| IMC — International Mechanical Code | NONE — NEW MEXICO ADOPTS NO EDITION OF THE INTERNATIONAL MECHANICAL CODE AND NEVER MENTIONS IT. NEW MEXICO IS AN IAPMO STATE FOR MECHANICAL, EXACTLY AS IT IS FOR PLUMBING. What governs mechanical work statewide is the 2024 NEW MEXICO MECHANICAL CODE (14.9.2 NMAC), which adopts by reference the 2024 UNIFORM MECHANICAL CODE (UMC, IAPMO) as amended. Adoption verbatim at 14.9.2.8 NMAC: "This rule adopts by reference the 2024 UMC, as amended by this rule." Title provision as amended: the code is styled the "2024 New Mexico Mechanical Code (NMMC)". Searching New Mexico law for an IMC edition returns nothing because there is nothing to return; any national table printing an IMC year for New Mexico is printing a code New Mexico does not use. | 14.9.2 NMAC "2024 NEW MEXICO MECHANICAL CODE", adoption at 14.9.2.8 NMAC ("This rule adopts by reference the 2024 UMC, as amended by this rule."); Construction Industries Division, N.M.

| IPC — International Plumbing Code | NONE — NEW MEXICO ADOPTS NO EDITION OF THE INTERNATIONAL PLUMBING CODE, AND NEVER MENTIONS IT. NEW MEXICO IS AN IAPMO STATE FOR PLUMBING. What governs plumbing statewide is the 2021 New Mexico Plumbing Code, 14.8.2 NMAC, which adopts the 2021 UNIFORM PLUMBING CODE (UPC): 14.8.2.8, verbatim — "ADOPTION OF THE 2021 UNIFORM PLUMBING CODE: A. This rule adopts by reference the 2021 UPC and all appendices, as amended by this rule. B. In this rule, each provision is numbered to correspond with the numbering of the 2021 UPC. C. This rule shall apply in conjunction with the provisions of all applicable New Mexico construction codes, laws and standards." The phrase "International Plumbing Code" appears NOWHERE in 14.8.2 NMAC. Statewide in scope: 14.8.2.6, verbatim — "The purpose of this rule is to establish minimum standards for all plumbing, as defined in CILA Section 60-12-32 NMSA 1978, in New Mexico." The IPC and the UPC are not interchangeable — fixture counts, venting, materials and sizing differ — so any table that shows New Mexico with an IPC edition is wrong about the code that actually governs. | 14.8.2 NMAC, Title 14 Housing and Construction, Chapter 8 Plumbing Codes, Part 2 "2021 NEW MEXICO PLUMBING CODE"; adoption at 14.8.2.8 NMAC; authority NMSA 1978 ss. 60-13-9, 60-13-44, 60-13-45, 60-13-46 and 60-13-47 (14.8.2.3 NMAC); scope tied to "plumbing" as defined at NMSA 1978 s. 60-12-32 (CILA).

| NEC — National Electrical Code (NFPA 70) | 2020 NEC (NFPA 70), as amended by New Mexico. ADOPTING TEXT VERBATIM, 14.10.4.8 NMAC, whose heading is "ADOPTION OF THE 2020 NATIONAL ELECTRICAL CODE": "A. This rule adopts by reference the 2020 National Electrical Code (NEC), as amended by this rule. B. In this rule, each provision is numbered to correspond with the numbering of the 2020 National Electrical Code." The rule is styled the "2020 NEW MEXICO ELECTRICAL CODE" (NMEC) — so New Mexico, as with its plumbing and mechanical codes, ships a STATE-STYLED code over a national base rather than adopting the base bare. NOT the 2023 NEC. CONTRAST WITH NEW MEXICO PLUMBING AND MECHANICAL, WHICH MOVED TO 2024 BASES EFFECTIVE 2026-08-01: ELECTRICAL DID NOT MOVE.
