California Davis-Bacon wage determination changes, 2026
The U.S. Department of Labor published 57 modifications to 28 of California's Davis-Bacon wage determinations between May 18, 2026 and October 15, 2026 that changed, added or removed a rate. Across them, 36 rates went up, 7 went down, 4,633 rows were added and 1,248 removed.
From every revision of each WD on SAM.gov, compared row by row (rate identifier and classification) and read twice. 28 of these modifications are dated May 18, 2026, when DOL reissued most WDs. Totals are base plus fringe. A contract keeps the modification in its bid documents, so a later one only reaches new bids. California prevailing wage rates by county

Questions about California's Davis-Bacon changes
How often do Davis-Bacon wage rates change in California?
Whenever DOL modifies a wage determination. Between May 18, 2026 and October 15, 2026, DOL published 57 modifications to 28 California wage determinations that changed, added or removed a rate; 28 of them are dated May 18, 2026, when DOL reissued most WDs.
Which California Davis-Bacon rate changed the most in 2026?
SHEET METAL WORKER (EL DORADO, PLACER, SACRAMENTO, SUTTER, YOLO AND YUBA COUNTIES) (sheet metal worker) on CA20260019: $46.70 to $95.59 an hour in modification 6, published September 3, 2026, for residential construction.
Does a new modification change the rates on my contract?
A contract keeps the wage determination in its bid documents. Modifications published before bid opening apply to it, though one published less than 10 days before can be left out if the agency finds there isn't time to tell bidders (29 CFR 1.6(c)).
Where are the official California wage determinations?
On SAM.gov. Each row on this page links the new revision there and the one it replaced, and every California rate page names its WD and modification.
