Local Law 154: NYC's All-Electric New Buildings Law

Groundbreaking legislation phases fossil fuels out of new construction starting in 2024

On December 15, 2021, the New York City Council passed legislation to phase fossil fuels out of new construction starting in 2024. With Local Law 154, New York City will become the largest city in the world to phase fossil fuels out of new construction. This law means new buildings, with few exceptions, will be all-electric and emit less carbon, all while improving local air quality and making occupants more comfortable.

Urban Green Council helped shape the law, including as lead witness testifying at the City Council hearing on November 17, 2021. Read Urban Green’s written testimony to see how our recommendations were incorporated into the final law.

“Furnaces, boilers and hot water heaters cause more carbon emissions in NYC than all uses of electricity combined,” said John Mandyck, CEO of Urban Green Council. “NYC continues to lead the way with transformational steps toward cleaner, healthier and low-carbon buildings.”

For a closer look at the law and its implementation timeline, read our summary. And make sure to read our latest report, Grid Ready, to see how NYC's grid can support this large-scale transformation to all-electric buildings.


  • Sets CO2 limits that effectively prohibit fossil fuel systems in new buildings and gut renovations
  • Phases in requirements starting with lower-rise buildings in 2024 and taller buildings in mid-2027
  • Allows more time for affordable housing and hot water systems in buildings other than one- and two-family homes
