Figures above are computed over the 54 hourly records in the table below, which is the first page of a larger set. They are not a statewide average of all sprinkler fitters in Illinois. Most recent determination in this set: May 21, 2026.
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.

WageFinder holds more sprinkler fitter records for Illinois than fit on this page. Open a county below, or search all Illinois sprinkler fitters.
Sprinkler fitters install fire suppression piping, heads, standpipes and the associated valves and alarms. The classification is distinct from both plumber and pipefitter on most determinations because fire protection work is separately licensed in most states.
In this Illinois result set the work appears under 2 distinct classification names.
Prevailing wage is set county by county. These are the Illinois counties with sprinkler fitter records in the set above — open one to see every classification on that county's determination, not just this trade.
Across the 54 federal and state-funded determination records WageFinder lists for sprinkler fitters in Illinois, total prevailing wage runs from $80.76 to $102.50 per hour, median $84.01. 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.
The total prevailing wage shown is the base hourly rate plus the fringe benefit rate. Of the 54 Illinois records on this page, 54 list a fringe amount separately, with a median of $30.25 per hour — roughly 36% 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.
This page lists sprinkler fitter records for 26 counties in Illinois: Cook, Putnam, Randolph, Richland, Rock-Island, Saline, Sangamon, Schuyler, Scott, Shelby, St.-Clair, Stark, and others. Determinations that apply statewide appear under a statewide entry rather than a named county.
The most recent determination in this set is dated May 21, 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.
