Full Breakdown
030 covers roofed detached accessory structures, garages, carports, barns, sheds, workshops, gazebos, and covered patios, as well as unroofed structures over 24 inches tall such as decks and trellises. A detached accessory structure ordinarily may only be built on a lot that already has a permitted main use it serves. The one exception: a lot without a main use may still carry a maximum of one detached accessory structure up to 120 square feet plus one more up to 576 square feet, so long as neither is plumbed or electrified.
040. Every accessory structure must otherwise meet the development standards, including setback and height limits, of the zone it sits in. j gives sheds a specific setback break: one shed under 120 square feet and under 12 feet in height is allowed to encroach into the required interior side and rear setback areas without needing a building permit at all, though it must still comply with applicable building and fire safety codes. Because Angels Camp is the only incorporated city in the county, this same Title 17 standard governs shed and accessory building placement everywhere else, from Copperopolis to Mokelumne Hill.
Violations & Fines
Accessory structures built without meeting these size, use, or setback standards are zoning violations enforceable under Title 17's enforcement chapter, which can require the structure be brought into compliance, relocated, or removed. Using a shed or other accessory structure as living quarters is expressly prohibited and is treated as a code compliance matter regardless of the structure's size or permit status.
