Nashua, NH Noise Ordinances: Quiet Hours (2026)

Nashua, NH (population ~91,000, the second-largest city in New Hampshire and seat of southern Hillsborough County on the Massachusetts border) regulates noise primarily through Chapter 201 (Noise) of Part II General Legislation of the Revised Ordinances, adopted by the Board of Aldermen on August 9, 2005 by Ordinance O-05-96. New Hampshire is a Dillon's Rule home-rule state where cities derive noise-regulation authority from RSA 31:39 (towns/cities may regulate for public health and safety) and RSA 47:17 (cities' general police-power grant; Nashua is a city under RSA 47). Unlike Washington's WAC 173-60 statewide dBA matrix, New Hampshire has no statewide environmental noise code, so each municipality operates under its own ordinance plus the statewide disorderly-conduct backstop at RSA 644:2. Chapter 201's principal substantive provisions include: (1) the public-street rule at 11:00 p.m. - 7:00 a.m. prohibiting yelling, shouting, hooting, whistling, or singing on the public streets (or at any time so as to annoy or disturb the quiet, comfort or repose of persons in neighboring premises); (2) the electronic sound-reproduction rule barring the use of 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 location is prima facie evidence of violation; (3) the commercial-advertising rule barring use of such devices cast upon the public streets for commercial advertising or to attract attention to a building; (4) the school / institution / hospital / court rule barring creation of any unreasonable or excessive noise on streets adjacent to a school, learning institution, church, court, or hospital when in use, where conspicuous signs are posted; and (5) the motor-vehicle audio rule at NCO 201-1 barring operation of an electrically amplified sound system in or on a motor vehicle so as to produce sound clearly audible more than 50 feet from the vehicle. Emergency operations under direction of local officials are exempt under § 201-2. RSA 644:2 disorderly conduct is the statewide backstop - it is a violation (up to $1,000 fine) for loud or unreasonable noises in a public place, or in a private place which can be heard in a public place or other private places, that would disturb a person of average sensibilities. RSA 644:2 escalates to a Class B misdemeanor (up to 1 year in jail) if conduct continues after the defendant is told to desist. Active disturbances route to the Nashua Police Department at 603-594-3500 (non-emergency). Nashua's downtown Main Street corridor (the historic mill-era center with bars and restaurants from Park Street to Pearl Street), the dense triple-decker and multifamily blocks of French Hill and the Crown Hill / Tree Streets neighborhoods, and the apartment concentrations near Daniel Webster College and Rivier University drive the most consistent NCO 201 complaint volume.
