Oregon to Alabama: master plumber license reciprocity

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.

Oregon has no master plumber license and no other person-held plumbing credential above journeyman. ORS 693.095 permits the State Plumbing Board to adopt rules for a 'supervising plumber' license, but no such rule exists in OAR chapter 918, division 695, and the Building Codes Division's license table lists only the Journeyman Plumber (JP) and three limited specialty licenses (residential water-heater, water-treatment and solar heating and cooling installer) as individual plumbing licenses; the Journeyman Plumber is therefore the highest license an individual can hold. The business-side credential is the Plumbing Business (PB) license under ORS 447.040, issued by the Building Codes Division to a firm that already holds a Construction Contractors Board (CCB) license: the owner or corporate officer files the Contractor/Business License Application (form 440-2888) with a $150 non-refundable fee and the CCB number, no signing supervisor or qualifying-person experience is designated for a plumbing business, no exam is taken, and the license renews on a three-year cycle (all PB licenses next expire July 1, 2029). A plumbing business license 'does not authorize the contractor to work as a journeyman plumber,' and the business may not let anyone perform journeyman work without an individual JP license. An out-of-state master plumber therefore has nothing to transfer to at this level: to work with the tools they obtain the Journeyman Plumber license through the journeyman path (Idaho or Montana reciprocity, or experience credit plus the Oregon exam), and to contract they register a business with the Secretary of State, license it with the CCB, and add the $150 BCD Plumbing Business license.
