Plumbing work in California requires a state license. The Contractors State License Board (CSLB) oversees plumbers and assigns them a classification (C-36 for Plumbing Contractor). Before hiring, you can verify a plumber's license status, complaint history, and other details through the CSLB online license lookup tool at cslb.ca.gov.

Most plumbing projects in Los Angeles require a building permit from the Los Angeles Department of Building and Safety. Permit rules vary by project type and scope. Your plumber should advise whether a permit is needed for your specific work, though it's also wise to check with LADBS directly or consult your local building department to confirm requirements for your property.

When hiring a plumber, ask to see their current license, verify it through CSLB, and discuss whether your project requires permits. Get a written contract that outlines the scope of work, timeline, and costs. Make sure you understand what code compliance standards apply to your project.
