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.

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 | ~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.
