Public Works
When the customer paying for a construction project is a government body, an entirely separate layer of labor and payment law applies on top of the ordinary contractor rules. This chapter explains how to recognize a public works job and the prevailing-wage, registration, payroll, bonding, and insurance duties that come with it.

What Counts as a Public Works Project
When prevailing wage attaches
The rule
Prevailing wage is owed on every public works contract over $1,000 — work paid for in whole or in part out of public funds — and only projects of $1,000 or less sit outside the rule.
When it applies — and when it does not
- What makes a job public works is where the money comes from, not who owns the land: construction, alteration, demolition, installation, or repair work done under contract and paid for in whole or in part out of public funds.
- The line is drawn at over $1,000. A project of exactly $1,000, or less, falls inside the statutory exemption.
- An awarding body that has adopted a DIR-approved labor compliance program may choose not to require prevailing wage on projects of $25,000 or less for construction work, or $15,000 or less for alteration, demolition, repair, or maintenance work. Without that program, the $1,000 line applies.
- Section 1771 applies to work performed under contract; it does not reach work a public agency carries out with its own forces.
Worked contrast
| General prevailing-wage threshold (Lab. Code §1771) | over $1,000 |
| Labor-compliance-program exemption, construction work (§1771.5) | $25,000 or less |
| Labor-compliance-program exemption, alteration, demolition, repair, maintenance (§1771.5) | $15,000 or less |
| DIR registration and certified payroll exemption (§1725.5(f)) | $25,000 or less construction; $15,000 or less maintenance |
Common mix-ups
- The $25,000 and $15,000 figures are not the general prevailing-wage threshold, but they are not idle either: they cap the conditional §1771.5(a) election an approved awarding body may make, and the same two figures separately mark the cutoff for DIR registration under §1771.1(n) and §1725.5(f).
- Payment bonds also turn on $25,000 (Civ. Code §9550). That is a bonding rule, not a wage rule.
- "$1,000 or more" and "over $1,000" are not the same sentence; the statute exempts projects of $1,000 or less.

Prevailing Wage — How Rates Are Set
Which determination, and what is inside the rate
The rule
The rate you owe is the DIR determination for that craft and county in force when the work is performed, and it is the basic hourly rate plus the employer fringe payments, not the cash rate alone.
When it applies — and when it does not
- General determinations are issued twice a year, on February 22 and August 22, and go into effect ten days later.
- Employer payments for health and welfare, pension, vacation, travel, subsistence, and apprenticeship or other training are a credit against the obligation. Make no such payments and there is no credit, so the whole determination has to reach the worker in cash.
- The awarding body must cause a copy of the director's determination to be posted at each job site.
Worked contrast
| General determinations issued | twice a year, February 22 and August 22 |
| When a determination takes effect | ten days after it is issued |
| Which determination governs | the one in force for the craft and locality when the work is performed |
| What the rate is made of | basic hourly rate plus employer fringe payments |
Common mix-ups
- The determination is per craft and per county, not one statewide number.
- Paying the basic hourly rate in cash is not the whole obligation; the fringe amount is part of the rate.
- The DIR sets the rate; the awarding body is the one that has it posted at the job site.

DIR Contractor Registration
DIR registration is not your licence
The rule
A CSLB licence is not enough for public works: you must also hold a current DIR public works registration, renewed on the annual fiscal-year cycle, to bid, to be listed in a bid, and to perform the work.
When it applies — and when it does not
- The fee is $400 for one fiscal year, and you may pay in annual increments up to three years at a time ($800 for two years, $1,200 for three). That prepays the renewals; it is not a one-off lifetime registration.
- Subcontractors register too: registration is what makes a contractor qualified to be listed in a bid proposal under Public Contract Code §4104.
- Registration is not required for work on a public works project of $25,000 or less for construction, alteration, demolition, installation, or repair, or of $15,000 or less for maintenance.
- The director may set and adjust the annual fee up to $800 by publishing it on the department's website, so read the current figure rather than memorising one.
Worked contrast
| CSLB licence | issued and renewed through the CSLB; it is what lets you contract at all |
| DIR public works registration | renewed on the annual fiscal-year cycle; it is what lets you bid and work public works |
| Registration fee | $400 for one fiscal year, $800 for two, $1,200 for three |
| Small-project exemption (§1725.5(f)) | $25,000 or less construction; $15,000 or less maintenance |
Common mix-ups
- Registration runs per contractor per year, not per project.
- The DIR registration and the CSLB licence run on separate clocks; renewing one does not renew the other.
- Buying three years at once is prepaying three annual increments, not registering once and for all.

