Monroe Township (Middlesex County), NJ Outdoor Lighting: Dark Sky Rules (2026)

Monroe Township's lighting limit is a performance standard in Chapter 108, Land Development, § 108-5.21(D)(12), titled Lighting and illumination. It applies to artificial lighting or illumination provided on any property or by any use. Three rules follow. Illumination from artificial lighting cannot exceed 0.5 footcandle beyond any property line. Spotlights or other lighting that provides a concentrated beam must be directed so the beam does not extend beyond any property line. Spotlights used to illuminate signs or building faces cannot emit beams that extend beyond the vertical plane of the sign or building face, and cannot be located so the light reflects upon any adjoining property, public street or vehicular circulation area.

The glare standard in § 108-5.21(D)(11) works alongside it: no direct or sky-reflected glare exceeding 1-1/2 foot-candles measured at the boundaries of the lot where the source is located, and no illumination above 0.1 footcandle in residential districts from an operation producing intense glare. The glare limit does not apply to lights used solely to illuminate entrances, exits or driveways leading to a parking lot.

Other sections add design rules. Under § 108-12.13, parking areas for five or more motor vehicles must be lit to a minimum of 1/2 horizontal footcandle average at the surface, with the minimum at any location at 75% of the average, and freestanding poles cannot exceed the height of the adjacent buildings served or a maximum of 20 feet. Major pedestrian walkways used by the public after sunset outside street rights-of-way need a 1/2 horizontal footcandle average. Swimming pool lights must be shielded so no direct beam shines on an adjoining property (§ 108-12.31(B)), illuminated signs must be properly shielded to prevent glare on traffic (§ 108-10.1(E)(2)), and in the N-C Neighborhood Commercial District section (§ 108-6.17) freestanding fixtures for a planned retail village center are capped at 14 feet with the source recessed and shielded within the fixture.

Under § 108-5.21(A), the applicant must supply evidence satisfactory to the municipal agency that the use conforms fully to the performance standards, and the agency can require certification of tests by government agencies or recognized laboratories at the applicant's cost.
