Light trespass across property lines in Allegheny County handled through municipal lighting ordinances and common-law nuisance. Pittsburgh limits spillover to 0.5 footcandles at residential property lines.
Pittsburgh Zoning §915.03.E caps light trespass at 0.5 footcandles measured at residential property lines and 1.0 footcandle at commercial boundaries. Violations typically arise from parking lot lighting, sports field lighting, and billboards adjacent to homes. Enforcement requires a certified meter reading by Pittsburgh BBI or independent lighting consultant. PA common-law nuisance applies where lighting substantially interferes with use and enjoyment of property under Restatement (Second) of Torts §822. Mt Lebanon, Fox Chapel, and Edgeworth have similar footcandle limits.
Pittsburgh lighting violations: 250 dollars per occurrence plus required remediation. Civil nuisance suits can seek injunctive relief and damages.
