Barbed wire, razor wire, and electrified fences are restricted in Duval residential zones under §656.407(g). Hurricane zones require fence materials and fastening capable of withstanding 140 mph wind loads per Florida Building Code.
Restricted materials in residential zones: barbed wire (only commercial/industrial or ag 5+ acres), razor wire (prohibited residential), electric fence (only agricultural use with posting). Prohibited throughout Duval: solid-panel fences exceeding height limits, fences using sharp projections above 6 ft that face sidewalks. Florida Building Code §1620 requires fences in coastal areas (east of US-1) to be engineered for 140-160 mph wind loads; typical residential wood fences comply if posts are set 24+ inches deep in concrete. Atlantic Beach and Jacksonville Beach (within Duval County) have additional sea-turtle-friendly material guidance along dune lines.
Prohibited material in residential: Notice of Violation, remove within 30 days. Hurricane-code violation on new construction: no final inspection until corrected.
