## What the data shows

These figures come from DIR's public PWC-100 project registrations, matched to CSLB license records. They count contractors licensed in San Joaquin County who were newly listed on public works project registrations between 2026-06-26 and 2026-10-18. 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.

## Trade mix among newly listed San Joaquin County contractors

- General building (B): 23 contractors
- General engineering (A): 17 contractors
- Electrical (C-10): 13 contractors
- Flooring (C-15): 4 contractors
- Hazardous substance removal (HAZ): 4 contractors
- Doors and gates (D-28): 4 contractors

## Awarding bodies San Joaquin County contractors were listed for

- [San Joaquin County - Purchasing & Support Services](https://wellstanding.com/requirements/san-joaquin-county-purchasing-support-services/): 8 contractor listings
- City of Lathrop: 4 contractor listings
- Stockton East Water District: 2 contractor listings
- Alameda Unified School District: 2 contractor listings
- [County of Sacramento](https://wellstanding.com/requirements/county-of-sacramento/): 2 contractor listings
- Lodi Unified School District: 1 contractor listings

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 San Joaquin County from [DIR's prevailing wage determinations](https://www.dir.ca.gov/OPRL/DPreWageDetermination.htm) 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, under your own PWCR registration ([Labor Code 1771.4](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=LAB&sectionNum=1771.4)). DIR is explicit that submitting certified payroll to the awarding body, the prime, or a portal "does not put you in compliance with the state unless you submit eCPRs directly to DIR" ([DIR eCPR FAQ](https://www.dir.ca.gov/Public-Works/ecprfaq.html)).
- **Federal WH-347 weekly** when federal money is in the project, with the Statement of Compliance signed ([U.S. Department of Labor](https://www.dol.gov/agencies/whd/forms/wh347)).
- **Records on demand.** A written request for certified payroll records starts a 10 day clock. Miss it and the penalty is $100 per worker per calendar day, enforceable by withholding from your progress payments ([Labor Code 1776](https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=LAB&sectionNum=1776)). From January 1, 2027, [SB 909](https://leginfo.legislature.ca.gov/faces/billTextClient.xhtml?bill_id=202520260SB909) (Chapter 660, Statutes of 2026) raises it to $140 per worker per calendar day; [what SB 909 changes](https://wellstanding.com/guides/sb-909-prevailing-wage-penalty-increases-2027/).
