Statewide adopted codes — current (2026)
| Code family | Adopted edition | Notes | Source |
|---|
| Plumbing | New Mexico Plumbing Code = UPC 2021 | NM = UPC | meltplan.com |
| Energy | New Mexico Energy Conservation Code = IECC 2021 | | " |
| Electrical (NEC) | New Mexico Electrical Code = "2020" designation, based on NEC 2021-as-amended ⚠ (naming is unusual — confirm exact base NEC year with the Electrical Bureau) | administered separately by the NM Electrical Bureau | meltplan.com |
| Building | Confirm current IBC base with the state (3-year cycle, but NM sometimes lags behind the ICC release) | | bcapcodes.org |
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.
Major cities / counties
| Jurisdiction | Notes | Building dept. |
|---|
| Albuquerque | Home-rule; own Building Safety Division amendments — confirm current local amendments | cabq.gov |
| Santa Fe | Home-rule; local amendments possible | santafenm.gov |
| Las Cruces | Home-rule; local amendments possible | las-cruces.org |
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.
