NYC Noise Code caps HVAC circulation devices at 42 dBA measured 3 feet from a neighbor window. Rooftop condensers common on Queens apartment buildings must comply with property-line limits.
HVAC equipment noise in Queens County is regulated under NYC Administrative Code 24-227 and the general NYC Noise Code. Circulation devices including window AC units, split-system condensers, and rooftop HVAC may not exceed 42 dBA measured 3 feet from a neighbor bedroom or living room window, or exceed 7 dBA above ambient at any residential property line. For multi-family buildings common across Queens (Rego Park, Forest Hills, Jackson Heights), rooftop condensers must be set back, screened, or vibration-isolated to meet decibel thresholds. Existing equipment installed before Noise Code amendments must be brought into compliance upon replacement or major repair. NYC Department of Buildings (DOB) sign-off is required for new installations including noise mitigation calculations. DEP issues Notices of Violation with fines from 440 to 8,000 dollars for non-compliant equipment. Complaints go through 311 with time and location details. Tenants can request a landlord inspection through HPD if building equipment is the source.
