How to Comply With New York Local Law 84


 Are you a property owner in New York City? Are you worried about Local Law 84 or its compliance deadline? If so, read our guide on Local Law 84 (LL84).

What is New York Local Law 84 Compliance all about?

New York Local Law 84 is legislation that forms part of the existing energy laws. This law was passed in 2009, and covers buildings larger than 50,000 square feet within New York City. LL84 directs owners and managers of the affected building to send an annual report to the city. This report details energy and water consumption in a process called benchmarking.

 Other buildings that qualify are:

  • Two or more buildings built on the same tax lot and covering more than 100,000 square feet
  • Starting in May 2018, buildings between 25,000 and 50,000 square feet must also benchmark for the first time.

 What are Local Law 84 Requirements?

  • Collecting data about the energy consumption rates from the various venders, e.g., National Grid, and fuel and oil providers.
  • Providing the buildings energy consumption data into the city website
  • Giving estimates of missing energy data by extrapolating the estimates
  • Coming up with an energy usage document with all the required details
  • Opening an account with the EPA’s Portfolio Manager website
  • Handing in the final report online to the city of New York.

 All benchmarking data is usually in the public domain. After being received by the U.S Environmental Protection Agency (EPA), this data is analyzed in reports. From here, the authorities then proceed to publish it in the New York City Energy and Water Performance map. This means that anyone can comfortably scrutinize whatever information that has been displayed in the Energy and Water performance map.

After the publishing of this report in the Energy and Water performance map, this report is included in the energy efficient policy development. This process under the Local Law 84 New York will also be included in other reports, e.g., the Building Technical Working Group report. 


Finally, the report is utilized in developing other resources within the City. Some of these resources include the New York City Retrofit Accelerator, Community Retrofit New York City amongst others. All these efforts are geared towards helping property owners to reduce their use of energy and save on monetary resources. There is more information on the NYC Benchmarking Law website.

How to know you are covered under local law 84

The local law compliance starts with knowing if you are required to benchmark your building. To get these details, you are required to your property tax amount from the state department of finance. You can also check a list on the GGBP website. The Department of Finance sends notifications to buildings required to comply. The State Department of Finance may also use notifications. They can notify building owners covered under this law so that appropriate action is taken. In cases where there are problems email Benchmarking@finance.nyc.gov to get help.

The email you send to the finance department should have the following:

  • Your name as the property owner
  • The building's borough, block, and the lot number
  • Contact email address
  • The dispute you have against the notification 

Compliance and violations

To comply with LL84, perform an annual analysis of your annual energy use. This then must be submitted to the authorities under the Benchmarking report. According to the Local Law 84 guide, you are required to submit this report by May 1st. Failure to file is a $500.00 penalty.

 How to Challenge Violations

You are free to challenge any violations the city issues. Fill out a Benchmarking Violation Challenge Form and email it to: sustainability@buildings.nyc.gov . The physical address is on the department’s website. 

We advise all property owners and those involved in this sector to comply so as to have their structures protected under law. There are plans to have buildings covering between 25,000 and 50,000 included under this law from 2018.  If you're curious about Local Law 87, read our blog post on how to comply.
