Full Breakdown
Section 90403.05 of Imperial County's land use code sets out when a fence needs a construction permit. Ordinary fences, wood, chain link, wrought iron and similar materials, need a permit once they exceed eighty-four inches in height in any zone. Masonry fences over four feet also require a permit, plus an engineer- or architect-designed plan under the 2019 California Building Code as adopted by the county. Retaining walls over four feet, or any height if they hold back a surcharge or Class I, II or IIIA liquids, need a permit too. Fences under six feet made of wood, stucco, wrought iron or chain link are exempt under Section 90403.01.
Violations & Fines
Building a fence taller than 84 inches, or a masonry or retaining wall over 4 feet, without first pulling a permit violates Imperial County Code § 90403.05 and can trigger a stop-work order.
