Contractor Insurance Explained — What You Actually Need and Why It Matters

Contractors are some of the most underinsured business owners in the country. Not because they’re cutting corners, but because most were never walked through what their insurance program should actually look like. They get the minimum general liability policy to satisfy their licensing board, maybe add workers comp because they have to, and assume they’re covered. They’re not. We break this down in our companion video on our YouTube channel, but this guide goes deeper into each coverage type, why it matters, and how the pieces fit together to protect your business, your license, and your ability to get work.

General Liability — The Floor Is Not the Ceiling

In many states, general liability insurance is a licensing requirement for contractors. The minimums vary by state and trade, but they often land somewhere in the range of $100,000 to a few hundred thousand dollars per occurrence. That’s what you need to hold a license. It’s not what you need to actually be protected.

$100,000 in liability coverage can disappear in a single claim. A plumber who accidentally floods a finished basement in a $500,000 home. An electrician whose work leads to a fire. A framing crew working a job site where someone gets hurt and the medical bills start compounding. These aren’t hypotheticals — they’re the kinds of claims that happen in construction every day. As Liberty Mutual notes in their contractor insurance overview, general liability is essential for contractors — and as your business grows, you’ll likely need additional coverages beyond it.

The standard that most contractors should be carrying is at least $1,000,000 per occurrence and $2,000,000 aggregate. In the markets we operate in — Nevada, Utah, Arizona, and California — that’s increasingly the baseline, not the upgrade. And as we’ll cover later in this post, most general contractors won’t let a subcontractor on a job site with anything less than a million in coverage regardless of what the state requires.

Workers Compensation — Required, Enforced, and Non-Negotiable

In most states, if you have even one employee, you are required to carry workers compensation insurance. In construction specifically, these requirements are enforced more aggressively than in almost any other industry. Workers comp covers medical expenses and lost wages when an employee is injured on the job — and construction consistently ranks among the highest-risk industries for workplace injuries. Falls, equipment accidents, repetitive stress injuries — these are real exposures that contractors face on every project.

If you don’t have workers comp and an employee gets hurt, you’re personally liable for their medical bills and lost wages. You’re also facing fines from your state labor commission and potentially losing your contractor license. It’s one of the fastest ways to lose everything you’ve built as a business owner.

If you’re a sole proprietor with no employees, most states allow you to waive workers comp coverage — but you typically can’t just skip it. You usually need to file a formal waiver or exemption with your state’s labor commission. The process varies by state, and failing to file properly can still result in compliance issues even if you technically qualify for the exemption.

One thing sole proprietors rarely consider: if you don’t carry workers comp and you get hurt on the job, there’s no coverage for lost income. Your health insurance may cover the medical bills, but there’s no paycheck replacement while you recover. For a contractor whose income depends entirely on being able to work, that’s a significant gap worth thinking about.

Commercial Auto — Your Personal Policy Probably Doesn’t Cover You

This is one of the most commonly overlooked exposures for contractors. If you’re driving a vehicle that’s owned by your business or used primarily for business purposes — hauling materials, pulling a trailer, driving between job sites — your personal auto insurance likely does not cover it. Most personal auto policies exclude vehicles titled to a business entity or used primarily for commercial purposes. That means an accident on the way to a job site in your work truck could result in a denied claim if you’re relying on personal auto coverage.

There’s also a critical distinction that many contractors miss: general liability insurance does not cover auto accidents. If you cause an accident on the road, that’s an auto liability claim, and it must be covered by a commercial auto policy. GL and commercial auto are entirely separate exposures.

Commercial auto covers liability, collision, and comprehensive for vehicles used in your business, including coverage for employees driving company vehicles. If you’re pulling a trailer — and most contractors are at some point — make sure your policy covers the trailer and its contents. A trailer loaded with materials or equipment that’s involved in an accident is not a loss you want to discover isn’t covered.

Tools and Equipment — The Most Underinsured Area for Contractors

This is probably the biggest coverage gap across the contracting industry, and the reason is simple: most contractors insure the truck but not what’s inside it.

A standard general liability policy does not cover your tools and equipment. A standard commercial auto policy covers the vehicle, not its contents. So if someone breaks into your truck overnight and steals $10,000 worth of tools — which happens constantly — you may have no coverage at all unless you carry an inland marine policy.

