Full Breakdown
Orange County Codified Ordinances § 7-9-64 sets a tiered height scheme in the unincorporated area: solid fencing tops out at 3.5 feet in the front setback (up to 20 feet deep), open fencing or pilasters can reach 5 feet there, and rear or side setbacks not fronting a street allow 6 feet (8 feet if measured from a higher adjoining lot). Near street corners and driveway/alley intersections, fences and hedges drop to 3.5 feet inside the sight-triangle areas defined in subsections (d) and (e) so drivers can see cross traffic. Taller fences need a Site Development Permit (up to 8 feet) or a Use Permit (over 8 feet) from the Zoning Administrator.
Violations & Fines
Fences over these limits without an approved Site Development Permit or Use Permit are a zoning violation subject to code enforcement correction or removal by OC Public Works/OC Community Resources.
