Prevailing Wage Requirements in California: Government Contract Rules
Last reviewed: June 2026
Quick Answer
California's prevailing wage law (Labor Code § 1720) requires contractors on public works projects to pay workers the prevailing wage rate for their trade and county, as determined by the Department of Industrial Relations. The prevailing wage includes base hourly rate plus fringe benefits. Coverage applies to all public works projects estimated to cost more than $1,000, including state, county, municipal, and district projects. Contractors must pay prevailing wages to all workers on covered projects, regardless of union status, and failure to do so can result in wage liens, penalties, and stop-work orders.
Key Facts
- •California requires contractors on public works projects to pay prevailing wages set by the Department of Industrial Relations.
- •Prevailing wage rates vary by trade, county, and project type; rates are updated regularly and posted online.
- •Violations can result in wage liens, stop-work orders, and penalties up to $200 per worker per day.
- •Davis-Bacon Act covers federally funded projects; California Prevailing Wage Act covers state and local public works.
- •All workers on covered projects must receive prevailing wages regardless of union membership or classification.
Federal Law: The Baseline
The Davis-Bacon Act, 42 U.S.C. § 3142, requires contractors on federally funded or assisted construction projects to pay workers the prevailing wage for their trade and geographic area. The U.S. Department of Labor (DOL) determines prevailing wage rates and enforces compliance. Coverage applies to federal construction projects exceeding $2,000 in value, including highways, schools, hospitals, and other public facilities funded with federal dollars.
The federal prevailing wage includes both base hourly wages and fringe benefits (health insurance, pension, vacation). The DOL Wage and Hour Division enforces Davis-Bacon requirements through investigations, wage audits, and litigation. Violators face liability for unpaid wages, liquidated damages, debarment from future federal contracts, and criminal penalties in egregious cases.
The Davis-Bacon Act applies nationwide and covers all construction trades. However, enforcement and wage-setting procedures vary by state. States like California layer additional state-level prevailing wage requirements on top of federal requirements, creating dual compliance obligations for contractors working on projects that receive both state and federal funding. The DOL maintains a prevailing wage database accessible to contractors and workers.
California Law: What's Different
California Labor Code § 1720 establishes a comprehensive prevailing wage law that is substantially stronger and broader than the federal Davis-Bacon Act. Under California law, prevailing wages apply to all public works projects estimated to cost more than $1,000, compared to the federal $2,000 threshold. This lower threshold captures significantly more projects under California's requirement.
The California Prevailing Wage Act (Labor Code §§ 1720–1861) defines public works broadly to include state, county, municipal, and district construction projects; maintenance and repair work on public property; and work performed on construction projects funded by public agencies. The definition is interpreted expansively by California courts and regulators. The Department of Industrial Relations (DIR) sets prevailing wage rates by trade and county, accounting for local labor conditions. These rates are updated regularly and posted on the DIR website.
California's law covers all workers on covered projects, including apprentices, helpers, and trainees. Unlike federal law, California prevailing wage rates typically exceed federal Davis-Bacon rates, creating higher labor costs for contractors. The prevailing wage includes both hourly wages and fringe benefits (health, pension, vacation, training funds). Contractors must pay prevailing wages even if the worker is non-union; wages cannot be reduced based on non-union status.
California also imposes strict enforcement mechanisms. Violations trigger administrative wage liens that attach to projects and retain 10% of contract value pending resolution. The state can issue stop-work orders, bar contractors from public works, and assess penalties of up to $200 per worker per day of violation. Workers and unions can also sue directly under Labor Code § 1741 for unpaid prevailing wages, treble damages, and attorney fees. The state's burden of proof is lower than federal enforcement—contractors must affirmatively demonstrate compliance.
Key Numbers & Thresholds
California prevailing wage applies to public works projects estimated to cost more than $1,000 (versus federal Davis-Bacon Act threshold of $2,000).
Prevailing wage rates vary by trade, county, and project type; rates are set and updated by the California Department of Industrial Relations and posted online.
Workers must be paid prevailing wages for all hours worked on covered projects, including travel time to and from the site.
Violations can result in administrative wage liens of up to 10% of contract value, stop-work orders, and daily penalties up to $200 per worker.
Contractors have 10 days from project completion to submit certified payroll records to the public agency; failure triggers presumption of non-compliance.
Statute of limitations for prevailing wage claims is three years under Labor Code § 1771(d), or four years if fraud is alleged.
