Noise Ordinances in Nashua, NH: What Residents Actually Need to Know

If you live in Nashua or are thinking about moving there, noise ordinances are one of those things you probably won't think about until they affect you directly. Nashua has 9 specific rules on the books covering different aspects of noise ordinances, and some of them might surprise you.

Construction Hours

Nashua codifies a strict construction quiet window in Chapter 128 (Construction and Demolition Work) of Part II. There shall be no construction or demolition in any residential zone (as defined in Chapter 190, Land Use) or within 600 feet of any dwelling unit between 8:00 p.m. and 7:00 a.m. Sunday through Friday, and between 7:00 p.m. Saturday and 8:00 a.m. Sunday and holidays. Emergency work directed by the Director of Code Enforcement and work authorized by the Director of Public Works are exempt. Primary enforcement is by Nashua Police; Code Enforcement and the Zoning Administrator also have authority.

Key details: Code Authority: Nashua Chapter 128 (Construction and Demolition Work). Restriction: No construction/demolition in residential zones or within 600 feet of any dwelling unit. Quiet Window Sun-Fri: 8:00 p.m. - 7:00 a.m.. Quiet Window Saturday Night - Sunday Morning: 7:00 p.m. Sat - 8:00 a.m. Sun. Sundays and Holidays: No construction/demolition at all (full quiet day).

Construction or demolition in a residential zone or within 600 feet of any dwelling unit outside the permitted hours (8 p.m. - 7 a.m. Sun-Fri; 7 p.m. Sat - 8 a.m. Sun; all day Sundays / holidays) is a Chapter 128 violation, fine not less than $100, each day a separate offense. The Nashua Police Department has primary enforcement; Code Enforcement Director and Zoning Administrator also have authority. Noise that becomes 'unreasonable or excessive' even within permitted hours is citable under Chapter 201 (Noise) and NH RSA 644:2 disorderly conduct (violation up to $1,000; Class B misdemeanor if continued after desist order). Report after-hours construction to Nashua Police non-emergency 603-594-3500 or Code Enforcement at 603-589-3330.

Aircraft Noise

Aircraft-in-flight noise is preempted by the Federal Aviation Administration under the Airport Noise and Capacity Act of 1990 (49 U.S.C. 47521 et seq.). Boire Field / Nashua Municipal Airport (FAA identifier ASH / ICAO KASH), at 93 Perimeter Road in northwest Nashua, is operated by the Nashua Airport Authority. The FAA determined that the airport's FAR Part 150 Noise Exposure Maps are in compliance with applicable requirements effective April 29, 2009. Nashua Chapter 201 contains no aircraft-noise provisions. The airport publishes voluntary noise-abatement procedures favoring Runway 32 as the preferential runway, with Runway 14 departures climbing on runway heading to 1,000 feet MSL before turning over the F.E. Everett Turnpike.

Key details: Local Aircraft Noise Rule: None - federally preempted (FAA / ANCA 1990). Airport: Boire Field / Nashua Municipal Airport (ASH / KASH), 93 Perimeter Road. Operator: Nashua Airport Authority. FAA Part 150 NEM Status: Compliant effective April 29, 2009. Preferential Runway: Runway 32.

No city-issued noise citation is possible for aircraft in flight (federally preempted under 49 U.S.C. 47521 et seq. and 49 U.S.C. 40103). Submit aircraft noise complaints directly to the Nashua Airport Authority at Boire Field (KASH), 93 Perimeter Road, Nashua, NH 03063. The federal mechanism for community-wide aircraft-noise mitigation is the FAA Part 150 Noise Compatibility Program process - the Nashua Airport Authority's Part 150 Noise Exposure Maps were FAA-approved effective April 29, 2009. Voluntary noise-abatement procedures (Runway 32 preferred; Runway 14 departures climb to 1,000 MSL before turning over the F.E. Everett Turnpike) are not enforced by the city.

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

Quiet Hours

Nashua codifies noise in Chapter 201 (Noise) of Part II of the Revised Ordinances, adopted by the Board of Aldermen on August 9, 2005 by Ordinance O-05-96. Chapter 201 does not publish a single citywide clock-time 'quiet hours' window for all noise. It establishes specific time-based prohibitions: yelling, shouting, hooting, whistling or singing on public streets is unlawful between 11:00 p.m. and 7:00 a.m. (or at any time so as to annoy or disturb neighboring premises). Operating an electronic sound-reproduction device so as to disturb peace, quiet and comfort of neighboring inhabitants is unlawful at all hours - operation clearly audible at 50 feet is prima facie evidence. New Hampshire RSA 644:2 (disorderly conduct) is the statewide backstop for loud or unreasonable noise.

