General Contractor Insurance: Covering Every Trade on Your Job

General contractor insurance has a harder job than any single trade policy. A plumber insures plumbing work. An electrician insures electrical work. A general contractor answers for the whole site: your crew, your subs, the structure going up, the neighbor’s property next door, and the finished building for years after you hand over the keys. This guide walks through the full program a GC needs, the subcontractor paperwork that decides whether that program actually works, and the licensing requirements in Nevada, Arizona, California, and Utah.

Why a General Contractor’s Risk Looks Different

When something goes wrong on a jobsite, the claim usually finds the general contractor. You hired the sub. You scheduled the work. The site ran under your control. Plaintiffs’ attorneys know that, and so do the owners and lenders who write your contract requirements.

The labor market is making this sharper. In the 2025 workforce survey from the Associated General Contractors of America and NCCER, 92 percent of firms said they struggle to fill open positions, and 45 percent reported project delays caused by shortages of their own or their subcontractors’ workers. One in five firms said their subs lost workers. Thin crews mean greener labor, stretched supervision, and subs you have never worked with before filling gaps on your schedule. Every one of those pressures raises the odds of a claim, and every one of those claims can reach you.

That is why a GC’s insurance review should spend as much time on the subs’ paperwork as on the GC’s own policies. We will get there. First, the program itself.

The Core General Contractor Insurance Program

General contractor insurance is a stack of policies, each solving a different problem. Here is the core program and what each piece actually does.

Coverage	What It Does for a GC
General liability (GL)	Third party bodily injury and property damage from your operations and your completed work. The policy owners and lenders demand first.
Workers’ compensation	Medical care and lost wages for your injured employees. Required by every state you are licensed in once you have employees, and in some cases before.
Commercial auto	Trucks and trailers moving crews, tools, and materials between sites. Personal auto policies exclude most of this use.
Inland marine / contractors equipment	Tools and equipment at the site, in transit, and in the yard. Theft from jobsites is the loss that shows up most often.
Builders risk	The structure itself while under construction, plus materials on site, in transit, and in storage. See our full builders risk guide.
Commercial umbrella	Extra limits above GL, auto, and employer’s liability. Owners on larger projects increasingly require $5 million or more in total limits.
Contractors professional (E&O)	Design and management errors. Matters most on design-build work, where the GC owns design decisions GL will not touch.
Contractors pollution liability	Silica dust, fuel spills, disturbed contaminants. Standard GL forms exclude most pollution events.
Cyber	Wire fraud on draw payments and vendor invoices. Construction payment chains are a favorite target for spoofed payment instructions.

Not every GC needs every line on day one. A framing-heavy residential GC and a design-build commercial GC carry different stacks. The point of working with an independent agency is matching the stack to the book of work you actually run.

General Liability: How the Engine of the Program Works

Your GL policy carries two limits that matter daily: the per occurrence limit and the general aggregate. The aggregate is the total the policy will pay across all claims in a policy year. Here is the detail many GCs miss: on a standard form, every project you run draws down that one shared aggregate. One bad loss on a single job can drain the limit protecting every other job that year.

The fix is a designated construction project aggregate endorsement, commonly issued as CG 25 03. It gives each project its own aggregate limit. Sophisticated owners often require it, and GCs running multiple concurrent projects should ask for it even when nobody requires it.

The second thing to understand is products-completed operations coverage. Your exposure does not end at the certificate of occupancy. A deck that fails two years after completion, a roof connection that leaks into a finished interior, a stair rail that gives way: these claims fall under completed operations, and they follow you for years. This is also where the “your work” exclusion and its subcontractor exception live. In plain terms, a standard GL form will not pay to redo your own defective work, but the form can respond to property damage in completed operations that arises out of work a subcontractor performed for you. For a GC who subs out most trades, that exception carries real weight. Some carriers remove it by endorsement, so we read for that language on every GC placement.

Finally, watch for residential, condominium, or exterior insulation exclusions on nonstandard forms. A policy that quietly excludes the work you actually do is worse than no quote at all, because you find out at claim time.