Exceptions & Special Cases
Several exceptions and limitations apply to California's prevailing wage law, though these are narrowly construed by regulators and courts. The prevailing wage requirement does not apply to projects estimated to cost $1,000 or less; however, once a project exceeds $1,000, full prevailing wage obligations attach to all work.
Private construction projects are generally exempt, even if built on public land or for public benefit. However, projects funded or financed by public agencies—including tax increment financing, redevelopment agencies, or public agency grants—may trigger prevailing wage requirements despite private ownership. Courts have expanded this exception narrowly in favor of prevailing wage coverage.
Maintenance and repair work on public property is covered if performed by a contractor; routine maintenance performed by permanent public employees is typically exempt. Architects, engineers, and inspectors not directly performing construction work may fall outside coverage, though this boundary is fact-specific.
Subcontractors are not separately liable for prevailing wage violations by prime contractors; however, prime contractors remain liable for all subcontractor wages. This creates incentive for primes to audit subs, but subs can also sue primes directly.
Workers classified as independent contractors may be exempt if they genuinely control their work and are not employees under California's ABC test. However, misclassification is common and aggressively challenged by the Labor Commissioner and plaintiff attorneys.
Union-negotiated collective bargaining agreements that provide wages above prevailing wage rates do not create an exception to prevailing wage requirements; the higher amount is due. Prevailing wage is a floor, not a ceiling.
Small businesses and non-profits receive no exemption under California law, though they may be eligible for federal small business waivers under Davis-Bacon in limited contexts.
What to Do If Your Rights Are Violated
Step 1: Document Prevailing Wage Entitlement and Work Performed. Maintain detailed daily logs showing hours worked, job duties, trade classification, and dates. Request and retain the public agency's prevailing wage determination (PWD) notice at project start, which specifies applicable wage rates. Photograph or document the posted prevailing wage notice at the job site. Collect your employment agreement, offer letter, and any pay stubs showing base wages and fringe benefits. If fringe benefits are paid via third-party funds (pension, health plan), obtain documentation of contributions. Create a spreadsheet comparing your actual wages paid against the applicable prevailing wage rate using the DIR's rate tables.
Step 2: Internal Complaint Process and Dispute Resolution. Before filing externally, request a meeting with your contractor or employer in writing (email to project manager or payroll). Clearly state the dates worked, hours, and the prevailing wage rate you believe applies, citing the PWD. Ask for written explanation of any discrepancy. If the contractor refuses to meet or disputes your claim, request a written response within 10 business days. Document all communications. Some contractors will voluntarily pay if clearly mistaken; others will refuse, requiring external action. Internal resolution avoids litigation costs but delays remedies. Most prevailing wage cases proceed directly to regulatory or court filings without successful internal resolution.
Step 3: File a Wage Claim with the Labor Commissioner. California's Division of Labor Standards Enforcement (DLSE) accepts prevailing wage claims. File Form WC-1 (Employee's Claim for Wages) online at dir.ca.gov/dlse or in person at your county's DLSE office. No filing fee. Include the project name, location, contractor name, dates worked, hours per day, and the prevailing wage rate applicable. Attach supporting documents: pay stubs, time sheets, the PWD notice, and your wage calculations. The deadline is three years from the violation date (four years if fraud). Email or mail the completed claim to your regional DLSE office—contact information is on the DIR website. The Labor Commissioner will attempt informal settlement; if unsuccessful, a hearing before an administrative law judge is scheduled within 2–4 months.
Step 4: Investigation and Hearing Process. After filing, the DLSE sends notice to your employer. The employer typically responds within 20 days with payroll records and their position. The DLSE investigator may request additional documents from you and the employer. A Wage Claims Hearing before a referee is scheduled, typically 2–4 months after filing, and conducted via video or in person. You testify about hours, duties, and wages paid; the employer testifies and presents records. The referee issues a decision within 30 days, typically awarding unpaid prevailing wages, penalties, and potentially costs. The losing party can appeal to the Labor Commissioner within 10 days, then to superior court if unsatisfied.
Step 5: Consider Private Legal Action and Attorney Consultation. If the violation is substantial ($5,000+) or the employer disputes the claim, consult an employment attorney specializing in prevailing wage law immediately. California Labor Code § 1741 allows workers to sue contractors directly for unpaid prevailing wages in superior court, claiming treble damages (three times unpaid wages), penalties of $50–$200 per day, and attorney fees. This remedy is stronger than administrative claims and applies to individual and class actions. Attorneys typically work on contingency. If the DLSE ruling is unsatisfactory, an attorney can appeal or file a separate court action. Class action prevailing wage suits are common in California and can result in multi-million-dollar settlements. Contact a lawyer before the statute of limitations expires.

