Monroe Township (Middlesex County), NJ Fence Regulations: Neighbor Fence Rules (2026)

Sections 108-8.2.B, C and E set the boundary rules for fences in the Township of Monroe. Subsection B requires every fence to be maintained in a safe, sound, up-right condition and to be erected with the framework or supporting structure facing the inside of the lot. Subsection C requires that, except for the corner lot exception in § 108-8.2.A(1), all fences be erected within six inches of the property lines, and that no fence encroach upon a public right-of-way. The six inch rule fixes where a boundary fence sits relative to the lot line, and the right-of-way bar keeps fences off the street side.

The corner lot exception moves the fence in the other direction. A six foot fence in the front yard of a residential corner lot must be set back a minimum of 10 feet from the street right-of-way in the R-5, R-7.5, R-10 and R-20 Zones, and 15 feet in the R-30, R-60 or R-3A Zones, with the Township Engineer certifying that it does not encroach upon the required site triangle.

Responsibility for condition is placed on the fence owner. Under subsection E, when the Zoning Officer determines on inspection that a fence or any portion of it is not being maintained in a safe, sound or upright condition, the Zoning Officer notifies the owner of the fence in writing, states briefly the reasons, and orders the fence or portion repaired or replaced within 30 days of the date of the written notice. The quoted sections speak of the owner of the fence and of the lot on which it is erected; they print no cost-sharing formula between adjoining owners.

A related neighbor protection sits in § 108-9.1.A(10): off-street parking areas for three or more vehicles and loading areas adjoining residential districts must be effectively screened by a fence or hedge on the side or sides that adjoin or face premises in a residential district.