General Contractor Insurance Lives or Dies on Subcontractor Paperwork

Here is the claim pattern that produces the largest GC losses in our region. A subcontractor’s employee suffers an injury on your site. Workers’ comp pays him through his employer, and comp law generally shields that employer from a lawsuit. You have no such shield. His attorney sues the general contractor for unsafe site conditions. The industry calls this an action over claim, and it is the reason the paperwork below exists.

Your defense is contractual risk transfer, built from four pieces collected before a sub sets foot on site:

Additional insured endorsements. The sub’s GL policy should name you as an additional insured, and one endorsement is not enough. Coverage for ongoing operations, commonly CG 20 10, protects you while the sub is working. Coverage for completed operations, commonly CG 20 37, protects you after the sub finishes, and construction defect claims tend to arrive in exactly that window. You need both.

Endorsement	Covers You For	When Claims Arrive
Ongoing operations (e.g. CG 20 10)	Injuries and damage while the sub is performing work	During construction
Completed operations (e.g. CG 20 37)	Damage arising from the sub’s finished work	Months or years after completion

Primary and noncontributory wording. This makes the sub’s policy pay first, before yours contributes. Without it, two carriers argue over shares while your loss history takes the hit.

Waiver of subrogation. This stops the sub’s carrier from paying a claim and then chasing you to recover it.

Match the Contract to the Coverage

Indemnity wording that matches the insurance. Your subcontract’s indemnity clause and the sub’s endorsements need to say the same thing. Standard GL forms exclude most assumed liability, then carve coverage back in for an “insured contract,” which includes the kind of tort indemnity a construction subcontract creates. Trouble starts when the subcontract promises broader indemnity than the sub’s policy will honor, or when the states involved limit indemnity by statute. We ask for the subcontract template when we review a GC program, because the contract and the coverage only protect you as a matched set.

The certificate trap. A certificate of insurance proves almost nothing. The standard ACORD certificate states on its face that it confers no rights on the holder. It describes coverage as of its print date, and it does not show exclusions, endorsement wording, or whether the policy lapsed a week later. Collect the certificate, then require copies of the actual endorsements. When a project matters, we help clients read them.

Uninsured Subs Land on Your Audit

Carriers audit contractor GL and workers’ comp premiums after the policy year ends. The auditor reviews your payroll and your payments to subcontractors. The auditor treats every sub without a matching valid certificate for their work period as your employee, then adds their cost to your premium basis. A 1099 does not change this. We have seen audit bills wipe out the entire margin on a project because certificates were never collected or had expired mid-job.

The discipline is simple to describe: collect certificates before mobilization, calendar the expiration dates, and keep the file for every policy period. It is tedious, and it is worth real money twice a year, at audit and at claim time.

What Your General Liability Will Not Cover

Knowing the edges of GL keeps the rest of the program honest. The standard form will not pay for the cost of redoing your own faulty workmanship. It will not cover design or project management errors, which is contractors E&O territory. Injuries to your own employees belong to workers’ comp instead. The form also excludes damage to vehicles, your tools and equipment, most pollution events, and the structure under construction itself, which belongs to builders risk. Each of those gaps has a policy built for it, and the table above maps them.

When the Owner Buys the Insurance: Wrap-Up Programs

On larger projects, especially public work and big commercial builds, you may find the owner or the GC at the top of the chain providing a wrap-up program, called an OCIP when the owner sponsors it and a CCIP when the contractor does. A wrap enrolls every contractor on the project under one GL and workers’ comp program for that site. Enrolling feels like the insurance problem just solved itself. Read the wrap manual before you believe that.

Wraps cover the enrolled project site, and usually nothing else. Your yard, your fabrication shop, your deliveries, and your other jobs still run on your own program. Many wraps also carry thinner completed operations tails than the statutes of repose in our states, which leaves you exposed in the late years when defect claims surface. Your own carrier needs to know about wrap work too. Wrap payroll and receipts should come out of your practice program’s rating basis, and missing that credit means paying twice for the same exposure. We reconcile wrap enrollments at every audit for exactly that reason.

Licensing, Bonds, and Insurance in Nevada, Arizona, California, and Utah

Each of our four states ties contractor licensing to financial responsibility in its own way. Here is the current landscape for general contractors.