Frequently Asked Questions
How is the prevailing wage rate determined in California?
The California Department of Industrial Relations determines prevailing wage rates by trade and county through a survey-based methodology that analyzes wages paid on public works projects. The DIR publishes prevailing wage determinations (PWDs) for each county and trade, updated regularly and posted on the DIR website. Rates include both base hourly wages and fringe benefits (health insurance, pension, vacation, training funds). For your project, the applicable rate is the one in effect on the project start date, not the current date. Rates vary significantly by trade and county; for example, heavy equipment operators earn $60–$80/hour in some Bay Area counties, while laborers earn $45–$55/hour. Contractors are required to post the prevailing wage notice at the job site and provide copies to workers. You can verify the applicable rate by searching the DIR Prevailing Wage Database by county and trade classification. If a discrepancy exists between what you were paid and the posted rate, the posted rate controls.
Do I have to be a union member to receive prevailing wages?
No. California prevailing wage law applies to all workers on covered projects regardless of union membership or status. Many prevailing wage rates are based on union scale wages, but non-union workers are entitled to the same rate. Employers cannot reduce wages based on non-union status or avoid prevailing wage by hiring non-union labor. Some workers mistakenly believe prevailing wages apply only to union members, allowing employers to underpay non-union workers. This is illegal. The law explicitly states all workers on the project are entitled to prevailing wages for all trades and classifications in which they work. If you worked on a public works project and were paid less than the prevailing wage rate posted at the site, regardless of union membership, you were likely underpaid and can file a claim with the Labor Commissioner or sue the contractor directly.
What happens if a contractor doesn't pay prevailing wages?
California law imposes severe penalties for prevailing wage violations, making non-compliance costly and risky for contractors. The state can issue administrative wage liens that retain up to 10% of the contract value pending resolution of wage claims, effectively freezing contractor payment. Stop-work orders can be issued, halting the entire project until violations are remedied. Contractors face civil penalties of $50–$200 per worker per day of non-compliance, calculated from the first day of violation through full payment. Individual workers and unions can file administrative wage claims with the Labor Commissioner or sue directly in superior court under Labor Code § 1741, claiming unpaid prevailing wages plus treble damages (three times the amount owed) and attorney fees. Class actions are common and often result in multi-million-dollar settlements. Contractors can also be debarred from future public works contracts. Criminal penalties, including fines and imprisonment, apply in cases of intentional fraud. Most contractors violate prevailing wage laws through miscalculation or misclassification rather than intentional non-payment, but the penalties apply regardless of intent.
How long do I have to file a prevailing wage claim after leaving the job?
You have three years from the date of violation to file an administrative wage claim with the California Labor Commissioner (Form WC-1), as set by Labor Code § 1771(d). If fraud is involved, the statute of limitations extends to four years. The 'date of violation' is typically each pay period in which you were underpaid, meaning the three-year period runs from the most recent underpayment. For example, if you worked a project from January 2022 to March 2022 but were underpaid throughout, your three-year window opens from March 2022 and closes March 2025. If you file a claim in March 2025, you can recover back wages from March 2022 forward. However, if you wait until April 2025 to file, you lose claims from March 2022–March 2023. For maximum recovery, file as soon as you discover underpayment. If you plan to sue in superior court under Labor Code § 1741, the statute of limitations is four years, but interest and penalties may be reduced if you delay. Consult an attorney immediately to preserve all remedies.
Am I entitled to prevailing wages for travel time to and from the job site?
Yes. California prevailing wage law requires payment for all hours worked, including travel time from the employer's central facility or meeting point to the job site, and return travel. Travel time is compensable if it is a condition of employment or if the work site is remote or changes daily. However, commuting from your home to a permanent work site is not compensable. The DIR's prevailing wage determinations typically specify that travel time is compensable at the prevailing wage rate for the trade. If your contractor required you to report to a central facility and then traveled together to the job site (a common practice on large public works projects), all travel hours are prevailing wages. Many contractors improperly exclude or undercount travel time in payroll records. When documenting violations, include all travel hours worked and cite the DIR determination provisions on travel compensation. If you file a wage claim, include travel time in your calculation of hours owed.
