All-Electric Building Mandate (AEBA)
The All-Electric Building Act is an electrification mandate that applies to most new residential buildings up to seven stories and prohibits the use of fossil fuel–burning equipment, including gas stoves, fireplaces, and propane systems. The mandate was originally scheduled to take effect on December 31, 2025.
Enforcement has since been formally delayed by New York State as a result of ongoing litigation and extensive advocacy led by the New York State Builders Association and its plaintiff partners. The State has agreed to pause implementation until a mid-level federal appellate court issues a ruling, with the delay extending further if the case proceeds to the U.S. Supreme Court.
LIBI’s Position
LIBI supports a pause in implementation so the State can assess electric grid readiness and understand the real cost impacts on housing before moving forward. Based on warnings from NYISO, LIBI believes grid reliability, particularly on Long Island, must be addressed first. A delay allows time to strengthen transmission, add reliable zero-emission generation and storage, and align energy policy with the urgent need to keep housing production affordable and moving.
LIBI opposes moving forward with the mandate before the grid is prepared and without a clear plan to address housing impacts. Premature implementation risks higher construction costs, project delays, and reliability issues during peak demand, all of which ultimately fall on homebuyers, renters, and local governments.
