Indiana to South Dakota: journeyman plumber license reciprocity
South Dakota has no reciprocity agreement with Indiana. A Indiana journeyman plumber applies by endorsement.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
License by reciprocity for any state with substantially equivalent regulation (SDCL 36-25-21; ARSD 20:53:02:21)
The board reviews your out-of-state credentials case by case. Some exam is usually still required, often only a law or code exam.
South Dakota has a single, all-states rule rather than a list of partners. Under SDCL 36-25-21 the Commission 'may register, without examination upon the payment of the required initial application fee, examination fee, and license fee, a nonresident applicant who is registered in another state' whose regulation of plumbers it 'determines ... is substantially equivalent'. ARSD 20:53:02:21 sets the test: the applicant 'shall have been licensed by examination in the state from which he comes, the state shall have licensure laws similar to South Dakota's', and the origin state's plumbing code 'shall be equal to or exceed the South Dakota state plumbing code' (the 2024 Uniform Plumbing Code); the Commission investigates and may require affidavits, and 'the normal examination fee shall accompany the application'. The Plumbing License Application's 'License by reciprocity' box requires proof of license by exam, a license verification from the origin board and proof of four hours of continuing education. The Commission's page warns that anyone who 'received your license by testing on the IPC or another code' is instead approved to take South Dakota's plumber exam on verification of the current license and the experience behind it, and applicants from jurisdictions that did not require a license must submit work-experience verification and proof that licensure was not required (ARSD 20:53:03:03). On approval the applicant pays the $105 license fee (a $50 temporary license valid three months is available while an application is pending).
examTradeRequired is false only when the Commission finds the origin state substantially equivalent - in practice a state that licenses plumbers by examination on the Uniform Plumbing Code. Applicants tested on the International Plumbing Code (the majority of states) fall to the ExperienceCredit route in ARSD 20:53:03:03 and 20:53:02:21's IPC caveat: same $50 application and $100 exam fee, three-part Commission exam at 70%, with out-of-state hours counted toward the four-year/1,900-hours-per-year requirement via the Plumbing Experience Verification Form signed by the supervising contractor 'or equivalent if from another state'. The Commission publishes no list of states it deems equivalent and no processing time. A city-issued origin license is not a license 'by examination in the state', so it does not qualify for the no-exam route, although the underlying hours can be credited. ARSD 20:53:02:21 (as amended July 2, 2025) and SDCL 36-25-21 (as amended 2025) both require the exam fee to be paid even when the exam is waived; the Commission's web page still quotes the older statute wording. The application form says an application expires 30 days from receipt if incomplete; exam approvals lapse after six months (ARSD 20:53:02:18). Whether SD requires the four CE hours to have been completed in the prior calendar year is not specified on the form.

Statewide license
Issued by South Dakota State Plumbing Commission (Department of Labor and Regulation)
South Dakota issues a statewide Plumber license through the State Plumbing Commission under SDCL chapter 36-25 and ARSD article 20:53; it has no 'journeyman' title, but the Plumber license is the journeyman-level credential (a person working under the direction of a plumbing contractor, SDCL 36-25-1(3)). A new applicant needs four years as an apprentice plumber at not less than 1,900 hours per year (7,600 hours), or three years and 5,700 hours with an accredited 9-month/1,020-hour trade-school program or 3-year association apprenticeship; military plumbing earns one year of credit per two years served (max five). The Commission itself administers a three-part exam on the South Dakota plumbing code (2024 Uniform Plumbing Code with state amendments) - open-book code questions, closed-book code questions and stack/waste/vent sizing drawings - passed at 70%, offered by appointment in Pierre and periodically in Sioux Falls and Rapid City; a retake is allowed once every three months. Fees are a $50 application fee, a $100 exam fee and a $105 license fee; licenses expire December 31 and renew annually for $105 with four hours of continuing education each calendar year. Out-of-state plumbers licensed by examination in a state with similar laws and a plumbing code equal to or exceeding South Dakota's may be licensed without examination under SDCL 36-25-21; those tested on the IPC or another code, or from non-licensing jurisdictions, are approved for the South Dakota exam on proof of equivalent experience.
