Moving to South Dakota as a master plumber: every state's rule

South Dakota has no 'master plumber' license. The top individual tier is the statewide Plumbing Contractor license issued by the State Plumbing Commission - a person 'qualified and skilled in the planning, superintending, and the practical installation of plumbing, and otherwise qualified and registered to contract for plumbing installations and conduct the business of plumbing' (SDCL 36-25-1(6)) - which this site maps to the master level. A new applicant needs six years' experience as a plumbing contractor, plumber or apprentice at not less than 1,900 hours per year, with at least two of those years as a plumbing contractor or plumber, then passes the Commission-administered three-part exam on the South Dakota plumbing code (2024 Uniform Plumbing Code with state amendments) at 80%; the code may be used on the sizing-drawing part of the contractor exam. Fees are a $50 application fee, a $100 exam fee and a $275 license fee; licenses expire December 31 and renew annually for $275 with four hours of continuing education each calendar year. Out-of-state master plumbers or plumbing contractors licensed by examination in a state with similar laws and a UPC-equivalent code may be licensed without examination under SDCL 36-25-21; others are approved for the contractor exam on proof of equivalent experience.
