New York Mandates All-Electric New Buildings to Cut Emissions

New York has become the first U.S. state to mandate that all new buildings be powered entirely by electricity, banning the use of gas or other fossil‑fuel hookups. The rule, finalized by the State Fire Prevention and Building Code Council in late July 2025, takes effect for new construction approved after December 31, 2025. Residential buildings up to seven stories and commercial or industrial structures up to 100,000 square feet must comply by that date; larger commercial or industrial buildings will be required to be all‑electric by 2029.

The All‑Electric Buildings Act was originally passed by the New York State Assembly in 2023. It was challenged by building and fossil‑fuel groups but a U.S. District Court ruling in July 2025 allowed the state to move forward. Industry groups have asked the U.S. Department of Justice to block the rule, but it remains in force for now. The law is designed to curb emissions from the built environment, which accounts for 31 % of all greenhouse‑gas emissions in the state.

The new mandate requires the installation of electric heat pumps, electric stoves, and other electric‑powered systems in place of gas appliances. It also includes a range of exemptions. Agricultural buildings, medical facilities, crematoriums, laboratories, restaurants and other specific facility types that meet certain criteria are exempt. The rule is expected to reduce energy use in New York homes by about 17 %, saving residents nearly $5,000 per household over 30 years. According to the New Buildings Institute, building decarbonization could also save money during construction, with 100 % electric single‑family homes projected to cost $7,500 to $8,200 less than conventional homes.

“The fossil fuel industry was sent a powerful message by the court in this case — the health, well‑being, affordability, and prosperity of our communities matters more than the industry’s profits and the hollowness of its fear‑mongering,” said Dawn Wells‑Clyburn, executive director of PUSH Buffalo. “The AEBA remains a powerful victory in the fight for our lives.”

Alex Beauchamp, Northeast region director at Food & Water Watch, told reporters, “When New Yorkers come together… we can win even in the face of opponents with an almost‑limitless budget. That is how we won this bill. It’s also how we are going to continue the fight to get fossil fuels out of all the existing buildings in the state.”

The law’s passage follows a broader national trend toward electrification of the built environment. By banning fossil fuels in most new buildings, New York is setting a precedent that could influence other states. The rule also addresses air quality concerns by reducing indoor and outdoor emissions from gas appliances.

The final rule was approved by the State Fire Prevention and Building Code Council in late July 2025, after the All‑Electric Buildings Act had been in the works for two years. The council’s approval marks the last step before the law takes effect. The council’s decision followed the earlier federal court ruling that cleared the way for the state to enact the act.

For builders, developers, and property owners, the new requirements mean a shift toward electric heating, cooking, and power systems in all new construction. While the transition may involve upfront costs, the projected long‑term savings on energy bills and construction costs are expected to offset those expenses.

As New York moves to eliminate fossil fuels from most new buildings, the state joins a growing list of jurisdictions seeking to decarbonize the built environment. The law is a significant step toward reducing greenhouse‑gas emissions and improving air quality, while also offering financial benefits to homeowners and businesses through lower utility costs.
