Attorney Advertising. This article was prepared with the assistance of artificial intelligence and reviewed by Oaks Law Firm prior to publication.

A general contractor can be held liable for a subcontractor’s unpaid wages under California Labor Code §218.9, and, depending on how much control the contractor retained over the work, may also share liability when a subcontractor’s negligence injures someone on the jobsite. Indemnity obligations between the two are capped by Civil Code §§2782 and 2782.05. Which party actually pays often comes down to contract language, insurance, and how much operational control the general contractor kept for itself.

TL;DR:

  • A contractor can be held liable for a subcontractor’s unpaid wages on contracts after January 1, 2026, if the subcontractor defaults, with limits set by law.
  • Liability for jobsite injuries depends on the degree of operational control retained by the contractor and whether safety was delegated or directly supervised.
  • Indemnity clauses are enforceable only if they do not require a subcontractor to cover the contractor’s sole negligence and include proper tender procedures and insurance documentation.
  • Verifying insurance coverage requires checking for attached endorsements, primary and noncontributory status, and matching policy limits before construction begins.
  • Proper documentation, including signed contracts, insurance certificates, and operational control records, is critical for wining disputes related to unpaid wages or injuries.

Understanding Contractor vs Subcontractor Liability in California

Three statutes do most of the work in California construction liability disputes, and each one answers a different question.

Labor Code §218.9 targets unpaid wages. Starting with contracts entered into on or after January 1, 2026, a direct contractor on a private construction project can be held jointly liable for a subcontractor’s unpaid wages, fringe benefits, and related penalties and interest, subject to specified limits and procedural requirements. The statute exists because subcontractor wage theft has historically left workers with an empty judgment against a subcontractor that closed up shop. The general contractor becomes a second, often better funded, target.

Civil Code §2782.05 governs indemnity and defense in construction contracts. It restricts how far a subcontractor’s indemnity obligation to a general contractor can reach, requires a written tender of the claim, and gives the subcontractor the right to elect whether to defend the claim itself or reimburse defense costs as they’re incurred.

Civil Code §2782 sets the outer boundary. It voids indemnity clauses that try to make one party cover the other party’s sole negligence.

  • §218.9 addresses money owed to workers, not injury claims.
  • §2782.05 addresses who pays for the legal defense and how that gets divided.
  • §2782 addresses what indemnity language is even enforceable in the first place.

The gap between them: none of these statutes decide who is negligent for a jobsite injury. That question runs through case law instead.

When Does a Contractor Become Liable for a Subcontractor’s Actions?

Liability attaches in a handful of recognizable patterns, and each one has its own proof requirements.

  1. Unpaid wages. If a subcontractor stiffs its crew, the workers (or the Labor Commissioner) can pursue the direct contractor under §218.9. Payroll records, certified payroll on public jobs, and the prime contract identifying the subcontractor all matter here. This is a wage claim, not a tort claim, so it moves through different channels than an injury lawsuit.
  2. Negligence and delegated control. Under the doctrine from Privette v. Superior Court, a general contractor that hires an independent subcontractor generally isn’t liable for injuries to the subcontractor’s own employees, because workers’ compensation is presumed to cover that risk. But Tverberg v. Fillner Construction Co. shows the limits of that shield. In Tverberg, the California Supreme Court held that when a contractor delegates control over safety on inherently dangerous work, the party actually controlling that work bears the corresponding risk. Retain more control, retain more exposure.
  3. Joint employer disputes. When a general contractor sets schedules, supervises crews directly, or controls hiring and firing on paper only, courts and agencies may treat it as a joint employer for wage-and-hour or workplace-safety purposes, regardless of what the subcontract says.

A framing crew shows up short on payroll checks: that’s a §218.9 case. A subcontractor’s uncovered trench collapses on a worker: that’s a Privette/Tverberg analysis of who controlled the excavation plan.

Indemnity and Defense Clauses: What Actually Holds Up

Most subcontracts include a clause requiring the subcontractor to defend and indemnify the general contractor against claims “arising out of” the sub’s work. California law doesn’t let that language run unchecked. Under Civil Code §2782, a clause that tries to make a subcontractor cover the general contractor’s own sole negligence is void as against public policy. Civil Code §2782.05 goes further, requiring a written tender before defense obligations kick in and letting the subcontractor choose to defend the claim directly or pay costs as incurred.

A subcontract holds up better in a dispute when it includes:

  • Indemnity language scoped to the subcontractor’s own negligent acts, errors, or omissions, not blanket liability.
  • A defined tender procedure spelling out how and when a claim gets forwarded.
  • Flow-down clauses that mirror the prime contract’s warranty and defect obligations.
  • Insurance requirements referenced directly inside the indemnity clause, not left as a separate afterthought.

Pro Tip: Attach the certificate of insurance and the additional insured endorsement as exhibits to the subcontract itself. A clause promising insurance means little if nobody checks that the actual policy matches it before work starts.