Certified Payroll & Apprenticeship
The 1:5 apprentice ratio
The rule
On a public works contract of $30,000 or more you must employ apprentices for at least one hour of apprentice work for every five hours of journeyman work in that craft.
When it applies — and when it does not
- The ratio is measured across the contract, not shift by shift: the computed apprentice hours must be worked before the end of the contract.
- Contracts of a general contractor, or of a specialty contractor not bidding through a general or prime contractor, that involve less than $30,000 are outside the section.
- Apprentices come from a state-approved program; ask for them with a DAS 142 dispatch request at least 72 hours (excluding Saturdays, Sundays and holidays) before you need them.
Worked contrast
journeyman hours ÷ 5 = the minimum apprentice hours
| The ratio | 1 hour of apprentice work per 5 hours of journeyman work |
| 200 journeyman hours | at least 40 apprentice hours |
| Threshold for the apprenticeship duty | contracts of $30,000 or more |
| How the ratio is measured | cumulatively over the contract, met before it ends |
Common mix-ups
- 1:5 is not one apprentice for every five journeymen on the crew. It counts hours of work, not heads.
- Falling short on a single day is not by itself a violation; the count runs over the whole contract.
Source: Labor Code §1777.5 · Labor Code §1777.5 (contract threshold) · 8 CCR §230.1 · 8 CCR §230.1 (dispatch request)
Telling the committee, and what a knowing violation costs
The rule
Before you start work you must send contract award information (the DAS 140) to each applicable apprenticeship committee within ten days of executing the contract, and a knowing second violation of the apprenticeship rules can keep you off public works for up to three years.
When it applies — and when it does not
- The ten days run from execution of the prime contract or subcontract, and in no event later than the first day you have workers employed on the public work.
- DAS 140 is the award notice, one per applicable craft. DAS 142 is the later request to dispatch apprentices, at least 72 hours before you need them.
- The project notice to the DIR is the awarding body's filing, within 30 days of the award and no later than the first day a contractor has workers on the public work. It is not the contractor's form.
- The money penalty and the bidding ban live in two different sections: civil penalties in §1777.7, ineligibility to bid in §1777.1.
Worked contrast
| DAS 140 contract award information | within 10 days of executing the contract, and before workers are on site |
| DAS 142 dispatch request | at least 72 hours before apprentices are needed |
| Civil penalty for a knowing violation (§1777.7) | up to $100 per day; up to $300 per day for a repeat within three years |
| Ineligibility to bid (§1777.1(d)(1)) | up to 1 year for a first violation; up to 3 years for a second or subsequent |
Common mix-ups
- Section 1777.7 no longer carries the bidding ban. Since it was repealed and re-added in 2014 it sets civil penalties, and the up-to-three-year ineligibility sits in §1777.1(d)(1).
- DAS 140 and DAS 142 are different filings on different clocks, and the DIR project notice belongs to the awarding body.

