Contractors face some of the highest liability exposure of any small business category. A single job site accident, a stolen tool trailer, or a fire in a building under renovation can trigger six-figure losses. Learn what insurance every contractor needs, what it costs, and how bonding differs from insurance.
Unlike many small businesses that can get by with a BOP and workers' comp, contractors typically need a layered insurance program because they work on other people's property, employ workers in physically dangerous conditions, operate heavy vehicles and equipment, and face unique project-based risks that change from job to job.
General Liability
RequiredMandated by most GCs, project owners, and municipalities as a condition of work
Workers' Compensation
RequiredLegally required in most states; construction is among the highest-risk industries
Commercial Auto
RequiredTrucks, vans, and trailers used for work need commercial (not personal) coverage
Tools & Equipment (Inland Marine)
EssentialStandard property won't cover tools stolen from a job site or work vehicle
Builders Risk
Project-BasedRequired when contractor has an insurable interest in the structure under construction
Umbrella / Excess Liability
RecommendedExtra protection above GL limits; required by many large commercial clients
Contractor's Pollution Liability
Trade-SpecificRequired for HVAC, plumbers, environmental remediation, roofing with chemicals
Surety Bond
Often RequiredRequired by many contracts and state licensing boards; different from insurance
Contractor general liability insurance functions similarly to other GL policies — it covers third-party bodily injury and property damage claims — but several provisions are especially important for contractors.
Covers claims arising after a job is finished. If you complete a roofing project and the roof leaks six months later causing interior damage, completed operations coverage pays the claim. This can trigger years after work is done — which is why it's critical to maintain continuous GL coverage even between projects.
Nearly every general contractor and project owner will require subcontractors to provide an additional insured certificate before starting work. Your policy must be able to accommodate this. A blanket additional insured endorsement covers all required parties automatically — more efficient than naming each one individually.
Standard GL policies exclude property in your "care, custody, or control." If a client's property is in your possession and you damage it, your GL may not cover the claim. Contractors need to verify whether their policy includes an exception to this exclusion, or add a separate bailee/contractor's liability coverage.
| Contractor Type | Est. Annual GL Premium | Notes |
|---|---|---|
| General handyman (solo) | $1,500 – $3,000 | $1M/$2M limits typical |
| Painting contractor | $2,000 – $4,500 | Lead paint work increases premium |
| Electrician | $3,000 – $7,500 | High-risk classification |
| Plumber | $2,500 – $6,000 | Water damage risk |
| HVAC contractor | $3,000 – $7,000 | Refrigerant handling adds risk |
| Roofer | $8,000 – $20,000+ | Highest-risk contractor category |
| General contractor (residential) | $5,000 – $15,000 | Varies widely by revenue |
| General contractor (commercial) | $10,000 – $40,000+ | $2M/$4M+ limits often required |
Your commercial property policy covers equipment stored at a fixed location (your shop or warehouse). But what about equipment at job sites, in your truck, or in transit? That's where inland marine insurance — specifically a tools and equipment policy — provides protection.
ℹ Why It's Called 'Inland Marine'
For heavy equipment — excavators, skid steers, cranes, bulldozers — a contractor's equipment floater provides broader coverage than a standard tools policy. Coverage is typically written on an "open perils" (all-risk) basis and can include equipment in transit, at job sites, or in storage. Equipment values must be accurately reported — under-insuring can result in co-insurance penalties.
💡 Maintain an Equipment Inventory
Construction is consistently one of the highest-risk industries for workers' compensation claims. Falls from heights, struck-by incidents, electrocutions, and caught-in/between equipment accidents are the "Fatal Four" in construction — and each generates significant workers' comp costs.
⚠ Subcontractors Do Not Eliminate Your Workers' Comp Exposure
Builders risk (course of construction) insurance covers structures under construction against damage from fire, wind, lightning, vandalism, and theft. The policy typically covers the structure itself, materials on-site, materials in transit, and sometimes soft costs (architectural fees, permits, loan interest) caused by construction delays from a covered loss.
Who Buys It
Project owner, GC, or developer — per contract. Confirm before project starts.
Typical Limit
Completed project value. Update coverage if scope changes significantly mid-project.
Policy Duration
Tied to construction period. Extensions available if project is delayed.
Common contractor bonds include: License & Permit Bonds (required by state licensing boards), Performance Bonds (guarantees project completion), and Payment Bonds (guarantees payment to subs and suppliers). Larger commercial projects often require both a performance and payment bond simultaneously.
Most contractors need: general liability insurance (required by GCs and project owners), workers' compensation (required in most states), commercial auto (for trucks and work vehicles), tools and equipment / inland marine insurance, and builders risk insurance for any projects where they're the named insured or have a financial interest. Specialty contractors (electricians, plumbers, HVAC) may also need pollution liability. Larger contractors may need umbrella/excess liability on top of their primary GL.
Most general contractors require subcontractors to carry at minimum $1M per occurrence / $2M aggregate, but $2M/$4M is increasingly common for mid-to-large commercial projects. Some municipal contracts, federal work, or large commercial GCs require $5M+ or an umbrella policy on top. Always review your specific contract requirements before purchasing — buying too little means you can't be added as an additional insured or bidding for larger projects.
Inland marine insurance covers movable property — tools, equipment, materials — that travel with you to job sites. Standard commercial property insurance only covers property at a fixed, scheduled location. If your tools are stolen from a job site, your work truck, or a storage unit, a standard property policy won't cover it. Inland marine (tools & equipment) coverage fills this gap and typically covers equipment on- and off-premises, in transit, and at temporary job sites.
Builders risk insurance (also called course of construction insurance) covers a building or structure while it's being built or renovated. It protects against damage from fire, wind, theft, vandalism, and some weather events during the construction period. Who purchases it depends on the contract: general contractors often buy it for their projects, but some project owners purchase it directly. If you're a GC responsible for the project, you should either purchase builders risk or verify it's in place. Subs typically don't buy it, but should verify the GC's policy names them.
Insurance protects you (and your clients) if you accidentally cause harm — a covered claim is paid by your insurer. A surety bond is a financial guarantee made to a third party (your client or project owner) that you will fulfill your contractual obligations. If you fail to complete a job or cause financial harm through dishonesty, the surety company pays the claimant and then seeks reimbursement from you. Being bonded means your clients have financial recourse if you breach a contract or steal from them. Being insured means your clients have protection if you accidentally damage their property or injure someone. Most contractors need both.
