General contractors need a minimum of five core coverages: commercial general liability (CGL), workers' compensation, commercial auto, builder's risk, and umbrella/excess liability. A well-structured program costs most GCs between $8,000 and $35,000 per year depending on payroll, revenue, trade mix, and claims history. Who this is for: Licensed general contractors, construction managers, and residential or commercial builders seeking a complete insurance program.
TL;DR — Key Takeaways
- CGL is the foundation: Most project owners and municipalities require at least $1M per occurrence / $2M aggregate before a GC can pull a permit or sign a subcontract.
- Workers' comp is legally required in nearly every state once you have employees, and many states extend coverage requirements to sole proprietors on certain job types [verify state].
- Builder's risk covers the project itself — your CGL does not pay for damage to the structure under construction.
- Your experience modification rate (EMR) directly controls your workers' comp premium; an EMR above 1.0 can disqualify you from public bids.
- Cost drivers are payroll-based, not just revenue-based — accurate payroll classification (NCCI class codes) is the single fastest way to avoid audit surprises.
What Coverages Do General Contractors Actually Need?
A complete GC insurance program typically includes the following policies. Each covers a distinct exposure — gaps between them are where claims fall through.
| Coverage | What It Covers | Typical Limits | Who Requires It |
|---|---|---|---|
| Commercial General Liability (CGL) | Third-party bodily injury, property damage, personal/advertising injury | $1M/$2M minimum; $2M/$4M common on larger jobs | Project owners, lenders, municipalities |
| Workers' Compensation | Employee on-the-job injury, illness, death; employer's liability | Statutory (no cap in most states); Employer's Liability $500K–$1M | Required by state law |
| Commercial Auto | Owned, hired, and non-owned vehicles | $1M CSL standard; $2M+ on large fleets | State DMV; project owners |
| Builder's Risk | Physical loss to the structure under construction, materials in transit | Usually 100% of completed value | Lenders; project owners |
| Umbrella / Excess Liability | Excess limits over CGL, auto, and employer's liability | $2M–$10M common; mega-projects may require $25M+ | Project owners; bonding companies |
| Inland Marine / Equipment Floater | Owned and rented tools, equipment, and machinery | Scheduled or blanket; up to replacement cost | Leasing companies; internal risk mgmt |
| Professional Liability (E&O) | Design-build or CM-at-risk errors and omissions | $1M/$2M minimum when design is in scope | Design-build contracts |
Coverage note: A standard CGL policy is written on an occurrence basis — the policy in effect at the time of the occurrence pays the claim, even if the claim is filed years later. This matters for completed-operations coverage, which protects you after project handover.
How Much Does General Contractors Insurance Cost?
Premium for a GC program is driven primarily by payroll (workers' comp) and revenue (CGL). Below are realistic annual premium ranges by contractor size and trade mix as of 2025–2026 market conditions. These are illustrative ranges, not guarantees — your actual premium depends on carrier underwriting, state, EMR, and claims history.
| Contractor Profile | Est. Annual Revenue | Workers' Comp | CGL | Auto + Umbrella | Total Est. Range |
|---|---|---|---|---|---|
| Solo GC / owner-operator (no employees) | Under $500K | $2,000–$5,000 | $1,500–$3,000 | $1,500–$3,000 | $5,000–$11,000 |
| Small residential GC (5–15 employees) | $500K–$2M | $8,000–$20,000 | $3,000–$6,000 | $3,000–$6,000 | $14,000–$32,000 |
| Mid-size commercial GC (15–50 employees) | $2M–$10M | $20,000–$60,000 | $6,000–$15,000 | $5,000–$12,000 | $31,000–$87,000 |
| Large GC / CM-at-risk (50+ employees) | $10M+ | $60,000–$200,000+ | $12,000–$40,000+ | $10,000–$30,000+ | $82,000–$270,000+ |
Key cost variables: - EMR (experience mod): An EMR of 0.85 saves roughly 15% on workers' comp; an EMR of 1.25 adds 25%. - Trade mix: Roofing, demolition, and concrete work carry higher class-code rates than finish carpentry or painting. - Subcontractor controls: If you use uninsured subs, carriers will often charge your CGL as if those subs are direct employees. - Claims history: One large GL claim can trigger a surcharge for three to five policy years.
What Does CGL Cover — and What Does It Exclude?
CGL is the most misunderstood policy in construction. It covers third-party losses — meaning someone other than you or your employee gets hurt or their property is damaged. It does not cover:
- Your own work product: If your crew installs faulty framing and the wall has to be torn out, CGL does not pay for the repair to your own work. (This is the "your work" exclusion — coverage for completed operations only applies to resulting damage to other property.)
- Damage to property in your care, custody, or control: The structure you are actively working on is typically excluded until turned over.
- Intentional acts, pollution (without a separate contractor pollution liability endorsement), and professional design errors.
- Employee injuries: Those go to workers' comp.
Subcontractor extension: Most CGL policies contain a blanket additional insured endorsement (often ISO CG 20 10 and CG 20 37) that automatically adds project owners, developers, and other upstream parties as additional insureds for ongoing and completed operations. Confirm your policy includes both forms — omitting CG 20 37 leaves completed-operations coverage gaps.
How to Get General Contractors Insurance in 5 Steps
- Compile your business data. Gather: prior 3 years of loss runs, current payroll by job class, gross revenue, subcontractor spend (with certificates), vehicle schedules, and any owner-controlled insurance program (OCIP) or wrap policy exclusions from your project roster.
