Thinking about becoming a plumber in California—or just wondering if it’s a lucrative career? You’re not alone. With housing demand high and infrastructure constantly evolving, skilled trades like plumbing are more essential than ever. So, how much does a plumber make in California? The answer isn’t one-size-fits-all—but we’ll break down real numbers, regional differences, and what you can do to maximize your earnings in the Golden State.
What Is the Average Plumber Salary in California?
According to the U.S. Bureau of Labor Statistics (BLS) May 2023 data, the average annual wage for plumbers in California is $75,810—significantly higher than the national average of $61,550. That translates to roughly $36.45 per hour for full-time work.
But averages only tell part of the story. Entry-level plumbers may start around $50,000, while experienced, licensed master plumbers in high-cost areas like San Francisco or Los Angeles can earn over $100,000 annually.
💡 Pro Tip: Union plumbers (e.g., members of UA Local 342 or Local 393) often earn 15–25% more than non-union counterparts due to negotiated wage scales and benefits.
How Do Salaries Vary by Region in California?
Location dramatically impacts plumber earnings. Here’s a snapshot of average annual salaries across key California regions (2023–2024 estimates):
| San Francisco Bay Area | $92,500 | $44.47 |
| Los Angeles Metro | $84,200 | $40.48 |

| Sacramento | $72,300 | $34.76 |
| Central Valley (Fresno/Bakersfield) | $65,100 | $31.30 |
Why the gap? High cost of living, union density, and demand for emergency or specialty plumbing (e.g., earthquake retrofitting, smart home installations) drive up wages in urban centers.
For context, California’s plumbing industry is regulated by the California State License Board (CSLB), which requires licensing for anyone charging over $500 for labor and materials combined. Licensed professionals typically command higher rates—another reason to pursue certification early.
