Construction Certificates
A Construction Certificate confirms that the detailed construction documentation is consistent with the development consent and complies with the Building Code of Australia. It must be obtained before any building work begins.
Overview
Where a project is approved by development application, a Construction Certificate is the bridge between consent and commencement. It verifies that the construction-stage drawings, specifications and engineering details give effect to the consent and meet the National Construction Code.
Assessment is undertaken in accordance with the Environmental Planning and Assessment Act 1979 and the Environmental Planning and Assessment (Development Certification and Fire Safety) Regulation 2021. The certifier checks that conditions of consent required to be satisfied before a CC have been addressed, and that the documentation is adequate for the work proposed.
For class 2, 3 and 9c buildings, the Design and Building Practitioners Act 2020 requires regulated designs and compliance declarations to be lodged on the NSW Planning Portal before a Construction Certificate can be issued.

Common issues and delays
Plans inconsistent with consent
Construction drawings that depart from the approved DA cannot be certified until reconciled or a modification is obtained.
Unsatisfied pre-CC conditions
Many consents carry conditions that must be met before a CC issues; overlooking them is the most common cause of delay.
Missing DBP declarations
For applicable building classes, the absence of lodged regulated designs and declarations prevents issue.
Incomplete engineering
Structural details that are not yet certified hold up assessment.
Frequently asked
When do I need a Construction Certificate?
After a development application is approved and before any building work begins. The CC confirms the construction documents give effect to the consent and comply with the Building Code of Australia.
What is the difference between a CC and a CDC?
A Construction Certificate follows a merit-based development consent and covers construction detail only. A Complying Development Certificate combines planning and construction approval in one code-based certificate.
Do I need design declarations for my project?
For class 2, 3 and 9c buildings, the Design and Building Practitioners Act 2020 requires regulated designs and compliance declarations on the NSW Planning Portal before a CC can issue. We confirm what your building class requires.
