How to apply for a building permit (construction certificate) in NSW
In NSW, the equivalent of a building permit is a Construction Certificate (CC). You apply for a CC from either the local council or a private certifier (registered certifier) after obtaining development consent. The CC confirms the building plans comply with the Building Code of Australia (BCA) and relevant standards under the Environmental Planning and Assessment Act 1979 (NSW).
The framework
Environmental Planning and Assessment Act 1979 (NSW), Environmental Planning and Assessment Regulation 2021 (NSW), Building Code of Australia (National Construction Code), and the Design and Building Practitioners Act 2020 (NSW) for class 2 buildings.
The process
Obtain development consent first
A Construction Certificate cannot be issued until a Development Application (DA) has been approved or a Complying Development Certificate (CDC) issued. Confirm your consent conditions.
Choose a certifier
Appoint either the local council or a registered private certifier to assess and issue the CC. Private certifiers are often faster. Check the NSW Fair Trading register for registered certifiers.
Commission detailed construction plans
Engage an architect or building designer to prepare detailed construction drawings, structural engineering plans, and specifications that comply with the BCA and DA conditions.
Obtain specialist compliance reports
Obtain required reports such as BASIX certificate (energy and water efficiency), structural engineering certificate, access report (for commercial/multi-residential), and fire safety schedule if applicable.
Submit the CC application
Lodge the Construction Certificate application with your chosen certifier. Include all plans, specifications, structural certificates, BASIX certificate, and DA consent conditions.
Certifier assesses BCA compliance
The certifier reviews the plans for compliance with the BCA, Australian Standards, DA conditions, and any relevant legislation. They may request amendments or additional information.
Receive the Construction Certificate
Once satisfied, the certifier issues the CC. The CC must be obtained before any building work commences (other than demolition or excavation in some cases).
Appoint a Principal Certifier for inspections
A Principal Certifier (PC) must be appointed before work starts to carry out mandatory critical stage inspections during construction. The PC can be the council or a registered certifier.
Notify council and commence work
Give the council at least 2 days written notice before commencing building work. Ensure the builder holds a valid NSW contractor licence for work over $5,000.
Complete inspections and obtain Occupation Certificate
The Principal Certifier conducts critical stage inspections and, upon completion, issues an Occupation Certificate (OC). The building cannot be lawfully occupied until the OC is issued.
