Dark Sky Outdoor Lighting Bylaw
Potential new regulations on outdoor lighting to reduce light pollution may apply to commercial, industrial, multi-family, or residential properties.
The Planning Board is exploring a Dark Sky outdoor lighting bylaw to curb light pollution. Two meetings have framed the central question of whether rules should apply to residential properties or be limited to commercial and municipal sites. No draft has yet been prepared for Town Meeting.
The Dark Sky Outdoor Lighting Bylaw first surfaced as a formal agenda item during the Planning Board's May 26, 2026 meeting when staff presented examples of lighting regulations from Maynard and Chelmsford. Board members examined how such bylaws address glare, color temperature, and light trespass, while debating the appropriate reach of any new rules.
Discussion centered on whether enforcement should target only commercial, industrial, and multi-family properties or extend to single-family homes. Several residents voiced support for beginning with municipal and commercial sites to build acceptance before considering broader application.
At the June 9, 2026 meeting the board revisited the topic after receiving an email summary from the Chelmsford Planning Board Chair describing that town's experience. The Chair expressed a preference for a bylaw covering both residential and commercial properties yet emphasized the need for continued public input.
No formal vote or draft language has been introduced. The board has instead treated the matter as an ongoing placeholder, with one member designated to lead research and outreach aimed at a possible Town Meeting proposal in fall 2026 or spring 2027.
Speaker R will follow up with the Chelmsford Board Chair; Speaker P will continue research and public engagement toward a possible proposal in Fall 2026 or Spring 2027.
