California CA Plumbing License Requirements and Plumber License Verification, Renewal and Application

California Contractors’ State Licensing Board are the ones who you must apply with to become a licensed Plumbing Contractor or Journeyman Plumber in California. The Contractors State License Board (CSLB) protects consumers by licensing and regulating California’s construction industry. There are about 300,000 licensed contractors in the state, in 43 different licensing classifications. In addition to educating consumers about contractors and construction law, CSLB activities include administering examinations to test prospective licensees, issuing licenses, investigating complaints against licensed and unlicensed contractors, issuing citations, suspending or revoking licenses, and seeking administrative, criminal, and civil sanctions against violators. In fiscal year 2012-13, CSLB helped recover nearly $44 million in ordered restitution for consumers (excerpt from The California Contractors’ State Licensing Board official web site).
