The Principal Certifier (PC) oversees the development’s construction phase and completes mandatory building inspections, known as critical stage inspections, to make sure that building standards are met. The PC is also responsible for processing any complaints about the development that may arise during the construction process.
Once building work has finished, the PC will complete inspections and may issue an occupation certificate if the building is deemed safe to occupy.
Before appointing a registered certifier:
- check that the certifier has the right class of registration for the work and read the conditions, if any, on their registration
- make sure their registration and insurance are current on the building certifiers public register
- look up the certifier’s name on the disciplinary register to see if any actions have been taken against them
- carefully read the contract for certification work.
Acceptance of appointment as Principal Certifier
The acceptance of the appointment of a PC will be issued on the NSW Planning Portal, including any supporting documentation. A sign with the contact details for the PC will also be displayed at the front of the building site.
Mandatory inspections
A Principal Certifier inspects a development at certain stages to ensure the works are consistent with the development consent and the National Construction Code.
Critical stage mandatory inspections for residential construction include:
- foundation after excavation and before footings are placed
- steel reinforcement in footings and subsequent floor slabs (excluding high rise)
- framework (excluding high rise)
- fire-protecting construction and openings in floors/walls
- wet area waterproofing of all bathrooms and laundries (only 10% in high rise)
- stormwater drainage connection
- swimming pool barrier fencing
- completed works (final inspection) to verify that the building is suitable for occupation.
Residential development will generally require 4 to 5 inspections.
