The PCA is usually the same person or organisation who issued the construction certificate  or complying development certificate for the development. You may choose either the Council's Building Certification Services  or an accredited certifier to be the PCA.

A PCA is the person responsible for ensuring that work during the construction process complies with the development consent, construction certificate or complying development certificate, the BCA and other applicable building regulations.

The PCA is also the only person who can issue the required occupation certificate.

In accordance with the requirements of the Home Building Act 1989 and Environmental Planning & Assessment Act 1979, for residential building work, the PCA must be provided with details of the licensed building contractor or owner-builder and a copy of any required home warranty insurance details.

A PCA cannot be replaced by another PCA on a development, except with the specific written consent of the previous and proposed PCA or the Building Professionals Board.
