El Monte, CA Fence Regulations: Height Limits (2026)

120, Walls, Fences and Hedges, breaks residential fence and wall heights down by location on the lot. In the front yard, or within five feet of a street-side yard, solid fences, walls and hedges cap at 4 feet, though a 5-foot fence is allowed if it's at least 50 percent open and built of decorative wrought iron with decorative block pilasters. Corner lots carry a stricter limit inside the corner visibility triangle, the area measured 20 feet along both property-frontage lines from the intersection at the curb or pavement edge: solid fencing there caps at 42 inches, with the same 50-percent-open wrought-iron exception allowing up to 4 feet.

Everywhere else on a residential lot, fences and walls can reach 6 feet. Residential developments with three or more dwellings must install and maintain a 6-foot masonry wall along their rear and interior side property lines. Nonresidential uses in residential zoning districts follow the same front-yard rule but must build a masonry wall at least 6 feet and no more than 8 feet high along rear and interior side lines abutting a residential district or use; nonresidential zoning districts cap street-yard fences at 5 feet, require the same 6-to-8-foot masonry wall where abutting residential property, and allow up to 8 feet everywhere else, with industrial uses able to get 14-foot decorative masonry screening walls through Design Review if set back 35 feet from any street.

Grade-separating walls follow separate rules in subsection E: where the developed lot sits below an adjacent property, the wall tops out at 6 feet above that neighbor's grade; where it sits above, the cap is 8 feet if adjacent to residential and 10 feet otherwise.
