2 rules for unincorporated Morris County, New Jersey.
Verified from official government sources
New Jersey has no statewide dark-sky or outdoor-lighting law, and Morris County does not regulate residential lighting. Any full-cutoff fixture, shielding, or brightness requirement comes from your municipality's zoning ordinance. Many NJ towns adopt model dark-sky ordinances, but adoption is optional and varies town to town.
Neither Morris County nor New Jersey has a statewide light-trespass law. Whether spillover light onto a neighbor's property is prohibited depends on your municipality's lighting or nuisance ordinance. Many NJ towns' model lighting ordinances limit illumination crossing property lines; some address excessive holiday displays.
