Chino, CA Accessory Structures: Carport Rules (2026)

Carports are open-sided roofed structures used to shelter vehicles and are treated as accessory buildings under Chino Municipal Code Title 20 (Zoning). A building permit is required under CMC Title 15 because California Residential Code R105.2 only exempts one-story detached accessory structures used as tool/storage sheds, playhouses, and similar non-vehicle uses up to 120 sq ft; carports do not qualify for that exemption. Detached carports in R-1 zones generally must observe a 5 ft side and 5 ft rear setback (verify specific zone in Title 20), may not exceed accessory-structure height limits (typically 14 ft to top of plate for accessory buildings), and count toward lot coverage. Attached carports must meet the principal-dwelling setbacks (typically larger front/side). If the parcel is in an R-1 or R-2 zone with a required covered-parking standard, converting a garage to a carport may not satisfy the covered parking requirement unless the property includes other compliant covered parking. Under state ADU law (Gov. Code §65852.2 / §66310 et seq.), if a carport is demolished to build an ADU, replacement parking is not required.
