Union City, NJ Outdoor Lighting: Dark Sky Rules (2026)

Outdoor lighting regulation in Hudson County reflects pragmatic urban concerns rather than dark-sky astronomy goals. The entire county sits within the New York metropolitan light dome with Class 8-9 Bortle sky conditions — starlight is effectively unobservable. Hudson municipalities therefore focus light regulation on (1) preventing light trespass onto neighboring residential properties, (2) avoiding glare onto streets and pedestrian areas, and (3) energy efficiency. Jersey City Zoning requires full-cutoff (fully shielded) fixtures for new commercial and multi-family development, with maximum footcandle levels at property lines typically 0.5 fc. Hoboken Zoning §196 imposes similar shielding requirements with heightened standards in historic districts where fixture aesthetics must match contributing architectural periods. Parking lot lighting pole heights typically capped at 20-30 feet. LED color temperature guidance favors 3000K or below (warmer) to reduce blue light spillover — though not strictly enforced. Street lighting across Hudson County is transitioning to LED through PSE&G and Jersey City Lighting programs. Rooftop and terrace lighting on new Jersey City towers must be designed to minimize sky glow and avoid aviation hazard — FAA coordination required above certain heights. Decorative holiday lighting is generally exempt within reasonable seasonal limits.
