How much do sprinkler fitters earn on prevailing wage jobs in Washington?
Every row below is one wage determination line: a sprinkler fitter 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.

Sprinkler Fitter prevailing wage questions
What is the prevailing wage for a sprinkler fitter in Washington?
Across the 36 federal-funded determination records WageFinder lists for sprinkler fitters in Washington, total prevailing wage runs from $34.12 to $102.69 per hour, median $72.73. 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 sprinkler fitter rate include benefits?
The total prevailing wage shown is the base hourly rate plus the fringe benefit rate. Of the 36 Washington records on this page, 34 list a fringe amount separately, with a median of $28.58 per hour — roughly 39% 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.
