Fence Installation · Union County, New Jersey
In New Jersey, there is no single statewide rule for a Fence Installation; whether you need a permit is decided locally in Union County.
Fences are governed mainly by local zoning, not a statewide building permit. Cities set height limits (commonly 3-4 ft in front yards and 6 ft in back and side yards), setbacks, and corner sight-line rules, and many require a zoning permit for any fence. Most jurisdictions exempt fences up to 7 ft from a building permit (IRC R105.2) and require one above that. Replacing a fence at the same height, material, and location usually needs no permit; a fence used as a pool barrier always does. Because New Jersey leaves this to local jurisdictions, the reliable answer comes from Union Building Inspector. Zoning setbacks apply either way.

Installing a new fence can improve privacy and property value. However, most counties require a permit if the fence exceeds 6 feet in height or is located in the front yard.
Given that Union County has a densely packed population of 579,290 residents, the local building department frequently experiences high application volumes. Expect processing times of 4 to 8 weeks for standard residential projects.
Because of severe winter weather in New Jersey, any exterior structures or footings must be set below the local frost line to prevent shifting, as mandated by the New Jersey Uniform Construction Code.
