Sedona, AZ Accessory Structures: Shed & Carport Rules (2026)

C. The floor area of any accessory structure cannot exceed 50 percent of the principal structure's floor area or 750 square feet, whichever is larger; the Director can waive that cap only for a structure used for animal or crop production tied to an agricultural use. Every accessory building must otherwise meet the same setback line as the house. The code carves out one exception for residential lots: a single accessory building that isn't used as habitable space and stays under 15 feet in height may come within five feet of the rear property line, provided it sits at least ten feet from the main house.

Only one accessory building on a lot may contain habitable space, and even that one is capped at a kitchenette unless a full kitchen is approved; every other accessory building on the property is barred from bathtubs, showers and any other habitable feature. Manufactured homes cannot be used as accessory buildings in any zoning district, and for single-family lots, any part of a building without an internal connection to the house, other than through a garage, carport, closet, bathroom or laundry room, counts as a separate accessory building subject to these same limits.

Owners planning a shed larger than these thresholds, or one closer to the property line than the standard setback allows, need administrative relief from the Community Development Department before building.
