Building certification is the process of engaging accredited certifiers to independently check and approve building works to ensure they comply with the safety, health, amenity and sustainability standards specified in legislation and building codes.
The main role of certifiers is to determine applications for Construction Certificates and Complying Development Certificates. Accredited certifiers may also be appointed as the Principal Certifier for the development. The Principal Certifier issues the Occupation Certificate at the completion of the development.
The Principal Certifier carries out critical stage inspections during construction to ensure the building work is in accordance with the development consent and legislative requirements.
At the completion of construction, the property owner must apply to the Principal Certifier for an Occupation Certificate. The Principal Certifier will conduct a final inspection and issue this certificate if they are satisfied that the building is suitable for occupation or use. A building must not be occupied or used without an Occupation Certificate.
