Frequently Asked Questions

What insurance should I require from a general contractor's subcontractors?
Every subcontractor should carry their own GL ($1M/$2M minimum), workers' compensation (statutory limits), and commercial auto ($1M CSL). The GC should collect and maintain COIs from all subs before they begin work. Do not rely solely on the GC's policy to cover subcontractor claims — if a sub is uninsured, the claim may flow up to the GC's policy, depleting coverage available for other claims.
What is a per-project aggregate endorsement and when do I need it?
A per-project aggregate endorsement ensures that the GC's full aggregate limit applies separately to each project, rather than being shared across all projects the GC is working on simultaneously. Without this endorsement, claims on other projects could deplete the aggregate limit available for your project. Require this endorsement whenever the GC is working on multiple projects concurrently.
How do I protect against construction defect claims after the project is done?
Require the GC to maintain completed operations coverage for a minimum of 3–5 years after project completion (10 years in states with longer statutes of repose). Verify that your additional insured status extends to completed operations via CG 20 37. Include contractual indemnification provisions and a requirement that the GC notify you if completed operations coverage is cancelled or non-renewed.
Should I require the GC to carry professional liability insurance?
Yes, if the GC is providing any design-build services, construction management, or project management consulting. Standard general liability policies exclude professional services — meaning design errors, specification mistakes, or project management failures would not be covered. A $1M professional liability (E&O) policy is the minimum for most commercial projects.
Do general contractors in Illinois need a license?
No statewide GC license, but City of Chicago requires a General Contractor license through Buildings Department. Must show $500K+ insurance. Most collar counties require local licensing.
What happens if my general contractors's insurance expires in Illinois?
In Illinois, you as the property manager could be held liable for injuries or damages caused by an uninsured general contractors on your property. Illinois courts have consistently ruled that property owners have a duty to verify contractor insurance before allowing work to begin.
