California’s prevailing wage law requires anyone doing construction, alteration, demolition, installation, or repair work on a public works project over $1,000 to pay each worker at least the hourly rate the Department of Industrial Relations (DIR) has set for that trade in that county, including fringe benefits. Rates are published twice a year by craft and county. Contractors and subcontractors must register with DIR before bidding or working, keep certified payroll records, and employ apprentices alongside journeymen. Workers who are underpaid can file a complaint with the Division of Labor Standards Enforcement using form PW-1.
Which Projects Are Covered
Labor Code Section 1720 defines public works broadly. If public dollars pay for construction, demolition, installation, or repair work performed under contract, prevailing wage applies.1California Legislative Information. California Code Labor Code 1720 The definition reaches further than most people expect. Land surveying, site assessment, jobsite cleanup, carpet installation in public buildings, and assembly of modular office systems all count.2California Legislative Information. California Code LAB 1720
The dollar trigger is $1,000 for the total project cost, not just the labor portion.3U.S. Department of Labor. Dollar Threshold Amount for Contract Coverage An awarding body that operates an approved labor compliance program can raise the threshold to $25,000 for new construction or $15,000 for alteration, demolition, repair, or maintenance, but the higher figure is not automatic and requires active enforcement by the awarding body.4California Legislative Information. California Code Labor Code LAB 1771.5 Assume the $1,000 baseline until you confirm otherwise.
Registering With DIR
Since 2015, every contractor and subcontractor must be registered with DIR before bidding on or performing any public works project.5Department of Industrial Relations. SB 854 Important Information for Awarding Bodies Awarding bodies cannot legally accept a bid from an unregistered contractor, and an unregistered contractor cannot work on the jobsite. The requirement flows down to every tier of subcontractor, which catches many subs off guard.
Registration costs $400 for one year, $800 for two, or $1,200 for three, running with the state fiscal year (July 1 through June 30).6Department of Industrial Relations. Contractor Registration To qualify, a contractor must carry current workers’ compensation coverage, hold the appropriate state license, and certify it has no delinquent wage liabilities or outstanding debarment orders.7California Legislative Information. California Code Labor Code LAB 1725.5 A lapsed registration blocks you from bidding or working until you renew.
How the Rate Is Set
The DIR Director publishes prevailing wage rates for each craft and county, drawing primarily from collective bargaining agreements and local wage surveys.8Department of Industrial Relations. Frequently Asked Questions – Prevailing Wage Workers are grouped by classification (carpenter, electrician, operating engineer, laborer, and so on), and each classification carries its own rate. General determinations come out twice a year, on February 22 and August 22.
The rate that applies to a contract is the one in effect on the date the project was advertised for bids. If a worker performs tasks across two classifications during a shift, the contractor pays the rate for each classification based on the actual time spent on that work. Slotting a higher-skilled worker into a cheaper classification is one of the most common ways contractors run into enforcement.
What the Prevailing Wage Includes
The prevailing wage is a total compensation figure, not a single hourly number. It combines the basic hourly cash rate with employer payments toward fringe benefits. Section 1773.1 lists the qualifying categories: health and welfare, pension, vacation, travel, subsistence, and apprenticeship training contributions, along with certain payments made under collective bargaining agreements.9California Legislative Information. California Code LAB 1773.1
Employer benefit payments count as a credit against the total obligation. If your health and pension contributions are worth $15 an hour, that $15 offsets the fringe portion of the required total. If you provide no benefits at all, you still owe the full amount, and the fringe portion has to be paid to the worker as additional cash wages. Fringe credits cannot reduce the straight-time or overtime hourly rate below the prevailing figure. They only offset the employer’s benefit-side payment.
Overtime
Public works projects carry their own overtime rule. Work beyond eight hours in a calendar day, or beyond 40 hours in a workweek, must be paid at no less than one and a half times the basic prevailing rate.10Department of Industrial Relations. California Prevailing Wage Laws The multiplier applies to the prevailing wage figure, not to whatever the contractor otherwise pays. Awarding bodies obtain the overtime and holiday rates from the Director along with the standard rates, so the premium is not left to interpretation.
Apprenticeship Ratio
Public works contractors also have to employ apprentices. The baseline is one hour of apprentice work for every five hours of journeyman work in each applicable trade.11California Legislative Information. California Code Labor Code LAB 1777.5 The ratio applies on any day a journeyman works on the project and is calculated from straight-time hours only.
