Thinking about becoming a journeyman plumber in California—or already on the path and wondering what your paycheck might look like? You’re not alone. With California’s booming construction industry and constant demand for skilled tradespeople, plumbing remains a stable and rewarding career. But exactly how much does a journeyman plumber make in California? In this guide, we’ll break down real salary data, regional differences, and factors that can boost your earnings—all backed by trusted sources and industry insights.
What Is a Journeyman Plumber?
Before diving into salary figures, let’s clarify what a journeyman plumber actually is. In the U.S. trades system, a journeyman is a licensed professional who has completed an apprenticeship (typically 4–5 years) and passed a state or local licensing exam. Unlike apprentices, journeymen can work independently—though they cannot pull permits or run their own plumbing business without becoming a master plumber.
In California, plumbing licenses are regulated at the state level by the California State License Board (CSLB). While California doesn’t issue a standalone “journeyman” license like some states, the term is still widely used to describe licensed plumbers working under a C-36 (Plumbing) contractor license.
Average Journeyman Plumber Salary in California (2025 Data)
According to the U.S. Bureau of Labor Statistics (BLS) and industry reports from ZipRecruiter and Indeed, the average annual salary for a journeyman plumber in California in 2025 is:
Average Annual Salary: $72,000 – $95,000
Hourly Wage Range: $35 – $46/hour
These figures can vary significantly based on location, experience, employer type (union vs. non-union), and specialization (e.g., commercial vs. residential plumbing).
💡 Pro Tip: Union plumbers in California—especially those affiliated with UA Local 342 (San Francisco) or UA Local 78 (Los Angeles)—often earn 15–25% more than non-union counterparts due to negotiated wage scales and benefits.
