What Does General Contractor Insurance Cost in Missouri?
Most Missouri GCs land in the same national benchmark range as other states, since Missouri doesn't publish its own separate GC-specific loss-cost data. The table below is a national benchmark, not a quote; your actual premium depends on payroll, subcontractor volume, and project size, and a GC layering in a performance bond or SDI program on top of the figures below should expect that separate cost on top of the GL/workers' comp premium.
| Business Size | General Liability (Monthly) | Workers' Comp (Monthly) |
|---|---|---|
| Solo / 1-2 employees | $65 – $110 | $90 – $150 |
| 3-9 employees, subs on most jobs | $140 – $260 | $220 – $420 |
| 10+ employees, multiple concurrent projects | $300+ | $500+ |
What a Missouri General Contractor Policy Should Include
- ✓General Liability, for third-party property damage and injury claims
- ✓Workers' Compensation, required at one employee under RSMo § 287.030
- ✓SDI or a Performance Bond, for subcontractor non-completion risk
- ✓Commercial Umbrella, for claims that exceed your GL limits
Does Missouri Require a General Contractor License?
No. Missouri has no statewide general contractor license. Licensing runs municipality by municipality, and none recognize another city's registration. Certificate of insurance requirements attached to each registration can also differ by city, so a COI that satisfies one metro isn't guaranteed to satisfy the next one's building department.
A GC working all four metros carries four separate compliance obligations, not one, and none of those municipal registrations include the liability coverage a GC actually needs once subcontractors are involved.
Is Workers' Compensation Required for Missouri General Contractors?
Yes, at one employee. RSMo § 287.030 sets construction's workers' comp threshold at just one employee, compared to the five-employee threshold that applies to most other Missouri industries. The legislature treats construction as inherently higher-risk, and a GC's own crew is only part of that exposure, since subcontractor crews on the same job site add liability a GC's own workers' comp policy doesn't touch. The same statute counts family members within the third degree of kinship toward that employee count, so a small family-run GC operation can't assume it stays under the threshold just because payroll looks informal.
What's the Real Difference Between a Performance Bond and Subcontractor Default Insurance?
They guarantee the same failure through two different structures. A Missouri GC coordinating more than a handful of subs per project usually needs to actively choose between the two rather than default to either.
Performance Bond
- Three-party guarantee (owner, GC, surety)
- Owner can claim directly, no deductible
- Surety expects GC reimbursement afterward
- Typically 0.5% to 3% of contract value
Subcontractor Default Insurance
- Two-party policy (GC and insurer only)
- Real deductible, no direct owner claim
- Faster claims handling than a bond
- Typically 0.35% to 1.35% of project cost
How Does Missouri's Mechanics Lien Law Affect a GC's Coverage?
It sets a hard filing clock that shapes payment-dispute risk. RSMo Chapter 429 gives contractors and subcontractors a six-month window to file a mechanics lien after work stops, and RSMo § 429.012 requires a separate Notice of Rights on residential jobs. Because the lien attaches to the property itself, an owner who already paid the GC in full can still face a subcontractor's lien if the GC never paid that sub, which is exactly the kind of payment-chain exposure a performance bond or SDI policy is built to absorb.
