Key Takeaways
- Property owners can be held liable as statutory employer for uninsured workers.
- Verify license and insurance before contract signing—fraudulent certificates exist.
- Additional insured endorsement names property owner on contractor policy.
- Subcontractor insurance must be verified—GC coverage may not extend to subs.
Contractor licensing and insurance requirements protect property owners. Using unlicensed or uninsured contractors creates substantial legal and financial exposure for investors.
Licensing Requirements
State licensing: most states require GC license (some by trade). Verify: active status, proper classification for work scope, bond amount, complaint history. State license lookup: typically available online through contractor licensing board. Municipal licensing: many cities require separate business license and registration. Specialty licenses: electrical, plumbing, HVAC typically require separate trade licenses.
Required Insurance
General liability: minimum $1M/$2M recommended. Workers compensation: required in most states for any employees. Auto liability: for contractor vehicles. Umbrella/excess: additional coverage above primary limits. Verify: active policy with adequate limits, additional insured endorsement naming property owner and lender, waiver of subrogation if required by lender.
| Coverage Type | Minimum Recommended | Verify |
|---|---|---|
| General Liability | $1M per occurrence / $2M aggregate | Certificate of Insurance + Additional Insured |
| Workers Comp | State statutory limits | Certificate + Waiver of Subrogation |
| Auto Liability | $1M combined single limit | Certificate |
| Umbrella | $1M-$5M | Certificate |

Consequences of Non-Compliance
Using unlicensed contractors: contract may be void/unenforceable, no license bond protection, no licensing board complaint process, potential liability for unlicensed activity. Using uninsured contractors: property owner liable for worker injuries (workers comp), property owner liable for third-party injuries (general liability), lender policy violations. In many states, property owners can be held liable as the "statutory employer" of workers on their property.
Verification Process
Before contract signing: verify license online (state board), request Certificate of Insurance (COI), verify COI directly with insurance company (fraudulent certificates exist), confirm workers comp coverage or exemption documentation, check complaint and disciplinary history. During project: verify insurance renewal if policy expires during project, confirm subcontractors carry proper coverage, monitor for additional crews not covered.
