Full Breakdown
Orange County amended Section 105.2 of the California Building Code so fences not over six feet high are exempt from a building permit in unincorporated areas. The exemption does not apply to walls and fences under six feet that a project approval, such as a subdivision or use permit condition, requires. Taller fences and walls fall under the general building-permit process administered by OC Public Works, separate from the Zoning Code's fence-height Site Development Permit or Use Permit required under Section 7-9-64 when height exceeds the district's setback limits.
Violations & Fines
Fences over six feet built without a permit are unpermitted construction; the Building Official can order a stop-work notice, require correction, or mandate a retroactive permit and inspection.
