Arizona Licensing (ROC)
Arizona licenses plumbing contractors through the Registrar of Contractors (ROC). The CR-37 covers residential plumbing; CR-35 and CR-36 cover commercial work. Journeyman plumbers work under a licensed contractor — there's no separate journeyman license at the state level. Apprentices must register with the Arizona State Apprenticeship Office and work under licensed supervision.
