Contractor Insurance: Coverage, Cost, and How to Buy

Which policies a contracting business actually needs

A residential remodeler with two employees does not carry the same policies as a commercial general contractor running a multi-trade site. The right program depends on the work you perform, the people you employ, the vehicles and equipment you use, and the contracts you sign.

The card grid below connects each common loss target to the policy that addresses it. Some contractors need all of these lines. Others need three or four. The deciding factors are your trade, your workforce, your equipment, and what your customers require.

General liability (GL): the foundation

General liability (GL) covers third-party bodily injury, property damage, and certain personal injury claims. It can fund legal defense as well as covered settlements or judgments, subject to policy terms, limits, and exclusions.

GL is not a warranty for poor work. The important distinction is between damage to the contractor's own work product (generally not covered) and resulting damage to someone else's property (which may be covered). Exact outcomes depend on the policy language, the allegations, and state law.

Workers compensation (WC) and employers liability

Workers compensation (WC) addresses job-related employee injury or illness. Employers liability covers certain employer-liability allegations outside the core statutory benefit. Requirements vary by state, ownership structure, headcount, and construction-specific rules.

A sole owner's exemption does not automatically satisfy a general contractor or project owner. Contract documents may demand evidence of workers comp even when a statutory exemption is available.

Commercial auto and hired and non-owned auto

Commercial auto belongs in the program when vehicles are owned, hired, or used regularly for business. Personal auto policies may exclude or limit business use, especially when a vehicle is titled to the business or used primarily for work.

Hired and non-owned auto can address some liability exposures when the business does not own the vehicle, but it is not the same as physical damage coverage for that vehicle. Separate the exposure review into owned autos, employee-owned autos used for errands, rented vehicles, trailers, and heavy mobile equipment.

Inland marine and builders risk

Tools and equipment insurance (inland marine) can address tools, machinery, and materials in transit, temporarily stored, or used at jobsites. A premises property policy may not follow your tools to the job.

Builders risk is project property coverage, not liability coverage. Responsibility for buying it may sit with the owner, general contractor, or another party under the construction contract. A contractor should not assume the owner's policy protects every tool, temporary structure, or material at every stage.

Professional liability, pollution liability, and umbrella

Professional liability becomes relevant when the contractor performs design, engineering, consulting, or construction management services. Contractors pollution liability (CPL) becomes relevant when work can create or disturb pollutants, including contaminated soil, mold, asbestos, fuel, or chemicals.

An umbrella or excess policy adds limits above scheduled underlying policies. The contractor must check which policies are scheduled and whether the umbrella terms follow the underlying coverage. A contract that requires the customer to be an additional insured on primary and excess layers is not satisfied merely because the contractor owns an umbrella.

What general contractors and clients require before you start work

Contract insurance provisions allocate risk before a loss. They can specify coverage types, limits, form editions, additional insureds, priority of coverage, waivers, carrier qualifications, and how subcontractors must be handled. The correct workflow is to compare the signed contract against the actual policy and endorsements before you mobilize to the jobsite.

Additional insured endorsements: ongoing versus completed operations

An additional insured endorsement extends specified protection under your liability policy to another party. It is different from being a certificate holder. A certificate summarizes coverage but does not rewrite the policy.

Ongoing and completed operations require separate attention. CG 20 10 addresses ongoing operations while CG 20 37 addresses completed operations. Relying on ongoing-operations wording alone can leave later property-damage or injury allegations outside the additional insured grant. The contract may specify editions, and editions are not interchangeable.

Primary and noncontributory wording

Primary and noncontributory wording sets the intended order when more than one policy applies to the same loss. The contractor's policy is intended to pay first and without seeking contribution from another policy that also claims to be primary. Additional insured status alone does not necessarily create that priority. The contract language and policy endorsement must align.

Waiver of subrogation

A waiver of subrogation is the insurer's acknowledgment that it will not pursue recovery from a liable third party after paying a covered loss. This is not the same as additional insured status, and contracts often request both. Waivers can appear in GL, auto, property, and workers comp contexts, with different forms and state constraints. Check them line by line rather than treating the waiver as a single universal endorsement.

Certificates versus endorsements

A certificate of insurance (COI) summarizes your coverage on a standard form. It does not change the policy. When a contract requires additional insured status, the endorsement is the document that actually extends protection. A certificate may reference the endorsement, but it does not prove the endorsement was issued or that its wording satisfies the contract. Always obtain and review the actual endorsement to confirm additional insured status and terms.

How carriers price a contractor insurance account

There is no standard price for contractor insurance. Carriers price each coverage line from different details about your business. The rating factors that matter most depend on the line of coverage.

Rating factors by coverage line

• Workers compensation: payroll amount, class codes for each type of work, experience modification rating, and state.
• General liability: gross receipts, work type, subcontractor cost, claims history, and state.
• Commercial auto: number and type of vehicles, driver records, radius of travel, garaging location, and claims history.
• Inland marine: total replacement value of scheduled tools and equipment, storage location, and theft controls.

