California Plumber Salary

The Short Answer

A licensed plumbing contractor in California earns significantly more than an employed journeyman, and the gap widens the longer you stay in the trade. But the numbers depend heavily on where you sit in the career ladder, what region you work in, and whether you are billing for your own business or collecting a W-2.

Employee Pay by Experience Level

Apprentices in California typically start between $18 and $24 per hour depending on the program and region. Union apprentices in the United Association (UA) programs progress through scheduled raises — by the fourth or fifth year, apprentice wages often reach $35 to $45 per hour before benefits.

Journeyman plumbers — employees working under someone else's C-36 license — earn $30 to $55 per hour in most California markets. The Bureau of Labor Statistics reports a median annual wage for plumbers, pipefitters, and steamfitters in California around $72,000 to $78,000 as of recent data, though this figure blends all experience levels. In high-cost metro areas like San Francisco and Los Angeles, experienced journeymen commonly earn $80,000 to $100,000 or more annually, especially on commercial and union jobs.

Lead technicians and foremen running service trucks or supervising crews typically command $45 to $65 per hour, plus overtime. A lead tech running a residential service van in the Bay Area can gross $95,000 to $120,000 annually with overtime and on-call pay.

What Licensed Contractors Earn

This is where the economics shift. As a W-2 employee, you earn an hourly rate while your employer bills the customer two to three times that amount. The spread covers overhead, insurance, and profit — but it is the employer's profit, not yours.

A licensed C-36 contractor billing residential service calls at $125 to $185 per hour (common Bay Area and LA rates) keeps the margin after materials, vehicle costs, insurance, and bond premiums. Solo operators running lean — one truck, no employees, residential service and remodel work — commonly net $90,000 to $150,000 per year. Some clear more.

Contractors who build a crew and take on commercial or new-construction projects operate at a different scale. Revenue often exceeds $500,000 to $1 million annually, though overhead (payroll, workers' comp, vehicles, office) eats a significant share. Net owner compensation in this range typically falls between $120,000 and $250,000.

Regional Variation

California is not one market. A plumber in Bakersfield operates in a different cost and billing environment than one in San Jose.

San Francisco Bay Area and Silicon Valley have the highest billing rates and wages, driven by extreme construction costs and a strong union presence. Journeyman wages in UA Local 38 (San Francisco) are among the highest in the country.

Greater Los Angeles runs slightly lower than the Bay Area but remains well above national averages. The LA market is enormous — more residential service demand, more remodel work, and steady new construction.

San Diego, Sacramento, and Orange County fall in the mid-to-high range. Steady residential growth supports strong demand.

Inland Empire, Central Valley, and rural areas have lower billing rates and wages, but also lower operating costs. Competition from unlicensed operators is more visible in these markets.

The Real Income Jump: Getting Licensed

The most significant pay increase most California plumbers experience is not a raise — it is the transition from employee to licensed contractor. Even at the same volume of work, keeping the full billing rate minus direct costs instead of collecting a fraction as wages typically doubles or triples effective hourly compensation.

The cost to get licensed is relatively modest: around $1,000 to $2,500 all-in for a sole proprietorship (application fee, bond premium, fingerprinting, and license fee). The California Plumber License Guide breaks down every cost and walks you through the transition from employed journeyman to licensed C-36 contractor.
