A certificate of occupancy is required to occupy a commercial or industrial building on which building work has been carried out. The certificate certifies that the building is suitable for occupation and complies with the Regulations. This certificate is not required in respect of a residential building under the Building Code. An application must be accompanied by a written statement from the builder responsible for the building work that the building has been carried out in accordance with the relevant approval. A fee may be required on lodgement of an application.
