Thinking about becoming a plumber in California but don’t have a license yet? You’re not alone. Many aspiring tradespeople wonder how to get a plumbing license in California without a license—especially if they’re just starting out or coming from another state. The good news? While you can’t legally perform plumbing work for pay without proper licensing in California, there is a clear, legal path to earn your license—even if you’re starting from zero. This guide walks you through every step, requirement, and insider tip to help you get certified the right way.
Can You Legally Work as a Plumber in California Without a License?
Short answer: No—but with important exceptions.
California law (Business and Professions Code §7028) strictly prohibits anyone from performing plumbing work for compensation without a valid contractor’s license issued by the California Contractors State License Board (CSLB)—if the total job cost is $500 or more (including labor and materials).
However, you can:
Work as an employee under a licensed contractor (no personal license needed).
To qualify, you must prove at least 4 years of full-time journey-level experience in plumbing within the last 10 years.
📌 Note: If you’re new to the trade, you’ll need to gain this experience before applying—usually as an apprentice or employee under a licensed C-36 contractor.
Step-by-Step: How to Get Your C-36 Plumbing License in California (Even With No License)
Here’s the official roadmap—approved by the CSLB—for going from unlicensed to fully licensed:
Step 1: Gain Qualifying Experience (4 Years Minimum)
You must document 48 months of practical plumbing experience at the journeyman level or above. This can include:
Working under a licensed C-36 contractor.
Military plumbing experience (with documentation).
Completing an accredited apprenticeship program (e.g., through UA Plumbers & Pipefitters).
✅ Pro Tip: Keep detailed records—pay stubs, W-2s, affidavits from supervisors, and project logs. The CSLB may audit your experience.
Step 2: Find a Qualifying Individual (If Applying as a Business)
If you’re forming an LLC or corporation, you’ll need a Qualifying Individual—someone with the required experience who will be responsible for the license. This can be you or a trusted employee.
Step 3: Submit Your CSLB Application
Complete the Original Contractor’s License Application (Form 900A) and pay the $450 fee. Include:
Proof of experience (Form 900B + supporting documents).
A $25,000 surety bond.
Workers’ comp insurance (if you have employees).
Processing takes 6–8 weeks on average.
Step 4: Pass the CSLB Exams
Once approved, you’ll schedule two exams:
Law & Business Exam – Covers contracts, liability, and business practices.
Both are multiple-choice, 115 questions, 3 hours each. You need 72% to pass.
📚 Study Resources: Use the CSLB’s official study guides and consider prep courses from reputable providers like Contractor Training Center or Gold Coast Schools.
Step 5: Get Fingerprinted & Approved
After passing both exams, submit fingerprints for a background check. Certain criminal convictions may disqualify you, but many are reviewed case-by-case.
Step 6: Receive Your License!
Once cleared, you’ll get your C-36 license number. You can now legally operate as a plumbing contractor in California.
⏱️ Timeline: Most applicants complete this process in 12–24 months, depending on experience and exam readiness.
