In New York City’s first year of enforcement, 95% of building owners who filed emissions reports met the city’s new emissions goals under Local Law 97. Seven percent of owners missed the deadline; the city’s Department of Buildings is issuing fines and notices of deficiency.

Under LL97, “Certain affordable housing buildings have later reporting start dates in 2027 and 2036, depending on the applicable program. Some 11,000 properties, made up of almost 17,000 buildings, were required to report under Article 320 in 2025,” Joe Burns writes for Smart Cities Dive.

Of the properties required to report, 45% are multifamily housing, 17% are office spaces and 8% are either K-12 schools or non-refrigerated warehouses.
