District boundaries indicated as approximately following the centerlines of streams, rivers or other bodies of water shall be construed to follow centerlines, and in the event of change in the location of streams, rivers and other bodies of water, shall be construed as moving with the actual body of water and following the centerline.
Distances not specifically indicated on the Official Zoning District Map shall be determined by the scale of the map.
The following regulations shall apply in all zoning districts:
In the S-C, R-C, R-1, R-2, R-3 and R-4 Districts, any use not specifically listed as an authorized use in the zoning district shall not be permitted in that zoning district.
In the B-1, B-2 and M-1 Districts, any use not specifically listed in the authorized uses for the zoning district shall not be permitted in that zoning district, unless such use is authorized by the Zoning Hearing Board as a use by special exception in accordance with the applicable express standards and criteria for "Comparable Uses Not Specifically Listed" specified in § 1403.12 of this chapter.
In all zoning districts where single-family dwellings or two-family dwellings are an authorized use or are a legally nonconforming use, the single-family dwelling or two-family dwelling shall be the only principal structure on the lot.
In all zoning districts where authorized by this chapter, two or more multifamily dwellings may occupy the same lot; two or more nonresidential buildings may occupy the same lot; and two or more nonresidential uses may occupy the same building, provided, in all cases, that all applicable requirements for each of the structures or uses can be met on the lot.
In all zoning districts, all accessory structures shall be located on the same lot with the principal structure to which they are accessory. Any accessory structure shall not be built unless or until the principal structure it serves exists on the lot.
