Montgomery County has no light-trespass rule. Whether stray light spilling onto a neighbor's property is limited depends on your borough or township lighting ordinance. Persistent glare may also be a private nuisance under PA common law.
Light trespass — light from one property shining onto another — is not regulated by the county. Where a Montgomery County municipality addresses it, the rule sits in the zoning or land-development ordinance adopted under MPC Section 603(b) and typically caps the illumination (in foot-candles) measured at the property line and requires shielded, downward-directed fixtures. Not every municipality has such a standard, especially for existing single-family homes. Where no ordinance applies, an affected neighbor's remedy is a private-nuisance claim under Pennsylvania common law, which requires showing the light causes a substantial and unreasonable interference with the use of their property. Start by checking your municipality's outdoor-lighting standards.
Where a lighting ordinance exists, exceeding property-line light limits is a municipal violation subject to correction orders and fines. Absent an ordinance, disputes are resolved privately as a nuisance claim, not by the county.
