Plumber License from South Dakota to Iowa: Does It Transfer? (2026)
Does Iowa accept a South Dakota plumbing license?
Yes — Iowa has a reciprocity arrangement covering South Dakota license holders. Apply to the Iowa Plumbing and Mechanical Systems Board (Department of Inspections, Appeals, and Licensing) under its reciprocity/endorsement track; it typically waives the journeyman exam and complete Iowa's remaining requirements.

Verdict
Reciprocity agreement
South Dakota is on Iowa's reciprocity list, which puts this move on the streamlined track — on two conditions. Your South Dakota license must have been earned by examination, not grandfathered in, and be active and in good standing; where it is, Iowa waives its journeyman exam and the requirements below are what it still insists on. Iowa waives its journeyperson plumber exam only for applicants who hold a South Dakota plumbing license obtained on the basis of written examination (its sole reciprocity agreement, approved May 2016); every other out-of-state plumber must pass the Iowa journeyperson exam. One caution: these agreements are directional and revocable. This page's verification date is when we last confirmed South Dakota on Iowa's list; the Iowa Plumbing and Mechanical Systems Board (Department of Inspections, Appeals, and Licensing) link is the live truth.
What's different between South Dakota and Iowa
Computed from both states' verified data rows, in both directions, and from the route every other origin gets into Iowa. Exam notes are our summary of each board's published rules, with sources below.
- Route, each way
South Dakota to Iowa (this page): Reciprocity agreement.
Iowa to South Dakota (the reverse move): Licensure by endorsement.
The two directions differ: South Dakota and Iowa do not give each other's licensees the same route.
- Does coming from South Dakota matter?
Coming from South Dakota matters here: only 1 of 50 origins (the other 49 states and DC) get this result for a move into Iowa.
The others get: licensure by endorsement (40) and no state license to transfer (9).
- Reciprocity agreements
Iowa's reciprocity agreement list names 1 state (South Dakota), including South Dakota.
South Dakota's row names no reciprocity agreement states.
- Application fee
Iowa lists $30–$180 for an out-of-state applicant and South Dakota lists $50 for the reverse move; neither may be the full cost.
- Processing time
Iowa lists up to 2 weeks; South Dakota has no verified processing-time figure on file, so the two cannot be compared here.
- Exam rules on record
Iowa and South Dakota carry different exam notes (our summaries, below); any state law or jurisprudence exam is listed with each state's requirements.
- Iowa (this move): Iowa waives its journeyperson plumber exam only for applicants who hold a South Dakota plumbing license obtained on the basis of written examination (its sole reciprocity agreement, approved May 2016); every other out-of-state plumber must pass the Iowa journeyperson exam
- South Dakota (the reverse move): South Dakota waives its plumber examination for a nonresident who was licensed BY EXAMINATION in another state whose licensure laws are substantially equivalent to South Dakota's and whose plumbing code equals or exceeds the South Dakota plumbing code; the Commission names no fixed partner states and decides comparability case by case, so applicants from non-comparable states, or those licensed by waiver rather than examination, must pass the South Dakota journeyman plumber examination
What changes, South Dakota → Iowa
| South Dakota (current) | Iowa (destination) | |
|---|---|---|
| Application fee | $50 ($50 plumber license application fee (SDPC application, Rev. 02/2026); reciprocity applicants pay the same $50 and file the reciprocity documentation; a $100 exam fee applies only to applicants who must sit the examination; licenses expire December 31 (annual)) | $30–$180 (Journeyperson license fee is $180 for a full three-year period and is prorated down to roughly $30 depending on issue date; +$25 paper-application fee if not filed online. Reciprocity applicants are not charged the $35-per-trade exam-approval fee or the $99 Kirkwood Community College exam fee because the exam is waived.) |
| Processing time | No board-stated processing time; an incomplete application expires 30 days after receipt and all fees are non-refundable | up to 2 weeks (Board indicates it reviews an application/exam-approval submission in up to about two weeks; no reciprocity-specific timeline is published.) |
| Licensing authority | South Dakota Plumbing Commission (Department of Labor and Regulation) | Iowa Plumbing and Mechanical Systems Board (Department of Inspections, Appeals, and Licensing) |
The destination column is what you must satisfy — Iowa sets the rules for this move.
Step by step
- Confirm Iowa's current requirements on the Iowa Plumbing and Mechanical Systems Board (Department of Inspections, Appeals, and Licensing) website (linked below) — rules change.
- Submit the reciprocity application to the Iowa Plumbing and Mechanical Systems Board (Department of Inspections, Appeals, and Licensing) (application linked below).
- Arrange license verification from your current state via the verification system.
- Hold a South Dakota plumbing license issued on the basis of written examination (reciprocity covers only the journeyperson and master licenses, not the contractor license).

- Non-reciprocity applicants must document four years of apprenticeship experience (or a master license from another jurisdiction) and pass the Iowa journeyperson exam.

Frequently asked questions
Can I keep my South Dakota plumbing license after I'm licensed in Iowa?
Yes — plumbing licenses in different jurisdictions run independently. Keep the South Dakota credential active on its own renewal and continuing-education schedule and you hold both, which is common for plumbers working near a state line.
