process — and it's the one almost nobody warns you about.
Step 1: Read your conditions of consent — properly
Your DA approval comes with a schedule of conditions. Some apply before construction, some during, and some before you can move in. Buried in that list are usually several conditions marked "prior to the issue of a Construction Certificate" — things like detailed engineering plans, stormwater designs, landscape plans, waste management plans, or payment of council contributions. These aren't suggestions. Nothing moves forward until they're addressed, so reading them carefully on day one saves weeks later.
Step 2: Apply for your Construction Certificate
Where the DA approved what you can build, the CC confirms how you'll build it — that your detailed construction plans comply with the National Construction Code and every condition attached to your consent. The CC requires a much deeper documentation package than your DA did: construction-level drawings, structural engineering, specifications, BASIX commitments carried through into the plans, and evidence that each pre-CC condition has been satisfied. Assembling this package is where most post-DA delays actually happen. (We cover the full CC in detail here: Construction Certificate documentation explained.)
Step 3: Appoint your Principal Certifier
Before any work starts, you must appoint a Principal Certifier — the independent professional who inspects the build at critical stages and ultimately issues your Occupation Certificate at the end. One important rule: this is your appointment as the owner. Your builder cannot choose your certifier for you or steer you toward one — the certifier's independence is the whole point. (More on how to choose well.)
Step 4: Lodge your Notice of Commencement
With your CC issued and Principal Certifier appointed, there's one final formality: giving at least two days' written notice before work begins, via the Notice of Commencement on the NSW Planning Portal. Skip this and your build starts on the wrong side of compliance from day one.
Step 5: Break ground
Only now — DA approved, conditions addressed, CC issued, Principal Certifier appointed, notice lodged — can construction legally begin.
Where homeowners lose the most time
Across the Northern Beaches, the pattern is remarkably consistent. Homeowners assume the DA was the hard part, take a breather after approval, then discover the CC documentation package is a project in itself. Weeks slip by chasing engineers, matching plans against consent conditions, and re-lodging documents the Portal bounced back. The homeowners who move from DA approval to construction fastest all do one thing: they start the CC documentation the same week the DA is approved.
Read every condition. Assemble the CC pack. Lodge via the Portal. Appoint your certifier. Give notice. Build.
