How NYC's General Noise Thresholds Work

NYC Administrative Code §24-218 prohibits unreasonable noise. For non-impulsive sound from a device, the general threshold is measured relative to the ambient sound level at the receiving property or at least 15 feet from the source on a public right-of-way.

Source-specific sections can replace the general §24-218 thresholds. Construction devices and activities are also excluded from §24-218 and follow separate requirements.

General §24-218 Reference Points

  • 10 PM - 7 AM: non-impulsive device sound is included when it measures 7 dB(A) or more above the ambient sound level
  • 7 AM - 10 PM: non-impulsive device sound is included when it measures 10 dB(A) or more above the ambient sound level
  • Impulsive sound: the reference threshold is 15 dB(A) or more above ambient, using the measurement settings specified by the code

Why 42 dB(A) and 45 dB(A) Are Not Universal Apartment Limits

The code uses 42 dB(A) and 45 dB(A) in specific provisions, including circulation devices and commercial music. Those figures should not be applied automatically to neighbor voices, televisions, construction, or every other sound source. The source type, measurement location, time, meter response, and ambient level all matter.

Construction Hours and Mitigation

NYC DEP states that construction is generally allowed from 7 AM to 6 PM on weekdays. Work at other times, including weekends, requires after-hours authorization, and construction or renovation work must have the required noise mitigation plan. NYC311 lists limited exceptions, including certain weekend repairs to existing owner-occupied one- or two-family dwellings, and says noise can still be reported when a site has a variance.

DOB's After Hours Variance Map can show whether a project has authorization to work outside normal hours. A variance does not establish that every level or type of noise is acceptable.

Use the Official NYC311 Complaint Category

NYC311 says the complaint process depends on the location and type of noise. Use its official Noise Complaints directory or call 311, then choose the category that matches the observed source, such as neighbor, construction, commercial music, equipment, or vehicle noise. The official form controls which information is required and which agency receives the Service Request.

For a neighbor-noise request, NYC311 currently says NYPD officers respond within eight hours when they are not handling emergencies and can take action if the noise is still happening when they arrive. This is a stated process, not a guaranteed response time or outcome. Call 911 for danger or the emergency conditions identified by NYC311, not for a routine noise record.

Official Request vs. Supplemental Record

NYC311 creates and routes the official City Service Request. SilentProof can separately organize timestamps, duration, location context, notes, recurring patterns, and reference sound levels into a PDF for landlord or follow-up use. These additions are not a universal list of NYC311 requirements.

SilentProof does not submit, update, or track an NYC311 complaint; determine whether the Noise Code was violated; replace an official or certified meter; or guarantee inspection, enforcement, or acceptance of a report.
