Local Law 97
Local Law 97 is part of New York City's 2019 Climate Mobilization Act. The law aims to reduce emissions from the city's largest buildings by 40% in 2030 and reach net zero by 2050. As a key component of the city's Green New Deal, the law was established to achieve ambitious sustainability targets.
Local Law 97 generally covers:
Buildings that exceed 25,000 gross square feet (GSF)
Two or more buildings on the same tax lot that together exceed 50,000 sq. ft.
Two or more buildings owned by a condominium association that are governed by the same board of managers and that together exceed 50,000 square feet.
Article 320 of Local Law 97, corresponding with rule 1 RCNY §103-14 , applies to most covered buildings. Compliance pathways vary based on building characteristics, with affordable housing being a key differentiator. Single buildings follow one of five pathways, while multiple buildings on a lot follow one of seven compliance pathways.

Compliance Pathways
Reporting Due Dates
Starting in 2025, most compliance pathways must submit an annual Local Law 97 compliance report by May 1st, detailing emissions and limits from the previous calendar year. A grace period until June 30th allows submission without penalties, but reports filed after this date incur a $0.50/sf monthly penalty from May 1st onward. It is recommended to include calculations and floor area diagrams with the report, as the Department may request supporting documentation at any time.
For the 2026 Pathway the annual filing begins May 2027 and the 2035 Pathway annual report filing starts in May 2036.
First Local Law 97 Compliance report deadline is May 1, 2025
