(a) When not accessory. A structure located within three feet of a principal structure and a structure connected to a principal structure by an enclosed breezeway less than 15 feet long is part of the principal structure and is not an accessory structure.
(b) In front yard. Access ramps to accommodate a person under disability, driveways, paved or gravel at-grade surfaces, fences, noise barriers or noise walls, signs, walkways eight inches or less above grade, and walls may be located in the front yard. When a new principal structure is constructed in an RA or RLD District, an existing barn may be retained in the front yard. Otherwise, an accessory structure may not be located in the front yard of a nonwaterfront lot.
(c) On a different lot. An accessory structure or use may not be located on a lot other than the lot on which a principal structure is located, except that:
(1) a fence may be located on a lot without a principal structure;
(2) a private residential pier to serve a lot with a principal structure may be located on land owned by a homeowner's association that abuts the mean high-water line if an agreement is recorded among the land records that allows location and use of the pier on the land owned by the homeowner's association; and
(3) an accessory structure may be located on an unimproved lot abutting a lot improved by a principal structure, provided the lots are under common identical ownership and the accessory structure serves the lot with the principal structure for the exclusive use of the owner or the principal structure on the abutting lot. The Office of Planning and Zoning may require that a structure built pursuant to this subsection be removed as a condition of issuance of a building permit in the event a principal structure is to be constructed on the same lot as the accessory structure.
(d) Floor area. The floor area of an accessory structure, including an accessory structure constructed pursuant to subsection (c)(3), may not be greater than the floor area of the principal structure.
(e) Right-of-way setback. An accessory structure may not be located in a setback from a right- of-way line.
