You will require this certificate if you intend to occupy or use a new building or change the use of an existing building.
There are two types of occupation certificates:
- A final occupation certificate allows commencement of either the occupation or use of a new building (including alternations/extensions) or the new use of an existing building resulting from a change in its use; and
- An interim occupation certificate allows commencement of either the occupation or use of a partially completed building, or of a new use of part of an existing building resulting from a change of use of the building.
It is rare that an interim certificate is issued, but if one has been, a final occupation certificate is still required when all building work or the change of use is complete. A final occupation certificate revokes any occupation certificates issued earlier.
