Chino Hills, CA Fence Regulations: Height Limits (2026)

Fence and wall heights inside the incorporated City of Chino Hills are governed by the city's own Development Code (Title 16, Chapter 16.06, Section 16.06.120, Fences, walls and hedges), not San Bernardino County's code and not the neighboring City of Chino. For single-family residential lots, the maximum height is 4 feet in the required front yard and 6 feet in the required side and rear yards. A 6-foot fence or wall is permitted in the front yard only on the condition that the portion projecting above 3 feet (excluding pilasters) is an open material such as tubular steel or a transparent material such as acrylic. Hedges within the required front yard may not exceed 4 feet, while hedges elsewhere have no maximum. The overall height is measured from the highest point of the wall or fence to the lowest grade within the property boundaries, and fence posts may extend a maximum of 4 inches above the fence. These city zoning limits are stricter than the state building-permit threshold: the California Building/Residential Code exempts fences not over 6 feet from a building permit, but Chino Hills caps front-yard heights at 4 feet by right. Corner-lot sight visibility rules under Section 16.06.080 also restrict what may be placed in clear-corner areas.
