Occupation Certificate  
  Authorises the occupation and use of a new building or a change of building use for an existing building. An occupation certificate may be interim or final in nature, and may relate to a part or whole of a building. It cannot be issued until the Principal Certifying Authority is satisfied among other things, that the building is suitable for occupation or use in accordance with its classification under the Building Code of Australia. An occupation certificate must contain certain information relating to the health and safety of the occupants and is to be accompanied by the fire safety certificate and fire safety schedule for the building. Section 109M of the Environmental Planning and Assessment Act 1979 (NSW) provides that a person must not commence occupation of the whole or any part of a new building (which includes an altered portion of, or an extension to, an existing building) unless an occupation certificate has been issued in relation to the building or part.
