A certificate of occupancy shall be required for any of the following:

1. Occupancy and use of any building or portion thereof hereafter erected or altered;
2. Change in use of an existing building to a use of a different classification;
3. Occupancy and use of vacant land, or change in the use of land to a use of a different classification; and
4. Any change in use or extension of a nonconforming use. This certificate shall indicate that the proposed use of such building or land is in conformity with the provisions of this Chapter.

A certificate of occupancy shall be granted or refused within 10 days after the Zoning Officer has been notified of the completion of the authorized construction or alteration, or, where no construction or alteration is involved, within 10 days after receipt of written application therefor. Upon written request from the owner, the Zoning Officer shall issue a certificate of occupancy for any building or land existing at the time of enactment of this Chapter, certifying, after inspection, the extent and kind of use or disposition of the buildings or land, and whether such use or disposition conforms with the provisions of this Chapter. Pending completion of a building or of alterations thereto, a temporary certificate of occupancy may be issued by the Zoning Officer, for the use of a part or all of the building, provided that such temporary occupancy or use would not tend in any way to jeopardize life or property. A record of all certificates of occupancy shall be kept on file in an office of the Borough, and a copy of any such permit shall be furnished upon request to any person having a proprietary or tenancy interest in the building or premises.
