The Short Version
Chicago sets quiet hours from 9 PM to 8 AM. The ordinance uses both a "reasonable person" standard and specific decibel limits: 55 dB at night in residential areas, 60 dB during the day. What makes Chicago's approach distinct is the aldermanic involvement — your local alderperson's office often handles noise complaints before they reach formal enforcement. The Chicago Department of Public Health oversees the ordinance but the police department responds to immediate complaints. Fines start at $300 and can reach $1,000 for repeat offenders.
Full Breakdown
Chicago's Environmental Noise Ordinance (Municipal Code 11-4-2800) establishes both quantitative decibel limits and qualitative standards. The 55 dB nighttime limit in residential areas is measured at the property line. During the day, 60 dB is the ceiling. But the city also uses a "disturbing the peace" standard that doesn't require a meter — if it's unreasonably loud, officers can act.
Chicago's aldermanic system means your local ward office is often the first stop for noise issues. Aldermen can mediate between neighbors, pressure landlords to deal with noisy tenants, and escalate persistent problems to city enforcement. This informal system handles many complaints before they become official.
The Department of Public Health regulates commercial and industrial noise sources, including bars and restaurants. Establishments with entertainment licenses face separate, more specific sound limits. The city has also been expanding enforcement of noise from late-night venues in neighborhoods like Wicker Park and Logan Square where residential and nightlife uses are in close proximity.
What Happens If You Violate This?
Fines start at $300 for first offenses and go to $1,000 for subsequent violations. Commercial establishments face fines of $500-$2,000 and potential license review. The city can also issue cease-and-desist orders for chronic noise sources.
