An occupation certificate certifies that the building or nominated part of the building is suitable and safe to be occupied. The occupation certificate must be obtained from the principal certifying authority (PCA) prior to the occupation of a new building or part of a building and also prior to commencing any change in the building's use.
Prior to issuing an occupation certificate, the PCA must be satisfied that the construction works satisfy certain legislative requirements and that the building or nominated part of the building is suitable for occupation. Key considerations are fire safety and the health, safety and amenity of future occupants of the building.
Despite receiving an occupation certificate there may be conditions of the development consent (such as providing car parking or landscaping the site) that need to be satisfied prior to occupying or using the building.