Where the certified payroll actually goes
The rule
On a DIR-monitored public works job the payroll records for every worker go to the Labor Commissioner in electronic form at least once every 30 days, not only to the awarding body.
When it applies — and when it does not
- The record shows each worker's name, address, social security number, work classification, straight time and overtime hours worked each day and week, and the actual per diem wages paid, and it carries a written declaration under penalty of perjury that the information is true and correct.
- Monthly means at least once every 30 days while work is being performed on the project, and once more within 30 days after the final day of work.
- The format is electronic, in the manner the Labor Commissioner prescribes on the department's internet website.
- Separately from that upload, a certified copy must be made available for inspection or furnished on request to the employee or the employee's representative, to the awarding body, and to the Division of Labor Standards Enforcement.
Worked contrast
| Where the records go (§1771.4) | to the Labor Commissioner, electronically, in the manner prescribed on the department's website |
| How often (§1771.4) | at least every 30 days while work continues, and within 30 days of the last day worked |
| Failing to upload (§1771.4) | $100 per day, not to exceed $5,000 per project, and not levied until 14 days after the deadline |
| Failing to produce records on request (§1776(h)) | $100 for each calendar day, for each worker, until strict compliance |
Common mix-ups
- Sending the records to the awarding body is not the whole duty. On a monitored job they also go to the Labor Commissioner.
- Two different $100 penalties. The §1771.4 one runs per day and stops at $5,000 for the project; the §1776(h) one runs per day for each worker until the records are produced.
- Payroll compliance runs to the Labor Commissioner. Neither the county recorder nor the local building official is a recipient of certified payroll.

Public Works Bonding
Which bond does what
The rule
On a public works contract in excess of $25,000 the direct contractor must give a payment bond before work starts, and the bond has to be executed by an admitted surety insurer.
When it applies — and when it does not
- The payment bond exists because public property cannot be liened; it stands behind the workers, subcontractors and suppliers who have no lien to record.
- A bid bond, or other bidder's security, is submitted with the bid and guarantees the successful bidder will sign the contract and furnish the required bonds.
- A performance bond is executed by the party awarded the contract for the faithful performance of the contract; it answers to the awarding body, not to the suppliers.
- Admitted surety insurer means a surety company licensed and authorised to transact that business in California. A bank, an insurance agent, or the awarding agency itself cannot stand in for it.
Worked contrast
| Payment bond | required over $25,000; guarantees workers, subcontractors and suppliers are paid |
| Performance bond | guarantees faithful performance of the contract |
| Bid bond | guarantees the successful bidder executes the contract |
| Who may issue it | an admitted surety insurer |
Common mix-ups
- The payment bond and the performance bond are both furnished by the prime, but they protect different people.
- The $25,000 figure belongs to the payment bond, not to the prevailing-wage threshold.

Stop Payment Notices on Public Works
The stop payment notice replaces the lien
The rule
You cannot lien public property, so an unpaid claimant serves a stop payment notice on the public entity to make it hold back project funds, and once a notice of completion, acceptance or cessation is recorded there are 30 days to do it.
When it applies — and when it does not
- If no notice of completion, acceptance or cessation is recorded, the window is 90 days after cessation or completion.
- On receipt, the public entity must withhold from the direct contractor funds sufficient to pay the claim stated in the notice, plus its reasonable cost of any litigation.
- Rights against the construction fund on a public works contract are governed exclusively by this chapter; no other legal or equitable theory reaches that fund.
Worked contrast
| Notice of completion, acceptance or cessation recorded | 30 days to give the stop payment notice |
| No such notice recorded | 90 days after cessation or completion |
| Action on the payment bond (Civ. Code §9558) | not later than six months after the stop-notice period closes |
| Mechanics lien on the agency's land | not available |
Common mix-ups
- Civil Code §9558 is the deadline for suing on the payment bond. The 30-day and 90-day stop-notice windows are §9356.
- Recording a notice of completion shortens the window from 90 days to 30. It never extends it.

Insurance, Overtime & Penalties
Overtime on public works, and the $25 a day it costs to get it wrong
The rule
Work someone past 8 hours in a day or 40 in a week on a public work without paying at least one and one-half times the basic rate, and you forfeit $25 for that worker for that day on top of the overtime you still owe.
When it applies — and when it does not
- It does not matter whether you required the extra hours or merely permitted them, and the forfeiture runs for each calendar day on which it happened.
- Underpaying the prevailing wage is a different violation with a different number: not more than $200 for each calendar day for each worker, set by the Labor Commissioner on good faith and prior record, plus the wage difference.
- Every employer except the state must secure the payment of workers' compensation, on public and private jobs alike.
Worked contrast
| Overtime trigger (§1815) | over 8 hours in a day or 40 hours in a week |
| Overtime rate (§1815) | not less than 1.5 times the basic rate of pay |
| Overtime forfeiture (§1813) | $25 per worker per calendar day |
| Prevailing-wage underpayment penalty (§1775) | not more than $200 per worker per calendar day, plus back wages |
Common mix-ups
- $25 and $200 are two different penalties: $25 is the overtime forfeiture, $200 is the ceiling for underpaying prevailing wage.
- Workers' compensation is not a public-works-only requirement; the same coverage is required on private jobs.

