1 county-level rule, plus city-specific rules for 3 cities in Middlesex County, New Jersey.
Verified from official government sources
Middlesex County does not regulate residential fence heights. Under the New Jersey Municipal Land Use Law (N.J.S.A. 40:55D-1 et seq.) and N.J.S.A. 40:48-1, each of the county's 25 municipalities sets its own fence rules through its zoning ordinance. Edison Township (Chapter 37, Zoning) caps residential fences at 6 feet and front-yard fences at 4 feet, with sight-triangle limits of 3 feet on corner lots. New Brunswick's Land Development Ordinance imposes similar 4-foot front / 6-foot rear standards. Most Middlesex towns (Perth Amboy, Woodbridge, East Brunswick, Piscataway, Old Bridge) follow the same 4 ft / 6 ft template. Fence permits are issued by each town's zoning office, not the county.
