After the effective date of this Chapter, it shall be the duty of the Administrative Officer to make a permanent record of all land uses and building uses which do not conform to the provisions of this Chapter. Any land use or building use which was not made a part of this record shall be considered an illegal use and is thus in violation of this Chapter and subject to provisions of Section 405.190. Appeals from this record may be made to the Board of Adjustment as provided in Section 405.120, Subsection (E).

After completion of a building or structure for which a building permit has been issued and all requirements of all codes and ordinances of the City have been met, a certificate of occupancy shall be issued by the Administrative Officer stating that the building or proposed use thereof complies with the provisions of this Chapter. The Administrative Officer shall keep a record of all certificates and copies shall be furnished upon request to any person having a proprietary or tenancy interest in the building affected. A building shall not be used nor land use shall not be made until a certificate of occupancy has been obtained from the Administrative Officer.
