Avondale, AZ Accessory Structures: Carport Rules (2026)

Avondale regulates carports through its accessory building and off-street parking provisions rather than a dedicated carport ordinance. Section 28-133(d) addresses covered parking canopies, but only outside single-family residential districts: in all zoning districts except Single-Family Residential, covered parking canopies may be located within required side and rear setbacks unless a landscape buffer is required. In single-family neighborhoods, a carport is treated like other accessory structures, so it generally must meet the dwelling's required yards and the front-yard and height limits in Section 28-133, where buildings accessory to a residence are capped at 15 feet. A carport can serve as required parking only in limited situations: Section 28-164(h) lets a carport substitute for an enclosed garage for homes not originally built with a garage or in neighborhoods of carport homes; otherwise Section 28-164(a) requires an enclosed two-car garage. Parking spaces under a carport must still meet the 9.5-foot-by-20-foot minimum of Section 28-165(a). Because attached carports can affect setbacks and lot coverage, and because many Avondale subdivisions have HOA rules limiting carports, owners should confirm requirements with Avondale Development Services before building.
