Washington to Alabama: master plumber license reciprocity
Washington does not issue a statewide master plumber license, so there is nothing to transfer. Here is Alabama's standard path for out-of-state applicants.
Your origin state does not issue a statewide license at this level, so there is no license to transfer. The destination's standard out-of-state path is shown; expect to meet it in full.
Reference only, not legal advice. Rules change; confirm with the licensing board before you apply. Full disclaimer.
Out-of-state master plumber: direct admission to the Alabama master exam (states other than Mississippi)
Your out-of-state credentials give no advantage. You meet the destination's requirements from scratch.
A master plumber licensed in a state other than Mississippi is admitted to the Alabama Master Plumber examination on the strength of the origin license, without first holding an Alabama journeyman certificate for a year. The Board's conditions are that the out-of-state master license 'must have been issued based on successful completion of an exam with a minimum score of 70%', 'must be active and in good standing with no unresolved disciplinary issues', and that the origin agency complete the Board's Request for Verification of License/Registration form or provide the same information on letterhead. The applicant files the Examination Packet for Out-of-State Applicants, passes the master plumbing exam on the 2021 International Plumbing Code and, since January 1, 2026, the Board's business law exam, then has 90 days to submit the Master Pass Packet with the certification fee. A master who will own or run a plumbing business must also register the company with the Board under Ala. Code § 34-37-6(b) and be named its Principal Master, with annual business renewals under rule 720-X-17-.01.
Fees are set in the Board's rules (Ala. Admin. Code r. 720-X-4-.01): $160 master exam fee, $100 business law exam fee, $50 initial application processing fee and $175 initial master certificate fee. Both exams are open book, given by Prov, and require 70%. The Examination Packet for Out-of-State Applicants is at https://pgfb.alabama.gov/wp-content/uploads/2023/01/Exam-App-Out-of-State-01-26.pdf; the Board's phone is (205) 945-4857. The Board admits an out-of-state master to the Alabama master exam on a verified origin license; the one-year Alabama journeyman holding period is the in-state qualifier.

How Alabama licenses master plumbers
Alabama master plumber · “Master Plumber (annual certificate)”
Statewide license
Issued by Alabama Plumbers and Gas Fitters Examining Board
Alabama certifies Master Plumbers statewide through the Plumbers and Gas Fitters Examining Board; a master plumber may register as the Principal Master for a plumbing business, and every company doing plumbing work in Alabama must register with the Board and name one. To sit the master exam an applicant must have been certified as a Journeyman Plumber for at least one year (the Board describes this as one year of current work experience). Effective January 1, 2026, master-level applicants must pass both the plumbing exam (2021 International Plumbing Code) and a separate business law exam, and after passing have 90 days to pay the certification fees. Certificates are annual, renewing October 1 - December 31 with continuing education due by November 1. The Board's only reciprocal agreement, effective January 1, 2026, is with the Mississippi Board of Contractors at the master level; a master from any other state may sit the Alabama master exam directly if the origin license was earned by exam at 70% or better, is active and in good standing, and is verified by the origin agency.
Why Washington has nothing to transfer
Washington master plumber
No individual license at this level
Issued by Washington State Department of Labor & Industries, Plumber Certification Program
Washington has no master plumber license. WAC 296-400A-010 lists every certificate the state issues (journey level PL01, residential PL02, residential service PL04, pump and irrigation PL03, domestic well PL03A, backflow PL30, and trainee), and the Journey Level Plumber certificate is the highest credential an individual can hold; the only add-on is the Medical Gas Piping Installer endorsement (MG01), which is a specialty, not a supervisory tier. Since July 1, 2021 a business that advertises, bids or performs plumbing work must hold a Plumbing Contractor license under RCW 18.106.400, but that is a business registration rather than a person-held trade license: the firm registers with the Department of Revenue, files a $6,000 surety bond, carries $250,000 combined (or $200,000/$50,000) liability insurance, pays a $148.10 license fee plus $53.20 to designate a Washington-certified plumber who works for the firm full time, and renews every two years; no exam is taken by the owner. An out-of-state master plumber therefore has nothing to transfer to at this level. To work as a plumber they obtain the journey level (PL01) certificate through the journeyman path (Idaho reciprocity or license review plus the Washington exam), and to contract they form a business and license it as a plumbing contractor with themselves or an employee as the designated certified plumber.
