What Insurance Does a California Contractor Actually Need?

A licensed California contractor needs four things: a $25,000 CSLB license bond, Workers Comp, general liability, and commercial auto for any vehicle used for work. The bond is required to keep your license active, Workers Comp is required by law once you have even one employee, and GL, Workers Comp, and auto are the certificates a GC will ask to see before you start.

Tools and equipment coverage and an umbrella policy aren't required, but they close the two gaps that hurt contractors most often: stolen gear and a claim bigger than your limits. Here's what each one does, which ones a GC checks, and how to tell if you're actually covered.

The Six Coverages at a Glance

The first four are the must-haves. The last two are the ones we recommend adding as your jobs and your equipment get bigger.

Coverage	What It Covers	Who Requires It	Risk If Missing
Contractor license bond	A guarantee that you'll follow California licensing law and the terms of your contracts	California Contractors State License Board (CSLB), to hold an active license	License suspension; a paid claim makes it harder to get bonded again
Workers Comp	Medical expenses and lost wages for employees hurt on the job	California law, for any employer with one or more employees	You're directly liable for medical costs and a possible lawsuit
General liability	Injury or property damage claims tied to your work	Not the law, but standard practice; most clients require it before work starts	You're personally on the hook for damages and legal costs
Commercial auto	Accidents involving vehicles used for the business	Any work vehicle; personal auto policies typically exclude business use	Claims denied under your personal policy
Tools & equipment	Theft of or damage to your tools and equipment	Not required, but strongly recommended for jobsite risk	Project delays and out-of-pocket replacement
Umbrella	Extra limits above your underlying liability policy	Recommended for larger or higher-value projects	Exposure beyond your standard limits on a severe claim

Which Ones Will a GC Actually Ask to See?

Before you start new work, you should be able to produce four things on short notice:

• Proof of active general liability insurance
• A contractor bond that checks out with the CSLB
• Proof of Workers Comp for every crew member
• Proof of commercial auto coverage for your work vehicles

In practice, the GC's paperwork centers on your certificate of insurance. GL is the one every GC asks for, usually at $1 million per occurrence and $2 million aggregate, often with the GC named as additional insured. Workers Comp is the next thing they check. Commercial auto shows up when you're driving for the job, and many GC subcontracts ask for $1 million in auto liability.

The bond works a little differently. It's filed with the CSLB, so it shows up when a GC or client runs your license through the CSLB's license lookup. If your bond lapses, your license goes with it, and that's the kind of thing a GC notices.

Contractor License Bond: Required to Hold Your License

A contractor license bond isn't insurance. It's a financial guarantee, and it's a condition of holding an active California license. If you abandon a project, break licensing law, or don't live up to your contract, a claim can be made against the bond.

Bonds and insurance get mixed up a lot, but they do different jobs:

• Insurance responds to accidents and damage during the work.
• A bond responds to a contractor abandoning work, doing substandard work, or violating state licensing law.
• A claim can be filed directly against the bond, and a paid claim puts your license at risk.

California's $25,000 requirement

The CSLB requires every licensee to keep a $25,000 contractor license bond on file, up from $15,000 before 2023. That's the bond amount, not what you pay for it, but it matters when you budget your overhead and when you think about how much a claim could cost you.

According to the California Contractors State License Board, the bond is a condition of licensure meant to protect consumers and employees. It's not a substitute for your own liability coverage. A few specifics worth knowing:

• The bond covers licensing violations, not just abandoned work.
• More than one party can file a claim against the same bond, which can use up its limit quickly.
• If your bond is used up, you have to post a new one to keep your license active.

Workers Comp: Required the Moment You Have a Crew

Workers Comp covers medical expenses and lost wages for employees injured on the job. In California, it's required for any employer with even one employee.

According to the California Department of Industrial Relations' employer information on workers' compensation, any employer with one or more employees in the state needs valid coverage. That includes nearly every contracting crew working in California. The CSLB also requires certain license classifications to carry it with no employees at all, and that requirement extends to every active license by January 1, 2028.

Letting coverage lapse, even briefly between jobs or during a slow season, is one of the most common and most expensive gaps we see.

What happens when someone gets hurt and there's no coverage

Without Workers Comp, your business is directly exposed the moment a crew member is injured on site. This happens more often than most contractors expect, especially for smaller outfits that grow their crew faster than their coverage.

Working as an uninsured sub under a GC who has coverage doesn't protect you, either. Many GCs require their subs to carry their own Workers Comp, and without it you may be counted under their policy and back-charged. Here's what typically follows an uninsured injury on site:

• No employer policy pays the medical bills, so your business becomes the target.
• The injured worker's attorney looks for any insured party connected to the job.
• Resolving the claim can take months and run up legal fees, no matter how it ends.
• A complaint to the licensing board can follow alongside the injury claim.

