General Contractor Insurance

What insurance does a general contractor need?

A general contractor (GC) manages entire projects: hiring subcontractors, ordering materials and taking responsibility for the job site. That responsibility is why GCs need broader insurance than most small businesses.

General liability is the foundation. For contractors, two parts matter most:

• Ongoing operations: injuries and damage while the job is in progress, such as a passer-by hit by falling debris.
• Completed operations: claims that arrive after the job is finished, such as a deck that collapses a year later. Check that your policy includes completed operations and how long it applies.

Workers' compensation covers your employees. Construction carries some of the highest workers' comp rates of any industry, and several states require construction businesses to carry it with fewer employees than other industries. For example, Florida, Missouri, New Mexico and Tennessee apply lower thresholds to construction. See workers' comp requirements by state.

Commercial auto, tools and equipment, builder's risk and a commercial umbrella round out a typical GC insurance program.

How much does general contractor insurance cost?

According to Insureon's 2026 data from 100,000 small-business customers, construction businesses pay a median of:

Across all industries, a commercial umbrella policy has a median of $86 a month. A GC running large commercial projects with many employees will pay far more than these medians, because premiums are based on:

• Revenue and payroll (general liability is often rated on revenue or subcontracted costs)
• Type of work: residential remodeling, new homes or commercial
• Subcontractor use and whether subs carry their own insurance
• Claims history and safety record
• Limits required by your contracts
• State and location of your projects

Subcontractors and certificates of insurance

Your insurer will look closely at how you manage subcontractors. If an uninsured subcontractor causes damage or gets hurt, the claim can land on your policy, and an audit may add the uninsured sub's costs to your premium.

Good practice:

• Collect a certificate of insurance (COI) from every subcontractor before work starts, and track expiration dates.
• Require subs to name you as an additional insured on their general liability.
• Ask for workers' comp certificates or valid exemptions.
• Use written subcontract agreements with indemnity and insurance clauses reviewed by an attorney.

Example claims (illustrative)

• Example: A drywall subcontractor leaves a tool on a stairway and the homeowner falls. Because the sub's insurance had lapsed, the homeowner's claim goes to the GC's general liability.
• Example: Eighteen months after you finish a remodel, a beam you installed sags and damages the floor above. Completed operations coverage responds.
• Example: A framer on your crew is injured in a fall. Workers' compensation pays medical bills and lost wages.
• Example: Thieves take a generator and saws from a locked job-site trailer. Tools and equipment coverage helps you replace them.

Is insurance required for a general contractor?

Usually, yes, in some form. Many states and cities require general contractors to be licensed, and licensing boards often require proof of general liability, workers' comp, a surety bond, or a combination. The exact limits vary, so check with your state contractor licensing board. Building permits, project owners, lenders and public projects add their own requirements.

Bonds vs. insurance: a license or performance bond guarantees your obligations to the state or the project owner, and you must repay any claim the surety pays. Insurance pays covered claims on your behalf. Most GCs need both.

Common contract insurance clauses explained

Construction contracts often include insurance language that affects what you must buy:

• Additional insured: the project owner or lender is added to your general liability policy.
• Primary and non-contributory: your policy pays first, before the owner's own insurance.
• Waiver of subrogation: your insurer gives up the right to recover from the owner after paying a claim.
• Per-project aggregate: your aggregate limit applies separately to each project instead of being shared across all jobs.

These endorsements usually need to be added to your policy before work begins. Send the insurance section of each contract to your agent and ask them to confirm the policy matches before you sign.

Questions to ask your insurance agent

1. How long does completed operations coverage last after a project ends?
2. Are there exclusions for residential, condo or subsidence work?
3. How will subcontractor costs be treated at audit?
4. Can I get per-project aggregate limits?

How to lower your premium

• Require insurance from every sub and keep certificates on file.
• Run a written safety program and document toolbox talks and training.
• Classify payroll correctly by job type for workers' comp.
• Keep accurate records for year-end audits.
• Secure job sites and equipment to prevent theft.
• Bundle policies and review limits each year with an agent who specializes in construction.
