Piscataway, NJ Fence Regulations: Fence Permit Requirements (2026)

Piscataway Township's Building Subcode fee schedule at § 14-1.3.a.1 lists "Fence - over 6 feet high or pool enclosure" as a construction-permit line item, billed at $27 per $1,000 of construction cost with a $75 minimum fee, payable to the Construction Official's office in the Building Division of the Department of Community Development before the permit issues. Fences at or under that six-foot threshold are governed instead by the zoning height and placement standards at § 21-619, last amended by Ordinance No. 2025-26 and Ordinance No.

2026-01. In a residential zone, a front-yard fence cannot exceed 4 feet in height and cannot be more than 50% solid where it would restrict visibility, though a corner-lot fence along the street frontage used as a side yard may extend into the front yard setback for half the required setback distance. In a commercial or industrial district, a fence or wall cannot exceed 6 feet, except that one set behind the front yard setback line may reach 8 feet, and no corner-lot fence is permitted unless it conforms to § 21-606.

Barbed wire and metal spikes atop any fence are prohibited outright, and every fence must be installed with its finished side facing outward, away from the enclosed area. Because the fee schedule and the zoning chapter both key off the same six-foot line, a property owner planning anything taller than a standard residential fence in Piscataway should expect both a Construction Code permit fee and a zoning check before the fence goes in.
