Plumber License from Idaho to Texas: Does It Transfer? (2026)
Last verified: 2026-07-21 · source: Texas State Board of Plumbing Examiners (TSBPE) ↗
A plumbing license transfers from Idaho to Texas by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the Texas State Board of Plumbing Examiners (TSBPE), verify your Idaho license, and meet Texas's endorsement requirements. Texas waives its journeyman plumber examination only for plumbers currently licensed in Louisiana or Arkansas, who may qualify for a reciprocal Texas license; every other out-of-state journeyman or master plumber (currently licensed and having held that license at least two years) must apply for an Out-of-State Examination and pass the Texas computer-based (Pearson VUE) written exam plus the practical journeyman exam.

Verdict
Licensure by endorsement
Idaho is not among the states Texas names for an automatic exam waiver, so this move runs on the Texas State Board of Plumbing Examiners (TSBPE)'s individual endorsement or equivalency review rather than a guarantee. Texas waives its journeyman plumber examination only for plumbers currently licensed in Louisiana or Arkansas, who may qualify for a reciprocal Texas license; every other out-of-state journeyman or master plumber (currently licensed and having held that license at least two years) must apply for an Out-of-State Examination and pass the Texas computer-based (Pearson VUE) written exam plus the practical journeyman exam. Bring your Idaho license, proof that it is active and in good standing, and your apprenticeship and exam records — and get any discretionary exam or experience credit in writing before you rely on it.
What changes, Idaho → Texas
| Idaho (current) | Texas (destination) | |
|---|---|---|
| Application fee | Idaho DOPL journeyman plumber license fees are prorated and reciprocity applicants pay the standard application/license fee, but the exact figure could not be confirmed on a directly loaded DOPL fee schedule because every idaho.gov host was unreachable (connection refused) from the research environment; one search result cited a $147 three-year license fee and another cited roughly $29 license / $22 renewal — the two conflict, so no figure is asserted. Confirm on the DOPL fee schedule | $40 ($40 non-refundable out-of-state journeyman examination processing fee to TSBPE ($25 for master); a separate computer-based test fee is payable to Pearson VUE on approval, plus IdentoGO fingerprint costs and the license issuance fee once passed; Louisiana/Arkansas applicants use the Reciprocal License Verification pathway) |
| Processing time | No board-stated processing time in weeks | 4–6 weeks (TSBPE states typical processing of 30-45 days for straightforward applications; longer with criminal history or unclear immigration status) |
| Licensing authority | Idaho Division of Occupational and Professional Licenses (DOPL) — State Plumbing Board | Texas State Board of Plumbing Examiners (TSBPE) |
