Plumber License from Texas to Washington: Does It Transfer? (2026)
Last verified: 2026-07-21 · source: Washington State Department of Labor & Industries (L&I) — Plumber Certification Program ↗
A plumbing license transfers from Texas to Washington by endorsement — there is no automatic reciprocity, but you do not start over. Apply to the Washington State Department of Labor & Industries (L&I) — Plumber Certification Program, verify your Texas license, and meet Washington's endorsement requirements. Washington waives its journey level (journeyman) plumber examination only for a plumber who holds a current Idaho journey level plumber certificate — the sole reciprocal state; L&I reviews the Idaho credential and issues the Washington certificate without exam. Every other out-of-state plumber must pass the Washington plumber exam; out-of-state trainee/apprenticeship hours are not accepted toward Washington certification, though a one-time 120-day temporary permit lets a non-reciprocal applicant work while awaiting the exam.

Verdict
Licensure by endorsement
Texas is not among the states Washington names for an automatic exam waiver, so this move runs on the Washington State Department of Labor & Industries (L&I) — Plumber Certification Program's individual endorsement or equivalency review rather than a guarantee. Washington waives its journey level (journeyman) plumber examination only for a plumber who holds a current Idaho journey level plumber certificate — the sole reciprocal state; L&I reviews the Idaho credential and issues the Washington certificate without exam. Every other out-of-state plumber must pass the Washington plumber exam; out-of-state trainee/apprenticeship hours are not accepted toward Washington certification, though a one-time 120-day temporary permit lets a non-reciprocal applicant work while awaiting the exam. Bring your Texas 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.
