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.
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.
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' 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 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 (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.
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.
The most damaging exposures are usually invisible on a certificate. Watch for these:
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.
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.
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.
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.
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.
General contractor coverage is easy to buy and hard to get right — the difference lives in the endorsements, subcontractor terms, and limits a certificate never shows.
