How to Become a Plumber in California
To become a licensed plumber in California, individuals must obtain a C-36 Plumbing Contractor license from the Contractors State License Board (CSLB). This requires applicants to be at least 18 years old, possess a high school diploma or GED, and demonstrate four years of journeyman-level experience. After meeting these prerequisites, candidates must pass both the C-36 Plumbing Contractor Examination and the Law and Business Examination, undergo a criminal background check, and secure a contractor's bond. California has reciprocity agreements with Arizona, Louisiana, and Nevada, which may waive the trade exam for eligible applicants, though the Law and Business exam is still mandatory.
