Nevada to Iowa: master plumber license reciprocity

Iowa's highest person-held plumbing credential is the statewide Master Plumber license issued by the Plumbing and Mechanical Systems Board (DIAL); a master plans and superintends plumbing work, may perform all journeyperson duties, and serves as master of record for a licensed contractor (one contractor per discipline at a time without board approval). A new applicant must be 18, disclose criminal convictions, and pass the Iowa master plumbing exam; to sit for it the applicant must hold either a master plumbing license in another jurisdiction or a journeyperson license with two years of journey-level experience. The exam is approved by the board ($35 application) and administered by Kirkwood Community College ($95 per attempt as listed on the master page, 75% to pass). Iowa's only reciprocity agreement is with South Dakota for plumbers licensed by written exam; masters from all other states are admitted directly to the Iowa master exam on the strength of their license. The separate Contractor license ($250 plus $150 registration per three-year term, with $500,000 liability insurance and a $5,000 bond) is required to contract for plumbing work as a business. Licenses run three years (current period ends June 30, 2029) with a full-term fee of $240 and eight hours of continuing education per term.

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.
