Alameda, CA Fence Regulations: Height Limits (2026)

The City of Alameda regulates fences as "barriers" under AMC Section 30-5.14 (Article XII, Development Regulations), which applies to fences, walls, and hedges including posts and framework. On residentially zoned or developed property, barriers in front yards may not exceed 3 feet, and barriers in side and rear yards may not exceed 6 feet (Sec. 30-5.14.c). On commercial and industrial parcels, barriers in required setbacks may reach 8 feet. In any visibility zone (a sight-triangle at corners, generally two 20-foot sides as determined by the City Engineer), no barrier may exceed 3 feet for traffic safety. The code permits height extensions with "see-through style" material (less than 50% opaque per square foot, such as pickets, lattice, or wrought iron): a 3-foot limit can rise to 4 feet, or to 5 feet subject to Planning Director approval for design compatibility; a 6-foot limit can rise to 8 feet. Barriers inside a permitted building envelope may rise to the zone's building height. Height is measured from grade within 18 inches horizontally of the point. These are city zoning rules and are stricter than the California Building Code, which only requires a permit above 7 feet and does not set front-yard limits.
