Chino Hills, CA Accessory Structures: Carport Rules (2026)

Carports in Chino Hills are treated as accessory structures governed by the Development Code (Title 16), Chapter 16.06 (General Development Standards). Unlike small storage sheds (up to 120 sq ft and 10 feet), carports are not included on the city's list of work exempt from a building permit, so a building permit is generally required before constructing one. Placement follows Section 16.06.070: accessory structures must be located outside the front, side, and rear setbacks, although a structure not exceeding 10 feet in height may be placed in the side or rear setback if it is set back at least 5 feet from the property line; the street-side setback for accessory structures is generally 10 feet. Because a carport that provides required covered parking can affect the home's parking compliance, and because design, height, and lot-coverage standards in Chapter 16.06 and the residential district standards (Chapter 16.10) apply, owners should confirm the exact requirements with the Community Development Department's Planning Division before building. The city's Building & Safety Division (909-364-2780) can confirm building-permit requirements for a specific carport project.
