No vacant land shall be used or occupied for other than an approved use in the zoning district in which it is located and no building hereafter moved into or relocated within the City shall be so occupied or used until a certificate of occupancy shall have been issued by the Building Inspector. Such certificate shall show that the building or land or part thereof and the proposed use thereof are in conformity with the provisions of this chapter. Such certificate shall be issued only when the building or land and the proposed use thereof conform with all the requirements of this chapter. No such certificate shall be required for any property for which a valid zoning permit providing for such use or occupancy exists.

Application for such certificate shall be made to the Building Inspector, in writing, on such form and containing such information as the applicant deems sufficient to advise such Inspector of his request. After reviewing such application, the Inspector may require such additional information as he deems necessary.

The Board of Zoning Appeals is hereby authorized to hear and rule on appeals from the denial of such certificates by the Building Inspector and, upon such terms and with such conditions as it deems proper, may authorize the Building Inspector to issue a temporary certificate for a limited period of time.

The fee for a certificate of occupancy shall be established by the Common Council from time to time.
