Flow-down clauses: what a prime passes to a sub
On California public work, Labor Code section 1775(b) requires six statute copies in the subcontract, periodic review of the sub's certified payroll, corrective action on a shortfall, and an affidavit before final payment. Joint and several liability, withholding and debarment reach a subcontractor with no clause at all. On a utility contract nothing reaches it except through the prime.
The City of Upland's landscape maintenance agreement with Elite Maintenance & Tree Service runs 41 pages. Its flow-down clause is one sentence, and that sentence sits in the recitals on page 1, above the numbered terms:
Contractor shall not subcontract any portion of the work required by this Agreement, except as expressly stated herein, without prior written approval of City. Subcontracts, if any, shall contain a provision making them subject to all provisions stipulated in this Agreement.
The agreement was made April 13, 2026, for a term running July 1, 2026 through June 30, 2029. Everything else in it reaches a crew on the second tier through that second sentence: the insurance limits, the three-year records window in section 3.2.14, the $250 a day of liquidated damages in section 3.2.8.
A smaller set of duties reaches a subcontractor no matter what the subcontract says, because a statute put them there. Which set a duty belongs to decides who pays when the second tier gets it wrong.
Six section numbers go into the subcontract as text
Labor Code section 1775 prices a prevailing wage shortfall, and prevailing wage determinations covers how that number is reached. Subdivision (b) decides whether the prime pays it alongside the sub.
If a worker employed by a subcontractor on a public works project is not paid the general prevailing rate of per diem wages by the subcontractor, the prime contractor of the project is not liable for any penalties under subdivision (a) unless the prime contractor had knowledge of that failure of the subcontractor to pay the specified prevailing rate of wages to those workers or unless the prime contractor fails to comply with all of the following requirements:
All of the following. Missing one is missing the defense. The first is a printing job:
The contract executed between the contractor and the subcontractor for the performance of work on the public works project shall include a copy of the provisions of this section and Sections 1771, 1776, 1777.5, 1813, and 1815.
Six sections, counting 1775 itself.
"Include a copy of the provisions" is the operative phrase. A subcontract reciting that the subcontractor shall comply with all applicable prevailing wage laws reproduces none of the six. A clause naming all six by number reproduces none of them either. The cheap way to satisfy the sentence is an exhibit, six statute printouts behind the signature page, listed on the exhibit index so a reader two years later can see they were attached at execution.
The other three conditions are work the prime does itself
The remaining requirements in subdivision (b) are performed by the prime on its own time, not written into anything.
The contractor shall monitor the payment of the specified general prevailing rate of per diem wages by the subcontractor to the employees, by periodic review of the certified payroll records of the subcontractor.
Upon becoming aware of the failure of the subcontractor to pay his or her workers the specified prevailing rate of wages, the contractor shall diligently take corrective action to halt or rectify the failure, including, but not limited to, retaining sufficient funds due the subcontractor for work performed on the public works project.
Prior to making final payment to the subcontractor for work performed on the public works project, the contractor shall obtain an affidavit signed under penalty of perjury from the subcontractor that the subcontractor has paid the specified general prevailing rate of per diem wages to his or her employees on the public works project and any amounts due pursuant to Section 1813.
Periodic is left undefined. The statute sets no interval, so the subcontract sets it or nobody does. Certified payroll in XML covers the filing floor the subcontractor already runs on, and a review keyed to that filing is the interval a prime can defend.
The affidavit has a fixed position in the schedule: before final payment. It covers two things, the prevailing rate and any amounts due under section 1813. A subcontractor swearing only to the base rate has not sworn to the overtime. On a release order whose last unit closes in November, the affidavit has to be signed and in the file before the November check is cut. A prime that pays first and gathers affidavits at year-end has done the other three conditions and lost the defense anyway.
Nothing obliges a subcontractor to hand its payroll to the prime
Section 1775(b)(2) tells the prime to review the subcontractor's certified payroll. Section 1776(b)(2) says who may demand it:
A certified copy of all payroll records enumerated in subdivision (a) shall be made available for inspection or furnished upon request to a representative of the body awarding the contract and the Division of Labor Standards Enforcement of the Department of Industrial Relations.
The awarding body and the Labor Commissioner's enforcement division. The next paragraph opens the records to the public, and subdivision (e)(1) prices that route:
any copy of records made available for inspection as copies and furnished upon request to the public or any public agency by the awarding body or the Division of Labor Standards Enforcement shall be marked or obliterated to prevent disclosure of an individual's name, address, and social security number
A prime reading a public copy gets hours and rates with the workers' names struck out. Nobody reconciles that against a crew sheet. The prime's route to usable records is a clause in its own subcontract naming the interval, the format and the consequence of missing it.
