By Council Member Sanchez (by request of the Mayor)

A Local Law to amend the administrative code of the city of New York, in relation to conforming the New York city energy conservation code to the New York state energy code with amendments unique to construction in the city, and to repeal section 28-1001.2 of such administrative code relating to such conforming amendments

Be it enacted by the Council as follows:

Section 1. Statement of findings and purpose. The New York State Energy Conservation Construction Code (the “New York State Energy Code”) is promulgated by the State Fire Prevention and Building Code Council pursuant to Article 11 of the New York State Energy Law. In accordance with Article 11, the New York City Energy Conservation Code is stricter than the New York State Energy Code. The purpose of this local law is to conform the New York City Energy Conservation Code to recent changes in the New York State Energy Code with local law amendments unique to construction in the city.

[Consolidated provisions are not included in this Appendix A]

§ 4. This local law shall take effect on the same date that the New York State Energy Conservation Construction Code, as adopted on October 1, 2025, by the State Fire Prevention and Building Code Council pursuant to Article 11 of the New York State Energy Law takes effect, except that if this local law becomes law after such date, it is retroactive to and deemed to have been in effect as of the effective date of such New York State Energy Conservation Construction Code.*

§ 5. If the Department of Buildings determines that compliance software described in section 101.5.1 of the New York City Energy Conservation Code, as added by section three of this local law, is not publicly available on the effective date of this local law, and that compliance with provisions of the New York City Energy Conservation Code as enacted pursuant to this local law is not practicable until such software is available, such Department shall follow any applicable direction or published guidance of the State Fire Prevention and Building Code Council regarding compliance with such code or the New York State Energy Code, as defined in section 28-1001.1.1 of the Administrative Code of the City of New York, as amended by section two of this local law, by municipalities that enforce such code, similarly circumstanced by the unavailability of such compliance software. In the absence of such direction, however, the department may provide notification on its website and continue to enforce provisions of the version of the New York City Energy Conservation Code that was in effect immediately prior to the effective date of this local law, until such time as the Department determines such software is publicly available, or as soon as practicable thereafter, and rescinds such notification. In the event of such notification, compliance with provisions of law in effect prior to the effective date of this local law pursuant to this section shall be deemed for all purposes to be compliance with the New York City Energy Conservation Code as enacted pursuant to this local law. The Department shall make all reasonable efforts to inform the interested parties of any such notification and subsequent recission. The Department shall also inform the Corporation Counsel of the publication and subsequent recission of such notification, and the Corporation Counsel shall provide the same to the New York State Legislative Bill Drafting Commission and the publishers of Administrative Code of the City of New York. Failure to provide such notifications shall not affect the effective date of any section of this local law or the validity of actions taken by the Department or Corporation Counsel pursuant to this section.
