If you work on a California public works project, such as a school, road, park or government building paid for with public money, your employer generally must pay you the prevailing wage for your trade, including benefits and higher overtime rates. If you were paid less, you can file a complaint with the Labor Commissioner, ideally as soon as possible, because the agency must finish its investigation within 18 months after the project is completed. A lawsuit may still be possible within three years.
Key takeaways
- Prevailing wage applies to workers on most public works projects over $1,000, which includes many projects that are only partly paid for with public funds (Labor Code §§1720, 1771).
- The prevailing rate includes employer payments for health, pension, vacation and training. Those payments can’t be used to reduce your required hourly pay.
- You can request a certified copy of your own payroll records from the contractor (Labor Code §1776).
- Underpaid workers can recover the wage difference, and the contractor may also owe liquidated damages equal to the unpaid wages plus penalties of up to $200 per day per worker.
- File quickly: the Labor Commissioner must act within 18 months of project completion.

What prevailing wage is
Prevailing wage is a minimum pay rate for public works that is higher than the state minimum wage. The director of the Department of Industrial Relations (DIR) sets a rate for each craft and job classification in each area of the state, based on what most workers in that craft and area are paid, according to the Labor Commissioner’s public works brochure.
The rate has two parts: a basic hourly wage and “per diem” employer payments for things like health and welfare, pension, vacation, travel, subsistence and apprenticeship training (Labor Code §1773.1). An employer can generally get credit for benefit payments it actually makes into qualifying plans, but those credits don’t reduce the required straight-time or overtime hourly wage.
Public works also have their own overtime rules. Workers must get a higher overtime or premium rate for work over 8 hours in a weekday or on a Saturday, Sunday or holiday, with limited exceptions.
Which jobs are covered
Under Labor Code §1720, “public works” generally means construction, alteration, demolition, installation or repair work done under contract and paid for in whole or in part out of public funds. Some points workers often miss:
- “Construction” is broad. It includes preconstruction work such as inspection, site assessment and land surveying, and postconstruction work such as jobsite cleanup.
- Partial public funding counts. A private development can be a public work if the government pays money to the developer, sells it land below market value, or waives or reduces fees, rents, loans or other obligations.
- Subcontractors are covered too. The duty applies to every contractor and subcontractor on the job.
- Some maintenance work counts. The Labor Commissioner says some government maintenance contracts, such as landscaping or traffic signal work, can trigger public works laws.
Common prevailing wage violations
- Misclassification by trade. You do electrician or operator work but are paid as a laborer, which has a lower rate.
- Paying the base wage but not the benefits, or claiming benefit credits for plans that don’t exist or weren’t funded.
- Missing overtime and weekend premiums.
- Off-the-books hours, such as unrecorded early starts or cleanup time.
- Kickbacks, where workers are paid the right rate on paper and pressured to return part of it.
- Pay stubs that hide the project, making it hard to tell which hours were on the public job.
Some violations overlap with regular wage claims. See our pages on wage and hour violations and off-the-clock work.
An example
Here is a hypothetical. Luis works for a subcontractor on a public school modernization project. He spends most of his days running conduit and pulling wire, but his pay stubs list him as a general laborer, and he receives no benefit contributions. Luis requests a certified copy of his payroll records. They show 400 hours on the school project classified as labor. If the electrician rate for that county is higher, the gap for those 400 hours, including the benefit portion, may be owed, along with possible liquidated damages and penalties.
What you can recover
| Remedy | What it means | Law |
|---|---|---|
| Unpaid prevailing wages | The difference between the prevailing rate and what you were paid, for each day underpaid | Labor Code §1775 |
| Liquidated damages | An amount equal to wages still unpaid 60 days after a civil wage and penalty assessment is served, paid to the worker | Labor Code §1742.1 |
| Penalties against the contractor | Up to $200 per day per underpaid worker, with higher minimums for repeat or willful violations (paid to the public agency, not the worker) | Labor Code §1775 |
| Payroll record penalties | $100 per day per worker if the contractor doesn’t comply with a written records request within 10 days (paid to the state or public agency, not the worker) | Labor Code §1776 |
| Debarment | Contractors found to have violated the law with intent to defraud, or willfully more than once in three years, can be barred from public works for up to three years | Labor Code §1777.1 |
If you’ve quit or been fired and your final wages were short, waiting-time penalties under Labor Code §203 may also apply.
How to file a prevailing wage complaint
- Gather what you have. Pay stubs, your hours, the project name and address, your employer, the general contractor and the public agency paying for the project.
- Request your certified payroll. You or your authorized representative can ask the contractor for a certified copy of your own payroll records. These records must show your classification and daily hours and are signed under penalty of perjury.
- File the Worker Complaint Form (PW1). The Labor Commissioner’s public works complaint page explains how to file by email or mail. Complaints for Imperial, Los Angeles, Orange, Riverside, San Bernardino, San Diego, Santa Barbara and Ventura counties go to the Long Beach office, and all other counties go to Sacramento.
- Cooperate with the investigation. The Public Works Unit gathers information from the employer and the public agency and interviews witnesses. If it finds violations, it issues a civil wage and penalty assessment, and the agency paying for the project can be told to withhold payments.
- Watch the clock. The Labor Commissioner must complete its investigation and issue assessments within 18 months after the project is completed. After that, a lawsuit in superior court may still be possible if filed within three years.
You don’t need a Social Security number, photo ID or a lawyer to file, and the Labor Commissioner provides interpreters. You may file a complaint regardless of your immigration status.
Protection from retaliation
Your employer can’t fire, demote, suspend or cut your hours because you complained about pay, answered an investigator’s questions or filed a claim. Labor Code §98.6 protects wage complaints, and Labor Code §1102.5 protects reports of suspected legal violations to a government agency or a supervisor. Retaliation complaints to the Labor Commissioner generally must be filed within one year.
Frequently asked questions
How do I know if my project is a public work?
Look for a government owner or funding source: a school district, city, county, state agency or transit authority. Ask your employer or the general contractor, check signs posted at the jobsite, or ask the public agency directly.
Where do I find the prevailing wage rate for my trade?
DIR’s director sets the rates by craft, classification and county, and DIR publishes them. The rate that applies is generally the one in effect for your project, so note the project name and the agency that awarded it.
Can my employer pay part of the prevailing wage as benefits?
Yes, if the employer actually pays into qualifying benefit plans. Those payments count toward the total prevailing wage package, but they can’t lower your required hourly wage for straight time or overtime.
What if the project finished more than 18 months ago?
The Labor Commissioner generally can no longer act, but the Labor Commissioner says a lawsuit in superior court may be possible within three years for prevailing wage, minimum wage, overtime and similar violations.
Do I need to be a union member to get prevailing wage?
No. Prevailing wage applies to covered work on public projects whether or not you belong to a union.
