How much do plumbers earn on prevailing wage jobs in Hawaii?
Every row below is one wage determination line: a plumber 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.
What does the plumber classification cover?
Plumbers install and repair potable water, sanitary waste, vent and storm systems, plus the fixtures they serve. Determinations often list plumbers and pipefitters as one combined classification and sometimes as two — check which one your determination uses before you price the work, because the rates are rarely identical.
Work typically covered
- Water supply and distribution
- Sanitary waste and vent
- Storm drainage
- Fixture setting
- Backflow and water heaters
Also listed as
- Plumber/Pipefitter
- Plumber and Steamfitter

Plumber prevailing wage questions
What is the prevailing wage for a plumber in Hawaii?
Across the 20 federal-funded determination records WageFinder lists for plumbers in Hawaii, total prevailing wage runs from $87.02 to $87.02 per hour, median $87.02. 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 plumber rate include benefits?
The total prevailing wage shown is the base hourly rate plus the fringe benefit rate. Of the 20 Hawaii records on this page, 20 list a fringe amount separately, with a median of $33.19 per hour — roughly 38% 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.