Hartford reported an average cost of $69 per month, or about $824 per year, for $1 million of contractor general liability coverage as of February 2026. That is a carrier-reported average across their contractor book, not a quote for your account. Your premium depends on trade, state, payroll, revenue, subcontractor use, claims history, and the limits your contracts require.

For a deeper look at contractor insurance pricing by trade and coverage line, see the contractor insurance cost guide.

Coverage gaps that cost contractors real money

Each gap below follows the same pattern: the contractor had a policy, believed they were covered, and discovered the exclusion or missing endorsement after a loss.

The own-work question

General liability is designed around liability to others. It does not guarantee correction of defective work. The key distinction is between damage to the contractor's own work product (generally not covered) and resulting damage to someone else's property (which may be covered subject to policy terms).

For example, if a plumbing installation fails and water damages the homeowner's finished basement, the damage to the basement may be covered. The cost to remove and replace the failed plumbing itself typically would not be.

Completed-operations lapse

Tools and equipment left uncovered

Inland marine coverage can address mobile equipment, tools, and materials in transit or at job sites. But a low blanket limit or an unscheduled high-value item can produce a severe shortfall even when a policy exists. Schedule high-value items by serial number and confirm the blanket limit covers the total replacement value of everything on the truck and at the jobsite.

Employee injury is not covered by general liability

A common misconception is that GL covers employee injuries. It does not. Employee injuries on the job are covered by workers compensation. If an employee is hurt and you do not carry workers comp, you may face the full cost of medical bills, lost wages, and legal defense.

How subcontractor use and audits change your cost

Carriers and auditors treat uninsured subcontractor cost as your exposure. If a sub does not carry their own workers comp or GL, the carrier may add that sub's labor cost to your premium at audit. Strong documentation can prevent surprises.

What carriers ask about your subcontractors

Underwriters commonly want the percentage of work subcontracted, the types of work delegated, written agreement practices, minimum limits required of subs, and whether you track certificates. Weak documentation leaves the carrier unable to distinguish transferred risk from risk you retained.

How uninsured sub cost gets added at audit

At the end of the policy term, the carrier reconciles your estimated payroll and subcontractor cost against actual records. If a sub cannot produce a valid certificate of insurance (COI) for the period they worked on your project, the carrier may include that sub's cost in your audited premium. The result is an additional premium bill you did not budget for.

For more on how audits work and how to prepare, see the workers comp audit guide.

Keeping payroll separated by class code

Misclassifying a worker or blending high-hazard and low-hazard operations can distort the deposit premium and produce an audit adjustment. The goal is to describe operations accurately enough that the policy is priced for the work being performed. Keep payroll records separated by defensible classifications and retain subcontractor invoices and insurance evidence.

What to have ready when you request quotes

The more detail you provide up front, the more accurate your quotes will be. Carriers ask for business, financial, operations, and loss information. Having it organized before you request quotes saves time and produces better comparisons.

For a full breakdown of what contracts and carriers expect, see the contractor insurance requirements page.

When you compare quotes, normalize more than price. Compare named insureds, described operations, classifications, limits, aggregates, deductibles, additional insured capability, completed-operations coverage, exclusions, subcontractor conditions, audit basis, and the service process for certificates.

Frequently asked questions about contractor insurance

These questions come up often when contractors are shopping for coverage or trying to satisfy a contract requirement.

Do I need insurance to get a contractor license?

Contractor licensing requirements vary by state, locality, and license classification. Some jurisdictions require proof of general liability, workers compensation, or a surety bond before issuing a license. Others have no insurance requirement at all. A surety bond guarantees an obligation to an obligee and is not the same as a liability policy. Check your state or local licensing authority for the exact requirements before you apply.

Does general liability cover my employees?

No. General liability covers third-party bodily injury and property damage claims. Employee injuries on the job are covered by workers compensation. If you have questions about whether you need workers comp, see the do I need workers comp insurance guide.

What is the difference between a certificate and an endorsement?

A certificate of insurance summarizes your coverage on a standard form. It does not change the policy. An endorsement is an amendment to the policy itself. When a contract requires additional insured status, the endorsement is the document that actually extends protection. A certificate may reference the endorsement, but it does not prove the endorsement was issued or that its wording satisfies the contract. Always obtain and review the actual endorsement to confirm additional insured status and terms.

How much does contractor insurance cost per month?

There is no single answer. Hartford reported an average of about $69 per month for contractor general liability with $1 million limits. Workers comp, auto, inland marine, and umbrella each add to the total. Your premium depends on trade, state, payroll, revenue, vehicles, subcontractor use, claims history, and the limits your contracts require.

Can I get contractor insurance if I have been declined?

A decline from one carrier does not mean every carrier will decline. Surplus lines and specialty markets exist for harder-to-place accounts. A marketplace that compares multiple carrier options can help find programs that accept your trade, loss history, or project type.

Do independent contractors need workers compensation?

It depends on the state and the contract. Some states exempt sole proprietors with no employees. But a general contractor or project owner may still require proof of workers comp before allowing you on site. For more detail, see the independent contractor workers comp insurance guide.
