An occupancy permit is generally required upon completion of building work undertaken in accordance with a building permit. The building permit will specify if an occupancy permit is not required, in which case a certificate of final inspection will be required.
The occupancy permit is evidence that a structure is suitable for use. The permit will specify conditions on the use of the structure, such as the maximum number of people it can accommodate, and safety measures that must be implemented.
Where a structure will be used for public entertainment, an occupancy permit certifying its suitability for that purpose must be obtained.
