LEO county rates, November 2025 edition, effective November 3, 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 2 insulator rates for Washtenaw County, from $63.85 to $75.80 an hour. See all of them.
This rate covers only part of Washtenaw County. LEO's wording: “Bridgewater, Dexter, Freedom, Lima, Lindon, Manchester, Sharon and Sylvan” Rates for the rest are in the table below.
- LEO prints no wage/fringe split. Derived from its overtime rates (wage = 2 × (time and a half − straight time)), the split would be about $40.00 wage + $23.85 fringe. That's our estimate, not LEO's figure.
One rate, fringe benefits included: $63.85
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 $63.85. 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.

Davis-Bacon insulator rate in Washtenaw County
Federally funded or assisted construction here uses the U.S. Department of Labor's wage determinations. Contracts that already require Davis-Bacon rates are exempt from Michigan's Act, so a Davis-Bacon job uses the federal rate (MCL 408.1102(1)).
We don't put a federal figure next to LEO's here, because the federal determination lists more than one rate for this trade here. The federal rows for this trade are below; match the classification to the work.
