Maricopa, AZ Accessory Structures: Shed Rules (2026)

MCC 18.80.020 applies to roofed structures detached from and accessory to the main building, including sheds, workshops, arbors, gazebos, pergolas, garages, carports, and covered patios. Detached accessory buildings have a maximum height of 15 feet (attached ones cannot exceed the main building height). The minimum setback is 3 feet in any location other than the required front yard. Accessory structures must be located behind the front line of the primary structure unless otherwise specified, and on corner lots cannot project beyond the required front yard on any street frontage for lots under one acre. A detached accessory building may only be placed on a lot that already has a permitted main building. Residential accessory structures greater than 120 square feet require Planning and Zoning approval per the city's Residential Accessory Structures Guide. Detached accessory structures shall not occupy more than 30 percent of the required rear yard setback, and total roofed building coverage cannot exceed the zoning district limits. A detached shed shall not have plumbing for a kitchen or laundry unless approved as guest quarters. Always confirm specific district standards and the permit threshold with Development Services before building.
