Codes adopted

New Mexico is a statewide-minimum-code state under the Construction Industries Licensing Act (NMSA 1978 § 60-13-44(E)): 'All political subdivisions of the state are subject to the provisions of codes adopted and approved under the Construction Industries Licensing Act. Such codes constitute a minimum requirement for the codes of political subdivisions.' A county or municipality may become its own code-enforcement authority (operate independently of the state Construction Industries Division field office model) if it employs a certified building official and has adopted at least the current state minimum code standards (NMSA 1978 § 60-13-41(D)-(F)). GOVERNANCE MODEL CONFIRMED: unlike some New Mexico counties that route permits through the state CID field office, Doña Ana County SELF-ADMINISTERS for all trades — Building, Electrical, Plumbing, and Mechanical alike — through its own Community Development Department / Building Services Division, headed by Sean Vick, the Doña Ana County Certified Building Official/Assistant Director (per the department's own 'Welcome to Building Services' page). The division also employs its own Certified Building Inspector (Jesse Gomez), Certified Electrical Inspectors (Riley Roman, Joel Candelaria), and Certified Plumbing/Mechanical Inspectors (Candido Jasso and David Murillo) — confirming direct county-level review and inspection for every trade, not CID field-office enforcement.2021 International Building Code (IBC) — per the Doña Ana County Building Services 'Building Codes' page (donaana.gov)2021 International Residential Code (IRC) — per the Doña Ana County Building Services 'Building Codes' page2021 International Energy Conservation Code (IECC) — per the Doña Ana County Building Services 'Building Codes' page; the county's own Single Family Dwelling Permit Application requires a signed '2021 RESCheck' Energy Certificate, confirming the 2021 IECC edition is the one actually enforced in practice2021 Uniform Mechanical Code (IAPMO) — per the Doña Ana County Building Services 'Building Codes' page2021 Uniform Plumbing Code (IAPMO) — per the Doña Ana County Building Services 'Building Codes' page2021 International Existing Building Code (IEBC) — per the Doña Ana County Building Services 'Building Codes' page2017 ICC/ANSI A117.1 (Accessible and Usable Buildings and Facilities) — per the Doña Ana County Building Services 'Building Codes' page2020 National Electrical Code (NEC) — per the Doña Ana County Building Services 'Building Codes' page (this matches the current 14.10.4 NMAC statewide adoption also enforced in the City of Las Cruces; NOTE: the county's own Reroof & Reroof/Overlay Permit Requirements handout still lists an older code slate — '2015 IRC; 2015 NMRBC; 2009 Energy Conservation Code; 2015 Uniform Plumbing Code; 2015 New Mexico Plumbing Code; 2012 Swimming Pool, Spa, Hot Tub Code; 2015 Uniform Mechanical Code; 2015 New Mexico Mechanical Code; 2012 New Mexico Solar Energy Code; 2017 NEC; 2017 New Mexico Electrical Code' — this appears to be a stale, unrevised handout PDF; the county's live, currently-published Building Codes page (2021 IBC/IRC/IECC/UMC/UPC family, 2020 NEC) is treated as the authoritative current adoption for this entry)2021 International Fire Code (IFC) — per the Doña Ana County Building Services 'Building Codes' page2012 Uniform Swimming Pool, Spa and Hot Tub Code — per the Doña Ana County Building Services 'Building Codes' pageDoña Ana County makes clear it cannot host these copyrighted code texts online and directs the public to review physical copies in person at the Building Services Dept., 845 N. Motel Blvd., Las Cruces, NM, or to consult the New Mexico Regulation and Licensing Department (RLD) Construction Industries Division's own current-adoption page for the statewide baseline (rld.nm.gov/construction-industries/rules-laws-and-building-codes).
