Adoption model & precedence

  • State sets the floor; home-rule municipalities and some counties (Albuquerque, Santa Fe, Las Cruces) can and do adopt local amendments — always more stringent, never less (the more restrictive requirement governs on conflict).
  • AHJ = local building department — confirm local amendments directly, especially in Albuquerque.

AHJ fallback (when local adoption is unverified)

  • State baseline (certain): UPC 2021 (plumbing), IECC 2021 (energy); electrical edition flagged for direct Electrical Bureau confirmation.
  • Action: always check Albuquerque/Santa Fe/Las Cruces for local amendments layered on the state floor — home-rule municipalities are active in NM.
