Plumber License from New York to Iowa: Does It Transfer? (2026)
Does Iowa accept a New York plumbing license?
There is no New York state license to carry to Iowa: New York issues no statewide journeyman plumber license. Iowa does license this work, so ask the Iowa Plumbing and Mechanical Systems Board (Department of Inspections, Appeals, and Licensing) whether it credits a local license or your documented experience; otherwise you qualify as a new applicant.

Verdict
No state license to transfer
The issue on this move is the starting point: New York issues no statewide journeyman plumber license — plumbing there is regulated at the contractor level or by cities and counties — so there is no New York state license for Iowa to verify or endorse. Iowa does license plumbers, through the Iowa Plumbing and Mechanical Systems Board (Department of Inspections, Appeals, and Licensing), and it reviews out-of-state plumbers for endorsement, but that route starts from a state license. Ask the board, in writing, whether it credits a local New York license, a contractor-level credential or your documented hours; otherwise plan to qualify as a new journeyman applicant. 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.
What's different between New York 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
New York to Iowa (this page): No state license to transfer.
Iowa to New York (the reverse move): No state license to transfer.
New York issues no statewide journeyman plumber license, so neither direction is a state-license transfer.
- Does coming from New York matter?
Coming from New York matters here: only 9 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 reciprocity agreement (1).
- Reciprocity agreements
Iowa's reciprocity agreement list names 1 state (South Dakota), not including New York.
- Fee and processing
New York issues no statewide journeyman plumber license, so there is no New York state license application fee or processing time to compare with Iowa's.
- Exam rules on record
Iowa and New York 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
- New York (the reverse move): Not applicable at the state level — New York issues no statewide plumber license, so there is no state journeyman exam to waive or transfer. Each municipality (e.g., New York City) sets and administers its own plumber licensing and exams and generally does not recognize licenses issued by other jurisdictions.
What changes, New York → Iowa
| New York (current) | Iowa (destination) | |
|---|---|---|
| Application fee | Set locally and varies by municipality; e.g., New York City charges a $585 Master Plumber written-exam fee and a separate $530 practical-exam fee (both paid through DOB NOW; the practical is applied for only after passing the written exam), then a $500 background-investigation fee and a $200 license fee — other cities/counties differ | $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 statewide process; timelines are set by each municipal licensing authority | 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 | No New York State plumber licensing board — plumbing is licensed municipally (representative program: New York City Department of Buildings) | 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
- Review Iowa's requirements on the Iowa Plumbing and Mechanical Systems Board (Department of Inspections, Appeals, and Licensing) website (linked below) — rules change.
- Ask the Iowa Plumbing and Mechanical Systems Board (Department of Inspections, Appeals, and Licensing) whether it credits a local New York license or your documented experience: New York issues no statewide journeyman plumber license, so there is no state license to verify.
- Otherwise apply as a new applicant: meet Iowa's education/experience requirements and pass the exams it requires.
- Submit the application with fees listed above, and allow for the processing time shown there.

Frequently asked questions
What happens to my New York credential after I'm licensed in Iowa?
Nothing changes it. New York issues no statewide journeyman plumber license, so any local or contractor-level New York credential you hold runs on its own authority's renewal rules, independently of your Iowa license.