The exposure runs one way down the tiers. Section 1776(i) leaves the records penalty where the failure happened: "A contractor is not subject to a penalty assessment pursuant to this section due to the failure of a subcontractor to comply with this section." Section 1775(a) does the opposite, which is why subdivision (b) exists at all.
Three duties arrive whether or not the subcontract mentions them
Statutes reach past the signature page in three places on California public work, and none of them wait for a clause.
Source | What it does to the prime |
Makes contractor and subcontractor jointly and severally liable for all amounts due under a final order | |
Turns the prime into the collection agent for a subcontractor's assessment | |
Voids the subcontract with a debarred sub and leaves the wages with the prime |
Section 1727(b) is the one primes discover late:
If the awarding body has not retained sufficient money under the contract to satisfy a civil wage and penalty assessment based on a subcontractor's violations, the contractor shall, upon the request of the Labor Commissioner, withhold sufficient money due the subcontractor under the contract to satisfy the assessment and transfer the money to the awarding body.
The request arrives at the prime, the money moves out of the prime's payable to the sub, and the prime holds the argument with its own subcontractor afterward.
Section 6109 goes further. Subdivision (a) orders that "Every public works project shall contain a provision prohibiting a contractor from performing work on a public works project with a subcontractor who is ineligible," which makes the debarment clause a mandatory piece of the agency's own contract. Subdivision (b) says what happens when the clause is ignored:
Any contract on a public works project entered into between a contractor and a debarred subcontractor is void as a matter of law. A debarred subcontractor may not receive any public money for performing work as a subcontractor on a public works contract, and any public money that may have been paid to a debarred subcontractor by a contractor on the project shall be returned to the awarding body. The contractor shall be responsible for the payment of wages to workers of a debarred subcontractor who has been allowed to work on the project.
A trimming crew debarred under section 1777.1 in March, still cutting in April, produces three separate results. The subcontract is void. Money already paid to that sub goes back to the awarding body. The crew still gets paid, by the prime, out of the prime's own margin.
The agency's list is longer than the statute's
Section 3.3.6 of the Upland agreement writes its own catalog of Labor Code duties and binds both tiers to it:
It shall be mandatory upon the Contractor and all subcontractors to comply with all California Labor Code provisions, which include but are not limited to prevailing wages (Labor Code Sections 1771, 1774 and 1775), employment of apprentices (Labor Code Section 1777.5), certified payroll records (Labor Code Sections 1771.4 and 1776), hours of labor (Labor Code Sections 1813 and 1815) and debarment of contractors and subcontractors (Labor Code Section 1777.1).
Nine section numbers against the statute's six, and the two lists do not line up.
Section | In Labor Code 1775(b)(1) | In Upland section 3.3.6 |
1771 | yes | yes |
1771.4 | no | yes |
1774 | no | yes |
1775 | yes | yes |
1776 | yes | yes |
1777.1 | no | yes |
1777.5 | yes | yes |
1813 | yes | yes |
1815 | yes | yes |
Two separate acts are being asked for. Section 3.3.6 asks for a promise of compliance and binds the subcontractor to it through the conduit clause in section 2.1. Section 1775(b)(1) asks for the text of six statutes to be in the subcontract. A prime can satisfy the agreement in full and still owe the penalty, because the six copies were never attached.
A subcontractor's stop order becomes the prime's delay
Registration under Labor Code section 1725.5 attaches to each contractor separately, and public works contractor registration covers who has to hold it. Section 3.3.7 of the Upland agreement pushes the checking duty up to the prime, then prices the failure:
Any stop orders issued by the Department of Industrial Relations against Contractor or any subcontractor that affect Contractor's performance of Services, including any delay, shall be Contractor's sole responsibility. Any delay arising out of or resulting from such stop orders shall be considered Contractor caused delay and shall not be compensable by the City.
Contractor caused delay is the phrase that costs money. Section 3.2.8 of the same agreement sets liquidated damages at $250 for each calendar day of delay beyond the Performance Time, under Government Code section 53069.85. A stop order served on a second-tier trimming crew stops that crew, pushes the completion date, and starts a $250 clock against the prime. The sub whose registration lapsed pays nothing under this clause.
Money flows down on a clock, and the clock is seven days
Two statutes run the same number at the prime from different directions.
