The occupation certificate must be obtained from the (PCA) prior to the occupation of a new building or part of a building and also prior to commencing any change in building's use.

Prior to issuing an occupation certificate, the PCA must be satisfied that the construction works satisfy certain legislative requirements, such as the BCA and that the building or nominated part of the building is suitable for occupation. Key considerations are structural adequacy, fire safety and the health, safety and amenity of future occupants of the building.
