San Ramon, CA Fence Regulations: Material Restrictions (2026)

Fence material regulations in San Ramon balance the Development Code standards with extensive HOA architectural control. City rules permit most conventional fence materials in residential zones: dimensional lumber (cedar, redwood, pressure-treated pine), vinyl/PVC fencing, masonry (brick, block, stucco-finished), wrought iron and tubular steel, and chain link. Prohibited materials in residential zones include barbed wire, razor wire, concertina wire, electrified fences (except low-voltage pet containment), and fences incorporating broken glass, spikes, or similar hazardous features. Sight-obscuring fences in front yards over 3.5 feet are prohibited regardless of material. Retaining walls must use engineered materials meeting Building Code structural standards. In commercial and industrial zones including Bishop Ranch corporate campuses, additional decorative and architectural standards apply with Planning Division review. Design Review is required for fences visible from public streets in many zones. HOA CC&Rs in Dougherty Valley (Windemere, Gale Ranch), Canyon Lakes, Twin Creeks, and Crow Canyon Country Club typically specify exact approved fence systems — commonly a standard cedar good-neighbor fence in rear yards, wrought iron or tubular steel in front/visible locations, and prohibiting chain link entirely except in dog runs screened from view. Architectural Review Committee approval is required before construction with submission of material samples, dimensions, and setbacks. California Civil Code §714 (Solar Rights) preserves solar access rights — a fence that significantly shades a neighbor's existing solar system may be required to be trimmed or modified. Fence color restrictions in HOAs are enforceable. Enforcement: city Code Enforcement handles material prohibitions (e.g., homeowner-installed barbed wire), while HOA violations are addressed by HOA management and fine systems independent of city process. Boundary fence disputes involving material choice are governed by Civil Code §841 (see shared-fence subcategory).
