(A)   Conformity required. Buildings or structures shall not be erected, constructed, used, reconstructed, altered or maintained; and any lot or land shall not be used or maintained; and a new use shall not be made of any building, structure or land, except in conformity with the provisions of this chapter.
   (B)   Unlawful building. Any building that is used, erected, occupied or altered contrary to the provisions of this chapter shall be deemed an unlawful structure and a nuisance and may be required to be vacated, torn down or abated by any legal means, and shall not be used or occupied until it has been made to conform to the provisions of this chapter. Public expenditures toward abating such nuisance shall become a lien upon the land.
   (C)   Required space. Any space used for a required setback, open space or lot area for a building may not be counted or calculated to meet the same requirements for any other building.
   (D)   Frontage. No principal building shall be erected on a lot, unless that lot fronts, as required by § 153.140, upon an improved street or access road. Multiple-family, commercial, office, industrial, or other developments may be exempt from this requirement, as provided in § 153.140.
   (E)   One lot, one building. A lot or parcel shall not be devoted to more than one principal use, or contain more than one principal building, except for properties in the CBD District and groups of multiple-family dwellings, commercial buildings or industrial buildings determined by the Zoning Administrator to be a principal use collectively, based on meeting all of the following criteria:
      (1)   Individual buildings share common parking areas, signs, access and similar features;
      (2)   Buildings are under single ownership;
      (3)   Individual activities support one another (such as vehicle sales/vehicle repair or gas station/restaurant/ convenience store); and
      (4)   Buildings are architecturally unified and compatible.
