Certified payroll for drywall subs (C-9) in California
What certified payroll actually looks like in the drywall trade on California public works, plus live registration activity for the classification.
Data updated 2026-07-01
The drywall trade's certified payroll reality
Drywall crews cross three determination lines in a normal week: carpenter rates for framing and hanging, taper rates for finishing, and laborer rates for scrap-out and stocking. The cheapest mistake is booking tapers as hangers or everyone as one blended rate; the determination does not blend. Piece-rate pay, common in drywall, does not suspend prevailing wage: piece earnings still have to compute out to at least the determination package per hour, and your certified payroll must show real hours with real effective rates. School district work, the steadiest public drywall demand, is bond-cycle driven, so crews staff up fast and payroll complexity spikes exactly when the filing habit is newest.
Whatever the craft mix, the mechanics are the same statewide: rates come from the project county's published determination (DIR lookup), the eCPR goes directly to DIR on non-exempt projects, and the federal WH-347 rides along weekly where federal funds apply. The full picture is in the complete guide.