Key details: Code Authority: Nashua Revised Ordinances Chapter 201 (Noise), Part II - adopted 8-9-2005 by O-05-96. Public Street Quiet Window: 11:00 p.m. - 7:00 a.m. (yelling, shouting, hooting, whistling, singing). Audible Distance Trigger: Sound-reproduction device audible at 50 feet = prima facie violation. School / Hospital / Court / Church Rule: No unreasonable or excessive noise on adjacent streets when in use (where signs posted). State Backstop: RSA 644:2 disorderly conduct - violation up to $1,000; Class B misdemeanor if continued after desist order.

Chapter 201 violations are punished under § 201-7 / general penalties of Part II: any person who violates any portion of the chapter is, upon conviction, guilty of a violation and fined not less than $100, and shall receive a written order to cease or abate the noise immediately or within such reasonable time period as the enforcing official shall order. Each day of continued violation is a separate offense. RSA 644:2 (disorderly conduct) is the statewide backstop - a violation (up to $1,000 fine) for loud or unreasonable noise that disturbs a person of average sensibilities; it escalates to a Class B misdemeanor (up to 1 year incarceration) if the conduct continues after a desist order. Report active disturbances to Nashua Police non-emergency at 603-594-3500.

Barking Dogs

Nashua codifies animal-noise enforcement in Chapter 93 (Animals). Noise from an animal that is sustained for periods of more than 30 minutes, or that occurs between 10:00 p.m. and 6:00 a.m., which would annoy or disturb a person of normal sensibilities, is declared a nuisance. The owner who fails to abate the nuisance after being requested to do so is guilty of a violation. The Nashua Police Department enforces, with penalties under § 93-14. Animal noise also remains citable under Chapter 201 and NH RSA 644:2 disorderly conduct.

Key details: Code Authority: Nashua Chapter 93 (Animals) - nuisance definition + § 93-14 penalty. Duration Trigger: More than 30 minutes (any time of day). Nighttime Trigger: Any animal noise between 10:00 p.m. and 6:00 a.m.. Standard: Would annoy or disturb a person of normal sensibilities. Owner Duty: Effectively abate after request by any person; failure is a violation.

Failure to abate animal-noise nuisance after a request is a Chapter 93 violation under § 93-14 - fine not less than $100 per occurrence (consistent with Part II general penalty), each occurrence a separate offense. Animal noise is alternatively citable under Chapter 201 (Noise) as disturbing peace, quiet and comfort - violation, fine not less than $100, plus a written cease/abate order. NH RSA 644:2 (disorderly conduct) is a state-law backstop - violation up to $1,000; Class B misdemeanor (up to 1 year jail) if continued after desist order. Enforcement is by the Nashua Police Department. Report barking complaints to Nashua Police non-emergency at 603-594-3500.

Industrial Noise

Industrial noise in Nashua is regulated through Chapter 201 (Noise) - the disturbance / 50-foot audibility standard - layered with Chapter 190 (Land Use Code) industrial-performance standards and the Chapter 128 residential-zone construction-equipment quiet window (8 p.m. - 7 a.m. weekdays; no Sunday/holiday). NH RSA 644:2 disorderly conduct is the statewide backstop. New Hampshire has no statewide environmental noise dB code (unlike WAC 173-60). Active industrial concentrations include the Sundial Avenue and Crown Street industrial parks, the Daniel Webster Highway south light-industrial corridor, the Amherst Street rail-served sites, and the former mill complexes along the Nashua River (many now in adaptive-reuse mixed-use redevelopment).

Key details: Code Authority: Nashua Chapter 201 (Noise) + Chapter 190 (Land Use Code) industrial performance standards + Chapter 128. Numeric dBA Matrix: None codified (NH has no statewide environmental noise dB framework). Performance Standard: Chapter 190 - noise/vibration/emissions controlled so as not to be detrimental or cause a nuisance to nearby areas. Residential-Zone Construction-Equipment Window: 8 p.m. - 7 a.m. Sun-Fri; 7 p.m. Sat - 8 a.m. Sun; no Sun/holiday (Ch. 128, within 600 ft of dwelling). State Backstop: NH RSA 644:2 disorderly conduct.

