Berwyn, IL Noise from Specific Sources: Bar & Nightclub Noise (2026)

Berwyn does not print a separate noise chapter for bars and nightclubs. The controlling text is split between the licensed-premises rules and the general peace-disturbance chapter. Section 804.31(H) covers patios of establishments with an outdoor patio dining license: music from inside the establishment can be heard on the patio, and televisions are allowed, but the sound level must comply with the requirements of the code's Prohibited Noises section. That cross-reference is printed in § 804.31(H) as § 660.02(B), while the section actually titled Prohibited Noises in the exported code is § 666.02 in Chapter 666, Peace Disturbances.

Section 666.02 opens with a broad ban on loud, unnecessary or unusual noises or noises which annoy, disturb, injure or endanger the comfort, repose, health, peace or safety of others in the city. Division (B)(1) targets radios, musical instruments, stereos and any other sound device that disturbs the peace, quiet and comfort of the neighboring inhabitants, or that runs at any time with louder volume than is necessary for convenient hearing by the voluntary listeners in the room. For a bar the practical test is the neighbors, not the patrons. Division (B)(2) adds a 75 foot audibility test for sound devices on the public way or in a motor vehicle on it. Division (C) separately bars yelling, shouting, hooting, whistling or singing on public streets, particularly between 11:00 p.m. and 7:00 a.m., so as to annoy the quiet, comfort or repose of persons in the vicinity, which reaches crowds spilling out of a bar. Section 666.01 also bars using or permitting a building or premises for any business or recreation whose boisterous nature disturbs or destroys the peace of the neighborhood.

On the license side, § 804.31(F) closes a patio at 12:00 a.m. Sunday through Thursday and 1:00 a.m. Fridays and Saturdays, and § 804.31(P) makes the licensee solely responsible for the conduct of its patrons.
