Plumber License Requirements in Alabama

Alabama requires certification through the Plumbers and Gas Fitters Examining Board for work performed for the general public. The board's applicant guidance defines journeyman and master plumber paths, requires companies to register with a principal master designee, and says out-of-state journeyman plumbers may apply to take the Alabama examination if the prior license was issued after an exam with at least a 70 percent passing score.
