   9.   Area Regulations. No building or structure, or part thereof, shall hereafter be built or moved or remodeled, and no building, structure, or land shall hereafter be used, occupied, or designed for use or occupancy so as to provide any setback or front, side, or rear yard that is less than that specified for the zoning district in which such district or use of land is located or maintained.

   10.   Street Frontage Required. Except as permitted in this chapter, no lot shall contain any building used in whole or in part for residence purposes unless such lot abuts for at least 40 feet on at least one street, or unless it has an exclusive unobstructed private easement of access or be not more than one single-family dwelling for such frontage or easement, except that a common easement of access at least 24 feet wide may be provided for two or more such single-family dwellings or for one or more two-family or multiple dwellings.

No part of a yard, acreage, or other open space provided about any building or structure for the purpose of complying with the provisions of this chapter shall be included as part of a yard, acreage, or other open space required under this chapter for another building or structure. Off-street parking and loading areas may occupy all or part of any required yard or open space except as otherwise specified in this chapter.

   14.   Approved Plats. Whenever the plat of a land subdivision on record in the office of the County Recorder shows a setback building line along any frontage for the purpose of creating a front yard or side street yard line, the building line thus shown shall apply along such frontage in place of any other yard line required in this chapter unless specific yard requirements in this chapter require a greater setback.

   15.   Pending Applications For Building Permits.
