How much do millwrights make in California in 2026?

The median millwright in California earns $77,950 a year, which works out to roughly $37.48 an hour based on a standard 2,080-hour work year. That figure sits well above the national median for this trade, reflecting California's high cost of living and the concentration of heavy industrial, manufacturing, and food-processing facilities that keep millwrights busy year-round.

Pay spreads wide depending on experience and employer. The 25th percentile — workers who are earlier in their careers or working for smaller shops — comes in at $61,310 a year, or about $29.48 an hour. The 75th percentile reaches $109,190 a year, roughly $52.50 an hour. That's a gap of nearly $48,000 between the lower and upper ends of the middle range, which tells you how much room there is to grow once you've stacked years on the tools and moved into more complex machinery work.

Millwrights in California work across a range of industries: food and beverage processing plants in the Central Valley, semiconductor and aerospace manufacturing in the Bay Area and Los Angeles Basin, paper mills, cement plants, utilities, and large warehousing operations. The specific industry matters more for millwrights than for some other trades because machinery complexity and maintenance schedules vary drastically. A millwright aligning precision turbines at a power plant is doing different work — and getting paid differently — than one setting up conveyor systems in a distribution center.

Geography inside California also moves the needle. The Bay Area and Los Angeles metro markets tend to pay more, partly because the cost of living forces wages up and partly because the density of advanced manufacturing and tech-adjacent industrial facilities drives demand. Inland Empire logistics hubs have added steady millwright work in recent years as warehouse construction boomed. Central Valley food processing plants are another consistent source of employment, though wages there often trail the coastal metros.

Overtime is real money in this trade. Millwrights are frequently called for scheduled shutdowns — planned outages where entire production lines go down for maintenance — which can compress weeks of work into a few intense days with significant overtime pay. During a major turnaround, a millwright working 60-hour weeks could see weekly earnings climb 50% or more above their base rate. California's overtime laws (daily OT after 8 hours, double time after 12) can make those shutdown weeks especially lucrative compared to states with only weekly OT thresholds.

Apprenticeship is the standard entry path. A millwright apprenticeship typically runs four to five years and combines on-the-job hours with related technical instruction covering rigging, precision alignment, hydraulics, pneumatics, and blueprint reading. Wages during apprenticeship are set as a percentage of journey-level scale and step up as you progress. Completing your apprenticeship and earning journey-level status is the single biggest jump in pay most millwrights will see in their careers.

Some millwrights in California work under collective bargaining agreements, and those workers should check their local agreement directly for scale, fringe benefits, and overtime rules — that document will give you the most accurate picture of your total compensation. The BLS figures here reflect the full mix of union and non-union workers across the state.

To push your pay toward the 75th percentile and beyond, the clearest paths are specialization and portability. Millwrights who develop expertise in precision laser alignment, vibration analysis, or specific machinery types — paper machines, turbines, CNC equipment — make themselves harder to replace and easier to move between high-paying employers. Welding certifications also add leverage, since many industrial sites want millwrights who can handle their own fit-up and repair work without calling a separate crew.

The BLS OEWS data used here comes from the May 2025 survey and captures base wages reported by employers. It does not include the value of employer-paid health insurance, pension contributions, or tool and vehicle allowances, all of which can add meaningful value to a total compensation package — particularly on larger industrial sites where those benefits are negotiated into the deal.
