Full Breakdown
Sec. " The rule bars all such work on Sundays entirely, since no Sunday window is listed. " That permit is not open-ended: Sec. 16-99(h) caps each renewal "for one or more periods, not exceeding one week each," so an emergency repair authorization has to be renewed weekly rather than issued once for an entire project. The hours sit inside the broader noise-control section, so the same enforcement machinery applies: the police department investigates complaints under Sec. 16-99(k) and must ask the apparent violator the reason before citing, and an "emergency situation" (restoring property after a calamity or protecting persons from imminent danger) is exempt from the section altogether under Sec. 16-99(c)(3).
Violations & Fines
A first violation of the construction-hours window draws a written warning under Sec. 16-99(l), with the officer logging the violator's name, address, and the incident details. A subsequent violation is a criminal fine of not less than $100 and not more than $300, with each day of continued out-of-hours work chargeable as it recurs; unpaid fines are recoverable by noncriminal disposition under M.G.L. c. 40, § 21D.
