Summary
Jersey City's noise code specifically names air conditioners and HVAC units as sound sources it regulates. Chapter 222 defines a 'multi-use property' to include buildings whose air conditioners may raise sound levels elsewhere on the same lot, and sets the measurement boundary for an outdoor HVAC unit at the exterior wall of the unit receiving the noise.
MULTI-USE PROPERTY means any distinct parcel of land that is used for more than one (1) category of activity. Examples include, but are not limited to: (1)A commercial, residential, industrial or public service property having boilers, incinerators, elevators, automatic garage doors, air conditioners, laundry rooms, utility provisions, or health and recreational facilities, or other similar devices or areas, either in the interior or on the exterior of the building, which may be a source of elevated sound levels at another category on the same distinct parcel of land... REAL PROPERTY LIKE means either: ...(c)On a multi-use property as defined herein, the vertical or horizontal boundaries between the two portions of the property on which different categories of activity are being performed (e.g., if the multi-use property is a building which is residential upstairs and commercial downstairs, then the real property line would be the interface between the residential area and the commercial area, or if there is an outdoor sound source such as an HVAC unit on the same parcel of property, the boundary line is the exterior wall of the receiving unit).
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 52).
Full Breakdown
Section 222-2's MULTI-USE PROPERTY definition lists 'air conditioners' among the equipment, along with boilers, incinerators, elevators, and laundry rooms, 'which may be a source of elevated sound levels at another category on the same distinct parcel of land,' covering buildings that mix residential, commercial, industrial, or public-service uses. and 50 dB(A) overnight, while Table II applies indoor limits of 55 dB(A) daytime and 40 dB(A) overnight where the HVAC unit and the receiving space share a wall, floor, or ceiling. 1 rather than at the property's outer boundary, a distinction that matters in condo and mixed-use buildings where the source and receptor sit on the same lot.
Violations & Fines
An HVAC noise complaint that exceeds the Table I or II limits is enforced the same as any other Chapter 222 violation: a noise control officer or investigator issues a notice of violation for a minor first offense or a notice of penalty assessment carrying a civil fine of up to $2,000 under N.J.S.A. 40:49-5 for a non-minor or repeat violation, with each continuing day a separate offense.
