Full re-application
There is nothing at the state level to transfer your Ohio license into: Arizona issues no statewide plumbing license, so plumbers there are licensed at the contractor level or by cities and counties. Not applicable at the journeyman level — Arizona issues no state journeyman (or master) plumber license, so there is no state journeyman trade exam to waive or require. Plumbing is regulated only at the contractor level by the Arizona Registrar of Contractors (e.g., C-37 commercial plumbing, plus residential and dual plumbing classifications); individual journeymen and apprentices are not state-licensed and work under a licensed contractor. At the contractor level, A.R.S. § 32-1122 lets the Registrar waive the trade exam for a qualifying party who held an Arizona license in the same classification within five years, and Form RC-L-200G extends a comparable out-of-state trade-exam waiver, but the Arizona Statutes and Rules Exam (SRE) is never waived.. The move is a local or contractor-board application, not a reciprocity filing — identify the authority that governs your worksite and work from its exam, experience, and fee rules. Your Ohio license may count toward a local experience requirement, but Arizona has no state credential for it to reciprocate into.
