Your DA is approved.
Here's what your CC actually needs.

The day your Development Application is approved feels like the finish line. For most Northern Beaches homeowners it's the moment the paperwork actually begins — because a DA approves what you can build, and a Construction Certificate approves how you're going to build it. You need both before a single sod is turned.

What nobody hands you at approval is the list. Council sends a notice of determination with conditions attached, and somewhere inside those conditions sits every document your Construction Certificate will require. Nobody highlights them. Nobody sorts them. That job falls to you.

What a Construction Certificate actually is

A CC confirms that your construction plans and specifications are consistent with your development consent and comply with the National Construction Code. It's issued by your council or a registered certifier — never by council and your consultant, and never by us. Building work generally can't lawfully start without one, unless the work is exempt development, covered by a Complying Development Certificate, or certified Crown building work.

That word consistent is doing a lot of work. It's the reason a CC is refused far more often than people expect.

The document list, in the order it usually matters

1. Detailed construction drawings. Not the DA set. A construction set — dimensioned, coordinated, and referencing the approved scheme.
2. Specifications and finishes. What things are made of, to what standard.
3. Structural engineering. Drawings and certification from an engineer, matched to the soil classification.
4. Hydraulic and stormwater design. Where water goes, and proof it can get there.
5. BASIX certificate and evidence. Every committed measure has to be visible in the drawings and specification.
6. Conditioned consultant reports. Acoustic, arborist, geotechnical, bushfire, waste, traffic — whichever your conditions name.
7. Fees and levies. Long service levy and applicable council fees, paid before issue.

The four things that hold most packages up

1. Conditions nobody read closely

A notice of determination for a Northern Beaches dwelling can run past forty conditions. Buried among them are several that must be satisfied before the CC is issued — each with its own lead time, and each easy to miss on a first read. Found in week one, they're a schedule. Found in week nine, they're a delay.

2. Drawings that drifted

Between approval and construction documentation, a window moves, a floor level shifts, a room grows by 400mm. Individually harmless. Collectively, the construction set is no longer consistent with the consent — and your certifier can't issue. At that point you're looking at a Section 4.55 modification, which is its own application with its own timeline.

3. BASIX commitments that don't appear in the drawings

The certificate commits you to specific measures. If the drawings and specification don't visibly reflect every one of them, the package comes back. It's a paperwork failure, not a building one, and it's entirely preventable.

4. Reports that don't answer the condition

A consultant report can be technically excellent and still not respond to what the condition actually asked for. Reading the condition and the report side by side, before lodgement, is a ten-minute job that saves a three-week loop.

A complete package is a fast package. Certifiers aren't looking for reasons to say no — they're obliged to say no when something is missing.

One more thing after the CC

Getting the certificate issued still isn't the same as being allowed to start. You need a Principal Certifier appointed and notice given through the NSW Planning Portal at least two days before work commences. It's a small step that regularly costs people a week because it wasn't in anyone's schedule.

Where to start this week

Open your notice of determination and put every condition into one of three columns: before CC, during construction, before OC. Almost nobody does this, and almost everybody who does it finds at least one item they hadn't budgeted time for.

If you'd rather someone else did that first pass, it's the free assessment we offer — you send the consent, we send back the sorted list.
