   A.   Applicability
   This part applies to uses that are customarily incidental and subordinate to a principal use of the same lot. Further this part also applies to any nonhabitable structure that is detached from a principal structure on the same lot that is incidental and subordinate in use and size to the principal structure and principal use of the same lot. Section 155.4302.B, General Standards for All Accessory Uses and Structures, establishes general standards that apply to all allowed accessory uses and structures. Section 155.4302.C, Abbreviations Used in Accessory Use/Structure District Tables, explains the abbreviations used in the tables showing whether a particular type of accessory use or structure is permitted or prohibited within the various zoning districts. Section 155.4303, Standards for Specific Accessory Uses and Structures, establishes a list of allowed accessory uses and structures, along with standards that apply to the accessory uses or structures regardless of the zoning district in which they are allowed or the review procedure by which they are approved, unless expressly stated to the contrary. These standards may be modified by other applicable requirements in this Code. If a use is determined to be an accessory use in a development, and the use is not established in Section 155.4303, Standards for Specific Accessory Uses and Structures, such accessory use shall be subject to the principal use standards in Article 4: Part 2, Principal Uses and Structures, as well as the standards in Section 155.4302.B, General Standards for AllAccessory Uses and Structures.
