Noise Regulations in Maine
Overview
Maine does not have a statewide noise statute, though MRSA Title 17, Ch. 91 (§2701) covers civil nuisance in general. Municipalities set their own noise standards. Portland has the most detailed noise ordinance.
Residential Noise Limits
In Maine, the typical residential noise limit is 60 dB during the day and 50 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 Maine 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 Maine 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 Maine 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 Maine typically carry fines ranging from $100-$500. 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
Maine does not have a comprehensive statewide noise statute. Noise regulation is left to individual cities and counties, which means rules can vary significantly between neighboring jurisdictions. If you live in Maine, check your specific city or county code for the noise rules that apply to your location. The data below covers the major cities in Maine.

How to Handle Noise Issues in Maine

- Talk to your neighbor first: Many noise issues can be resolved with a polite conversation. Your neighbor may not realize they are causing a disturbance.
- File a complaint: Contact your local non-emergency police line or 311 service. Have your noise log available when you call.