General Liability: The Policy Under Everything Else

General liability covers the cost when your work causes property damage or injury to someone else. It's the policy underneath everything else you do.

If your crew breaks a water line, damages a neighbor's fence, or a visitor gets hurt by equipment left in a walkway, GL is what pays the claim. That protects your business and your client relationship. Without it, the liability lands on you.

The Insurance Information Institute's overview of commercial general liability insurance explains that these policies are built to cover bodily injury and property damage tied to a business's operations or completed work. That's the core exposure every contracting business carries on every job.

We shop GL across multiple carriers and set your limits around the work you actually do, not a generic minimum.

Commercial Auto: Your Personal Policy Won't Cover the Work Truck

Commercial auto insurance covers accidents involving your work vehicles, and it's a separate policy from personal auto.

If a work truck backs into a mailbox, damages a driveway, or gets in an accident on a supply run, your personal auto policy typically won't respond, because the vehicle was being used for business. Contractors who assume their personal policy covers the work truck often find out otherwise when a claim gets denied.

The Insurance Information Institute's look at commercial auto notes that commercial auto claims have become more frequent and more expensive across the industry. That's part of why insurers treat work vehicles as a different risk from personal driving.

Worth Adding: Tools & Equipment and Umbrella Coverage

Neither of these is required. Both cover gaps the four core policies leave open.

Tools and equipment

Tools and equipment insurance covers the cost of replacing stolen or damaged tools and machinery. Losing equipment is one of the most common reasons a project stalls.

Jobsite theft is a real, recurring problem, especially when equipment sits on site overnight or over a weekend. IRMI defines this coverage, often called an equipment floater, as a policy that covers mobile or contractor's equipment wherever it is, since a standard property policy typically won't. The National Insurance Crime Bureau has reported recovery cases tied to organized theft rings targeting heavy equipment, so this isn't a rare risk if you run high-value machinery.

Without it, you may have to pause a job for weeks waiting on replacement equipment, and absorb both the cost and the schedule slip.

Umbrella

An umbrella policy extends your coverage beyond the limits of your underlying liability policy. It matters more as your projects get bigger and more valuable.

Standard limits may not stretch far enough on larger additions, custom builds, or high-value ADU projects, where the scope often outgrows what your policy was originally sized for. The Insurance Information Institute explains what an umbrella policy covers: it picks up where your underlying policy's limits end, which is exactly what a severe construction claim can require.

Why Coverage Gaps Put More Than One Job at Risk

A signed contract doesn't protect your business on its own. The protection comes from what's backing it.

Being underinsured doesn't just risk a bad outcome on one job. It can mean a lawsuit that outlasts the business, a suspended license, or a bond claim that makes it harder to get bonded again. Contractors who are fully covered hand those claims to a policy. Contractors who aren't carry that exposure themselves, often without realizing it until a claim shows up.

How to Review Your Own Coverage

A certificate that was accurate a year ago doesn't prove you're covered today. Growth, new equipment, and new crew members all change what your policies should cover. Reviewing your limits and exclusions with an agent, instead of assuming the policy still fits, is what keeps a claim from outrunning your coverage.

A few things worth checking regularly:

• Your limits still match the size of your current projects, not what made sense when you started.
• Your bond status is current. Check it directly with the CSLB.
• Your coverage has kept up with your crew size and vehicle count.
• Your certificates get updated before they lapse, not after a client asks for one.

What Proper Coverage Adds to a Bid

Carrying full coverage is usually a small slice of overall project cost. Insurance transfers risk; it isn't a major line item. Underbidding a job by skipping coverage doesn't lower your risk. It just moves it from the insurer back onto you.

When you check your coverage against your bid pricing:

• Account for all six coverages before you price a job, not after.
• Skipping umbrella or tools and equipment coverage to look competitive on price creates exposure that outweighs the savings.
• The cost difference between full and minimal coverage is usually small next to total project revenue.
• The cost of a single uninsured claim rarely is.

The Bottom Line

Insurance isn't overhead to cut. It's what decides whether one bad day stays a manageable claim or turns into a threat to the whole business. Review all six of these regularly, not just when a GC asks for a certificate, and you protect your crew and your license at the same time.

Frequently asked questions

How do I know if my current coverage is enough for a larger project?

Review your policy limits against the project's total value and risk with your agent before you bid. Don't assume your existing coverage automatically scales up with a bigger job.

What's the difference between a contractor bond and general liability insurance?

The bond guarantees you'll follow licensing law and your contract terms. General liability covers accidents and damage that happen during the work itself. They protect against different risks, and one doesn't replace the other.

Am I liable if a crew member is injured and I don't have Workers Comp?

Yes. Without active Workers Comp, your business is directly exposed to the medical costs and potential legal action from the injured worker, with no policy to absorb the claim.
