Getting a plumbing license in New Mexico is a process managed by the state's Regulation and Licensing Department (RLD), Construction Industries Division (CID). The CID has established clear pathways for tradespeople to become certified as a Journeyman Plumber (JP) or licensed as an MM-1 Plumbing contractor, ensuring all work meets state safety and code standards. This guide details the specific requirements for each classification, from experience and exams to fees and renewal.
Do You Need a Plumbing License in New Mexico?
Yes, most plumbing work in New Mexico requires a license or certificate issued by the New Mexico Regulation and Licensing Department (RLD), Construction Industries Division (CID). State-level licensing ensures that individuals and companies performing plumbing work are qualified, knowledgeable of the state-adopted plumbing code, and accountable for public health and safety. While some minor work on one's own property may be exempt, any plumbing that requires a permit or is performed for compensation necessitates proper licensure.
New Mexico Plumbing License Classifications & Scopes
New Mexico offers specific plumbing license classifications through the Construction Industries Division (CID), including the Journeyman Plumber (JP) Certificate of Competence and various contractor licenses such as MM-1 Plumbing and the broader MM-98 General Mechanical. Each classification authorizes a different scope of work and has distinct experience requirements as defined in 14.6.6 NMAC.
- Journeyman Plumber (JP) Certificate of Competence: This certificate allows an individual to perform plumbing work under the supervision of a licensed MM-1 or MM-98 contractor. Applicants need two years of practical experience to qualify.
- MM-1 Plumbing (Contractor License): This license authorizes a contractor to bid on, contract for, and perform all plumbing work. A qualifying party for an MM-1 license needs four years of experience.
- MS-3 Septic Tanks & Sewer (Contractor Sub-classification): This classification is for work specific to septic tanks, sewer lines, and similar systems. It requires two years of experience and can be held on its own or added to an MM-1 or other mechanical license.
- MM-98 General Mechanical (Contractor License): This is a broad umbrella classification that covers plumbing (MM-1), pipe fitting, HVAC, and other mechanical trades.
- GB-98 General Building Contractor: Per 14.6.6 NMAC, a licensed GB-98 contractor is permitted to bid and act as the prime contractor on a project that includes plumbing, provided the major portion of the work falls under the GB-98 classification scope.

New Mexico Plumbing License Exam Details
Under 14.6.3 NMAC, examinations are administered by the Construction Industries Division (CID) "or its designee." CID's current testing and licensing-paperwork designee is PSI, which delivers the New Mexico plumbing examinations on CID's behalf, assessing both trade knowledge and, for contractors, business and law principles.
- Exam Content: The trade exam covers topics based on the New Mexico Plumbing Code, which adopts the Uniform Plumbing Code (IAPMO) with state-specific amendments. Questions will test your knowledge of drainage, waste, vents, water distribution, fixtures, and safety. The Business and Law exam covers topics like labor law, tax regulations, lien laws, and project management.
- Exam Format: Exams are computer-based and administered at official PSI testing centers.
- Scheduling and Locations: You can schedule your exam directly with PSI after receiving approval from the CID. For current scheduling information and a list of testing sites, refer to the exam scheduling page linked on the NM RLD CID website.
- Preparation Resources: The CID and PSI provide candidate information bulletins that outline the topics covered on each exam and list approved reference materials. It is highly recommended to study the New Mexico Plumbing Code (14.5.2 NMAC) and other referenced materials.

New Mexico Plumbing License Renewal & Continuing Education

Contractor License Renewal (MM-1, MS-3, etc.)
Per 14.6.3.8.E NMAC, contractor licenses are valid for a three-year period. To renew, contractors must submit the renewal application, pay the required fees ($50.00 per year), and provide proof of a current $10,000 contractor license bond.

Journeyman certificates also require renewal. Critically, per 14.6.4.8.H NMAC, journeymen must complete 16 hours of approved continuing education (CE) coursework prior to renewal.
- At least 8 of the 16 hours must cover the current plumbing code adopted and enforced by the CID.
- Course providers must be approved by the CID and are required to report your completion.
Reciprocity and Endorsement for New Mexico Plumbing Licenses
New Mexico does not have a broad reciprocity agreement for the MM-1 plumbing contractor classification, requiring most out-of-state applicants to go through the standard application and examination process. While the state's rules allow for licensing by credentials or endorsement in some cases, it is not a common pathway for this trade. Applicants with a license from another state should contact the NM CID directly to inquire about any potential for an endorsement path based on their specific qualifications and license history.
How to Verify a New Mexico Plumbing License
The New Mexico Regulation & Licensing Department provides an online portal to look up and verify the status of any contractor or journeyman license. You can use this service to check if a plumber's license is active, view their classifications, and see the license expiration date. This is an essential step for consumers hiring a professional and for contractors verifying the status of their subcontractors.
Penalties for Unlicensed Plumbing Work in New Mexico
Performing plumbing work without the required New Mexico license or certificate is a violation of state law. The Construction Industries Division is authorized to issue citations, assess monetary penalties, and take legal action against unlicensed individuals or companies. Unlicensed work can also void property insurance claims and create significant liability for property owners.
