Noise from Specific Sources in Yonkers, NY

If you live in Yonkers or are thinking about moving there, noise from specific sources are one of those things you probably won't think about until they affect you directly. Yonkers has 5 specific rules on the books covering different aspects of noise from specific sources, and some of them might surprise you.

HVAC & Mechanical Noise

Ground-based air-conditioning and heating equipment on new downtown Yonkers buildings can only go in the rear or interior side yard, at least five feet from any lot line, and never in a front or side-front yard. The zoning code also requires that equipment comply with the city's separate Noise Ordinance in Chapter 66.

Key details: Ground-based HVAC location: Rear or interior side yard only. Minimum lot-line setback: 5 feet. Front/side-front yard placement: Prohibited. Also required: Compliance with Chapter 66 Noise Ordinance. Applies to: Downtown districts (Article XVIII).

A condenser or heat pump installed in a front or side-front yard, or closer than five feet to a lot line, fails § 43-223E(4) and can hold up building permit sign-off or certificate of occupancy for downtown construction until it is relocated or screened to comply. Equipment that also produces a noise disturbance can separately draw enforcement under Chapter 66, independent of the siting violation.

Car Alarm Limits

Yonkers City Code § 66-4E bars a motor vehicle's exterior alarm from sounding more than five minutes continuously or 10 minutes intermittently, and separately bans shaker switches or other devices that trigger false alarms. § 66-6D exempts a properly functioning burglar alarm that shuts off within 15 minutes of activation.

Key details: Alarm limit: 5 min continuous / 10 min intermittent max. Governing section: Yonkers City Code § 66-4E. Related exemption: § 66-6D: 15-min shutoff exempts alarm sound. Also barred: Shaker switches that trigger false alarms. Penalty: Class II offense, $100-$5,000 or 15 days jail.

A vehicle alarm that sounds continuously for more than five minutes or intermittently for more than 10 minutes violates § 66-4E, a Class II offense under § 66-24. Equipping a vehicle with a shaker switch that triggers false alarms is a separate violation of the same subsection. Under § 1-21, penalties run $100 to $5,000 or up to 15 days in jail, or a $250 to $5,000 civil penalty.

Bar & Nightclub Noise

Yonkers' Zoning Ordinance imposes noise-containment standards on cabarets and nightclubs beyond the general Chapter 66 noise limits. City Code § 43-36D sets minimum setbacks from residential property, requires sound-insulated interiors, confines entertainment to fully enclosed buildings, bans outdoor PA and music systems, and requires a Chapter 23 cabaret license.

Key details: Setback from residential use: 50 feet minimum. Setback from residential district line: 100 feet minimum. Outdoor PA/music system: Not permitted. Entertainment location: Fully enclosed building only. Outdoor dining: Prohibited for these uses.

Operating a cabaret or nightclub that fails the § 43-36D setback, sound-insulation, enclosed-building or no-outdoor-sound standards is a zoning code violation, enforced through the Department of Housing and Buildings' site-plan and use-compliance process rather than a fixed statutory fine. Because Subsection D(5) conditions the use on holding a valid Chapter 23 cabaret license, an operator out of compliance with the zoning standards also risks that license's continued validity.

Compared to other cities, Yonkers takes a harder line on bar & nightclub noise. The enforcement and penalty structure reflects that.

Delivery Truck Noise

Loading and unloading boxes, crates, containers or drums between 10:00 p.m. and 7:00 a.m. is a noise-code violation in Yonkers if it creates a noise disturbance across a residential property line, and delivery trucks idling more than five minutes an hour within 150 feet of a residential area face a separate ban.

Key details: Loading/unloading noise curfew: 10 p.m. to 7 a.m.. Truck idling limit: 5 minutes per 60-minute period. Idling ban radius: within 150 feet of residential area. Enforced by: noise control officer or police officer. Section D last amended: 6-25-2025 by Ord. No. 11-2025.

A violation of Chapter 66 is a Class II offense under § 66-24 and City Code § 1-21, punishable by a $100 to $5,000 fine or up to 15 days in jail, plus a $250 to $5,000 civil penalty. A noise control officer or police officer can issue an abatement order under § 66-22 requiring the noise to stop within a set time, and ignoring that order draws its own appearance ticket under § 66-23.

Generator Noise

Yonkers City Code § 66-6J exempts emergency generators used during a power failure from Chapter 66's noise disturbance restrictions entirely. No decibel cap, curfew or permit applies to a generator running because the power is out, unlike the hourly and time-of-day limits that govern most other equipment in the chapter.

Key details: Exemption: Full exemption during an actual power failure. Governing section: Yonkers City Code § 66-6J. No cap applies: No dBA limit or curfew while exempt. Ends when: Power restored; then covered by § 66-3. Status: Not regulated during genuine outage use.

There is no Chapter 66 violation for running an emergency generator during a power failure; § 66-6J removes it from enforcement entirely. If the generator keeps running after power is restored for a non-emergency reason, the exemption ends and the general noise-disturbance prohibition in § 66-3 and the Class II penalty in § 66-24 apply instead, meaning a fine of $100 to $5,000 or up to 15 days in jail under § 1-21.

The rules around generator noise in Yonkers lean permissive, but that does not mean anything goes.

The Bottom Line

Yonkers's noise from specific sources rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Yonkers is broadly strict or permissive.
