Jackson County, MO Noise Ordinances: Quiet Hours (2026)

Jackson County is a charter county of the first class. Its substantive criminal-style ordinances live in Chapter 55 of the County Code (the 'Petty Offense Code of Jackson County, Missouri'), which applies in the unincorporated parts of the county. The county has no decibel chart and no fixed nighttime quiet-hours window of the type used by Kansas City (Chapter 46) or Independence; instead, conduct is judged against the state peace-disturbance standard. RSMo Section 574.010 makes it a misdemeanor to (1) unreasonably and knowingly make loud noise, or (2) knowingly produce noise that can be plainly heard inside another person's private property. Cases under 574.010 commonly involve loud parties, amplified music, vehicle stereos, or persistent shouting at night. Within Jackson County's incorporated cities, the city's own noise ordinance controls: Kansas City Code Chapter 46 sets specific dB(A) limits and a 10:00 p.m. to 7:00 a.m. nighttime period; Independence, Lee's Summit, Blue Springs, Raytown and Grandview each have their own quiet-hours ranges (typically 10 p.m. or 11 p.m. to 7 a.m.). Construction-noise, commercial, and industrial limits also vary city by city. For the unincorporated unincorporated areas, call the Jackson County Sheriff's Office for a noise disturbance; the deputy decides at the scene whether RSMo 574.010 has been violated.
