Upon the request of the holder of a permit, the building official may issue a temporary certificate of occupancy for a building or structure, or part thereof, before the entire work covered by the permit shall have been completed; provided, that the portion or portions may be occupied safely prior to full completion of the building without endangering life or public health, safety, and welfare; and, provided further, that the agencies having jurisdiction over permits issued under other applicable codes are notified of the decision to issue a temporary certificate.
