Subsection (c)(1) caps the total square footage of every accessory structure on a parcel, except swimming pools, at 50 percent of the primary dwelling's habitable floor area. Subsection (c)(2) further limits accessory structures, not counting patio covers, to no more than 30 percent of the required rear yard. Subsection (c)(4) requires accessory structures to be built in conjunction with or after the primary building, and (c)(3) lets the approving authority attach extra conditions on dwelling size, location, access or height where special circumstances threaten neighboring residences.
5-foot side street setback, 3 feet from interior and rear property lines, and 6 feet of separation from other buildings; the same size non-combustible structure has no side, interior or rear setback at all. A general accessory structure at or above 120 square feet or 8 feet tall follows the same combustible-shed setbacks. Front setbacks match the primary structure's required setback in the underlying zone, and no accessory structure may sit in front of the principal building.
