Verdict
Licensure by endorsement
California is not among the states Oregon names for an automatic exam waiver, so this move runs on the Oregon Building Codes Division (BCD) — Department of Consumer and Business Services's individual endorsement or equivalency review rather than a guarantee. Oregon waives its journeyman plumber (JP) exam only for applicants who hold an equivalent or higher journeyman plumber license, earned by testing, in a state Oregon has a JP reciprocity agreement with — currently only Idaho and Montana; every other out-of-state plumber must qualify through experience and training and pass the Oregon journeyman exam. Bring your California license, proof that it is active and in good standing, and your apprenticeship and exam records — and get any discretionary exam or experience credit in writing before you rely on it.
