In May 2023, the state of New York became the first state to ban "fossil-fuel equipment" in some new buildings starting in 2026 and others in 2029 (USA Today, CNN, NY State Assembly - A03006C, see "Part RR"). The date the bans would take effect would be immaterial, and bans with limited exceptions (e.g., for buildings without access to an electrical grid) would count. Bans imposed by political subdivisions of states (e.g., cities, counties) would be immaterial (Building Decarbonization Coalition). A ban would have to include single and multifamily occupancy buildings, and if a state imposed then repealed a ban as of 1 January 2024, the repealed ban would not count (Tech 24 Construction).
