Union County, NJ Fence Regulations: Material Restrictions (2026)

Fence material regulation in Union County reflects the county's urban-suburban mix. Elizabeth Land Development Code Chapter 20.84 permits standard residential materials (wood, vinyl, composite, wrought iron, aluminum, chain-link) in residential zones but restricts chain-link to side and rear yards in R-1 through R-3 districts. Barbed wire and razor wire are prohibited in all residential zones but permitted on industrial M-1 and M-2 parcels along the NJ Turnpike, Routes 1-9, and the Bayway Refinery corridor subject to Fire Department (Chapter 15.28) review for emergency access. Westfield Land Use Ordinance §13.03D prohibits chain-link in required front yards across all residential districts and requires wrought-iron or wood for corner lot side yards adjacent to streets. Summit Zoning §3.4-10 similarly restricts chain-link. Cranford's North Avenue and Downtown Historic Districts require Historic Preservation Commission review for any visible fence, typically mandating wood picket, wrought iron, or approved period-appropriate materials. Plainfield's Van Wyck Brooks Historic District enforces similar review. The NJ 'good-side-out' rule (finished side facing neighbor) is codified in most Union County municipal codes. HOAs in Clark, New Providence, and planned communities impose additional material restrictions.