- Identify required limits. Review your highest-value active contract. Match your CGL and umbrella limits to the highest contractual requirement — it is far cheaper to buy the right limit upfront than to find a gap after a claim.
- Obtain certificates of insurance from all subs before work starts. Your carrier will audit subcontractor COIs. Uninsured sub spend is often added back to your payroll for premium calculation at audit time.
- Work with an independent agent who can market to multiple admitted and E&S carriers. The admitted market (Liberty Mutual, Travelers, Zurich, Cincinnati Financial, etc.) is preferred, but high-hazard trades or poor loss history may require surplus lines markets.
- Schedule a premium audit walkthrough. Workers' comp and CGL policies are often audit-basis — final premium is calculated after the policy year ends based on actual payroll and revenue. Reconcile your payroll codes quarterly to avoid a large audit bill.
Real-World Example: Mid-Size Residential GC in Texas
Profile: A Texas-based residential GC with 18 employees, $3.2M in annual revenue, primarily single-family new construction and light commercial tenant improvement. EMR of 0.92 (slightly better than average).
Illustrative program (approximate annual premiums):
- Workers' Comp (carpentry/framing, NCCI class 5645): ~$28,000
- CGL ($2M/$4M, including completed ops): ~$9,500
- Commercial Auto (4 owned trucks, hired/non-owned): ~$7,200
- Builder's Risk (blanket, rolling 12-month): ~$4,800
- Umbrella ($5M excess over CGL/auto): ~$6,500
- Inland Marine / equipment floater: ~$2,400
Total estimated program: ~$58,400/year
At audit, if actual payroll ran 8% over estimate, the GC would owe a workers' comp audit bill of roughly $2,200. Because they track payroll monthly, this is expected and budgeted — not a surprise.
This is an illustrative example only. Actual premiums vary by carrier, territory, loss history, and underwriting conditions.
Frequently Asked Questions
Q: Is general liability insurance required by law for general contractors? A: CGL is not typically mandated by state statute, but it is effectively required in practice. State and municipal licensing boards in most states require proof of liability insurance to issue or renew a contractor's license. Nearly every commercial project owner, lender, and landlord requires it contractually before work starts. In this sense, operating without CGL is not a viable business option for most GCs.
Q: Does workers' compensation cover subcontractors? A: No — workers' comp covers your W-2 employees, not independent contractors or subcontractors. However, if a sub you hire does not carry their own workers' comp, most states allow injured sub workers to claim against your policy. This is why requiring valid COIs from every sub before they step on your jobsite is critical — and why carriers charge you for uninsured sub spend at audit.
Q: What is builder's risk insurance and do I need it? A: Builder's risk (also called course-of-construction insurance) covers physical loss or damage to a structure while it is being built — fire, wind, hail, vandalism, and often theft of materials. Your CGL does not cover the building under construction. Either you, the project owner, or the lender typically purchases builder's risk; the contract language determines who is responsible. If you are the GC, confirm in writing who holds the policy before you start.
Q: What limits do I need for a commercial project? A: Most commercial owners, REITs, and national retailers require at minimum $1M per occurrence / $2M aggregate for CGL, plus a $5M umbrella, with the owner named as an additional insured. Public-sector projects (schools, municipalities) often require $2M/$4M CGL plus a $10M umbrella. Always read the contract insurance exhibit — it controls, not a generic rule of thumb.
Q: How does my experience modification rate (EMR) affect my premium? A: Your EMR is a multiplier calculated by NCCI (or a state-specific rating bureau) based on your actual loss history versus expected losses for your trade. An EMR of 1.0 is average. An EMR of 0.85 means you pay 15% less than the base workers' comp rate; an EMR of 1.30 means you pay 30% more. Many public agencies and large GCs will not award contracts to subs with an EMR above 1.0 or 1.25. Reducing your EMR is a multi-year process driven by safety programs, return-to-work programs, and timely claims reporting.
Q: What is an additional insured endorsement and when do I need to provide one? A: An additional insured (AI) endorsement adds another party — typically the project owner, developer, or upstream GC — to your CGL policy so they receive coverage for claims arising from your operations. It is different from a certificate of insurance: a COI is just evidence of coverage; an AI endorsement actually extends coverage. Most commercial contracts require you to add the owner as an AI for both ongoing operations (ISO CG 20 10) and completed operations (ISO CG 20 37). Confirm your policy automatically grants blanket AI status — otherwise every project requires a separate endorsement request.
Q: Do I need contractor pollution liability (CPL)? A: Standard CGL policies contain a pollution exclusion that is broad enough to exclude many construction-related exposures — fuel spills, disturbed asbestos or lead paint, silica dust, mold discovered during renovation, and excavation-related contamination. If you work on older buildings, do any earthwork, or handle hazardous materials, a standalone contractor pollution liability policy is worth evaluating. CPL premiums typically start around $1,500–$4,000/year for small to mid-size GCs.
Q: Can I get all my coverages from one carrier? A: Yes, many carriers offer a construction package policy (CPP) that bundles CGL, inland marine, commercial auto, and sometimes umbrella in one policy, which can simplify billing and reduce gaps. Workers' comp is typically separate. Builder's risk is almost always separate. For large GCs with complex programs or difficult loss history, placing individual lines with specialized carriers often produces better coverage terms than a monoline package.
