To qualify as an allowable accessory building or structure, it must be maintained under the same ownership and on the same zoning lot as the principal building. All accessory buildings and structures shall conform to the applicable requirements of this title and to all other Village regulations, including, but not limited to, the Building Code, Electrical Code and the Fire Prevention Code.

G. No accessory building shall be used as a dwelling unit.
H. Permitted accessory buildings and structures and the development standards for each are indicated in table A of this section. These standards shall apply to all accessory buildings and structures, including those in existence at the time of adoption of this table.
