Southborough, MA Public Conduct: Loud Party Ordinance (2026)

Southborough has no separate party or social-host bylaw. Chapter 130 contains no provision on parties or hosts by name, so a loud gathering is handled under the noise bylaw adopted 5-4-2022. Two provisions do the work.

Section 130-3(A) makes it unlawful for any person to create any loud noise, or to allow the creation of any loud noise, on property owned, leased, occupied or otherwise controlled by that person, when it causes an unreasonable disturbance beyond the property line that disturbs the peace. The words "allow the creation" mean the rule reaches a person who permits the noise on controlled property, not only the person making it.

Section 130-4(A) adds the nighttime rule: yelling, shouting, whistling, singing, playing music or making loud noises so as to annoy or disturb the reasonable quiet, comfort or repose of identified persons is prohibited between 11:00 p.m. and 7:00 a.m. when it generates an unreasonable disturbance.

Other provisions sit nearby. Noise audible beyond the property line while loading or unloading trucks is barred between 9:00 p.m. and 7:00 a.m. under § 130-4(D). Any establishment with a liquor license cannot let noise be distinctly audible beyond its premises between 9:00 p.m. and 7:00 a.m. under § 130-4(G). Distinctly audible means any sound that can be understood by a person using unaided hearing, such as discernable words or instrumentation. Section 130-5(E) exempts parades, public gatherings or events for which appropriate permits or licenses have been issued or which are constitutionally protected, and § 130-7(D) lets the Select Board grant temporary exceptions of no more than three days. Chapter 131 separately bars indecent and disorderly conduct near any dwelling house with intent to annoy or disturb any inhabitant.