Exemptions exist. A contractor whose statewide apprentice employment already meets the 1-to-5 ratio on an annual average can apply for a certificate exempting it from the project-by-project rule. Apprenticeship programs can also grant exemptions when local unemployment in the trade exceeds 15 percent, when the area already has more apprentices in training than the ratio requires, or when placing an apprentice on the work would create a safety hazard. Failure to meet the requirement carries a $200-per-day civil penalty for each worker employed in violation.10Department of Industrial Relations. California Prevailing Wage Laws
Certified Payroll Records
Every contractor and subcontractor must keep certified payroll records showing each worker’s name, address, Social Security number, job classification, daily and weekly hours (straight time and overtime), and actual wages paid.12California Legislative Information. California Code Labor Code 1776 Each record includes a signed declaration under penalty of perjury that the information is accurate and that the employer complied with prevailing wage and overtime requirements.
Workers can request a certified copy of their own payroll records. The awarding body and the Division of Labor Standards Enforcement (DLSE) can request records at any time. Members of the public can request records through the awarding body or DLSE. Once a written request is received, the contractor has 10 days to comply. Miss that deadline and the penalty is $100 per calendar day, per worker, until the records are produced. DLSE can also direct the awarding body to withhold progress payments until the contractor complies.
Filing a Complaint if You Were Underpaid
Workers who believe they were underpaid on a public works project file a complaint using the PW-1 form, formally titled “Public Works — Worker Complaint.”13Department of Industrial Relations. Public Works Worker Complaint Form PW-1 This is a different form from the general DLSE wage claim used for private employment. The general claim form specifically directs public works claimants to use the PW-1 instead.14Department of Industrial Relations. Initial Report or Claim
Before you file, gather the official project name, the general contractor and any subcontractors involved, your specific dates and hours worked, pay stubs, and the DIR wage determination for your classification and county. The project number from public bid documents helps. Compare your pay against the determination and lay the discrepancy out clearly on the form. You can submit by mail or through a local district office. Keep a copy and use certified mail if sending paper, so you have proof of the submission date. A deputy labor commissioner reviews the complaint against the contractor’s certified payroll records and may contact you for more information or set a settlement conference with the employer.
Penalties, Damages, and the 18-Month Window
When the Labor Commissioner confirms a violation, the office issues a Civil Wage and Penalty Assessment to the contractor, the subcontractor, or both.15California Legislative Information. California Code Labor Code LAB 1741 The assessment identifies the violation, the unpaid wages, applicable penalties, and forfeitures. Interest accrues on unpaid wages from the date they were originally due.
The assessment must be served within 18 months after the filing of a notice of completion in the county recorder’s office, or within 18 months after the awarding body accepts the completed work, whichever comes later.10Department of Industrial Relations. California Prevailing Wage Laws If you were underpaid and wait too long to complain, that window can close.
If the contractor does not pay within 60 days after being served with the assessment, liquidated damages kick in. The damages equal the unpaid wages still outstanding, so a $50,000 back-wage figure that goes unpaid for 60 days can grow to $100,000. A contractor can avoid liquidated damages only by showing substantial grounds for believing the assessment was wrong, which requires both a reasonable subjective belief and an objective legal basis, and the error must have substantially reduced the wages owed.16Department of Industrial Relations. California Code of Regulations Title 8 Section 17251 – Liquidated Damages That bar is high.
When Federal Rules Also Apply
If the project receives federal construction funding, the federal Davis-Bacon Act adds a second set of wage requirements to any contract over $2,000.17U.S. Department of Labor. Davis-Bacon and Related Acts On dual-funded projects, contractors must comply with both the California prevailing rate and the Davis-Bacon rate for each classification, paying whichever is higher.
Federal law also imposes its own overtime rule through the Contract Work Hours and Safety Standards Act, requiring time and a half for hours over 40 per week on prime contracts exceeding $100,000. California’s daily overtime trigger at eight hours is more protective than the federal weekly trigger, so on most dual-funded projects the California rule controls. The two enforcement systems operate independently, and a contractor on a dual-funded project can face separate investigations and penalties from DLSE and the U.S. Department of Labor, including potential debarment from federal contracts.
