Public works certified payroll in Napa County

What the data shows

These figures come from WellStanding's collection of DIR's PWC-100 project registration data, as of October 23, 2026, matched to CSLB license records. Collection paused from July 7 to September 3, 2026, so counts are a floor, not a total. They count contractors licensed in Napa County who were newly listed on public works project registrations between 2026-06-26 and 2026-10-23. Each listing starts a certified payroll clock: eCPRs to DIR at least monthly on non-exempt projects, and the federal WH-347 weekly where federal funds apply.

The awarding body sets the portal story. The state sets the eCPR story. They are separate duties: a portal upload answers the awarding body's monitoring, and the state requires its own filing regardless, spelled out with the primary source in the duties below.

Prevailing wage rates for your county

Prevailing wage determinations are set by craft and by county. Before the first certified payroll on a new project, pull the current determination for Napa County from DIR's prevailing wage determinations and check every classification you will use. Rate and classification mistakes are the most expensive kind: they surface months later as wage assessments, not as bounced uploads.

Your filing duties on these projects

• Direct DIR eCPR filing. On a registered public works project you submit electronic certified payroll records directly to DIR at least monthly, or more often when the contract says so (Labor Code 1771.4). DIR is explicit that submitting certified payroll records to other agencies "does not put you in compliance with the state unless you submit eCPRs directly to DIR" (DIR eCPR FAQ).
• Federal weekly payroll. Contracts subject to the Davis-Bacon and Related Acts require payroll information every week, each submission with a signed Statement of Compliance (U.S. Department of Labor).
• Records on demand. You keep certified records and produce them within 10 days of receiving a written request. Miss it and you forfeit $100 for each calendar day, or part of a day, for each worker, and the Division of Labor Standards Enforcement can request that the penalty be withheld from progress payments then due (Labor Code 1776). From January 1, 2027, SB 909 (Chapter 660, Statutes of 2026) raises that penalty to $140 per worker per calendar day; what SB 909 changes.
