Boston addresses light trespass through its zoning code and general nuisance provisions. Commercial and industrial lighting must not cause glare or direct illumination on adjacent residential properties. Complaints about intrusive lighting are handled through 311 and may result in ISD enforcement for commercial sources.
Light trespass in Boston — where outdoor lighting from one property spills onto adjacent properties — is regulated through the zoning code for commercial properties and through general nuisance law for residential areas. The Boston Zoning Code requires that commercial, industrial, and institutional lighting be designed and installed to direct light onto the intended area without causing glare on adjacent properties or roadways. BPDA site plan reviews for large developments typically include photometric plans demonstrating compliance. For residential disputes, light trespass is addressed as a nuisance under common law and city ordinances. Neighbors can file complaints through 311, and ISD may investigate commercial or institutional light trespass. Massachusetts common law provides that unreasonable light intrusion that substantially interferes with the use and enjoyment of property may constitute a private nuisance actionable in civil court. Security lighting and motion-activated lights are generally permitted but should be aimed to minimize off-property illumination.
Commercial light trespass violations may result in zoning enforcement by ISD with required corrective action. Persistent residential light trespass may be addressed through civil nuisance claims in court. No specific municipal fine for residential light trespass, but commercial violations carry standard zoning enforcement penalties.
