How certification works in New South Wales

The certificates you'll hear about, and what each one actually does.

Complying Development Certificate (CDC)

A fast-track combined planning and building approval for projects that meet the State's pre-set standards, including many new homes, granny flats, pools and fit-outs. No DA, no council wait.

Construction Certificate (CC)

Issued after a Development Approval from council. Confirms the detailed construction drawings comply with the Building Code and the DA conditions, so building can start.

Principal Certifier

The certifier appointed before work starts, responsible for the critical-stage inspections through the build. That's us. One point of contact from footings to final.

Occupation Certificate (OC)

The final sign-off that the building is safe to occupy and matches the approval. Required before you move in, lease, or settle.

BCA consultancy

Design reviews, performance solutions and compliance reports for architects and developers who want issues found on paper, not on site.
