Corona, CA Fence Regulations: Material Restrictions (2026)

Corona Code of Ordinances § 17.70.060 restricts fence materials by zone and location, on top of the height rules in the same section. In any front yard setback, on a single-family or multiple-family lot, chain link fencing is flatly barred under subsection (F)(1)(e); the 60-inch front-yard fence allowance in that same subsection must instead be wrought iron, or decorative block up to 36 inches capped with wrought iron. Precision block left untreated with an exterior finish such as stucco is also prohibited in any front yard setback under subsection (F)(1)(g).

Commercial zones (the C-P, C-2 and C-3 districts, or any commercial district of a Specific Plan) are held to wrought iron or decorative block only; subsection (G) prohibits wood, precision block and chain link fencing outright anywhere in those zones. Industrial zones (M-1 through M-4, or an industrial Specific Plan district) require wrought iron or decorative block wherever the fence is visible from a public street, though the Director of Community Development can approve chain link or precision block out of public view; wood fencing is barred industry-wide under subsection (H).

Barbed and razor wire aren't banned outright citywide, but subsection (C) confines them to security fencing: commercial, industrial and agricultural zones may add up to two feet of security fencing above the standard height allowance, and that add-on can be barbed or razor wire, or a wrought-iron extension. Multi-family zones get their own security option, an all-wrought-iron perimeter fence raised to eight feet, but barbed or razor wire isn't part of that multi-family allowance.
