Best Plumbing Schools in California

If you want to become a plumber in California, your first step is choosing the right training program. In this state, plumbing is a licensed trade. That means you can't legally work as a journeyman or contractor without meeting the California Contractors State License Board (CSLB) requirements.

The right school helps you build skills, log required work hours, and prepare for licensing exams. Below, you'll find some of the best options in California-plus what to check before enrolling.

How Plumbing Licenses Work in California

California does not offer a separate "plumbing license" for entry-level workers. Instead:

1. You start as an apprentice or entry-level worker under supervision.
2. You log at least four years (8,000 hours) of work experience in the trade.
3. To work independently on projects over 00 in labor and materials, you must get a C-36 Plumbing Contractor license from the CSLB.

State Rule: Per the CSLB, "A C-36 Plumbing contractor fabricates, installs, and repairs piping, fixtures, and other apparatus for bringing in water, removing waste, and other plumbing uses" ¹.

Training at an accredited trade school can help you gain entry-level skills, get hired faster, and complete your apprenticeship more efficiently.

Before you sign up, check for:

• Accreditation - Look for state-approved schools or community colleges with plumbing programs.
• Hands-on training - The best programs combine classroom and lab time.
• Connections with apprenticeship programs - This can help you find paid training.
• Flexible schedules - Night or weekend classes may be available.
• Exam prep - Some courses cover CSLB test topics directly.
