Quiet hours in Bronx County, NY — also called the noise ordinance, nighttime noise rules, or residential quiet time — define the hours during which excessive noise is prohibited.
The Bronx follows the NYC Noise Code (NYC Admin Code Title 24, Ch. 2), one of the most detailed noise codes in the country. Interior residential limit is 45 dBA between 10 PM and 7 AM, enforced by DEP and NYPD via 311 complaints. Bronx County has no separate county government; all noise complaints go through NYC agencies.
NYC Admin Code §24-218 sets interior residential sound limits of 45 dBA measured from inside a neighboring dwelling between 10 PM and 7 AM, and 45 dBA at any time when measured more than 3 feet from the source inside another dwelling. Outdoor ambient limits are measured 15 feet from the source. DEP inspectors respond to recurring complaints; NYPD handles immediate unreasonable noise under §24-218. Penalties for first offense residential noise start at $70 and escalate to $875 for commercial establishments. Dense Bronx neighborhoods like Fordham, Mott Haven, and Pelham Bay generate heavy 311 volume. Yankee Stadium events and Bronx Terminal Market commercial activity trigger special entertainment-area rules.
First residential violation: $70-$350. Commercial establishment: $350-$875. Repeat offenders within 18 months face doubled fines and potential OATH Environmental Control Board hearings.