Industrial noise that disturbs neighbors' peace, quiet and comfort is a Chapter 201 (Noise) violation - fine not less than $100, written cease/abate order, each day a separate offense. Violations of Chapter 190 industrial-performance standards (or site-plan noise conditions) are zoning violations enforceable by the Code Enforcement Department and Zoning Administrator. Construction-equipment operation in residential zones or within 600 feet of any dwelling outside permitted Chapter 128 hours is a Chapter 128 violation (same $100 minimum penalty). NH RSA 644:2 (disorderly conduct, statewide) is a violation up to $1,000; Class B misdemeanor up to 1 year if continued after desist order. Rail operations are federally preempted (49 U.S.C. 10501(b)). Federal highway noise is administered under 23 CFR 772.

Leaf Blower Rules

Nashua does not publish a leaf-blower-specific ordinance and has not banned gas-powered blowers. Leaf-blower use is governed by Chapter 201 (Noise) - the disturbance / 50-foot audibility standard for electronic sound-reproduction devices does not directly cover internal-combustion equipment, so enforcement against leaf-blower noise relies on the Chapter 201 reasonableness standard plus, where applicable, Chapter 128 construction-equipment-noise restrictions or NH RSA 644:2 disorderly conduct. New Hampshire has not enacted statewide leaf-blower preemption, but no Nashua-specific bans, hour restrictions, or registration program exist.

Key details: Leaf Blower-Specific Code: None. Gas Blower Ban: None. Battery-Electric Requirement: None. Time-of-Day Restriction (Chapter 201 backstop): None blower-specific; general reasonableness standard applies. Construction-Equipment Quiet Window (if Ch. 128 applies): 7 a.m. - 8 p.m. Sun-Fri; 7 p.m. Sat - 8 a.m. Sun; no Sunday/holiday.

No leaf-blower-specific Nashua penalty exists. Excessive use is enforceable as a Chapter 201 (Noise) violation (fine not less than $100; written cease/abate order; each day a separate offense) where it disturbs neighbors' peace, quiet and comfort. Pre-7 a.m. weekday or Sunday/holiday commercial landscape work that fits Chapter 128 (Construction and Demolition Work) inside a residential zone or within 600 feet of any dwelling is a Chapter 128 violation. NH RSA 644:2 (disorderly conduct, statewide) is a violation up to $1,000; Class B misdemeanor up to 1 year if continued after desist order. HOA covenant violations are civil and enforced by the association. Report to Nashua Police non-emergency at 603-594-3500.

If you are coming from a city with tighter rules, you will find Nashua gives residents more flexibility on leaf blower rules.

Amplified Music & Events

Chapter 201 (Noise) makes it unlawful to operate any radio, receiving set, television, phonograph, stereo, record player, tape player, cassette player, compact disc player, loudspeaker, sound amplifier, or other electronic device for producing, reproducing or amplifying sound in such a manner as to disturb the peace, quiet and comfort of inhabitants of neighboring premises. Operation clearly audible at 50 feet from the source is prima facie evidence of violation. The chapter separately bars amplified sound cast upon the public streets for commercial advertising or to attract attention to a building. Motor-vehicle amplification > 50 feet is also barred at § 201-1.

Key details: Code Authority: Nashua Chapter 201 (Noise) - reasonableness + 50-foot prima facie rule. Prima Facie Audibility Trigger: Clearly audible at 50 feet from the source. Motor-Vehicle Amplification (NCO 201-1): Audible more than 50 feet from vehicle prohibited. Commercial Advertising Sound: Prohibited (sound cast on public streets for advertising / attracting attention). Entertainment District Overlay: None - citywide reasonableness standard.

Operation of any electronic sound-reproduction device in a manner that disturbs neighbors - or audible at 50 feet (prima facie) - is a Chapter 201 violation, fine not less than $100, plus a written cease/abate order; each day a separate offense. Motor-vehicle audio audible > 50 feet is a Chapter 201 / NCO 201-1 violation enforced by Nashua Police, often in conjunction with NH RSA 266:59 motor-vehicle equipment law. NH RSA 644:2 (disorderly conduct, statewide) is a violation up to $1,000; Class B misdemeanor (up to 1 year jail) if continued after a desist order. Event-permit holders violating permit conditions face permit revocation and denial of future permits. Report to Nashua Police non-emergency 603-594-3500.

