You are allowed to conduct construction on your property between 7am and 6pm on weekdays. At all other times, including anytime on the weekends, you must apply for after-hours authorization. Any person or business doing construction in the city must develop a Construction Noise Mitigation Plan before the start of construction or renovation. You will need to check off that you have a Construction Noise Mitigation Plan in your Department of Buildings application for a construction permit. If you are seeking an after-hours construction permit with the Department of Buildings or Department of Transportation (also known as a variance), you must have your Construction Noise Mitigation plan already in place.
You do not have to file your plan with DEP, but it must be available on site in case we inspect your business or property. To avoid fines, be sure that your contractor(s) is aware of these construction activity requirements. If nearby construction impacts you or your business, call 311 or file a report online. For general noise information, visit New York City Noise Code.
NOTE: All Construction Noise and Alternative Noise Mitigation Plans must be filed online using the forms listed on this page.
Construction Noise and Minimal Noise Rules
These rules establish a unique noise mitigation plan for each construction site, offering alternatives for contractors to continue their important construction tasks while having less noise impact on the surrounding environment.
The minimal noise rule provides a list of construction activities with minimal noise impact as well as specific noise mitigation procedures that must be implemented whenever the listed construction activities take place.
Construction Noise Contact Sheet
All contractors should have the Construction Noise Contact Sheet posted on a fence outside their construction site.
Construction Noise Mitigation Form
In accordance with Section 24-220 of the New York City Administrative Code, any individual or entity performing construction work in the city, shall adopt and implement a noise mitigation plan for each construction site when any device or activity is conducted as defined in Section 24-219. The attached sample form of a noise mitigation plan is intended to inform the user of the required plan elements that a responsible party must include when the listed devices are being used on site, and the mitigation strategies and best management practices that are being employed as defined in 15RCNY Section 28-102.
Construction Noise Alternative Mitigation Form
When required by Section 24-221 of the Administrative Code and or 15 RCNY Section 28-104, a complete and accurate Alternative Noise Mitigation Plan (ANMP) must be filed when strict compliance with the noise mitigation rules is not possible. When an ANMP is required, all construction activities that fall under it must be postponed until it is filed and approved by the DEP. After review and approval by DEP's technical staff, the plan must be readily posted at the job site.
Vendor Guidance For Smaller Construction Jobs
The following is intended to provide guidance to construction contractors with respect to finding and selecting suitable noise control products used on smaller construction jobs. These products and vendors may be helpful to contractors for achieving compliance with the New York City Noise Regulations.
Construction Noise Control Products and Vendor Guidance Sheets
The following is intended to provide guidance to construction contractors with respect to findings and selecting suitable noise control products. These products and vendors may be helpful to contractors for achieving compliance with the New York City Noise Regulations. These items are provided only as suggestions for contractors to consider and should not be construed as an official endorsement of any product and/or vendor by the City of New York. Contractors are free to choose other products/vendors that meet the requirements of such Code. This sheet will be updated from time to time as new noise control technologies gain acceptance.
After Hours Construction Noise Protocol
LL 53 of 2018 requires DEP to publish on the city’s website the manner by which noise levels shall be measured during after hours inspections. The Noise Code already requires readings to be taken in LMAX with the sound level set to slow response. This protocol provides more detailed guidance so the public is aware of the manner in which inspections are conducted.
