| IECC — International Energy Conservation Code | THE 2024 IECC, published as the 2025 ENERGY CONSERVATION CONSTRUCTION CODE OF NEW YORK STATE (2025 ECCCNYS, publication date July 2025), incorporated by reference into 19 NYCRR PART 1240, EFFECTIVE 2025-12-31. *** DO NOT WRITE "2025 IECC" — THERE IS NO 2025 IECC. "2025" IS THE NEW YORK PUBLICATION LABEL, NOT A MODEL YEAR, AND THIS RUN NEARLY RECORDED IT AS ONE. The Department of State's own Regulatory Impact Statement settles it verbatim: "The proposed rule will amend the Energy Code for residential buildings to a code that includes the 'Residential Provisions' of the 2024 ECCCNYS based upon the most recent (2024) edition of the IECC." NOTE THAT EVEN NEW YORK'S OWN PAPERWORK IS INCONSISTENT — the March 2025 RIS calls the publication the "2024 ECCCNYS" and the July 2025 book calls itself the "2025 ECCCNYS"; the draft posted at dos.ny.gov/system/files/documents/2025/03/2024-ecccnys.pdf still carries the old label. Same document, two names, one 2024 IECC base. New York is on the current model cycle, as with the rest of its 2025 code family — this is NOT an edition-gap state. | 19 NYCRR 1240.1 (State Energy Conservation Construction Code), incorporating the "2025 Energy Conservation Construction Code of New York State" (pub.

| IPC — International Plumbing Code | 2024 IPC — published as the 2025 PLUMBING CODE OF NEW YORK STATE (2025 PCNYS, publication date July 2025), incorporated by reference into 19 NYCRR Part 1222. THE VERBATIM DERIVATION SENTENCE, from the publication preface: "This 2024 edition was developed as a derivative work of the 2024 edition of the International Plumbing Code (IPC)." NOTE THE LABEL TRAP: the book is titled 2025 PCNYS, its own preface calls itself "This 2024 edition", and the Regulatory Impact Statement calls it the "2024 PCNYS" — one publication, three labels, ONE MODEL BASE, THE 2024 IPC. THERE IS NO 2025 IPC. Uniform Code RIS verbatim: the rulemaking would "repeal the current version of the Uniform Code, which is based primarily upon the 2018 editions of eight (8) individual model codes developed and published by the ICC, and adopt new text based primarily upon the 2024 editions of model codes developed and published by the ICC". Scope, 19 NYCRR 1222.2(a) verbatim: "the erection, installation, alteration, repair, relocation, replacement, addition to, use, and maintenance of plumbing systems and nonflammable medical gas, inhalation anesthetic, vacuum piping, nonmedical oxygen, and sanitary and condensate vacuum collection systems, shall comply with the provisions and requirements of the 2025 PCNYS."
