Building permits in Las Vegas

Most construction, renovation, and repair work in Las Vegas, San Miguel County needs a building permit from Construction Industries Division (CID), Santa Fe Field Office, NM Regulation and Licensing Department. Below are the office's contact details and online portal, plus step-by-step guides for the projects homeowners ask about most, from roofing and solar to fences, sheds, pools, and HVAC.

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.

Las Vegas is covered by New Mexico's statewide construction codes, which for homes means the 2021 New Mexico Residential Building Code (an amended 2021 IRC) with the state energy, electrical, plumbing, and mechanical codes. Under 14.5.2.8 NMAC, erecting, altering, repairing, improving, converting, or demolishing a building, and doing electrical, plumbing, or mechanical work, requires a permit from the authority having jurisdiction, and every re-roof needs a building permit. The authority having jurisdiction is a city or county with its own full-service building department and certified building official, such as Albuquerque, Rio Rancho, Santa Fe, Las Cruces, Bernalillo County, or Dona Ana County; everywhere else it is the state Construction Industries Division, which issues permits and inspects through its Albuquerque, Santa Fe, and Las Cruces offices. The statewide exemptions are narrow (for example a one-story detached accessory building of 120 square feet or less) and there is no dollar-value exemption, so confirm with the office that has jurisdiction over the address in Las Vegas.

Permit FAQs for Las Vegas

Do I need a building permit in Las Vegas?
Most construction, renovation, and repair work in Las Vegas needs a permit, including structural changes, electrical, plumbing, mechanical, roofing, and pools. Small cosmetic work is sometimes exempt. Every project must still meet the 2021 New Mexico Residential Building Code (14.7.3 NMAC, a state-amended 2021 International Residential Code, effective July 14, 2023 and amended January 13, 2025), with the 2021 New Mexico Residential Energy Conservation Code (14.7.6 NMAC), the 2020 New Mexico Electrical Code (14.10.4 NMAC), and the New Mexico plumbing and mechanical codes, even when a permit is not required.

Who issues building permits in Las Vegas?
Construction Industries Division (CID), Santa Fe Field Office, NM Regulation and Licensing Department issues permits for property inside Las Vegas, San Miguel County. Your mailing city is not always the authority that permits your property, so confirm the jurisdiction before you apply. This page lists the department's phone, address, website, and online portal.
Can I pull my own permit as a homeowner in Las Vegas?
In Las Vegas, a person may build or alter their own single-family home without a contractor license (NMSA 60-13-3(10) and (11)) and may get a homeowner permit for their primary residence (14.5.2.18 NMAC). The homeowner must personally do the major portion of the work by dollar value, the permit covers only the owner's primary residence and appurtenant structures, and electrical and plumbing homeowner permits require passing a CID exam; the exemption never waives permits, inspections, or codes.
Is there a dollar amount under which no permit is needed in Las Vegas?
Not statewide. New Mexico sets no statewide dollar threshold that waives a building permit, so whether small or cosmetic work needs a permit is decided locally. Confirm the exempt-work list and any value threshold with Construction Industries Division (CID), Santa Fe Field Office, NM Regulation and Licensing Department before you start.
How much does a permit cost and how long does it take in Las Vegas?
Fees and review times are set locally and change often, so confirm the current numbers with Construction Industries Division (CID), Santa Fe Field Office, NM Regulation and Licensing Department or its online portal. Fees are usually based on the value of the work or a fixed schedule, and simple residential permits are frequently reviewed faster than new construction.
