Independence, MO Noise Ordinances: Quiet Hours (2026)

Section 7.10.004, in Chapter 7 Article 10 (Noise Control), makes it unlawful to make or cause any sound disturbance, or any excessive, unnecessary, or unusually loud sound, on public property. Subsection A.2 sets the City's clearest nighttime curfew: yelling, shouting, hooting, whistling, or singing on the public streets that is plainly audible between 11:00 p.m. and 7:00 a.m. is specifically declared a violation, regardless of whether it would otherwise disturb a reasonable person. The same subsection separately bars amplified sound (radios, TVs, loudspeakers, PA systems) audible 25 feet or more from the device at any hour, and bars unmuffled engine exhaust and sound near schools, churches, courts, or hospitals marked as sound-sensitive zones.

For private property, Section 7.10.006 imposes numeric nighttime limits by receiving land use: a continuous source in a residential district cannot exceed 50 dBA at the property boundary between 10:00 p.m. and 8:00 a.m. (versus 60 dBA in daytime hours), and commercial sources are capped at 62 dBA around the clock. Section 7.10.003 separately bans any sound disturbance on private property, day or night, that annoys or disturbs a reasonable person of normal sensitivities.

Enforcement is split by section: Section 7.10.012 assigns the Chief of Police to enforce Sections 7.10.003, 7.10.004, 7.10.005, and 7.10.007, while the Director of Health enforces the receiving-land-use table in 7.10.006. Section 7.10.011 sets the penalty at up to $500.00 and up to six months in jail, and expressly makes each day a violation continues a separate offense. An owner facing hardship can apply to the City Manager under Section 7.10.009 for a temporary permit; routine daytime yard work with gas-powered equipment (8:00 a.m. to 8:00 p.m.) and emergency vehicles are exempt under Section 7.10.008.
