What Happens If a Subcontractor Has No Insurance?

Say Marco, a small GC, hires a drywall sub for a retail build‑out. Mid‑project, the sub’s helper falls off a ladder and breaks an arm. The sub has no insurance. The client wants proof Marco will cover medical bills and delays. OSHA asks who controlled the site. Marco’s insurer says the claim could be complicated because the subcontractor was uninsured. Suddenly, a routine job is Marco’s biggest headache.

Here’s the short answer: if a subcontractor has no insurance, you can be pulled into lawsuits for injuries or property damage, face OSHA citations as the controlling employer, be charged workers’ comp premium for the sub’s labor, and risk contract default. In several states, you may even be responsible for workers’ comp benefits to the uninsured sub’s injured worker; meanwhile, your own general liability may be narrowed by endorsements when you use uninsured subs.

Key takeaways

• Uninsured subs push risk upstream. If someone’s hurt or property’s damaged, you’ll likely be sued with them—and your client may look to you first. The Insurance Information Institute explains how commercial general liability (CGL) responds to bodily injury and property damage. (iii.org)
• OSHA can cite multiple employers on one site. As the controlling employer, you can be cited even if another firm created the hazard.
• As of October 2026, federal OSHA maximum penalties remain at $16,550 per serious or other‑than‑serious violation and $165,514 per willful or repeat violation. (osha.gov)
• Many states treat uninsured subs as your responsibility for workers’ comp. Examples include Minnesota’s statute making the GC liable if a sub lacks coverage, and Virginia’s rule that contractors must count sub employees when deciding if coverage is required. (dli.mn.gov)
• Contracts usually require subs to carry CGL and workers’ comp, name you additional insured, and deliver a current certificate. A certificate alone doesn’t grant coverage—endorsements do. (amp.insurancejournal.com)
• The fix is simple: verify coverage up front, set requirements in writing, and don’t let uninsured subs start work.

What actually happens if a subcontractor has no insurance?

Four things tend to happen, often at the same time:

• A claim targets you. Plaintiffs cast a wide net. Your CGL may defend you, but some contractor policies limit coverage when work is done by uninsured subs or when you didn’t secure additional insured status from them. (insurancejournal.com)
• OSHA looks to who controlled the site. Under its multi‑employer policy, OSHA can cite the exposing, creating, correcting, and controlling employers; GCs commonly qualify as “controlling.”
• Your workers’ comp or the state may treat the sub’s workers as yours. In several states, the GC is liable for benefits if the sub lacks a policy.
• You pay more at audit. General liability premiums for contractor classes are often audited on payroll or subcontracted cost; uninsured subcontractor costs can be included in that base, raising your premium. (content.naic.org)

Could you be liable for an uninsured subcontractor’s worker injury?

Yes—this is where many GCs get surprised. Multiple states make the general or hiring contractor responsible if the sub lacks workers’ comp:

• Minnesota: GC (or intermediate contractor) is liable for benefits owed to an injured worker of a non‑insured sub.
• Virginia: when counting whether you must carry WC, you must include the headcount of your subs’ employees; carriers can charge premium for subs, even sole proprietors. (workcomp.virginia.gov)
• South Carolina: a GC is liable for statutory employees if subs lack WC. (wcc.sc.gov)
• New York: a worker injured while performing services for a contractor is presumed the contractor’s employee for WC, DBL, and PFL purposes, subject to the independent‑contractor test. (apps.wcb.ny.gov)
• Washington: prime contractors can be held responsible for subs’ unpaid WC premiums. (lni.wa.gov)

Texas is different because coverage is elective, but even there, the Labor Code allows a GC to elect to provide WC for subs and treats the GC as the employer for WC purposes when an agreement is in place. In all cases, check your state’s rules and speak with a licensed agent or attorney before assuming a 1099 label solves WC obligations. (tcss.legis.texas.gov)

Who pays if the uninsured sub causes injury or property damage?

• Your client or the injured party will likely name you in the lawsuit. A standard CGL covers legal defense and damages for bodily injury and property damage up to policy limits, but coverage hinges on your policy language. The Insurance Information Institute’s overview is a good plain‑English explainer.
• Risk transfer matters. Many contractor CGL policies narrow coverage when you use subs who don’t carry their own CGL or don’t add you as additional insured. Industry articles highlight “subcontractor warranty” or other endorsements that can torpedo coverage when subs are uninsured or improperly documented.
• Certificates aren’t insurance. A COI is just evidence; it doesn’t grant rights. To share a sub’s coverage, you need the correct additional insured endorsement(s) tied to your written contract.
• OSHA exposure remains. You can be cited as the controlling employer even if the sub created the hazard—another reason uninsured, unsafe subs are expensive. As of October 2026, the maximum OSHA penalties remain $16,550 (serious/other‑than‑serious) and $165,514 (willful/repeat).

What insurance should you require from every subcontractor?

At a minimum:

• Commercial general liability with additional insured status to you for ongoing and completed operations, primary and non‑contributory wording, and a waiver of subrogation where appropriate.
• Workers’ compensation as required by your state; if your state allows exceptions, your contract can still require coverage. In several states, if the sub has no WC, liability can flow to you.
• Auto liability if the sub uses vehicles on your job (owned, hired, and non‑owned).
• Umbrella/excess liability sized to the job.
• Consider OCP (Owners & Contractors Protective) where it fits the project and contract structure.

How do you check a subcontractor’s insurance—and what would you do before they start?

• Get the certificate from the sub’s agent, not the sub. Make sure policy numbers, effective/expiration dates, and limits are filled in. Then ask for the additional insured endorsements that actually confer your status (for ongoing and completed ops). A certificate alone doesn’t amend coverage.
• Verify workers’ comp. Many states let you confirm WC coverage online. In California, the Department of Industrial Relations explains employer WC duties and how coverage is enforced; other states provide similar employer FAQs and lookups. In Virginia, regulators warn that contractors can be charged premium for subcontractors—even sole proprietors—so documentation matters.
• Align with your contract. The National Association of Home Builders’ consumer checklist reminds you to confirm workers’ comp and general liability before work begins. Government owners often require naming the owner as additional insured—your private contracts can mirror that discipline.
• Keep it current. Re‑verify if the job runs past the policy expiration date on the COI.

Questions to ask your agent before mobilization

• Do any endorsements on my CGL limit coverage when I hire uninsured subs or fail to obtain additional insured status (e.g., “subcontractor warranty” or “your‑work” limitations)?
• If a sub lacks WC, how will my WC audit treat those labor costs this year?
• What AI endorsement from my subs will satisfy my contract—blanket by written contract, or a specific CG 20 10/20 37 pair?
• Should I require primary/non‑contributory and a waiver of subrogation on GL and WC? If so, do my policies align?

Frequently asked questions

Bottom line

If a subcontractor has no insurance, the risk lands on your desk: lawsuits, OSHA exposure, and workers’ comp responsibility, plus premium charges at audit. Make insurance a gate to the job, not an afterthought: require CGL and workers’ comp, get additional insured endorsements, verify coverage in your state’s WC system, and keep everything current.
