2 rules for unincorporated Hampshire County, Massachusetts.
Verified from official government sources
Massachusetts has no statewide dark-sky lighting law for private property, and Hampshire County cannot make one. Any shielded-lighting or dark-sky requirement comes from a city or town zoning bylaw or site-plan condition, which vary widely across Northampton, Amherst, and Easthampton.
No Massachusetts statute limits light spilling onto a neighbor's property, and Hampshire County cannot regulate it. Remedies come from a city or town lighting or nuisance bylaw and from a common-law private-nuisance claim, not county code enforcement.
