Santa Ana, CA Fence Regulations: Fence Permit Requirements (2026)

Section 41-610 of the zoning code governs walls and fences citywide, and subsection (b) sets the permit trigger for residential front yards: in the RE, R1, R2, R3, and R4 zones, and any residential use in a specific development district other than SD No. 19, no front yard fence taller than 18 inches can go up without a permit from the planning and building agency. The city must issue the permit if the fence meets the section's design rules. Materials are limited to wood, wrought iron, tubular steel, stone, brick, stucco, or decorative block such as slump stone or split-faced block, other materials, including plain chain link, are not approved for a front yard fence under this subsection.

Spikes, stakes, or other sharp metal objects are prohibited outright, and decorative arbors placed in the required front yard or landscaped area are limited to walkway locations only, capped at 10 feet high, 6 feet wide, and 3 feet deep. Subsection (a) caps front yard fence height at 4 feet on arterial streets and 3 feet on all other streets, measured from the curb or established grade, while side and rear fences elsewhere on the lot may reach 8 feet. Subsection (f)'s definitions require that any front yard fence element above 18 inches be spaced no closer than 4 inches apart with members no wider than 4 inches, so solid privacy fencing is not permitted in the visible front-yard zone even with an approved permit, only the lower 18 inches may be opaque.
