Contractor insurance — workers comp is the line that actually drives your cost.
Contractor insurance has many moving parts, but workers comp typically dominates the cost. Get the class codes right and the safety record disciplined, and the rest follows.
The short answer
A typical contractor insurance program in 2026 has multiple separate policies:
- Business Owner's Policy (BOP) or commercial package — general liability + property
- Workers compensation — usually the largest line item; class-code-driven
- Commercial auto — for owned vehicles (pickups, vans, trucks, trailers)
- Builder's risk / Course of construction — for the project under construction
- Inland marine / Equipment — for tools and equipment in transit / on-site
- Surety bonds — for bonded projects (government, larger commercial)
- Optional — pollution liability, EPL, cyber, umbrella / excess
The practical carrier shortlist by trade:
- General contractors (residential + commercial) — The Hartford, Travelers, Nationwide, CNA, Zurich, Builders Mutual (specialty), Hiscox (smaller GCs)
- Electrical / plumbing / HVAC — Hartford, Travelers, Liberty Mutual, Nationwide, plus Amerisure and AmTrust (specialty)
- Roofing — More selective. Builders Mutual, AmTrust, USIC are competitive. Some standard markets restrict.
- Heavy construction (concrete / framing) — Travelers, Zurich, CNA, Federated Mutual, Liberty Mutual
- Specialty trades (solar, EV charging, smart-home) — Hiscox, Next Insurance for flexibility on newer business models
- Small / sole-proprietor — Next Insurance, Insureon (digital broker), Hiscox direct
Specific premium ranges vary widely by trade, class code, prior losses, and geography — get quotes from a construction-specialty broker if you have employees and meaningful equipment.
What contractor insurance actually covers
A typical contractor insurance program in 2026 includes:
1. General Liability (GL) — third-party bodily injury and property damage from your work. Damage to customer property during the job, third-party injury at the job site.
2. Workers compensation — covers employee work-related injuries. Required by state law in most states. Construction class codes are among the highest-rated; sub-contractor classifications matter.
3. Commercial property insurance — your office / shop / warehouse, owned tools, materials inventory.
4. Commercial auto — your owned vehicles. Hired and non-owned auto endorsement covers subcontractor or employee personal-vehicle use during work.
5. Builder's risk / Course of construction — covers the project under construction (the building itself, not your work product). Project-specific or annual blanket policy. Owner sometimes provides; contractor sometimes provides; depends on contract.
6. Inland marine / Equipment insurance — covers tools, equipment, and materials in transit or stored off-site. Equipment floater for valuable equipment.
7. Pollution liability — covers claims from accidental pollution releases (relevant for trades involving solvents, fuels, hazmat). Often excluded from GL.
8. Surety bonds — required for many bonded projects. Performance bonds, payment bonds, bid bonds, license bonds (state-required for licensure).
9. EPL, cyber, umbrella — optional but increasingly relevant.
Contractor-specific insurance considerations
Five things contractors should weigh:
1. Workers comp class codes. Construction class codes are among the most-impactful in any industry. A misclassified class code can mean overpaying significantly. Verify your class codes annually; specialty trades (roofing, electrical, framing) have specific codes that should match the actual work.
2. Sub-contractor verification (Certificate of Insurance). When you hire subs, get COIs with you named as additional insured. Without proper COI tracking, your GL and workers comp can be tagged with claims that should belong to the sub. This is one of the most-common contractor insurance mistakes.
3. Hired and non-owned auto for sub-vehicle use. When subs drive their own vehicles to your job site, the liability can attach to your auto policy if not properly endorsed. Verify hired and non-owned auto coverage matches your sub-use patterns.
4. Equipment and inland marine separately. GL and commercial property typically exclude equipment-in-transit and equipment-on-job-site. Inland marine (equipment floater) covers it. For contractors with valuable equipment, this is critical.
5. Pollution liability for trades with chemical / fuel / hazmat exposure. Trades involving solvents, paints, fuels, asbestos, lead paint, mold remediation — pollution liability is often required by contract. GL excludes pollution; you need a separate endorsement or policy.
What to do — in order
- Inventory your insurance requirements. State workers-comp requirements, license-bond requirements, contractual insurance requirements (additional-insured status, specific limits), bonded-project performance-bond requirements.
- Quote at least 3 carriers including a construction specialist. Hartford / Travelers / Nationwide for broad appetite; Builders Mutual or Amerisure for construction-specialty depth; an independent agent or construction-specialty broker for full market access.
- Use an independent agent or construction-specialty broker. Direct-from-carrier digital is fine for sole-proprietor or very small contractors; for crews with employees and meaningful equipment, an agent / broker provides multi-carrier visibility and surety-bond access.
- Match limits to contract requirements. Many commercial customers and bonded government work require specific GL minimums. Match limits to your actual project mix.
- Don't underinsure equipment. The single most-common contractor-insurance error is undervaluing tools and equipment. Verify equipment / inland marine limits actually replace your fleet.
- Re-quote on each renewal cycle, especially after claims. Workers-comp rates change annually based on your experience modification (e-mod).
Special cases
Subcontractors vs employees (1099 vs W-2). Workers comp typically requires coverage for W-2 employees, sometimes for 1099 contractors depending on state and degree of control. Misclassification is a common audit issue; verify your sub agreements actually establish independent-contractor status under state law.
Bonded work. If you do government, school, or larger commercial work, you'll likely need surety bonds. Surety appetite varies by carrier and contractor history; building a relationship with a surety broker early matters.
Solar / EV / new-construction-tech. Newer trades can be harder to underwrite. Specialty markets (Hiscox, Vouch for tech-adjacent) handle them better than legacy commercial markets.
Restoration / disaster-recovery contractors. Post-disaster restoration work has unique exposures (mold, water damage, asbestos in older buildings, environmental). Specialty markets and pollution liability are typically required.

Frequently asked
How much does contractor insurance cost?
Premium varies dramatically by trade, class code, prior losses, employee count, equipment, and geography. Workers comp is usually the largest line item; class-code-driven. Get quotes from at least 3 carriers including a construction-specialty broker.
Do I really need workers comp if I'm a one-person operation?
Depends on state law and your work mix. Most states allow sole-proprietors to opt out of workers comp on themselves (you self-insure your own injuries). However, many commercial customers require contractors to carry workers comp before they'll let you on the job site — even if state law doesn't require it. Practically, most working contractors carry workers comp regardless of legal requirement.
What's the difference between insurance and a surety bond?
Insurance protects you (the contractor) — pays you for losses. A surety bond protects the project owner — guarantees that you'll perform the contracted work. If you fail to perform, the surety pays the owner and then comes after you for reimbursement. Surety bonds are required for most government and larger commercial work; some state contractor-license requirements also require small license bonds. They're sold separately from insurance, often by the same brokers.
What about COI tracking for my subcontractors?
Critical. Get Certificate of Insurance (COI) from every sub before they start work, with you named as additional insured on their GL and workers comp. Without proper COI, your GL and workers comp policies can absorb claims that should belong to the sub — driving your premium up and potentially exposing you to coverage gaps. COI tracking software (myCOI, EvidenceIQ, others) helps automate this for contractors with meaningful sub volume.