Payment | Source | Deadline | Charge for missing it |
Progress payment | 7 days after receipt, unless otherwise agreed to in writing | 2 percent of the amount due per month | |
Retention | 7 days from receipt of the retention proceeds | 2 percent per month on the improperly withheld amount |
Section 7108.5(a) also fixes what a prime may hold back:
In the event that there is a good faith dispute over all or any portion of the amount due on a progress payment from the prime contractor or subcontractor to a subcontractor, the prime contractor or subcontractor may withhold no more than 150 percent of the disputed amount.
The words unless otherwise agreed to in writing are the flow-down handle. Seven days is the default, and the subcontract can move it. Nothing in section 7108.5 allows a subcontract to move the 2 percent, and nothing allows it to lift the 150 percent ceiling. A $40,000 subcontractor invoice funded by the agency and held a month past the seventh day carries $800, plus the prevailing party's attorney's fees if it goes to collection.
A sub's claim reaches the agency through the prime
A second-tier crew has no contract with the city. Public Contract Code section 9204(d)(5) builds the pass-through:
If a subcontractor or a lower tier subcontractor lacks legal standing to assert a claim against a public entity because privity of contract does not exist, the contractor may present to the public entity a claim on behalf of a subcontractor or lower tier subcontractor. A subcontractor may request in writing, either on their own behalf or on behalf of a lower tier subcontractor, that the contractor present a claim for work which was performed by the subcontractor or by a lower tier subcontractor on behalf of the subcontractor. The subcontractor requesting that the claim be presented to the public entity shall furnish reasonable documentation to support the claim. Within 45 days of receipt of this written request, the contractor shall notify the subcontractor in writing as to whether the contractor presented the claim to the public entity and, if the original contractor did not present the claim, provide the subcontractor with a statement of the reasons for not having done so.
The prime keeps the discretion and inherits a deadline. A written request delivered March 3 needs a written answer by April 17, and a refusal has to carry reasons. Section 9204(g) applies the section to contracts entered into on or after January 1, 2017.
The section carried a repeal date of January 1, 2027. Senate Bill 33, authored by Senator Cortese and chaptered July 16, 2026 as Chapter 99, deletes that date. The claim process continues past the old sunset.
The insurance a prime carries does not reach the sub's crew
Insurance is the flow-down that has to be bought twice. Section 3.2.11.1 of the Upland agreement bars a subcontractor from starting until the City has evidence of its coverage, and section 3.2.11.6 names the endorsement:
The Contractor and the City shall be named as additional insureds on all subcontractors' policies of Commercial General Liability using ISO form 20 38, or coverage at least as broad.
Two additional insureds on the sub's own policy, one of them the prime. Section 3.2.11.4 pushes the subrogation waiver down as well, requiring the Contractor to "require similar written express waivers and insurance clauses from each of its subcontractors." Bonds and insurance limits covers the difference between the certificate that reports coverage and the endorsement that grants it. On the second tier that difference decides whether a prime named on a certificate is actually an insured under the policy.
On a utility contract the prime is the whole conduit
An investor-owned utility contract is not public work, so none of the Labor Code machinery above runs on it. What reaches a subcontractor is whatever the utility wrote into the prime's agreement, plus whatever the prime copied into the subcontract.
Utilities write that reach into definitions. PG&E's Utility Standard SAFE-3001S, Revision 5, effective March 28, 2024, defines a Subcontractor as a contractor "retained by a Prime-Contractor, or by any Subcontractor at lower tiers, to provide services on behalf of PG&E." Section 3.3 then puts a gate in front of every one of them:
Contractor shall not allow any Subcontractor to start any Work for which Pre-qualification is required without first obtaining written approval from PG&E that the Subcontractor has satisfied PG&E's Pre-qualification requirements.
Section 4.8 makes the prime the administrator of that gate. It submits each sub on the Exhibit 1A form, carrying the sub-tier's name, evaluated risk level, ISN identification and verification of prequalification. It monitors status continuously, and if a subcontractor becomes unqualified mid-job the prime notifies PG&E immediately. Section 3.4 puts every cost of all that at the Contractor's sole cost and expense, including the fees charged by PG&E's prequalification administrator. ISNetworld grades covers what the grade on that form is made of.
One PG&E exhibit uses the term outright. Exhibit 3, Federal Government Contracting Requirements, dated April 2026, applies where the work has a direct relationship to a deliverable requirement of a federal contract, and instructs that "Contractor will flow down all FAR clauses relevant to its lower-tier Subcontractors."