Decibel Limits

Nashua Chapter 201 (Noise) does not codify a general numeric dBA cap. The city's principal quantitative triggers are: (1) the 50-foot audibility rule for electronic sound-reproduction devices (clearly audible at 50 feet = prima facie violation) at all hours; (2) the 50-foot audibility rule for motor-vehicle amplification under NCO 201-1; and (3) the Chapter 190 (Land Use Code) HVAC / mechanical-equipment standard of 50 dBA daytime (7:00 a.m. - 8:00 p.m.) / 45 dBA nighttime (8:00 p.m. - 7:00 a.m.) at residential zoning district boundaries. New Hampshire has no statewide environmental noise dB code parallel to WAC 173-60. NH RSA 644:2 disorderly conduct is the statewide reasonableness backstop.

Key details: City General dBA Cap: None codified - reasonableness + enumerated examples. Portable / Electronic Audio Trigger: Audible at 50 feet from source = prima facie (Ch. 201). Vehicle Audio Trigger: Audible > 50 feet from vehicle (NCO 201-1) + NH RSA 266:59. HVAC / Mechanical Equipment Cap: 50 dBA day (7 a.m. - 8 p.m.) / 45 dBA night (8 p.m. - 7 a.m.) at residential zoning boundary (Ch. 190). State dBA Framework: None - NH has no statewide environmental noise dB code.

Operation of an electronic sound-reproduction device audible at 50 feet (prima facie under Chapter 201) - violation, fine not less than $100. Motor-vehicle amplification audible > 50 feet (NCO 201-1) - violation, fine not less than $100, often charged with NH RSA 266:59 muffler / equipment violation. Mechanical equipment exceeding the Chapter 190 50 dBA day / 45 dBA night residential-boundary cap is a Chapter 190 / Land Use violation enforceable by the Code Enforcement Department and Zoning Administrator. NH RSA 644:2 (disorderly conduct) is a violation up to $1,000; Class B misdemeanor up to 1 year if continued after desist order. Report to Nashua Police non-emergency 603-594-3500.

Outdoor Music

Outdoor music in Nashua is governed by Chapter 201 (Noise) - the disturbance / 50-foot audibility standard for electronic sound-reproduction devices applies citywide at all hours, with the public-street vocal bar 11:00 p.m. - 7:00 a.m. Permitted special events (the City of Nashua SummerFun concert series at Greeley Park Bandshell every Tuesday at 7 p.m., the Greater Nashua Pride Festival, downtown ArtWalk and Winter Holiday Stroll programs organized by Great American Downtown, and concerts at Holman Stadium) operate under city event permits. Park-system amplification is also governed by Chapter 215 (Parks and Recreation Areas).

Key details: Code Authority: Nashua Chapter 201 (Noise) + Chapter 215 (Parks and Recreation Areas) + city event-permit process. General Outdoor Amplification Standard: Citywide reasonableness + 50-foot audibility prima facie. Public Street Vocal Cutoff: 11:00 p.m. - 7:00 a.m.. Entertainment District Overlay: None. Major City Event Series: SummerFun at Greeley Park Bandshell, Tuesdays 7 p.m. (free admission).

Outdoor amplified music that disturbs neighbors - or is audible at 50 feet (prima facie under Chapter 201) - is a Chapter 201 violation, fine not less than $100, written cease/abate order, each day a separate offense. Public-street yelling, shouting, hooting, whistling or singing between 11:00 p.m. and 7:00 a.m. is also a Chapter 201 violation. Permit-condition violations (operating outside conditioned hours or exceeding conditioned amplification) trigger permit revocation, denial of future permits, and on-scene Nashua Police shutdown. Park-amplification violations are enforceable under Chapter 215 (Parks and Recreation Areas) by the Division of Parks and Recreation. NH RSA 644:2 (disorderly conduct) is a violation up to $1,000; Class B misdemeanor up to 1 year if continued after desist order. Nashua Police non-emergency 603-594-3500.

The Bottom Line

Compared to many U.S. cities, Nashua gives residents more room on noise ordinances. 2 of the 9 rules here are rated permissive. But permissive does not mean unregulated. There are still requirements, and the city does enforce them when violations are reported.

All of the above reflects Nashua's municipal code as of our last review. If you need specifics on fines, exemptions, or filing requirements, the detailed ordinance pages linked above have the full breakdown.
