Residential Noise Limits
In Massachusetts, the typical residential noise limit is 55 dB during the day and 45 dB at night. These limits are measured at the property line of the receiving property using the A-weighted decibel scale (dBA). Some jurisdictions within Massachusetts use a "plainly audible" standard instead of or in addition to specific decibel measurements.
Quiet hours — the period when stricter nighttime limits apply — run from 10:00 PM to 7:00 AM in most Massachusetts jurisdictions. During these hours, activities that generate noise above the nighttime limit may result in a citation. Exemptions typically apply to emergency services, emergency repairs, and certain agricultural operations.
Construction Noise
Construction in Massachusetts is generally permitted from 7:00 AM to 6:00 PM on weekdays. Some cities allow Saturday construction with shorter hours (often 8:00 AM to 5:00 PM), while Sunday and holiday construction is typically prohibited in residential areas. Emergency construction and utility repairs are usually exempt from time restrictions.
Fines and Penalties
Noise ordinance violations in Massachusetts typically carry fines ranging from $200-$1,000. First-time offenders usually receive a warning or the minimum fine. Repeat offenders face escalating penalties. In some jurisdictions, chronic noise violations can be classified as misdemeanors, and equipment generating the noise may be subject to seizure. Commercial establishments that repeatedly violate noise codes may face license suspension or revocation.
State Law
Massachusetts has a statewide noise statute that establishes baseline noise standards. This law sets maximum permissible noise levels by zone classification and time of day. Cities and counties within Massachusetts may adopt stricter standards than the state baseline, but they cannot be more lenient. The state environmental or health department typically enforces industrial and commercial noise standards, while local law enforcement handles residential noise complaints.
