California Prevailing Wage

What is California prevailing wage?

California prevailing wage is the minimum pay rate (basic hourly rate plus fringe benefits) that contractors and subcontractors must pay workers on public works projects in the state. Rates are set by the DIR (Department of Industrial Relations) and vary by trade, county, and project type.

If you bid a school, municipal, state, or other publicly funded job in California, prevailing wage is not optional. It is a core compliance cost baked into labor, payroll, and your estimate.

Some projects also involve federal funding, which can add separate federal wage rules on top of state DIR requirements. Read the bid documents for which standards apply.

What counts as a public works project?

Public works generally means construction, alteration, demolition, or repair work paid for with public funds or performed for a public agency, subject to statutory definitions and exemptions.

Common examples:

• K-12 and university construction
• City and county facilities
• Water, sewer, and infrastructure contracts
• Many affordable housing projects with public funding triggers

When in doubt, check the awarding body’s prevailing wage determination in the bid package. Do not guess based on the job address alone.

How DIR prevailing wage rates work

DIR publishes general prevailing wage determinations by trade classification and county. Each determination includes:

• Basic hourly rate
• Fringe benefit amounts (or cash-in-lieu rules where allowed)
• Shift and overtime provisions tied to the determination

Rates update over time. Always use the determination referenced in your contract and verify current DIR publications before payroll.

Contractor obligations on prevailing wage jobs

Winning a public works contract in California typically requires:

• Paying at least the published rate for each worker classification
• Classifying workers correctly (no calling a carpenter a laborer to save rate)
• Submitting certified payroll records (CPRs) on schedule to the awarding body
• Posting prevailing wage rates on site as required
• Complying with apprenticeship requirements when applicable

DIR and awarding agencies audit payroll. Underpayment leads to back wages, penalties, and debarment risk.

Apprenticeship requirements

Many California public works contracts require use of registered apprentices through approved apprenticeship programs when a trade has an applicable program.

That affects staffing plans, ratios on site, and bid pricing. A low bid that assumes all journeymen may be impossible to perform legally.

Prevailing wage vs private commercial work

Many contractors use separate estimating templates for DIR jobs vs private work.

Payment timing on public jobs

Public projects also have progress payment and retainage rules under California public contract law. Slow payment on a public job may involve statutory release timelines different from private prompt payment rules.

Track billing cutoffs, retention release, and stored materials clauses in the public contract.

Practical tips

Price labor using the actual DIR rate for the county and classification, not your usual residential crew average.

Train office staff on certified payroll before you win the first municipal job.

Audit classifications monthly. A foreman misclassified on week one compounds across the whole job.

Keep subs compliant. Their prevailing wage failure becomes your problem on many public contracts.
