Noise from Specific Sources in Brockton, MA: What Residents Actually Need to Know

Brockton maintains 106 local ordinances across all categories, and 2 of those deal specifically with noise from specific sources. Here is a breakdown of what the city actually requires, what is prohibited, and where Brockton falls on the strict-to-permissive spectrum compared to other cities.

Car Alarm Limits

Brockton exempts car alarms and other warning devices from its noise ordinance as long as they do not sound continuously for more than 30 minutes. Past that window, the alarm becomes an enforceable nuisance under Sec. 14-50.

Key details: Governing section: Brockton City Code § 14-50(g)(1)f. Exempt duration: Up to 30 continuous minutes per incident. Nighttime decibel cap (if not exempt): 50 dBA, 10 p.m.-7 a.m. weeknights. First violation: Written warning only. Repeat violation fine: $300 per offense.

A first violation in any 12-month period draws a written police warning only. Any subsequent violation within that same 12-month period carries a $300 civil fine, and repeat cases can also be enforced under M.G.L. c. 40, § 21D as a noncriminal civil infraction.

Brockton is more permissive than most cities when it comes to car alarm limits. That said, there are still limits.

Generator Noise

Emergency standby and backup generator noise is exempt from Brockton's noise ordinance at all times under Sec. 14-50(g)(1)c. Non-emergency generator use still falls under the citywide 50-decibel nighttime cap.

Key details: Governing section: Brockton City Code § 14-50(g)(1)c. Emergency backup generators: Exempt from noise code at all times. Non-emergency generator noise: Subject to 50 dBA nighttime cap. First violation: Written warning only. Repeat violation fine: $300 per offense.

A first substantiated complaint in a 12-month period results only in a written police warning. Each subsequent violation within that same 12 months carries a $300 civil penalty, enforceable as a noncriminal civil infraction under M.G.L. c. 40, § 21D.

If you are coming from a city with tighter rules, you will find Brockton gives residents more flexibility on generator noise.
