         (b)   Subject to compliance with all of the requirements specified in the section or sections whose number appears in the "Special Conditions" column.
      (2)   The letter "S" in the zoning district column opposite the permitted use means the use is permitted in that zoning district only after:

         (b)   Subject to compliance with all of the requirements specified in the section or sections whose number appears in the "Special Conditions" column; and

The function and location requirements of the unlisted use must be consistent with the purpose and description of the zoning district, compatible with the permitted uses in the district, and be similar in traffic-generating capacity, noise, vibration, dust, odor, glare and heat producing characteristics.
   (D)   Accessory use. A use which is customarily incidental to that of the primary existing use, which is located on the same lot or premise as the primary existing use, and which has the same zoning district classification, shall be permitted as an accessory use without being separately listed as a permitted use subject to the determination of the Director of Planning.
