LEO county rates, November 2025 edition, effective October 30, 2025. The contracting agent gets LEO's rates before advertising and puts them in the specifications; if the contract isn't awarded or started within 90 days of LEO's determination, LEO must redetermine them (MCL 408.1103). Checked against michigan.gov on October 25, 2026.
LEO lists 3 plumber or pipefitter rates for Mason County, from $60.34 to $72.81 an hour. See all of them.
- LEO prints no wage/fringe split. Derived from its overtime rates (wage = 2 × (time and a half − straight time)), the split would be about $71.28 wage + $1.53 fringe. That's our estimate, not LEO's figure.
One rate, fringe benefits included: $72.81
LEO publishes a single hourly figure that already includes fringe benefits. A contractor can pay it all as wages, or pay part as contributions to bona fide benefit plans for the worker, as long as the two add up to at least $72.81. LEO doesn't publish a base and fringe split, so this page doesn't invent one.
LEO's data note: LEO prints package rates only (wage + fringe at straight time, 1.5x, 2x)
When does this rate change?
- A contract keeps the rates LEO determined for it, unless it isn't awarded or started within 90 days, when LEO redetermines them (MCL 408.1103).
- LEO publishes a new edition every November 1. This page copies the November 2025 edition; Barry, Bay, Benzie and Berrien carry 2026 corrections.
