Except in the A Agricultural District, the C-1 Central Business District and the I-2 Heavy Industrial District, or as otherwise provided by this chapter, a separate ground area called the "zone lot" shall be designated, provided and maintained for each structure containing a permitted use or uses. Each zone lot shall have at least one front line and shall be occupied only by a main structure containing the permitted use or uses and a subordinate structure or structures containing only accessory uses. Designated zone lots in the A, C-1 and I-2 Districts may contain more than one main structure containing a permitted use or uses.

A zone lot shall consist of a single parcel of contiguous land and shall be designated as a zone lot only by the owner thereof. Where a designated zone lot is not owned by a single individual or entity or where the ownership of a structure to be placed on the zone lot is different from the ownership of the land, all responsible parties shall agree and participate in the designation of the zone lot. A record of the designation of zone lots shall be kept in the files of the Zoning Administrator.

No zone lot shall be designated unless it shall conform to all of the applicable regulations of the zoning district in which the property is located.

The land area occupied by a use and/or the building site designated and occupied by each structure on the effective date of this regulation shall be deemed the zone lot for such use and/or structures. Upon application to and approval by the Zoning Administrator, the boundaries and area of the zone lot may be amended, provided full compliance can be maintained with all of the requirements of this chapter.

A zone lot may or may not conform to the numbered and designated lots on a duly recorded plat.[1]
