Essential Insurance Coverages and Common Gaps for General Contractors

Written by Kody Houk | Jul 7, 2026 10:17:05 PM
Quick answer: General contractors need five core coverages — general liability, workers' compensation, commercial auto, builder's risk, and professional liability — usually backed by an excess/umbrella policy. The most common gaps are subcontractor "your work" exclusions, missing additional-insured and contractual-liability terms, and limits too low for the contract.

General contractors carry a risk that no other trade fully shares: you are responsible not only for your own crews, but for the work of every subcontractor on the job. A framing error, a plumber's leak, or a subcontractor who shows up without proper coverage can all land on your policy. That is why "general contractor insurance" is really a program of several policies working together — and why the fine print, not the certificate, decides whether a claim is actually paid.

This guide explains what each coverage does, what a standard policy leaves out, and the specific gaps that catch general contractors off guard.

Key Takeaways

  • A complete GC program rests on five pillars: general liability, workers' compensation, commercial auto, builder's risk, and professional liability — plus an excess/umbrella layer.
  • General liability excludes employee injuries, stolen tools, professional errors, and often your subcontractors' faulty work. Each requires its own solution.
  • The "your work" subcontractor exclusion (ISO form CG 22 94 or a carrier equivalent) can quietly remove coverage for a sub's defective work — a serious exposure for GCs.
  • Requiring subcontractors to name you as an additional insured, and carry limits equal to yours, is one of the most effective risk-transfer tools available.
  • A certificate of insurance proves a policy exists; it does not reveal the exclusions, sublimits, and endorsements that decide a claim.

What Insurance Does a General Contractor Need?

A general contractor needs, at minimum, general liability and workers' compensation. A complete program adds commercial auto, builder's risk, and professional liability, layered under an excess/umbrella policy to reach the total limits most projects require.

General liability (CGL)

Commercial general liability covers third-party bodily injury and property damage — a visitor hurt on site, or damage to an adjacent structure. A properly written policy includes premises/operations, products-completed operations, contractual liability, and personal and advertising injury. For GCs, contractual liability and completed operations matter most, because they back up the indemnity promises you sign and respond to defects that surface after the job closes.

Workers' compensation

Workers' comp pays medical bills and lost wages when an employee is injured, and it is legally required for businesses with employees in nearly every state. General liability explicitly excludes employee injuries, so comp is the only policy that responds. Rates vary widely by trade classification and payroll, and general contractors are frequently held responsible for uninsured subcontractors' injuries — another reason to verify sub coverage.

Commercial auto

Commercial auto covers the trucks that move crews, tools, and materials. Personal auto policies exclude business use, so a work truck insured on a personal policy is effectively uninsured on the job.

Builder's risk

Builder's risk (course-of-construction) covers the structure while it is being built, along with materials on site and often in transit, against fire, wind, theft, and vandalism. It fills a gap that neither general liability nor a finished-building property policy addresses.

Professional liability (contractors E&O)

If you provide design-build services, manage means and methods, or make engineering-adjacent decisions, professional liability responds when a mistake in that professional judgment — not the physical work — causes a client financial loss. Standard general liability does not cover it.

Where General Contractors Get Caught: The Common Gaps

The most damaging exposures are usually invisible on a certificate. Watch for these:

  • The "your work" subcontractor exclusion. Some carriers add an endorsement (ISO CG 22 94 or equivalent) that removes coverage for property damage arising from a subcontractor's work. Because GCs rely heavily on subs, this can gut completed-operations protection.
  • Weak or missing risk transfer from subs. If subcontractors don't name you as an additional insured, carry adequate limits, and provide waivers of subrogation, their claims flow back to your policy and drive up your losses.
  • Contractual liability shortfalls. Your contracts obligate you to indemnify owners and others. If the policy's contractual liability terms don't match those obligations, you may be paying out of pocket for a promise your insurance won't back.
  • Limits that don't meet the contract. Many owner and public agreements require $1M per occurrence and $5M or more in total limits, plus additional-insured and primary-and-noncontributory wording. Thin limits can cost you the job.
  • Faulty workmanship confusion. General liability generally pays for damage your work causes to other property, not the cost to tear out and redo the defective work itself. Knowing that line changes how you bid, warranty, and document a project.

Frequently Asked Questions

What insurance do general contractors need?

At minimum, general liability and workers' compensation. A full program adds commercial auto, builder's risk, and professional liability, backed by an excess/umbrella policy to satisfy contract limit requirements.

Are subcontractors covered under a general contractor's policy?

Not automatically. A subcontractor is only covered under your policy if you extend it through an additional-insured endorsement. Best practice is the reverse: require subs to name you as an additional insured on their own coverage.

Does general liability cover faulty workmanship?

Generally no. General liability covers resulting damage to other property but typically will not pay to redo your own defective work. Some policies also exclude damage arising from subcontractors' work, so the wording matters.

How much does general contractor insurance cost?

Cost depends on payroll, revenue, trade mix, project type, and limits, so a tailored quote is the only accurate answer. A coverage review sizes the right limits without overpaying for coverage you don't need.

Does a certificate of insurance prove I'm fully covered?

No. A certificate confirms that policies exist and shows their limits, but it does not reveal exclusions, sublimits, or endorsements. Only reviewing the actual policy forms shows what is truly covered.
