Chino Hills, CA Home Business: Zoning & Home Occupation Permits (2026)

040 for every home-based business operating in a Chino Hills single-family or multi-family neighborhood; there is no exemption for small or part-time businesses. 020 set the operating limits: the business cannot occupy more than twenty percent of the dwelling, or four hundred square feet, whichever is smaller, including storage in accessory structures, and none of that space can sit inside a required garage parking space. Only residents of the home may work on-site, no employees may report to the address, and there can be no exterior storage, display, signs, or banners visible from outside the unit.

Visitors and customers are capped at three per day, deliveries at three per day and limited to standard carriers like FedEx or UPS rather than commercial trucks, and the home cannot function as a retail storefront where customers browse merchandise, though occasional visits to complete paperwork, take payment, or pick up a pre-ordered product are allowed. A HOP business may keep one work vehicle at the home, no larger than 20 feet long, 8 feet tall, or 90 inches wide, parked in the garage or driveway, with a small identifying logo no larger than 18 by 12 inches per side panel.

035 flags categories the City considers incompatible with residential use outright and prohibits them from ever qualifying for a HOP, including auto-security installation, on-site carpentry or welding, veterinary boarding, massage practice, and vehicle storage or repair. 040 makes an approved HOP good for the lifetime of the business, so long as the required City business license is renewed annually.
