Do I need a permit for retaining wall construction in Las Vegas?

Permit may be required

It depends. Whether retaining wall construction needs a permit in Las Vegas comes down to the details of your project.

A retaining wall is exempt only if it retains less than 36 inches of unbalanced fill and its total height from top of wall to bottom of footing is 6 feet or less; walls supporting a surcharge load or impounding Class I, II, or III-A liquids are not exempt (14.5.2.9(B)(3) NMAC). Unbalanced backfill height means the difference between exterior finished ground level and the lower of the top of footing or interior finished ground level (14.7.3.10 NMAC). CID's residential guide repeats the retaining wall wording in its list of work needing a New Mexico architect or structural engineer seal, so confirm with the AHJ whether a seal is required. 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).

Local detail for Las Vegas: Las Vegas has no certified local building official, so the New Mexico Construction Industries Division (CID) issues building, electrical, plumbing and mechanical permits and does the inspections. The city issues the zoning clearance you need first. CID's Santa Fe office is listed here; call to confirm it handles your address.
