Who licenses plumbers in South Dakota?
South Dakota uses statewide licensing through the South Dakota Plumbing Commission. The South Dakota Plumbing Commission licenses qualified plumbers and listed specialty installers statewide. (Commission overview) The agency also inspects installations, investigates complaints, and maintains the state plumbing code.
For the main plumbing path, think in four stages: apprentice, third-year apprentice, plumber, and plumbing contractor. The third-year credential is unusually narrow, while the contractor tier carries the longest experience requirement. If you are comparing this route with the usual national pattern, start with how to get a plumbing license.
The license ladder and experience gates
The Commission publishes distinct experience gates for each rung. (licensing requirements)
| Credential | Experience gate | Practical meaning |
|---|---|---|
| Apprentice plumber | Submit the apprentice application and fee | Entry credential while gaining supervised experience |
| Third-year apprentice plumber | Two years as an apprentice at no fewer than 1,900 hours per year | May qualify for the state exam and limited unsupervised work |
| Plumber | Four years as an apprentice at no fewer than 1,900 hours per year | Worker-level license path |
| Plumbing contractor | Six years as a contractor, plumber, or apprentice at no fewer than 1,900 hours per year, including at least two years as a contractor or plumber | Contracting tier |
A plumber applicant needs four years as an apprentice plumber and at least 1,900 hours in each year. A plumbing contractor applicant needs six years in the trade, including at least two years as a plumbing contractor or plumber, at a minimum of 1,900 hours per year.
What experience and exams are required?
Military plumbing experience can earn one year of credit for every two years in the military, up to five years of credit. (licensing requirements) Do not assume that credit removes the application or exam steps.
The Commission administers exams for plumbing contractors, plumbers, and third-year apprentice plumbers. Contractor and plumber exams or re-exams cost $100, while the third-year apprentice exam or re-exam costs $50. First-time examinees must submit the application and exam fees and receive approval before scheduling. (exam page)
Treat the published experience threshold as the minimum file you must prove, not merely time that has passed on a calendar.
How to apply without losing your experience record
Use this order:
- Choose the correct credential and application.
- Collect experience verification from the licensed contractor who supervised the work.
- Submit the application and required fee.
- Wait for Commission approval and instructions on the remaining fees or exam.
- Schedule and pass the exam when the credential requires one.
- Pay the remaining license fee and keep the issued credential current.
Applicants seeking a license by exam must provide experience verification signed by a licensed plumbing or specialty contractor, or an out-of-state equivalent, who supervised their work. Applicants cannot verify their own experience. (applications and forms)
Pierre exams are available by advance appointment. Sioux Falls and Rapid City sessions are held when the Commission has enough applicants to justify travel. (exam page)
The third-year privilege and specialty scopes
The third-year apprentice privilege is limited. After two years and 3,800 hours, an apprentice who passes the state exam may work without supervision during the third and fourth apprentice years only on single-family dwellings. (licensing requirements) It is not a general plumber or contractor credential.
The Commission also licenses work involving sewer and water, appliances, manufactured and mobile homes, underground irrigation, water conditioning, and individual or small on-site wastewater systems. (Commission overview) Those categories have their own forms and experience rules. A firm adding one of those scopes should classify it before bidding and include licensing in its construction-business startup checklist.
Exam costs, annual renewal, and continuing education
South Dakota plumbing licenses expire annually on Dec. 31. (Commission overview) An expired license requires reinstatement rather than ordinary renewal.
Plumbing contractors, restricted plumbing contractors, plumbers, restricted plumbers, and third-year apprentice plumbers must complete at least four hours of plumbing-related continuing education during the prior calendar year. Two of the four hours must cover code, and completion must reach the Commission before renewal. (continuing-education requirements)
Exam costs are separate from application and license fees: $100 for contractor exams and re-exams, $100 for plumber or installer exams and re-exams, and $50 for third-year apprentice exams and re-exams. (exam page) Use a contractor license cost budget that separates application, exam, license, education, and reinstatement expenses.
Does South Dakota offer reciprocity?
Reciprocity is possible, but it is not automatic. The Commission may license a nonresident without examination when the other state’s plumber requirements are substantially equivalent to South Dakota’s. (reciprocity page)
The applicant must have been licensed by examination, come from a state with similar licensing laws, and have worked under a plumbing code equal to or stricter than South Dakota’s. The Commission may investigate and require affidavits. If the prior license came from testing on the IPC or another code, the applicant must provide current-license verification and the experience used to obtain it before being approved for the corresponding South Dakota exam.
The useful takeaway: send the Commission your exact license history and experience record before assuming another state’s credential will waive the exam.
