Illinois General Contractor Insurance
Illinois has no statewide GC license — Chicago's tiered Class A-E system covers unlimited-value work at the top tier, but any general contractor coordinating subcontractors here still carries layered liability the local license alone doesn't address.

Why Illinois General Contractors Need Different Coverage Than a Single Trade
A general contractor's real exposure isn't in the work performed directly — it's in the work performed by everyone under contract to you. If a sub's work fails inspection or triggers a claim, the liability lands on the GC holding the prime contract.
Because Illinois has no statewide license, your registration depends on your municipality — Chicago's tiered Class A-E system (unlimited value at Class A, capped at $500,000 for Class E) is the clearest example, but a GC coordinating subcontractors across multiple Illinois cities may need separate registration in each.
Illinois Licensing, Compliance & Requirements for General Contractors
Illinois has no statewide general contractor license. Licensing is local: Chicago uses a tiered Class A-E contractor licensing system based on project value, from unlimited-value Class A ($2,000 fee) down to $500,000-capped Class E ($300 fee).
Workers' comp is mandatory from your first employee, with no small-employer exemption. Illinois has no state OSHA plan for private employers. Illinois' Home Repair and Remodeling Act requires a written contract with specific disclosures for any home repair job over $1,000, relevant to a GC's contracts covering multiple subcontracted trades.
- No statewide GC license — licensing runs through home-rule municipalities like Chicago
- Chicago's tiered Class A-E licensing system based on project-value ceiling
- Workers' comp mandatory from employee one, no small-employer exemption
- Federal OSHA jurisdiction applies statewide
- Home Repair and Remodeling Act requires a written contract with disclosures over $1,000
- Illinois Consumer Fraud Act exposure for violations of the Home Repair Act's disclosure rules
Core Coverages Built Around Managing Subcontractors
A general contractor’s program looks different from a single-trade policy because the exposure is different — you’re insuring the coordination of a job, not just one trade’s labor.
- General liability sized for full project value, not one trade's scope
- Subcontractor default coverage for a sub that can't finish or fails inspection
- Builder's risk for the structure itself during active construction
- Certificate-of-insurance tracking & additional-insured management across every sub on the job
- Workers' compensation, mandatory from your very first employee
- Umbrella liability sized for total project exposure, not per-trade severity

- Which Chicago license class (or other municipality's tier) you hold
- Total annual subcontract volume, since GC exposure scales with sub activity
- Whether you carry subcontractor default coverage separately from general liability
- Payroll and crew size, since workers' comp applies from employee one
- Claims history, including any prior subcontractor-default or construction-defect claims
- Whether your contracts meet Home Repair and Remodeling Act disclosure requirements
