Documentation & Compliance

Online Filing

All noise mitigation plans must be filed online and be available onsite. This ensures transparency and allows for quick access during inspections.

Inspection Readiness

Construction sites should be prepared to show these plans during inspections to avoid fines. Regular checks ensure that noise levels are within permissible limits.

Reporting Issues

Individuals or businesses affected by excessive construction noise can report the issues via 311 or an online report. This allows for timely intervention and mitigation.

Types of Noise Mitigation Plans

Construction Noise Mitigation Form

This form is used for general construction activities, outlining methods to minimize noise impact on the surrounding area.

Utility Noise Mitigation Form

Specifically designed for utility-related construction, this form addresses the unique noise challenges posed by these activities.

Interior Renovation Noise Mitigation Form

For interior construction activities, this form ensures that noise does not excessively disrupt neighboring units or properties.

Minimal Noise Mitigation Form

This form is targeted at activities with minimal noise impact, ensuring even minor disturbances are managed effectively.

Alternative Noise Mitigation Plans (ANMP)

When strict compliance with standard noise mitigation rules is not feasible, an Alternative Noise Mitigation Plan (ANMP) is required. These plans must be approved by the Department of Environmental Protection (DEP) before work can proceed.

Required Forms for ANMP

  • After Hours for Utilities and Street Work
  • Authorized Hours—Weekdays 7am to 6pm Form
  • Undue Hardship After Hours Construction Work Authorization Form

Vendor Guidance

Noise Control Products

Contractors can refer to city-provided guidance sheets for suitable noise control products, though these are suggestions and not endorsements.

Small Projects

Specific guidance is available for smaller construction jobs to help achieve compliance with noise regulations while maintaining project efficiency.

Noise Barriers Specifications

Perimeter Noise Barriers

These barriers must achieve a Sound Transmission Class (STC) rating of 30 or more and be well-constructed to avoid leaks or gaps, effectively blocking noise transmission.

Height and Structure

Noise barriers must be designed to block the line-of-sight between noise sources and receptors, and should be tailored to the specific requirements of the construction site.

Additional Resources

After Hours Construction Noise Protocol

This protocol provides specifics on noise measurement during after-hours inspections, ensuring transparency and adherence to the Noise Code.

Annual Report

For broader insights, the 2018 Annual Report and guidance from the National Institute for Occupational Safety and Health's Buy Quiet Program can be referenced. These documents provide valuable information on noise management strategies and compliance success stories.

Key Considerations


Ensure all plans and forms are up-to-date and filed correctly to avoid penalties. Regularly update noise mitigation plans to reflect current construction activities and site conditions.


Maintain onsite copies of noise mitigation plans and be prepared for inspections at all times. Proactive preparation helps minimize disruptions and ensures compliance.

Community Impact

Understand and mitigate the impact of construction noise on surrounding areas. Effective communication with the community can help manage expectations and reduce complaints.


Be ready to implement alternative noise mitigation plans when standard compliance is not feasible. Flexibility in approach helps address unique site challenges while adhering to regulations.

This condensed outline captures the essential regulations and practices surrounding construction noise mitigation in New York City, providing a solid foundation for a comprehensive understanding of the topic.
