Sec. 9-4.3001.  Conflicting licenses, permits, and certificates.
   All departments, officials and public employees vested with the duty or authority to issue permits, licenses, or certificates shall conform to the provisions of this chapter.  No such license, certificate, or permit, or the renewal or extension thereof, for uses, buildings, or purposes shall be issued where the same would be in conflict with the provisions of this chapter.  Any such license, permit, or certificate issued in conflict herewith shall be null and void.
   Whenever an ordinance which changes the zone classification of any property is adopted, no building permit shall be issued or renewed for any construction or improvement or other work which is not permitted by the new zone classification. If for any reason the ordinance does not become effective within the time prescribed by law, such restriction shall become null and void as to the subject property.
   Notwithstanding anything in this Code to the contrary, if the applicable use, height, area, or other zoning regulations are changed after the owner of property or a party of interest has lawfully started construction of a building or structure and has incurred obligations for work and material relating to such construction before the date of adoption of the zoning ordinance, and, as a result, such building or structure or use does not conform to the new zoning regulations, work on such building or structure or use may proceed as authorized in the building permit at any time within one year after the effective date of the change of zoning, but after that year such permit shall be null and void.  However, if substantial work on a building or structure above the foundations is done before the expiration of such one-year period, the proposed building or structure may be completed as authorized in the building permit within two (2) years after the effective date of the change of zoning, but after that time such permit shall be null and void.
