Prevailing Wage Compliance: A Subcontractor's Checklist

In California, every contractor and subcontractor performing public works must pay workers no less than the general prevailing rate of per diem wages as determined by the DIR Director. This is not optional. Labor Code §1771 makes prevailing wage mandatory on all public works projects over $1,000 ($15,000 for new construction, $25,000 for alteration/repair/maintenance). Violations carry real consequences: Labor Code §1775 imposes penalties of up to $200 per day per worker for each violation, plus back-pay obligations. Willful violations can result in debarment from public works for up to three years.

For subcontractors, the compliance burden falls squarely on you. The GC may be the prime contractor, but each sub is independently responsible for paying correct rates, maintaining certified payroll records, and ensuring apprenticeship compliance. Classification mistakes, sloppy record-keeping, or unfamiliarity with the applicable wage determination are the most common paths to a violation.

DIR Registration: The Threshold Requirement

Before anything else, confirm that your company and every subcontractor below you is registered with the California Department of Industrial Relations (DIR). Under Labor Code §1725.5, no contractor or subcontractor may bid on, be listed on, or perform work on a public works project without active DIR registration. On Caltrans projects, Section 7-1.02K makes this explicit: unregistered contractors cannot be listed in a bid and cannot perform work on the project. The penalty for non-compliance is severe: an unregistered sub performing public works is subject to contract termination and financial penalties.

Check registration status at the DIR website before every bid. Registration must be current at the time of bid submission and maintained continuously through project completion.

Know the Applicable Wage Determination

Before you bid, identify which wage determination applies to the project. In California, prevailing wage rates are published by the DIR and are county-specific.

Key items to verify: - The correct geographic area (county where the work is performed). - The correct type of construction (building, heavy, highway, residential). - The specific craft classifications that apply to your workers. - Fringe benefit requirements: prevailing wage includes both the base hourly rate and required employer payments (health and welfare, pension, vacation, training fund contributions).

On Caltrans projects, Section 7-1.07 requires posting the prevailing wage determinations at the job site and maintaining certified payroll records per Labor Code §1776. On local agency projects using the Greenbook, Section 7-2.2 requires payment of not less than prevailing rates per Labor Code §1774, with the higher of state or federal rates applying on federally funded projects.

Wage determinations are locked in at bid time. If rates change after award, the original determination typically applies. Read the contract carefully for escalation provisions.

Classification Is Where Most Errors Occur

The most common prevailing wage violation is misclassifying workers. A journeyman electrician performing electrician's work must be paid the electrician's prevailing rate, even if they are carried as a general laborer on your payroll. Similarly, a laborer who operates equipment must be paid the equipment operator's rate for those hours.

Labor Code §1777.5 establishes apprenticeship requirements: contractors must employ registered apprentices at the correct ratio for each craft and pay them the approved percentage of the journeyman rate. Failure to maintain apprenticeship ratios is a separate violation that carries its own penalties.

Maintain clear records of what each worker does on the project, hour by hour if necessary. If a worker performs duties in multiple classifications during a single day, they must be paid the higher rate for the hours spent in the higher classification. When in doubt about a classification, request a ruling from the contracting agency before work begins.

The Compliance Checklist

Before each pay period, verify:

- All workers are paid at or above the applicable prevailing wage rate for their classification. - Fringe benefits (health and welfare, pension, vacation, training) are provided at the required rates or the cash equivalent is included in wages. - Certified payroll reports are prepared accurately per Labor Code §1776 and submitted on time. Payroll records must include worker name, address, social security number, classification, hours worked each day, and actual per diem wages paid. - Apprentices are registered with an approved program and paid the correct percentage of the journeyman rate per Labor Code §1777.5. - Overtime (over 8 hours per day or 40 hours per week) is calculated correctly on the prevailing wage base. - DIR registration is current for your company and all lower-tier subcontractors. - Prevailing wage rate postings are visible at the job site. - Payroll records are retained for at least 3 years.

The Bottom Line

Prevailing wage compliance is a documentation exercise. The penalties under Labor Code §1775 are $200 per day per worker, per violation. On a crew of 10 over a two-week period, a classification error can generate $28,000 in penalties before you even count the back-pay obligation. Add potential debarment from public works contracting, and the cost of non-compliance dwarfs the cost of getting it right.

The subcontractors who stay out of trouble treat prevailing wage as a system, not a checkbox. They verify classifications before work starts, maintain certified payroll as a weekly discipline, keep DIR registration current, and train their field supervisors to recognize when a worker's duties cross classification lines. Compliance is not complicated. It is just relentless.
