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