San Jose, CA Fence Regulations: Fence Requirements (2026)

Under San Jose Municipal Code Title 20, fence height limits are zoned by location on the property. Fences and walls in the required front-yard setback (typically the first 20 feet from the front property line) are capped at 3 feet tall if solid, or 4 feet if at least 50% open (wrought iron, pickets with spacing). Side-yard and rear-yard fences are allowed up to 6 feet without a permit. Fences over 6 feet but under 7 feet may require design review depending on zoning. Any fence 7 feet or taller requires a building permit and engineered plans. Corner lots must maintain a sight-distance triangle at the intersection, generally a 15-foot by 15-foot area measured from the intersecting property lines where fences, landscaping, and solid objects must stay under 3 feet to preserve driver visibility. Fence materials are generally unrestricted in residential zones, but barbed wire, razor wire, and electrified fences are prohibited in residential areas. Property-line fences require mutual agreement with neighbors under CA Civil Code §841 (Good Neighbor Fence Act), which presumes shared cost and maintenance for enclosing fences. HOAs in Almaden, Evergreen, and Silver Creek often impose material and color restrictions that are stricter than city code.