Verifying Insurance Before Work Begins

A certificate of insurance is a summary, not a guarantee. The policy underneath can exclude the exact work being performed, and a COI by itself often fails to catch that.

Four coverage types matter on most jobs: commercial general liability (bodily injury and property damage), workers’ compensation (mandatory for any subcontractor with employees), commercial auto (for vehicles and equipment transport), and, on design-related trades, professional liability.

Before a subcontractor sets foot on site, confirm:

  • The general contractor is named as an additional insured on the CGL policy, with the endorsement attached, not just referenced.
  • The policy is primary and noncontributory, so it pays first instead of splitting costs with the contractor’s own coverage.
  • A waiver of subrogation is in place so the subcontractor’s insurer can’t turn around and sue the contractor after paying a claim.
  • Policy limits actually match the scope and risk of the work, not just a generic minimum.

Missing an endorsement is one of the most common ways a general contractor discovers, mid-lawsuit, that coverage it assumed existed simply isn’t there.

What to Do if You’re Unpaid or Injured on a Jobsite

  1. Preserve records immediately. Payroll stubs, the subcontract, certified payroll reports, texts about scope changes, and any correspondence about safety or scheduling all become evidence.
  2. Send a written tender or demand. For wage claims, that may mean a demand letter or a Labor Commissioner filing. For injury claims involving indemnity, §2782.05 requires the tender in writing before defense duties attach.
  3. File the right claim. Wage disputes typically go to the Labor Commissioner or civil court; injury claims may route through workers’ compensation first, with a separate civil suit against a third party (not the direct employer) still available in many cases.
  4. Track your deadlines. California’s general statute of limitations for personal injury claims is two years under CCP §335.1. If a government entity owns the project or is otherwise involved, a government claim under Gov. Code §911.2 must typically be filed within six months of the injury, well before any lawsuit can proceed. Exceptions exist for minors, delayed discovery of an injury, and certain government-employee circumstances, so don’t assume a deadline has passed without checking your specific facts.
  5. Talk to an attorney before signing anything. Bring the subcontract, any COIs, correspondence about the incident, and a timeline of events to your first meeting. Learn more about how construction accident claims typically unfold in California.

How Oaks Law Firm Evaluates These Cases

Oaks Law Firm takes on a limited number of cases each year, which means the attorneys who review your contractor or subcontractor dispute actually have time to dig into the contract file instead of skimming it. That screening starts with the paper trail: payroll records, the subcontract itself, certificates of insurance and their endorsements, any written tender of a claim, and witness accounts from people who were actually on site.

From there, representation generally moves through investigation, a formal tender to the responsible party or insurer, negotiation, and litigation if a fair resolution doesn’t materialize. Readers dealing with a jobsite injury can review how construction zone accident claims get built from the ground up. A free case evaluation is the starting point, and representation on personal injury matters is handled on contingency, meaning you owe nothing unless the case results in a recovery.

Contractual Risk Allocation Between Contractors and Subcontractors

The prime contract and the subcontract aren’t mirror images of each other, and treating them that way is a common mistake. The prime contract sits between the owner and the general contractor and typically makes the general contractor responsible for the entire project’s completion and quality, including work performed by every subcontractor on the job. The general contractor answers to the owner for the whole project, even for defects it didn’t personally create.

That’s exactly why subcontracts need their own, carefully drafted risk allocation. A general contractor that wants to pass liability down to the subcontractor responsible for a defect needs a subcontract that actually says so, in language that survives §2782’s limits on indemnifying sole negligence. Vague “arising out of” language, without a defined scope tied to the sub’s own work, is one of the most frequent reasons a pass-through claim fails in court.

Risk allocation typically breaks down like this in a well-drafted relationship:

Risk area Typically allocated to
Defects in subcontractor’s own scope of work Subcontractor
Overall project completion and coordination General contractor
Site safety for delegated, controlled work Whoever holds operational control
Owner relationship and payment flow General contractor
Wage compliance for sub’s own employees Both, under §218.9

Subcontractors carry narrower, more specific risk. Contractors carry broader, project-wide risk, but can shift specific pieces of it downstream only when the contract language is precise enough to survive judicial scrutiny.

Workers’ Compensation and Jobsite Injury Liability

Workers’ compensation changes the entire liability calculation for jobsite injuries, and a lot of confusion on this topic traces back to not understanding that shift. When a subcontractor’s own employee gets hurt on the job, workers’ compensation is generally the exclusive remedy against that worker’s direct employer. That’s true regardless of whether the employer was careless.

That’s also the foundation of the Privette doctrine mentioned earlier. Courts presume that a subcontractor’s workers’ comp premiums already account for on-the-job injury risk, so a general contractor that hired an independent subcontractor typically isn’t also on the hook in tort for injuries to that subcontractor’s crew.

