Full Breakdown
Under Sec. 17-25, Rockford adopts by reference the Illinois Pollution Control Board's numeric sound emission standards for property-line noise sources (35 Ill. Admin. Code 901.101 et seq.), the same rules used statewide to police industrial and commercial noise crossing a property line. Sec. 17-26 separately bars any noise that unreasonably disturbs neighbors, weighing proximity to sleeping areas, land use, time, and duration. Sec. 17-34 bars licensees from running a baler, crane, pneumatic hammer, or derrick before 7:00 a.m. or after 10:00 p.m. Code enforcement and police investigate complaints; violations carry the Code's general $50-$750 fine, with each day of a continuing violation a separate offense under Sec. 1-9.
Violations & Fines
Violating the property-line noise standard or equipment curfew draws a $50-$750 fine per Sec. 1-9; each day of a continuing violation is a separate offense, and nuisance-noise devices can be seized under Sec. 17-37.
