New light trespass bylaw sets 10 lux limit to prevent neighbor-to-neighbor glare
Key Points
- New bylaw regulates light "spilling" onto neighboring properties
- Sets a 10 lux limit; property owners have 30 days to remediate violations
- Exempts holiday lights and motion sensors on timers
Article 8, a new "light trespass" bylaw, was adopted to regulate excessive light shining from one property onto another. The bylaw establishes a threshold of 10 lux, a limit that Warrant Committee Chair Jay Funling described as more generous than other towns
but necessary to address nuisance lighting in residential areas.
Under the new rules, if a resident reports a light nuisance, inspectional services will investigate. If a violation is found, the owner has 30 days to fix the issue by redirecting the light, using a dimmer, or turning it off. Funling emphasized that this is not a broad "dark skies" law meant to curb general light pollution, but a neighbor-to-neighbor protection. This is to prevent excessive light shining from one person's property into another's,
he said.
The bylaw includes several exceptions, including holiday lighting, athletic fields, emergency lighting, and motion-sensing lights that are on a timer. Despite some skepticism from Board of Health Chair Roxanne Musto, who questioned the "arbitrary" nature of visual discomfort, Town Meeting voted to include town-owned property under the regulation, ensuring that residents are protected from bright municipal lights as well as those of their neighbors.
Motion: B. Zul moved that the Town adopt the Light Trespass Bylaw as recommended by the Warrant Committee, with a 10 lux threshold and inclusion of town-owned property.
Vote: Passed 136-30