Public Works
The chapter opens here, in the same statute-checked text as the CSLB Law & Business eBook. 5% of the exam comes from this chapter; this is one of its 12 sections, whole.
Section 3 of 12
Part A — Prevailing wage and the public-works wage regime
What a public work is, and the prevailing-wage requirement
A public work is generally a construction, alteration, demolition, installation, or repair project paid for in whole or in part out of public funds (Lab. Code §§1720, 1720.2). On public works, contractors and subcontractors must pay their workers the applicable prevailing wage — a government-set minimum wage-and-benefit rate for each craft and locality — rather than merely the ordinary state minimum wage (Lab. Code §1771). The requirement generally attaches once the project exceeds $1,000. Prevailing wage is typically substantially higher than minimum wage, and it must be paid to all covered workers on the project.
The exam's favorite trap here is the wage standard itself. Paying the California minimum wage does not satisfy a public-works obligation; the standard is the published prevailing rate, which is usually much higher. A second trap is the idea that prevailing wage only reaches giant projects — it does not. The trigger is a modest $1,000, so even fairly small public jobs are covered.
California example. A licensed contractor wins a $60,000 contract to repaint a county-owned community center. Because the job is paid with public funds and far exceeds $1,000, every painter on the crew must be paid the prevailing wage for the painting classification in that county — not the contractor's usual private-job rate, and not the state minimum wage. Paying anything less is an underpayment the state can pursue.

Frequently asked questions
On a public works project, which wage standard must contractors pay their workers?+
Public works are, broadly, construction projects paid for in whole or part with public funds. On public works (generally where the project exceeds $1,000), contractors and subcontractors must pay their workers the applicable prevailing wage — a government-set minimum wage-and-benefit rate for each craft and locality — not merely the ordinary minimum wage. Prevailing wage is usually substantially higher than minimum wage and must be paid to all covered workers on the project.
Who determines the prevailing-wage rates for public works in California?+
The prevailing-wage rate is not chosen by the contractor. The Director of the Department of Industrial Relations determines the applicable rates for each craft, classification, and locality, and publishes wage determinations that are updated periodically. Contractors must look up the correct current rate for the trade and location of the project and pay at least that rate, including required fringe benefits, to covered workers.
Besides a CSLB license, what registration must a contractor hold to bid on public works?+
Separate from holding a CSLB license, a contractor or subcontractor must be registered with the Department of Industrial Relations to bid on or work on public works projects. This registration regime (from the SB 854 reforms) requires paying a fee and maintaining current registration, and it is a prerequisite to bidding — an unregistered contractor generally cannot be awarded a public works contract. Projects are also reported to DIR.
What records must a contractor keep and furnish to document prevailing-wage compliance on public works?+
On public works, contractors and subcontractors must keep certified payroll records showing each worker's classification, hours, and the wages and benefits paid, and must furnish them as required (often electronically to DIR). Certified payroll is how the state verifies that prevailing wages were actually paid. Failing to keep or submit these records, or falsifying them, carries penalties and can support underpayment findings.
What apprenticeship obligation applies to contractors on public works projects?+
Public works projects generally require contractors to employ apprentices from state-approved apprenticeship programs in a set ratio to journey-level workers for each apprenticeable craft, and to make required apprenticeship contributions. Contractors must request dispatch of apprentices and meet the applicable ratio, supporting workforce training. Failing to use apprentices as required is a violation with its own penalties.
