Riverside, CA Fence Regulations: Material Restrictions (2026)

Section 19.550.020 of Riverside's Zoning Code states plainly that 'fences or walls containing razor wire (visible to a public right-of-way, alley or parking lot), or barbed wire shall be prohibited.' That leaves no residential exception, a homeowner cannot top a fence with barbed or razor wire anywhere in the city, and even non-residential barbed or razor wire must stay out of view from streets, alleys, and parking lots to avoid the ban. For property owners who want a stronger security barrier, the code offers a narrow substitute: §19.550.025 permits 'monitored electrified security fence systems,' but with heavy conditions.

The energizer must run off a commercial storage battery not exceeding 12 volts DC, charged primarily by a solar panel (§19.550.025(B)); the electrified wire must sit four to eight inches behind a minimum five-foot non-electrified perimeter fence (§19.550.025(C)); the system can't exceed ten feet in height (§19.550.025(D)); and it must carry 'Warning-Electric Fence' signs at intervals of no more than 30 linear feet (§19.550.025(F)). Location is tightly limited, §19.550.025(G)(1) bans these systems outright in all residential, mixed-use, and public facilities zoning districts, restricts them to industrial zones and specific commercial uses listed in Table 19.150.020.B, and §19.550.025(G)(5) bars installation on any property adjacent to a park.

Every monitored electrified system also needs an alarm user's permit under Chapter 5.58, and any system abutting a residential property or within 300 feet of a park, childcare facility, recreation center, community center, or school needs a building permit and a minor conditional use permit under §19.550.025(H).
