6.5 Public Works: Prevailing Wage, Apprenticeship & DIR Compliance

What Counts as "Public Works"

Public works is a defined legal term, not just any job performed for a government agency. Under Labor Code § 1720 and related sections, 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 -- city, county, state, school district, special district, or certain publicly subsidized private projects.

When any public money is involved, a C-20 contractor must assume DIR's public-works rules apply until confirmed otherwise, because the consequences of guessing wrong are steep.

DIR Contractor Registration

Before bidding, being listed as a subcontractor, or performing work on a covered public works project, a contractor and each subcontractor generally must hold an active Public Works Contractor Registration with the Department of Industrial Relations (DIR). The registration and annual renewal fee is $400 per year, covering the fiscal year running July 1 through June 30 regardless of the exact registration date; a lapsed registration carries a 90-day grace period to renew, with a late fee, before more serious consequences apply. Registration is separate from, and in addition to, CSLB licensure -- a valid C-20 license does not by itself authorize public works bidding.

Enforcement of the registration requirement, and of related certified-payroll submission requirements, was temporarily paused by DIR from June 22, 2024 through June 22, 2025, with enforcement resuming June 23, 2025. Contractors should always confirm current enforcement status directly on DIR's public works pages before assuming any past pause is still in effect, since these administrative pauses are time-limited.

Prevailing Wage Determinations

On covered public works, every worker must be paid not less than the prevailing wage rate for their craft or classification in the county where the work is performed. DIR issues general prevailing wage determinations twice a year, around February 22 and August 22, with each determination taking effect roughly 10 days after issuance. A determination lists the basic hourly rate, required fringe-benefit and employer payments, overtime and holiday rules, and any predetermined wage increases scheduled to take effect later during the contract.

Prevailing wage rates are frequently well above typical private residential rates for the same trade; underbidding a public job using private-market labor cost assumptions is one of the most common, and expensive, mistakes new public-works contractors make.

Apprenticeship Requirements

Labor Code § 1777.5 requires contractors on covered public works contracts over $30,000 to employ apprentices in an approximate ratio of one hour of apprentice work for every five hours of journeyman work performed in an apprenticeable craft, computed daily and counting only a journeyman's straight-time hours. Contractors must request apprentices through an approved apprenticeship program -- dispatched by the program, not hand-picked informally -- and, if the contractor employs no apprentices on a given contract, must generally make training-fund contributions instead. A verified statement of journeyman and apprentice hours is due to the awarding body and the apprenticeship program within 60 days after the contract concludes.

Certified Payroll Submission via DIR's eCPR System

Public works certified payroll (see the recordkeeping section earlier in this chapter for what a CPR must contain) is submitted to the Labor Commissioner through DIR's electronic Certified Payroll Reporting (eCPR) system, generally required for new construction, alteration, or repair contracts at or above $25,000 and maintenance contracts at or above $15,000. A report must be filed for every week a covered worker performs any work on the project, and a report is still typically required for weeks where no work was performed, to keep the compliance record continuous.

Penalties and Debarment

Underpaying prevailing wages exposes a contractor to statutory forfeitures under Labor Code § 1775 of up to $200 per calendar day per underpaid worker, with escalating statutory minimums: as little as $40 per day for a first, promptly corrected good-faith error, rising to at least $80 per day if the contractor has a prior violation within the past 3 years, and at least $120 per day for violations found to be willful. Beyond monetary forfeitures, Labor Code § 1777.1 authorizes debarment -- a period of 1 to 3 years during which a contractor found to have committed a willful violation, or repeated willful violations, may not bid on or be awarded any public works contract in California. DIR publishes a list of debarred contractors, and awarding bodies are expected to check it before awarding work.

Scenario

A C-20 contractor wins a $180,000 HVAC replacement contract at a public library. Before starting, the contractor confirms its DIR Public Works Contractor Registration is active, pulls the correct prevailing wage determination for HVAC and sheet-metal work in that county, staffs the job with the required apprentice-to-journeyman ratio by requesting an apprentice dispatch from the applicable joint apprenticeship program, and submits a certified payroll report through eCPR every week of the project -- including one slow week when the crew was rained out and performed no work.
