How New Mexico plumbing licensing works
A New Mexico plumbing company needs a contractor license issued to the business entity and a certified qualifying party for the work it contracts. Individual field credentials are separate: journeymen need the appropriate certificate, while apprentices may perform plumbing work under direct journeyman supervision.
The Construction Industries Division says it licenses contractors and requires licensure for anyone practicing or offering to practice construction contracting. CID’s application page says it issues licenses to qualified business entities that employ or are owned by one or more qualifying parties certified for the scope the business intends to perform.
For a first-pass comparison of this structure with other states, use our plumbing license guide. The sections below stay focused on New Mexico’s current MM-1, JP/JPG, apprentice-supervision, qualifying-party, bond, and renewal rules.
MM-1 plumbing scope and the natural-gas split
The official classification rule identifies MM-1 Plumbing as a residential and commercial license requiring four years of experience. Its scope includes plumbing fixtures and piping, excavation and backfill, qualifying hot-water heating systems, fuel-oil and gasoline piping, solar-thermal piping, potable-water irrigation sprinklers, pools and spas, low-voltage controls, septic tanks, manholes, and sewer lines.
The MM-1 rule states that MM-1 does not include natural-gas appliances or natural-gas piping. New Mexico places natural-gas fitting in MM-2, also with a four-year experience requirement. MM-98 Mechanical indicates authority in MM-1 through MM-4 and specified mechanical specialties.
That split is the practical trap. If your jobs include both plumbing and natural-gas work, MM-1 alone does not cover the full sold scope. Map each recurring line item to the rule before selecting the business classification or the qualifying party’s exam path.
JP and JPG journeyman certificates
New Mexico’s plumbing worker certificates include JP Journeyman Plumber and JPG Journeyman Plumber and Natural Gas Fitter. NMAC 14.6.4 says mechanical-plumbing journeyman classifications require two years of experience unless otherwise specified. The same rule says JPG may work under MM-1, MM-2, or MM-98.
Two published rules disagree about JP employment scope. The journeyman-certification rule says JP may work under MM-1, MS-3, MS-6, or MM-98. But the separately published classification-and-scope rule says JP may work only under MM-1 or MM-98. Because both provisions remain published, do not rely on JP authority under MS-3 or MS-6 without obtaining a CID scope determination for the planned work.
Journeyman certification is not the only lawful field path. NMAC 14.6.4 expressly allows an apprentice to perform mechanical or plumbing work under the direct supervision of a validly certified journeyman employed by a validly licensed person or valid annual-permit holder. The classification-and-scope rule permits no more than two unregistered apprentices per supervising journeyman on commercial or industrial work. The same rule permits no more than three unregistered apprentices per supervising journeyman on residential work.
For renewal, NMAC 14.6.4 requires affected plumbing journeymen to complete at least 16 hours of approved coursework before renewal or reinstatement. The same rule requires at least eight hours to cover the current CID code enforced for the classification.
Qualifying-party experience and business continuity
A plumbing contractor’s qualifying party must match the classification. CID’s licensing rule requires qualifying-party applicants to document four years of satisfactory work experience within the 10 years immediately before applying. The same rule says a passing exam score is 75 percent or higher.
The licensing rule allows accredited technical training to replace part of the field record, but each year of equivalent training counts as one-half year of experience and training cannot exceed half of the total experience requirement.
The risk is operational, not theoretical. The rule says that when a license loses its qualifying party, it is automatically cancelled and the licensee may not bid or begin new work in that classification. Existing work may continue for no more than 120 days before affected permits are cancelled.
Application process
Use this order:
- Match sold work to MM-1, MM-2, MM-98, or another exact classification.
- Choose the qualifying party and assemble affidavits covering the required experience.
- Submit the qualifying-party application and work-experience affidavit to PSI.
- After preapproval, pass the classification exam and the Contractor’s Business and Law requirement.
- Submit the company application with its documented enclosures: the bond, tax registration, applicable entity records, qualifying-party proof, and fees. Treat workers’ compensation as a separate coverage obligation for every licensed entity rather than claiming it is an application enclosure.
- Staff field work with the appropriate JP or JPG certificate holders, or apprentices working within the direct-supervision rules and applicable ratios.
- Obtain the permits and inspections required for the specific work and jurisdiction.
CID lists a $36 qualifying-party application fee and requires notarized applicant and affiant signatures. Complete submissions go to PSI’s Albuquerque office by hand or mail; faxed or emailed forms are not accepted.
After the qualifying party passes, CID says the company application must include a $36 application fee plus applicable license fees, a license bond, tax registration, applicable entity certificates, and qualifying-party certificate or test scores. CID’s application page says workers’ compensation coverage is required for all licensed entities.
Verified costs, bond, and renewal workload
The fixed amounts verified on CID’s current application materials are limited but useful:
| Item | Verified amount or rule |
|---|---|
| Qualifying-party application | $36 |
| Company license application | $36 plus applicable license fees |
| Contractor license bond | $10,000 |
| Workers’ compensation | Coverage required for every licensed entity |
| Exam registration | Check the charge in the applicable PSI Candidate Information Bulletin |
| Journeyman renewal education | 16 approved hours, including at least 8 code hours |
New Mexico’s licensing rule requires a $10,000 bond at initial licensure and as a condition of renewal. The bond must cover the full initial-license or renewal period. CID’s application page says workers’ compensation coverage is required for all licensed entities. NMAC 14.6.3 lists failure to comply with workers’ compensation laws as an event that may make a license or certificate invalid. Keep both the bond and required workers’ compensation in the renewal checklist.
The fetched official material did not establish a fixed ordinary application, preapproval, exam-scheduling, or issuance interval, and it did not expose a reliable current MM-1 class fee or exam charge. CID says applicants must be preapproved to schedule exams; after CID or PSI accepts the affidavit and work experience, an approval notice is sent and the applicant may schedule with PSI. The verified sequence is qualifying-party filing, experience review, exam approval and scheduling, passing scores, then the company application and issuance requirements. Check the applicable PSI Candidate Information Bulletin before budgeting classification and exam charges.
The bond’s face amount is not the premium paid to a surety. Add the actual license-class fee, PSI exam charges, bond premium, workers’ compensation, tax registration, continuing education, and permit costs to the project budget.

Plumbing reciprocity: do not assume a transfer
Do not plan on plumbing-journeyman reciprocity. CID’s current license application page says the only journeyman classification reciprocated in New Mexico is EE-98J, the electrical classification. That means JP and JPG applicants should use the normal New Mexico certification route unless CID publishes a later rule or program that specifically changes plumbing eligibility.
Qualifying-party exam waivers are also narrower than a generic “reciprocity” promise. The fetched licensing rule identifies a waiver route for specified NASCLA general-construction or electrical exams, not a blanket MM-1 plumbing transfer.
Bottom line: bring out-of-state records as evidence, but build the schedule around New Mexico classification review, documented experience, and New Mexico testing rather than assuming a plumbing credential transfers.
