Ventura County, CA Fence Regulations: Material Restrictions (2026)

3, prohibits barbed wire, razor-edge wire, electric wire, or similar types of fencing in the county's urban residential zones and commercial zones, the zone classifications set out in Article 4. The word 'similar' matters: the ban is not limited to the named materials, so a fencing product that functions like barbed or electrified wire falls under the prohibition even if it is sold under another name. The rule also crosses zone lines in one direction. Industrial-zoned properties that abut, or sit across the street from, urban residential zoned properties may not use these materials if the fencing would be visible from the urban residential property or properties.

Visibility is the operative test on those industrial lots: an industrial yard whose fence line faces homes is restricted, while the ordinance's ban on these materials does not reach industrial fencing that cannot be seen from the neighboring residential property. This is a rule for the unincorporated county only. Oxnard, Thousand Oaks, Ventura, and the county's other incorporated cities each enforce their own fencing codes, so the first question for any property owner is whether the parcel sits inside city limits or in county territory.
