San Ramon, CA Fence Regulations: Height Limits (2026)

Fence height regulation in San Ramon is established in the Development Code (Title D) with standard residential limits familiar to California cities. Maximum fence heights without a building permit: 6 feet in side yards and rear yards, 3.5 feet (42 inches) in required front yard setbacks. The front yard limit applies from the front property line to the front building line of the main residence. On corner lots, an additional sight-distance triangle restriction applies at the intersection — typically 15 feet along each street frontage where fences must not exceed 3 feet to preserve driver visibility. Fences exceeding 6 feet require a building permit through the Building Division, with engineered plans often required for heights over 7 feet. The maximum permitted fence height even with a permit is generally 8 feet in rear yards; taller fences/walls require variance approval. Pool fences (safety barriers) have separate requirements (see swimming pool subcategory) and must be at least 60 inches. Decorative posts, pilasters, and trellises attached to fences may extend up to 1 foot above the base fence height without counting toward the fence height. Retaining walls integrated with fences: the combined height of retaining wall plus fence on top is regulated — typically fences may not exceed 6 feet above the higher of the two adjacent grades. Electric and barbed wire are prohibited in residential zones (see barbed wire subcategory). HOA CC&Rs in Dougherty Valley, Canyon Lakes, Twin Creeks, Crow Canyon Country Club, and other master-planned neighborhoods impose additional architectural requirements — approved fence materials, colors, and styles must match community design guidelines, and Architectural Review Committee approval is required before installation. California Civil Code §841 (Good Neighbor Fence Act) applies to boundary fences (see shared-fence subcategory). Permit fees for over-height fences typically range $200-400. Code Enforcement handles complaints about fences exceeding height; typical resolution is reduction to legal height within 60 days.
