Nevada to Oklahoma: master plumber license reciprocity

Oklahoma has no 'master plumber' title; its highest person-held plumbing credential is the Plumbing Contractor license, which CIB describes as 'the highest ranking plumbing license' and issues to an individual who passes the two-part contractor exam (technical trade and Plumbing Business and Law, 75% on each part, PSI, $92 per portion). This site maps the Unlimited Plumbing Contractor license to the master level. An applicant needs the journeyman qualifications plus one additional year, so four years (about 8,000 hours) of verifiable plumbing experience, and pays $330 ($30 application plus $300 initial license). After passing, the license is inactive until the contractor files a $5,000 corporate surety bond (or $5,000 cash or certificate of deposit) and a $50,000 commercial general liability certificate with CIB; only a licensed contractor may contract for plumbing work, and the licensee may operate as an individual, firm, LLC or corporation. CIB's Arkansas agreement covers journeymen only, so no state has contractor reciprocity with Oklahoma; out-of-state masters and contractors use exam equivalency where available or sit the full exam. Licenses renew annually ($200) with six hours of continuing education every 36 months.

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.
