NYC Benchmarking Help Center

The NYC Benchmarking Help Center is the one stop shop for information, assistance, and answers to your questions about the NYC Benchmarking Law.

Trained staff will walk you through benchmarking steps, directly provide or point you to training and informational resources, and help you resolve problems so that you can meet the May 1 deadline with time to spare. You can send your questions to, or call 212-566-5584.

Alternatively, you can fill out this Contact Form.

Department of Finance

If you believe your building should or should not be on the Covered Buildings List, please email the Department of Finance (DOF) at to dispute building square footage or the number of buildings on a tax lot for both the NYC Benchmarking Law and the NYC Energy Audits and Retro-commissioning Law (LL87) lists. This is also where you can report a change of ownership during the benchmarking year.

Email and include in your email the following:

  • The building(s) borough, block and lot numbers
  • Contact name
  • Contact email address or telephone number
  • Reason for dispute

Department of Buildings

To reach the Department of Buildings for questions related to enforcement and violations, please email with your building's identification information (including BBL, BIN, address, and/or violation number) and a short description of your question. This is also where you can question the requirement to benchmark for buildings that have an active Demolition or New Building permit, or do not have a Certificate of Occupancy.

Department of Environmental Protection

All inquiries about water benchmarking should be directed to the Department of Environmental Protection at
