Exec. Law § 378 (Uniform Code Standards)

N.Y. Executive Law § 378

Executive Law § 378, within Article 18 (the New York State Uniform Fire Prevention and Building Code Act), enumerates the mandatory subject areas the Uniform Code must address — building construction and materials, fire protection equipment and interior finishes, smoke and carbon monoxide detectors, accessibility (elevators and high-rise emergency planning), flood- and climate-resilient construction in hazard zones, lead and asbestos limits in potable water/pipe systems, and energy efficiency. It is the statutory authority underlying the 19 NYCRR building codes. Subsection (19), the 'All-Electric Buildings' provision, directs the Code to prohibit fossil-fuel equipment and building systems in new buildings not more than seven stories in height (except commercial/industrial buildings over 100,000 sq ft of conditioned floor area) on or after December 31, 2025, extending to all new buildings on or after December 31, 2028. Per a November 12, 2025 stipulation, New York suspended the January 1, 2026 effective date of the implementing regulations pending the Second Circuit's ruling on the federal (EPCA) preemption appeal.
