Full Breakdown

No Plymouth County construction-hour rule exists, because Massachusetts counties cannot legislate. Each town sets permitted work times in its noise or general bylaw, authorized by MGL c.40 §21(22). Plymouth, Marshfield, and Scituate limit powered construction to roughly 7 a.m. through evening on weekdays, with shorter Saturday windows and no Sunday work. Brockton's ordinance runs similar hours. Emergency utility repairs are exempt. The town building commissioner and police enforce the schedule; Plymouth County plays no role.

Violations & Fines

Working outside permitted hours draws a bylaw fine up to $300 per offense under MGL c.40 §21, plus a possible stop-work order from the town building department.
