Principal Certifying Authority (PCA)

The Environmental Planning and Assessment Act 1979 requires a Principal Certifying Authority (PCA) to be appointed before building works commence on a development site.


At least two days’ written notice must be provided to Council and the PCA, before commencing building works.


A PCA may be a Private Accredited Certifier or a Council.


PCA signage must be installed on the development site. 


The PCA for the development is required to monitor the works throughout construction, including carrying out the mandatory critical stage inspections.


In situations where the works are not being carried out in accordance with the development consent or CDC, the PCA is required to issue a Notice of Intention to Serve an Order, so it is critical that works are carried out in accordance with the building approval. 


All mandatory critical stage inspections must be satisfactory to enable an Occupation Certificate to be issued at completion of works.
