Pomona, CA Fence Regulations: Material Restrictions (2026)

The Code's Design and Installation standard, Sec. c, splits fencing material into a permitted list and a prohibited list, and every new wall, fence or gate must be built from the permitted side. Allowed materials are masonry (brick, stone or concrete, each requiring an architectural cap), sealed wood, wrought iron, vinyl, or another material the Development Services Director determines is customarily used for wall and fence construction. The prohibited list, Sec. ii, is broader and covers four categories. First, scrap or recycled material: tires, garage doors, sheet metal, plywood, windows, corrugated metal, inoperable vehicles and parts, construction debris, household waste and yard debris.

Second, chain link is banned outright for permanent fencing, though Sec. 4 allows temporary chain-link fencing around an active construction site if the Development Services Director permits it. Third, security fencing material is prohibited, specifically barbed wire, concertina wire, razor wire and electric fencing. Fourth, sharp material is banned from the top of any fence or wall, including glass shards, spikes and nails, though decorative spikes that are part of an ornamental metal fence are exempted. Every fence and wall, permitted materials included, must also be kept vertical, structurally sound and protected from deterioration under the Code's maintenance standard.
