How much do boilermakers earn on prevailing wage jobs in California?
Every row below is one wage determination line: a boilermaker classification, in one county, for one construction type, under one funding source. The rate that applies to your project is the row whose county, construction type and funding source all match it — a Highway rate does not apply to a Building project in the same county, and a state determination does not substitute for a federal one.

Boilermaker prevailing wage questions
What is the prevailing wage for a boilermaker in California?
Across the 100 federal and state-funded determination records WageFinder lists for boilermakers in California, total prevailing wage runs from $21.05 to $107.98 per hour, median $97.39. There is no single statewide figure: each county's determination sets its own rate, and the same county can carry different rates for Building, Highway, Heavy and Residential work.
Does the boilermaker rate include benefits?
The total prevailing wage shown is the base hourly rate plus the fringe benefit rate. Of the 100 California records on this page, 100 list a fringe amount separately, with a median of $41.44 per hour — roughly 43% of the median total. The rest list no separate fringe, meaning the base rate is the whole obligation. Fringe can be paid as bona fide benefit plan contributions, as cash added to the paycheck, or as a mix of both.
Which California counties have boilermaker rates?
This page lists boilermaker records for 21 counties in California: Alameda, Alpine, Amador, Butte, Calaveras, Colusa, Contra-Costa, Del-Norte, El-Dorado, Fresno, Glenn, Humboldt, and others. Determinations that apply statewide appear under a statewide entry rather than a named county.
How current are these California boilermaker rates?
The most recent determination in this set is dated May 20, 2026. WageFinder re-reads the official sources weekly, but the date that matters for compliance is the determination date on the document itself, which is shown on every wage detail page and links back to the government source.
