Noise from Specific Sources in Mount Vernon, NY

If you live in Mount Vernon 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. Mount Vernon has 4 specific rules on the books covering different aspects of noise from specific sources, and some of them might surprise you.

Delivery Truck Noise

Mount Vernon's noise ordinance specifically outlaws unreasonably loud loading and unloading noise, including slamming crates, boxes and containers during a delivery. It's one of sixteen named acts the Noise Control Ordinance treats as an automatic violation.

Key details: Prohibited act: Unreasonably loud loading/unloading noise. Also covers: Opening/destroying bales, boxes, crates. Enforced by: Mount Vernon Police Department. Maximum fine: $1,000 per day of violation. Maximum jail: 15 days.

A violation of § 178-4B(9) is punishable under § 178-4.18 by a fine of up to $1,000, up to 15 days in jail, or both, with each day the violation is committed or continues treated as a separate offense. The Police Department can issue an immediate cease-and-desist order under § 178-4.17.

Car Alarm Limits

Mount Vernon bars auto shops from testing car alarms within 100 feet of a residential zoning district by sounding them openly. Testing is only allowed indoors with doors and windows closed, or with a muffler fitted to the alarm.

Key details: Ban radius: Within 100 ft of residential zoning. Exception 1: Testing indoors, doors/windows closed. Exception 2: Muffler fitted to the alarm. Audibility test: 50 ft away = prima facie violation. Maximum penalty: $1,000 fine or 15 days jail per day.

A violation of § 178-4B(15) is punishable under § 178-4.18 by a fine of up to $1,000, up to 15 days in jail, or both, with each day of continued violation a separate offense. The Police Department can order an immediate cease-and-desist under § 178-4.17 and, with a judicial order, seal the offending equipment.

Compared to other cities, Mount Vernon takes a harder line on car alarm limits. The enforcement and penalty structure reflects that.

HVAC & Mechanical Noise

Mount Vernon caps continuous noise crossing the property line from any air-conditioning or air-handling device in residential zones at 55 db(A), under § 178-4.9 of the Noise Control Ordinance. The limit does not apply if the unit raises the ambient sound level by less than 5 db(A), sparing quiet equipment installed in already-loud settings from enforcement.

Key details: Residential noise cap: 55 db(A) at the property line. Measurement point: Any point beyond the property line. De minimis exemption: Increase under 5 db(A) over ambient noise. Enforcing agency: City of Mount Vernon Police Department. Maximum penalty: $1,000 fine or 15 days jail, per day.

A property owner or installer who exceeds the 55 db(A) property-line limit for air-conditioning or air-handling equipment is subject to the general Chapter 178 penalty in § 178-4.18: a fine of up to $1,000, imprisonment of up to 15 days, or both, with each day the excess noise continues charged as a separate offense.

Bar & Nightclub Noise

Mount Vernon bans any restaurant, bar, cafe, discotheque or dance hall from running sound at or above 95 db(A) for more than 30 seconds at the spot where patrons sit, under § 178-4.12 of the Noise Control Ordinance. The limit is measured at the location of the spectators, not at the property line, making it enforceable from inside the venue itself.

Key details: Sound limit: 95 db(A) for more than 30 seconds. Covered venues: Restaurant, bar, cafe, discotheque, dance hall. Measurement point: Location of the spectators inside the venue. Enforcing agency: City of Mount Vernon Police Department. Maximum penalty: $1,000 fine or 15 days jail, per night.

Operating a restaurant, bar or nightclub above the 95 db(A), thirty-second threshold violates § 178-4.12 and is punishable under § 178-4.18 by a fine of up to $1,000, imprisonment of up to 15 days, or both. Each night the venue exceeds the limit is a separate offense, so repeat violations at the same location compound quickly.

The Bottom Line

Mount Vernon'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 Mount Vernon is broadly strict or permissive.
