California Labor Code Section 1771 requires that every worker on a public works contract worth more than $1,000 be paid the general prevailing rate of per diem wages for their craft and the county where the work is done.1California Legislative Information. California Code Labor Code 1771 – Payment of General Prevailing Rate The rule reaches construction, alteration, demolition, installation, and repair work funded in whole or in part by public money, and it binds every contractor and subcontractor on the job. One important carve-out: Section 1771 applies only to work performed under contract, so a city or county using its own employees to do the work is not covered.
What Counts as a Public Works Project
Labor Code Section 1720 defines public works as construction, alteration, demolition, installation, or repair work done under contract and paid for with public funds. The reach is wider than most people expect. It extends backward into the preconstruction phase to cover site assessment, land surveying, and inspection, and forward into postconstruction cleanup. Even assembling modular office systems counts as installation under the statute.2California Legislative Information. California Code LAB 1720 – Public Works
Two dollar thresholds matter. Section 1771 itself kicks in above $1,000 in contract value. Separately, the contractor registration requirement discussed below applies to construction-type public works over $25,000 and to maintenance work over $15,000.3California Legislative Information. California Code Labor Code 1771.1
How the Prevailing Wage Is Set
The prevailing wage is a basic hourly rate plus employer payments for fringe benefits such as health insurance and pension contributions. The Director of the Department of Industrial Relations publishes general prevailing wage determinations twice a year, on February 22 and August 22, with separate rates for each craft classification in each county.4Department of Industrial Relations. Frequently Asked Questions – Prevailing Wage
Once a determination takes effect, the rate that applies on the date a project is advertised for bids generally locks in for the life of that contract. Some determinations carry a double-asterisk notation, meaning a predetermined rate increase will take effect on a specified future date; contractors working past that date must pay the higher rate.5Cornell Law Institute. California Code of Regulations Title 8 Section 16204 – Effective Dates of Determination Checking for those asterisks before locking in a bid price can save a project budget.
Contractor Registration With DIR
Before a contractor or subcontractor can bid on, be listed in a bid proposal for, or perform any public works project, they must be registered with the Department of Industrial Relations.3California Legislative Information. California Code Labor Code 1771.1 The initial registration fee is $400, and renewals are due by July 1 each year. The DIR Director can adjust renewal fees to cover program costs.6California Legislative Information. California Code Labor Code LAB 1725.5
Awarding bodies — the cities, counties, school districts, and agencies issuing contracts — must include registration as a bid requirement and cannot accept a bid or enter a contract without proof of current registration. A narrow exception allows an unregistered contractor to submit a bid under certain Business and Professions Code or Public Contract Code provisions, but registration must be in place by the time the contract is awarded.
Certified Payroll and Job Site Duties
Certified payroll records are the backbone of enforcement. Every contractor and subcontractor must keep records showing each worker’s name, address, Social Security number, job classification, daily and weekly hours, and actual wages paid. Each record must include a declaration under penalty of perjury that the information is accurate and that the employer has met the prevailing wage requirements.7California Legislative Information. California Code Labor Code LAB 1776
Records must be available for inspection at the contractor’s principal office. Workers and their representatives can request their own payroll records directly. The awarding body and the Division of Labor Standards Enforcement can request everything at any time. Members of the public can also request inspection, though they must route the request through the awarding body or DLSE.
When a request comes in, the contractor has 10 days to produce the records. Missing that deadline carries a penalty of $100 per calendar day, per worker, for each day the records remain unproduced. Failing to produce records within 30 days of a written notice from the Labor Commissioner can also trigger debarment.8California Legislative Information. California Code Labor Code LAB 1777.1
The prime contractor must also post job site notices informing workers that the project is subject to prevailing wage requirements and identifying the applicable rates.
Apprenticeship Ratio and Training Fund
Public works contractors must employ one hour of apprentice work for every five hours performed by a journeyman in each applicable craft.9Department of Industrial Relations. Apprentices on Public Work Projects Summary of Requirements The 1-to-5 ratio is measured cumulatively by the end of the project, not day by day.
