Kendall County, IL Noise Ordinances: Decibel Limits (2026)

Section 24-23 of the Kendall County Noise Control Ordinance splits the day into two enforcement windows. , the ceiling drops to fifty-five (55) dBA. Both limits are measured, per Section 24-23(a)-(b), on the property line of the complainant, not inside the noise source's own property, and Section 24-23(c) declares any sound crossing those numbers a public nuisance. For attached multifamily buildings such as apartments, condos, and townhomes, Section 24-23(d) moves the measurement point to the outer property line of the whole building rather than the wall between individual units.

The article only reaches unincorporated residential zoning districts under Section 24-21, and it exempts several categories in Section 24-24, including emergency utility repairs, agricultural equipment on farmland, duly registered motor vehicles and motorcycles, sanctioned community events like parades and Fourth of July celebrations, and properly maintained residential equipment such as air conditioners, lawn mowers and snow blowers used within factory specifications. Measurement itself is defined in Section 24-22 as A-weighted sound pressure level, dB(A), read on a calibrated sound level meter. Complaints go to the County Sheriff's Office under Section 24-25, and the State's Attorney's Office prosecutes.

Section 24-27 sets fines of fifty to five hundred dollars for a first offense and one hundred to one thousand dollars for any repeat offense within two years, with each day of continuing violation counted as a separate offense.
