Gardena, CA Fence Regulations: Material Restrictions (2026)

Gardena Municipal Code § 18.42.070(D) states flatly that no electrically charged fence or barbed wire or razor-ribbon type fencing shall be permitted in any zone in the city, except as provided in subsection E. That exception, § 18.42.070(E)(2), is narrow and commercial-only: for commercial and industrial uses, three strands of barbed wire may be placed atop a fence at least six feet high that is not visible from a street or highway, and razor-ribbon wire may be placed atop a fence at least eight feet high, but only with an approved conditional use permit under Chapter 18.46 and only if it is not visible from a street or highway.

No such exception exists for residential properties; a homeowner cannot add barbed wire or an electric fence to a residential lot under any circumstance. Beyond the outright prohibitions, § 18.42.070(A)(2) also limits what materials a residential front-yard fence may use at all: wood, wrought iron, tubular steel, stone, brick, stucco, or decorative block such as slump stone or split-faced block, with wrought iron or tubular steel sections required to be interspersed with stone, brick, stucco, or decorative block at least every eight feet. Nonresidential fences carry a parallel materials list under § 18.42.070(A)(3)(a): wrought iron, tubular steel, stone, brick, stucco, or decorative block.

Section 18.42.070(E)(1) preserves any fence, hedge, or wall required by federal or state law regardless of these material rules. Community Development reviews fence permits for material compliance before issuance, and enforcement against unlawful electric or barbed-wire fencing runs through the city's general code-enforcement and penalty provisions in GMC Chapter 1.04.