Inland marine insurance — also called tools and equipment coverage or a contractor’s equipment floater — covers your tools, equipment, and materials whether they’re in your truck, on a job site, in storage, or in transit. It covers theft, damage, and in some cases mysterious disappearance. The cost is typically very reasonable relative to the value of what you’re protecting. If you’ve spent years building up your tool inventory, you’re one break-in away from replacing everything out of pocket without this coverage.

Surety Bonds — Not Insurance, But Still Required

Most states require a surety bond as part of the contractor licensing process. The bond amount depends on your state and license classification and can range from a few thousand dollars to $50,000 or more. The important thing to understand is that a surety bond is not insurance for you. It’s a guarantee to the public that if you fail to meet your contractual obligations or violate state regulations, there’s money available for a claim. And if a claim is paid against your bond, you are responsible for repaying it.

Most contractors set up their bond through their insurance agent when they first get licensed and then don’t think about it again. That’s fine — just make sure it stays current. If your bond lapses, your contractor license can lapse with it.

Commercial Umbrella — The Best Value in Your Insurance Program

A commercial umbrella policy provides an additional layer of liability coverage that sits on top of your general liability, your commercial auto liability, and your employers liability (the liability component of your workers comp policy). It kicks in when the limits on those underlying policies are exhausted.

For contractors, umbrella coverage matters because the claims that cause the most damage aren’t the routine ones — they’re the catastrophic ones. A worker falls from a roof. A piece of heavy equipment drops onto a vehicle or a person. A fire spreads from your work area to an adjacent property. These are the claims that can blow through a $1,000,000 GL policy. An umbrella gives you an additional layer — typically $1,000,000 or more — that can be the difference between surviving a major loss and shutting down your business. The cost relative to the coverage it provides is usually one of the best values in a contractor’s entire insurance program.

Certificates of Insurance — No COI, No Job

If you work as a subcontractor — and most specialty trade contractors do — the general contractor running the project is going to require a certificate of insurance before you set foot on the job site. This isn’t optional. It’s a contractual requirement, and the GC’s insurance standards are almost always higher than whatever your state licensing minimum is.

A typical GC will require at least $1,000,000 per occurrence and $2,000,000 aggregate in general liability. Many also require commercial auto coverage and proof of workers compensation — even from sole proprietors. And they’ll often require that the GC is listed as an additional insured on your policy, which means your coverage extends to protect them for claims arising from your work on their project.

If you can’t produce a certificate that meets their requirements, you don’t get the job. Contractors lose bids not just because their price was wrong — it also happens because they couldn’t produce the right certificate in time. Your insurance agent should be able to turn a COI around quickly. If they can’t, that’s a problem worth addressing.

Endorsements Most Contractors Don’t Know About

Beyond having the right coverage limits, many general contractors — especially on larger commercial projects — require specific endorsements on your policy before they’ll accept your certificate of insurance. These endorsements modify how your policy responds in certain situations, and if your policy doesn’t include them, your COI won’t satisfy the contract requirements.

Waiver of subrogation means your insurance company agrees not to pursue the GC to recover money paid on a claim. GCs require this so that your carrier doesn’t turn around and sue them after paying out on a loss that occurred on their project.

Primary and noncontributory means your policy pays first, before the GC’s policy is asked to contribute. Without this endorsement, the GC’s carrier could argue that both policies should share the cost of a claim — and that’s not what the GC agreed to in the subcontract.

Per-project aggregate gives you a separate aggregate limit for each project instead of one aggregate that applies across all your jobs. This protects you and the GC: a claim on one project doesn’t eat into the coverage available for your other active jobs.

Most contractors have never heard of these endorsements until a GC’s risk manager rejects their certificate. Now you know what to ask your agent for before that happens. As we discuss in our YouTube video on contractor insurance, this is the kind of detail that separates a properly built insurance program from one that just checks the licensing box.

The Full Picture — What a Properly Insured Contractor Looks Like

When you put it all together, a properly insured contractor carries: general liability at $1,000,000 per occurrence and $2,000,000 aggregate (minimum), workers compensation if they have any employees (with a formal waiver filed if they don’t), commercial auto covering every vehicle and trailer used in the business, inland marine covering tools, equipment, and materials on and off the job site, a current surety bond meeting their state’s licensing requirement, and a commercial umbrella of at least $1,000,000 sitting on top of everything else.

That’s the package. And when it’s structured properly — bundled with the right carrier, with the right endorsements already built in — it’s usually not as expensive as most contractors expect.
