§ 156.066 PRINCIPAL USES.
   (A)   A principal use may be authorized as either a permitted use or a special exception. Permitted uses are those uses which are allowed without special permission of the Board of Zoning Appeals, given that they follow the provisions set forth in this chapter. Special exceptions are only permitted following a public hearing and approval by the Board of Zoning Appeals, as per §§ 156.085 through 156.093.
   (B)   Principal uses for each district are listed with their provisions under the district headings in §§ 156.120 through 156.126, 156.140 through 156.144, and 156.155 through 156.157. A quick reference is available in the form of a use matrix; however, because some principal uses may contain special provisions in some districts, §§ 156.120 through 156.126, 156.140 through 156.144, and 156.155 through 156.157 shall be considered the definitive listing of principal uses and their regulations.
   (C)   In any district, no more than one principal structure and one principal use shall be located on a single lot; except that primary structures designed and platted as a single unit under single ownership and control, such as a multifamily residential project, business shopping center, or combined industrial operations, may be permissible on a single lot under the terms of this chapter.
   (D)   Any preexisting legal use that continues in a district where it is not currently authorized is subject to all of the zoning ordinance provisions for that use in the areas where that use is authorized.
