NYC Noise Code regulates generator noise under the general prohibition (§24-218) and construction device provisions. After 10 PM, generator noise exceeding 7 dB(A) above ambient at a receiving property is unreasonable. Construction generators must comply with after-hours noise mitigation plans. Emergency generators during outages are exempt.
Generator noise in NYC is regulated under the general noise prohibition of Administrative Code §24-218 and specific construction device provisions. Portable and stationary generators producing sound that exceeds 7 dB(A) above ambient levels at a receiving property after 10 PM and before 7 AM constitute unreasonable noise. Construction generators operating after hours (6 PM to 7 AM weekdays, weekends) require an after-hours work permit from DOB and must comply with a noise mitigation plan, which may include sound barriers, exhaust mufflers, and equipment enclosures. Emergency generators operated during utility power outages are generally exempt from noise restrictions. Permanently installed backup generators in buildings must comply with DOB mechanical code requirements and the noise code when tested during non-emergency conditions. Generator testing is typically restricted to weekday business hours. DEP enforces generator noise complaints through 311-initiated inspections.
DEP noise violation summons. Fines starting at $1,050 for first offense. DOB violations for after-hours construction generator use without permit. Stop-work orders.