Contractors must also make training fund contributions at the rate published in the prevailing wage determination for each craft. Those who already contribute to a registered apprenticeship program get full credit for those contributions. Contractors who do not participate in a program must send their training fund payments to the DIR’s California Apprenticeship Council by the 15th of each month for work performed the prior month.
Penalties for Underpayment and Noncompliance
Under Labor Code Section 1775, a contractor or subcontractor that pays less than the prevailing wage forfeits up to $200 per calendar day, per worker, for each day the worker was underpaid. When the Labor Commissioner finds the violation was willful, the minimum penalty is $120 per day per worker. The contractor also owes the full amount of the underpaid wages to the affected workers.10California Legislative Information. California Code Labor Code 1775
Awarding bodies can withhold contract payments when payroll records are delinquent or inadequate, or when an investigation confirms underpayment. Those funds stay frozen pending a final order or the end of the review period.
Debarment
The most severe consequence is debarment: losing the right to bid on or perform any public works project in California. The Labor Commissioner can impose it in several circumstances.8California Legislative Information. California Code Labor Code LAB 1777.1
- A violation of prevailing wage law committed with intent to defraud brings debarment of one to three years.
- Two or more separate willful violations within three years can bring debarment of up to three years.
- Failing to produce certified payroll records within 30 days of a written notice from the Labor Commissioner can bring one to three years of debarment.
- A knowing serious violation of the apprenticeship requirements can bring debarment of up to one year for a first offense and up to three years for subsequent offenses.
Debarment extends to any firm, corporation, partnership, or association in which the debarred contractor has an interest, so a new corporate name does not reset the clock.
Civil Wage and Penalty Assessment
When the Labor Commissioner finds a violation, the office issues a civil wage and penalty assessment stating the back wages, penalties, and forfeitures owed. The assessment must be served within 18 months after either a valid notice of completion is filed with the county recorder or the awarding body accepts the completed project, whichever happens later.11California Legislative Information. California Code Labor Code LAB 1741 Any surety on a payment bond for the project is also liable for the assessed amounts.
Filing a Prevailing Wage Complaint
A worker who believes they were underpaid on a public works project can file a complaint with the Division of Labor Standards Enforcement using the Worker Complaint Form (PW-1). The fastest route is email through the DLSE’s dedicated public works address. Hard copies can be mailed to the Long Beach office, which handles Los Angeles, Orange, San Diego, Riverside, San Bernardino, Imperial, Santa Barbara, and Ventura counties, or to the Sacramento office for the rest of the state.12Department of Industrial Relations. How to File a Public Works Complaint
Before filing, gather pay stubs, time records, the job classification you performed, and the dates and location of the work. File promptly. Because the Labor Commissioner’s assessment must be served within 18 months of project completion or acceptance, delays that push an investigation past that window can make enforcement much harder.
When Federal Davis-Bacon Rules Also Apply
Projects that receive federal funds along with state money may trigger both California’s prevailing wage law and the federal Davis-Bacon Act. When both apply, the contractor must pay whichever rate is higher for each craft classification. California rates tend to be among the highest in the country, but that is not uniformly true for every classification in every county, so comparing both schedules before bidding matters.
Davis-Bacon defines the prevailing wage similarly, as a basic hourly rate combined with fringe benefits. Qualifying fringe benefits under federal law include health insurance, pension contributions, vacation and holiday pay, life insurance, apprenticeship training costs, and supplemental unemployment benefits.13Department of Energy. Ensuring Prevailing Wages: A Closer Look at the Davis-Bacon Act Federal projects require weekly certified payroll submissions with a signed Statement of Compliance, rather than California’s on-request system.14U.S. Department of Labor. Instructions For Completing Davis-Bacon and Related Acts Weekly Certified Payroll Form WH-347 Where both regimes apply, the safe course is to meet whichever standard is stricter on each compliance point.
