Full Breakdown
Bostonia follows San Diego County's Building Division rules. A building permit is required for any fence except fences and freestanding masonry walls not exceeding 6 feet in height that comply with the County Zoning Ordinance, and open fences up to 8 feet where the top two feet are barbed or razor wire for security. Even when no building permit is needed, the fence must still meet the Zoning Ordinance height limits (42 inches front, 72 inches rear/side). Retaining walls over 3 feet always require a building permit. Apply through County Planning & Development Services.
