Prior to the commencement of any building work, a Principal Certifier (PC) must be appointed by the landowner/s with the benefit of the Development Application (DA) or Complying Development Certificate (CDC) approval. In most cases the PC is a private accredited certifier, but it can also be Council. The persons with the benefit of the development consent (i.e. the landowner/s) choose who they wish to be the PC. Usually, the PC is the same certifier who issued the Construction Certificate (CC) or Complying Development Certificate (CDC). Council is to be notified in writing of who has been appointed as the PC (if it is not Council).
Any building work where a CC or a CDC is required to be obtained will also require a PC to be appointed. PCs are public officials and independent regulators of development. They are required to uphold the public interest. PCs are regulated through NSW Fair Trading, who provide a register of certifiers where the public can search for an accredited certifier.
NSW Fair Trading’s certifier register and more information about finding and appointing a certifier can be viewed on the NSW Fair Trading website.
Finding and appointing a certifier
From 01 July 2021, all PC appointments must be made using the NSW Planning Portal.
You must notify the PC and Council that you are planning on starting work. This is referred to as Notice of Commencement. This must be done at least two (2) days before any building work commences.
Additionally, you must also notify neighbours within 20 metres from the boundary of the development lot, prior to any demolition or construction works commencing.