But that presumption isn’t absolute. Tverberg carved out situations where the general contractor kept enough control over safety conditions that it functioned more like a direct supervisor than a hands-off hirer. When that happens, the injured worker may have a viable claim against the general contractor separate from the workers’ comp system, because the contractor’s own conduct, not just the sub’s, contributed to the injury.

There’s also a distinction between an injured subcontractor employee and an injured third party, like a pedestrian, a delivery driver, or a neighboring property owner. Workers’ comp exclusivity doesn’t apply to third parties at all. A visitor hurt by falling debris from a construction site can generally sue whichever party, contractor or subcontractor, was negligent, without running into any workers’ comp bar. That’s often where the most significant civil exposure sits for both contractors and subcontractors.

Construction Defects: Who Actually Pays

Defective work claims split along a fault line that’s easy to state and harder to apply: whoever performed the deficient scope of work generally bears responsibility for it, but the general contractor often answers first because the owner’s contract runs through them.

If a subcontractor’s electrical work causes a fire two years after occupancy, the homeowner or property owner typically sues the general contractor, since that’s who they contracted with. The general contractor then has to look to its subcontract to recover from the electrical sub, assuming the indemnity and warranty language actually covers the defect and survives §2782’s limits on indemnifying the contractor’s own negligence.

This is where documentation becomes the difference between recovering costs and eating them. A general contractor with a clean paper trail (the subcontract, change orders, inspection reports, and correspondence showing the sub controlled that scope) has a real pass-through claim. A general contractor without that paper trail is stuck arguing after the fact about who did what, often years after the relevant crew has moved on to other jobs.

Warranty periods matter here too. Many subcontracts include a one-year or longer warranty period specific to that trade’s work, running separately from the statute of limitations that applies to any eventual lawsuit. A subcontractor’s warranty expiring doesn’t necessarily end the general contractor’s exposure to the property owner, which is exactly why the underlying indemnity language needs to outlast the warranty term.

Documenting the Subcontractor Relationship the Right Way

Every liability scenario in this article gets easier to resolve, or harder, based on documentation that either exists or doesn’t. That’s not a small detail. It’s often the entire case.

At minimum, a general contractor should keep on file for every subcontractor relationship:

  • A signed, written subcontract with clearly scoped work, indemnity language limited to the sub’s own negligence, and a defined tender procedure.
  • Current certificates of insurance with the additional insured endorsement, primary/noncontributory language, and waiver of subrogation actually attached, not just referenced.
  • Verification of the subcontractor’s contractor’s license status, since hiring an unlicensed subcontractor can create separate exposure under Business and Professions Code §7031 and can complicate recovery down the line.
  • Payroll compliance documentation, especially on public works jobs requiring certified payroll.
  • A record of who directed the work on a day-to-day basis, since that operational control question resurfaces in nearly every negligence dispute.

None of this is complicated to collect at the time a subcontract is signed. It becomes very difficult to reconstruct two years later, after a lawsuit has already been filed.

Public Works vs. Private Construction: Different Rules

Public works projects in California layer on obligations that private jobs don’t carry. Certified payroll reporting, prevailing wage requirements, and stricter licensing verification all apply on public projects, and general contractors face additional statutory exposure if a subcontractor’s payroll practices fall short. Payment bond claims are also standard on public jobs, since a mechanic’s lien generally isn’t available against public property, so unpaid subcontractors instead pursue the bond.

Private construction liability leans more heavily on the contract terms the parties actually negotiated, along with the statutory framework covered throughout this article, meaning §218.9, §2782, §2782.05, and the Privette/Tverberg line of cases. There’s more room for negotiated risk allocation on a private job, but also less of a statutory safety net if the subcontract itself is poorly drafted.

Both categories share the same underlying negligence and indemnity principles. What changes is the procedural overlay, and a general contractor working across both public and private projects needs separate compliance checklists for each.

What Actually Matters in These Cases

The conventional advice on contractor and subcontractor liability tends to fixate on picking the right boilerplate indemnity clause, as if the right paragraph solves the problem. It doesn’t. I’ve seen the pattern play out the same way too often: a contract with airtight-sounding indemnity language, paired with an insurance file nobody actually checked, and a subcontractor’s policy that excluded the exact work being performed. The clause was fine. The verification behind it wasn’t.

If you take one thing from this explainer, make it this: insurance verification deserves at least as much attention as contract language, and most people get that priority backwards. A subcontract can allocate risk perfectly on paper, but if the additional insured endorsement was never attached to the actual policy, that allocation is worthless when a claim lands.

The second thing worth prioritizing is documentation of operational control, because that’s the fact question courts keep coming back to under Privette and Tverberg. Who actually directed the work? Who set the safety protocol? Contracts rarely answer that honestly, and job site records usually tell the real story. Keep them.
