Do I need a permit for plumbing fixture or repiping in Las Cruces?

Permit required

Yes. In New Mexico, plumbing fixture or repiping generally requires a permit, and Las Cruces is no exception.

Re-piping is plumbing alteration or replacement work; only minor repairs and replacement of faucets, taps, or jets are exempt from permits (NMSA 60-13-45(B)(1)). A homeowner who does their own plumbing must submit an isometric drawing for review (CID FAQ) and obtain a homeowner plumbing permit for the primary residence (14.5.2.18 NMAC). The New Mexico Plumbing Code governs; the 2024 edition is effective August 1, 2026 and mandatory for permits from January 1, 2027 (CID codes page). Which office issues the permit depends on the address: a city or county with its own certified building department, or CID in all other areas (14.5.1.7 NMAC; NMSA 60-13-41).
