San Bernardino, CA Accessory Structures: Carport Rules (2026)

A carport is a permanent roofed structure providing vehicle shelter, typically open on two or more sides, and under the California Residential Code as adopted by San Bernardino it is not exempt from permits the way very small sheds are. The San Bernardino Development Code sets dimensional standards for carports based on zoning district. Front-yard setbacks generally require that covered parking structures sit at or behind the front building line of the primary dwelling, though zoning code may allow a driveway parking pad without a roof closer to the street. Side-yard setbacks are commonly three to five feet unless the carport is attached to the house, in which case side setbacks match the dwelling zoning. Height limits are typically 12 to 15 feet, matching accessory structure rules. Permits are required for any carport regardless of size, and engineered plans are required for wind and seismic loads per the California Building Code risk category. Prefabricated metal carports sold at home centers often do not include engineering and will fail plan check without an engineered letter specific to the site. Open carports do not count toward floor area for most zoning calculations but do count toward lot coverage. Enclosing a carport on three or more sides reclassifies it as a garage, which changes setback, fire-separation, and coverage rules. Carports may satisfy required off-street parking in most zones if dimensions meet the parking standard, typically 10 by 20 feet inside.