That exhibit reaches a narrow slice of utility work. The structure it assumes is the general one: the utility binds the prime, and the prime is the only party that can bind anyone below it. How the rest of that stack is ordered sits in utility MSA structure.
What a subcontractor cannot borrow from the tier above
Four qualifications look like they flow down and do not. Each tier holds its own or does not work.
Qualification | Who must hold it | Where it is covered |
Contractor's license for the trade performed | Every contractor and subcontractor performing licensed work | |
Public works contractor registration | Each contractor and subcontractor separately | |
Commercial general liability with the right endorsement | Each tier, with the tier above named as additional insured | |
Utility safety prequalification and grade | Each contractor and sub-tier, submitted individually |
A prime holding a C-49, an active registration, an endorsed liability policy and an ISN grade of A has qualified exactly one company. The crew on the second tier is unqualified until it holds all four in its own name.
Where this lands on a contract
Eight documents decide whether a flow-down obligation was actually performed, and all eight exist before the first dispute.
Obligation | Paper that shows it was performed |
The conduit clause | The prime agreement's subcontracting section, which is often in the recitals rather than the numbered terms |
Six statute copies in the subcontract | The exhibit index, checked against Labor Code section 1775(b)(1) |
The payroll review interval | A clause the prime writes, since section 1776 gives it no standing to demand records |
The final payment affidavit | Signed under penalty of perjury, dated before the last check, covering rate and section 1813 amounts |
Registration status of every tier | The DIR registration search, re-run on the date of each release order |
Debarment screening | Labor Code section 1777.1 and 1777.7 lists, because a hit voids the subcontract retroactively |
The sub's own insurance | An endorsement naming both prime and owner, not the prime's own certificate |
Utility prequalification for each sub-tier | The submitted approval form, dated before the sub's first shift |
The pattern is the same at a city and at a utility. Obligations move down one contract at a time, and exposure moves up without needing a contract at all. A prime that reads its own agreement as the list of things it must copy into the tier below is reading it correctly. A prime that treats the statute's list as satisfied by the agency's list has copied the wrong page.

Frequently asked questions
Does a clause saying the subcontractor shall comply with all prevailing wage laws satisfy Labor Code section 1775(b)(1)?
No. Section 1775(b)(1) requires that the subcontract include a copy of the provisions of section 1775 and of sections 1771, 1776, 1777.5, 1813 and 1815. A covenant of compliance promises an outcome. The statute asks for the text of six sections to be physically in the document. The usual way to satisfy it is an exhibit of six statute printouts named on the exhibit index, so a later reader can see they were attached at execution.
Can a prime contractor demand a subcontractor's certified payroll records?
Only under the subcontract. Labor Code section 1776(b)(2) requires certified copies to be furnished on request to a representative of the awarding body and to the Division of Labor Standards Enforcement. Section 1776(b)(3) opens the records to the public, and section 1776(e)(1) requires public copies to be marked or obliterated to hide each individual's name, address and social security number. A prime is neither the awarding body nor the Labor Commissioner, so its only route to usable records is a clause it writes itself.
How long does a prime have to pay a subcontractor on a California public works contract?
Business and Professions Code section 7108.5(a) sets seven days after receipt of each progress payment, unless otherwise agreed to in writing, and allows withholding of no more than 150 percent of a good faith disputed amount. Section 7108.5(b) sets a penalty of 2 percent of the amount due per month. Public Contract Code section 7107(d) sets the same seven days for a subcontractor's share of retention proceeds, and section 7107(f) sets the same 2 percent per month charge.
What happens if a subcontractor is debarred in the middle of a job?
Public Contract Code section 6109(b) states that a contract on a public works project between a contractor and a debarred subcontractor is void as a matter of law, that the debarred subcontractor may not receive public money, and that any public money already paid to it shall be returned to the awarding body. The same subdivision keeps the prime responsible for paying the wages of the debarred subcontractor's workers. Section 6109(a) requires every public works project to contain a provision prohibiting work with an ineligible subcontractor.
Can a second-tier subcontractor file its own claim against a public agency?
Not directly. Public Contract Code section 9204(d)(5) addresses the subcontractor that lacks standing because privity of contract does not exist. The subcontractor requests in writing that the contractor present the claim and furnishes reasonable documentation. Within 45 days of that written request the contractor must notify the subcontractor in writing whether the claim was presented, and if it was not, give the reasons. Section 9204(g) applies the section to contracts entered into on or after January 1, 2017.
