Full Breakdown

New Haven's noise ordinance doesn't single out bars or nightclubs; it regulates by zone. A bar or club operating in a commercial district (BA, BB, BC, BD, BD-1, BE) falls under Sec. 18-75(b)(2), which caps the noise it may send past its property line at 62 dBA into another commercial or industrial zone, 55 dBA into a residential zone during daytime hours, and 45 dBA into a residential zone at night. Amplified music or crowd noise plainly audible from 100 feet away can also be cited under the article's general audibility standard in Sec. 18-74.

Violations & Fines

Fine up to the state-law maximum per violation under Sec. 18-82, and each day the noise continues over the limit counts as a separate offense.
