PCA (Principal Certifying Authority)
What a PCA is in NSW, what they certify (CC, OC, mandatory inspections), and where the role sits between Council and the builder under the EP&A Act.
Ask Chalkline about this →PCA, short for Principal Certifying Authority, is the registered certifier appointed by the property owner (or builder on their behalf) to issue critical approvals during a residential build in NSW. The PCA is appointed under the Environmental Planning and Assessment Act 1979 (NSW) and the role is distinct from the consent authority (usually Council) that approves the DA.
What the PCA does
- Issues the Construction Certificate (CC) confirming the design satisfies the BCA / NCC and the conditions of the DA, before any building work starts.
- Conducts mandatory critical-stage inspections at points set in the EP&A Regulation (e.g. footings, slab steel before pour, frame, wet-area waterproofing, final).
- Issues the Occupation Certificate (OC) at the end, confirming the work is fit to occupy.
Who can be a PCA
A PCA must be a registered certifier accredited by the NSW Building Commission (formerly the Building Professionals Board). The PCA can be private (a registered building surveyor) or Council. On most residential jobs the builder or owner appoints a private PCA before work starts.
