NOISE REGULATION ACROSS MAJOR U.S. CITIES (2026)

This map visualizes how residential and commercial noise limits, nighttime restrictions, and enforcement penalties vary across the 30 most populous U.S. cities. To see the city information block, hover over the round dot.

Note 1: Daytime and nighttime indicate when different noise limits apply by area. Max dB(A) values show allowable sound levels for residential and commercial zones, with lower limits enforced at night.
Note 2: For some cities, specific numeric noise limits are not defined in local ordinances or were not publicly available at the time of review and are therefore shown as “Not specified” on the map.
Note 3: Some cities regulate noise using ambient-, background-, or audibility-based standards rather than fixed decibel caps.
Note 4: Listed fines represent the maximum civil penalty authorized for a first residential noise violation; enforcement practices may vary.
