A principal certifier must be appointed before building or subdivision works commence, when that work requires a construction certificate or a complying development certificate. The principal certifier will oversee the development’s construction phase and will complete the mandatory inspections to make sure that building standards are met. Once the building or subdivision work is complete, the principal certifier must complete the final inspections and will issue the final occupation certificate if all requirements have been satisfied.
