Nevada to New Mexico: master plumber license reciprocity

New Mexico has no 'master plumber' title. The credential above journeyman is the MM-1 Plumbing contractor classification (install, alter, repair, service and maintain plumbing, fixtures and piping, hot-water heating up to 30 psi or 400,000 BTU/hour, fuel and solar piping, pools, septic and sewer lines, controls at 24 volts or less; natural gas piping requires MM-2), or the MM-98 Mechanical classification that bundles MM-1 through MM-4 and four mechanical specialties. CID issues the contractor's license to the business and a personal, non-transferable certificate of qualification to the qualifying party, the individual who documented four years of experience in the classification within the past ten years and passed the MM-1 trade exam and the Contractor's Business and Law exam, so this site maps the MM-1 qualifying party to the master level. Even with an MM-1 license, hands-on plumbing must be done by or under a certified JP journeyman. CID publishes reciprocity only for EE-98J electrical journeymen; no reciprocity, endorsement or exam waiver is published for plumbing qualifying parties or contractors, although NMSA 60-13-14(C) allows the division to enter into reciprocal agreements with states having equivalent requirements.

Nevada does not issue a master plumber license to individuals, and no county or city was found to issue a master-level plumbing card; Clark County recognizes a 'plumbing qualified individual', which is simply the person who qualifies a contractor's C-1 license with the State Board. The state-level credential is a classification C-1 Plumbing and Heating Contracting license from the Nevada State Contractors Board (NSCB), issued to a sole proprietor, partnership, corporation or LLC and qualified by a named individual rather than held by the plumber personally. An out-of-state master plumber who only wants to work for an employer needs no Nevada license at all (apart from the local journeyman card in Clark County and Reno). To contract, the qualifying individual must show four years of experience as a journeyman, foreman, supervising employee or contractor within the past 15 years (NRS 624.260), pass the PSI-administered Nevada Business and Law exam and the C-1 trade exam within six months of filing (three attempts each), and the business must pay the $300 application fee and $600 biennial license fee, submit a financial statement, fingerprints and background check, and post a bond of $1,000 to $500,000 set by the Board, plus the Residential Recovery Fund assessment ($200 to $1,000) if it does residential work. Under licensure by endorsement (NAC 624.600 and 624.615) the C-1 trade exam and the experience certification are waived for a qualified individual who has held an active license, as the same qualified individual, with no discipline or pending action for the past four years in Arizona (CR-77 Plumbing Including Solar), California (C-36 Plumbing together with C-4 Boiler, Hot Water Heating and Steam Fitting) or Tennessee (CMC Full Mechanical Contractor); a Florida CF Plumbing Contractor gets experience credit but must pass the Nevada C-1 trade exam; the Business and Law exam is never waived. The NSCB equivalency charts contain no Utah chart and no C-1 row for Connecticut, Louisiana, North Carolina, South Carolina, New Mexico, Hawaii, Alabama or West Virginia.
