Moving to Alabama as a journeyman plumber: every state's rule

Alabama certifies Journeyman Plumbers statewide through the Plumbers and Gas Fitters Examining Board in Homewood; under Ala. Code § 34-37-6(a) a Board certificate is required to engage in plumbing anywhere in the state, and the Board's pages describe no county or city plumber licensing. A new applicant must complete at least two years as a registered Apprentice Plumber (or a Board-approved apprentice training program plus registered apprentice time equal to two years, or two years of documented equivalent experience approved at a Board meeting), then pass the Board's journeyman plumber exam, which since January 1, 2023 tests the 2021 International Plumbing Code. After passing, the applicant has 90 days to pay the certification fees or must re-test. Certificates are issued for the calendar year and renew each October 1 - December 31, with continuing education due by November 1 to avoid a deficiency plan and fee. The Board has no journeyman reciprocity agreement with any state; an out-of-state journeyman may sit the Alabama exam directly if the origin license was earned by an exam passed at 70% or better, is active and in good standing, and is verified by the origin agency.
