Chicago regulates aircraft noise primarily through O'Hare and Midway airport noise abatement programs administered by the Chicago Department of Aviation (CDA). The city has invested over $1 billion in residential sound insulation programs for homes near both airports.
The Chicago Department of Aviation manages the O'Hare Noise Compatibility Commission (ONCC) and the Midway Noise Compatibility Commission. Residential Sound Insulation Programs (RSIP) provide free sound insulation to eligible homes. Nighttime preferential runway use programs are in effect from 10 PM to 7 AM. The FAA sets federal noise standards under 14 CFR Part 150, which preempt local regulation of in-flight aircraft noise. Chicago Municipal Code Chapter 10-36 governs airports and empowers the Commissioner of Aviation to set operational rules.
Aircraft noise complaints are handled through the CDA noise monitoring system. Violations of airport operational rules are addressed through FAA enforcement. The city cannot directly fine airlines for noise but can impose operational restrictions through airport use agreements.
