Chester County does not regulate light spilling onto a neighbor's property. Light-trespass limits are set in municipal lighting ordinances, where many Chester County townships cap illumination at property lines using shielded, full-cutoff fixtures.
Light trespass — unwanted light crossing onto adjacent property — is addressed through municipal outdoor-lighting ordinances adopted under the PA Municipalities Planning Code (53 P.S. §10101 et seq.), not by the county. Chester County townships that have adopted Pennsylvania Outdoor Lighting Council model provisions typically limit vertical illuminance at the property line (often measured about 5 feet above grade) and require full-cutoff, shielded fixtures aimed downward. If a neighbor's floodlight shines into your home, the remedy is your municipality's zoning or code enforcement office; the county has no authority over private residential lighting.
Where a municipal ordinance sets a light-trespass limit, exceeding it is a code violation; the township can order re-aiming or shielding of fixtures and impose fines for non-compliance.