State	Licensing Body	Bond	Insurance Notes
Nevada	State Contractors Board (NSCB)	$1,000 to $500,000, set by the Board with your monetary limit	Proof of workers’ comp or exemption at licensure. Your license carries a printed monetary limit under NRS 624.220.
Arizona	Registrar of Contractors (ROC)	Scaled to annual volume under ARS 32-1152; commercial general runs $5,000 to $100,000, dual licenses stack both amounts	License required for work over $1,000. Residential classes fund the Recovery Fund or post a $200,000 bond.
California	Contractors State License Board (CSLB)	$25,000 contractor bond; LLCs add a $100,000 employee/worker bond	LLC licensees must carry at least $1 million in liability coverage. Workers’ comp is mandatory for five classifications even with no employees, and the universal requirement for all licensees was moved to January 1, 2028.
Utah	Division of Professional Licensing (DOPL)	$50,000 for B100 general building contractors	General liability is required for licensure, with minimums raised to $1 million per occurrence and $2 million aggregate effective April 20, 2026. No employees means a Labor Commission coverage waiver instead of comp.

Two of these deserve a flag. Utah’s new liability minimum took effect this spring, and a certificate written at the old $100,000/$300,000 level will now hold up a renewal. And in California, follow-up legislation pushed the widely reported 2026 deadline, which would require every licensed contractor to carry workers’ comp regardless of employees, out to January 1, 2028, while concrete, HVAC, asbestos, roofing, and tree service contractors remain on the mandatory list today. Plenty of articles still print the old dates for both states.

What Drives a General Contractor’s Premium

Carriers rate GC programs on a handful of inputs you can actually manage. Payroll by class code drives workers’ comp. Gross receipts and subcontract costs drive GL, and underwriters rate subs with verified insurance of their own far more favorably than uninsured labor. Project mix matters: residential work, and condos and tract work especially, prices differently than commercial. Claims history follows you for five years. States in your footprint each carry their own rate environment. When we market a GC account, tightening the certificate file and documenting your risk transfer program is often worth more than shopping alone, because underwriters price the discipline they can see.

Seven Questions to Answer Before You Bind

1. Does the GL form include the subcontractor exception to the “your work” exclusion, or has an endorsement removed it?

2. Is there a per project aggregate, or does one shared aggregate cover every job you run?

3. Do any residential, condo, or trade-specific exclusions conflict with the work on your schedule this year?

4. Do your subcontract agreements require ongoing and completed operations additional insured status, primary and noncontributory wording, and a waiver of subrogation?

5. Who in your office owns certificate collection, and does the file cover the full audit period?

6. Do your limits, including umbrella, meet the requirements in the contracts you plan to sign, before you sign them?

7. Does your licensing paperwork in every state match your current coverage, including Utah’s new liability minimums?

“My Subs All Carry Their Own Insurance”

We hear this from strong operators, and the subs’ coverage genuinely matters. Here is what it does not do on its own. Their policy defends them, and it only defends you if the additional insured endorsements say so in writing. The limits they carry may be a fraction of the claim. Their policy may have lapsed since the certificate’s print date, or may carry exclusions aimed at exactly the work they did for you. And when a sub disappears or dissolves before a defect claim surfaces, your completed operations coverage is what remains standing. Sub insurance and GC insurance are layers of the same defense, and both layers need to hold.

Frequently Asked Questions

Do I need general contractor insurance if I subcontract all the work?
Yes. Hiring the subs, controlling the schedule, and owning the contract makes you the target when something goes wrong, during construction and for years after completion.

Is a certificate of insurance from my sub enough?
No. Certificates confer no rights on the holder. Require the additional insured endorsements themselves, for both ongoing and completed operations.

What limits do project owners usually require?
$1 million per occurrence and $2 million aggregate is the common floor on commercial work, and many owners now require umbrella limits of $5 million or more on top. Read the insurance exhibit before you price the job.

Will my GL pay to fix a sub’s defective work?
It will not pay to redo the defective work itself. The subcontractor exception can respond to property damage that results from the sub’s defective work in completed operations, if your form still contains it.

What happens at audit if a sub had no insurance?
The auditor adds that sub’s cost to your premium basis, on comp and on GL. You pay premium as if their crew had been your employees.

Do I need builders risk if the owner says they will buy it?
Confirm it in writing, have them name you as an insured on their policy, and check who pays the deductible. Our builders risk guide covers the details worth verifying.
