Local Law 84 of 2009 (NYC benchmarking)
New York City’s annual energy and water benchmarking requirement for applicable buildings. The current covered-building requirements and reporting instructions determine the owner’s obligations.
New York City jurisdiction · Sources checked September 15, 2026. Law numbers repeat by year. These educational summaries are not legal advice or a complete compliance checklist. Later amendments, agency rules, building characteristics, and effective dates determine the requirements for a particular property. Use the linked City sources to confirm current obligations.
Why it matters
The work starts with complete property and utility information. Benchmarking is a reporting process, not an energy audit or an emissions-compliance determination. Confirm current applicability and submission requirements for the property rather than relying on a prior year’s assumptions.
In practice
A project example
A change in property configuration or meter coverage may require corrections to the benchmarking record before the next submission.
