How to Get a Journeyman Plumbing License in California

Dreaming of a stable, well-paying career in the skilled trades? You’re not alone. Many aspiring plumbers in California want to know how to get a journeyman plumbing license in California—but the process can feel overwhelming without clear guidance. Whether you’re just starting out or upgrading from an apprentice, this guide breaks down every step with clarity, confidence, and real-world insights.

What Is a Journeyman Plumbing License in California?

In California, the term “journeyman plumber” isn’t officially used by the state licensing board. Instead, the California State License Board (CSLB) issues a C-36 Plumbing Contractor License, which is the standard credential for independent plumbing work. However, many employers, unions, and training programs still refer to “journeyman” status to describe a plumber who has completed an apprenticeship and can work independently under a licensed contractor.

💡 Key Insight: While California doesn’t have a standalone “journeyman license,” achieving journey-level skills is a critical step toward qualifying for the C-36 license.

According to the U.S. Bureau of Labor Statistics , plumbers in California earn a median annual wage of $65,000+, with top earners making over $95,000—especially in high-demand areas like Los Angeles, San Diego, and the Bay Area.

Step-by-Step: How to Get a Journeyman Plumbing License in California

Even though California doesn’t issue a formal journeyman license, you’ll need journey-level experience to qualify for the C-36 Plumbing Contractor License. Here’s how to build that foundation:

1. Meet Basic Eligibility Requirements

Before you begin, ensure you meet these baseline criteria:

• Be at least 18 years old
• Have a valid Social Security number or ITIN
• Possess a high school diploma or GED
• Be legally authorized to work in the U.S.

2. Complete a Plumbing Apprenticeship (4–5 Years)

The most common path to journey-level status is through a state-recognized apprenticeship program. These combine on-the-job training with classroom instruction.

Top Apprenticeship Options in California:

• UA (United Association) Local Unions – e.g., UA Local 441 (Sacramento), UA Local 78 (San Diego)
• Associated Builders and Contractors (ABC)
• Independent plumbing contractors registered with the CSLB as training providers

✅ Typical Apprenticeship Structure:

• 8,000+ hours of supervised fieldwork (approx. 4 years full-time)
• 500+ hours of classroom instruction
• Covers pipefitting, drainage systems, gas lines, code compliance (California Plumbing Code), and safety

📌 Pro Tip: Keep detailed logs of your work hours. The CSLB may request documentation when you apply for your contractor license.

3. Gain Journey-Level Experience

After completing your apprenticeship, work as a journey-level plumber under a licensed C-36 contractor. This experience is essential—you’ll need at least 4 years of full-time journey-level experience within the last 10 years to qualify for the C-36 exam.

⚠️ Note: “Journey-level” means you perform plumbing tasks without direct supervision, though you still work for a licensed contractor.

4. Prepare for the C-36 Plumbing Contractor License Exam

Once you have the required experience, you can apply to take the CSLB’s C-36 exam, which has two parts:

1. Trade Knowledge Exam – 115 questions on plumbing systems, codes, installation, and repairs
2. Law & Business Exam – Covers contracts, licensing laws, safety, and business practices

📚 Study Resources:

• CSLB’s official C-36 Study Guide
• Contractor Training Centers (e.g., Builders License Training Institute)
• Practice exams from Gold Coast Schools or 20/20 Prep

🎯 Passing Score: You need 72% or higher on both sections.

5. Submit Your CSLB Application

Gather these documents:

• Completed Application for Original Contractor’s License (Form CSLB 11-R)
• Certification of Work Experience (signed by a licensed contractor or employer)
• $450 application fee (as of 2025)
• Fingerprinting for background check

Processing time: 6–8 weeks (can be longer during peak periods).

6. Pass the Exam & Get Licensed

Once approved, you’ll receive an exam date. After passing both sections:

• Pay the $200 initial license fee
• Obtain a $25,000 contractor bond
• Secure workers’ compensation insurance (if you have employees)

Your C-36 Plumbing Contractor License will be issued within 2–4 weeks.

Common Mistakes to Avoid

• Misreporting work experience: The CSLB verifies experience. False claims = automatic disqualification.
• Skipping the Law & Business exam: Many plumbers focus only on trade knowledge and fail the business section.
• Not renewing on time: Licenses expire every 2 years. Late renewal = penalties or retesting.
