Contractor insurance requirements in Chicago.
Illinois does not license general contractors at the state level — which makes Chicago's DOB registration, trade-specific licenses, and the Illinois Home Repair and Remodeling Act the actual screen between legitimate and fly-by-night operators. A contractor in Chicago may hold no state-level GC credential yet be fully compliant if they are DOB-registered with active GL and carry the correct trade licenses for the subs they manage. This guide covers what's required at the state, city, and trade levels and how to verify each in under fifteen minutes.
Regulatory framework
Three layers. Illinois state licenses specific trades — plumbers via IDPH, roofers via IDFPR under the Illinois Roofing Industry Licensing Act, but does not license GCs. City of Chicago requires General Contractor registration with the Chicago Department of Buildings for any permit-pulling residential work. DOB registration requires proof of GL (typical $1M per-occurrence minimum for residential, higher for commercial), workers' comp, and a bond. Illinois Home Repair and Remodeling Act (815 ILCS 513) regulates home-repair contracts $1,000+: written contract required, consumer right-to-cancel, mandatory consumer rights brochure distribution.
Cook County and individual suburbs (Evanston, Oak Park, Skokie, Wilmette) have their own contractor registration and insurance requirements that differ from Chicago DOB. Any contractor working across the metro should be verified against each municipality's requirements. The Illinois Workers' Compensation Commission administers mandatory WC under 820 ILCS 305 for any contractor with employees.
Coverage types and 2026 typical limits
General liability: $1M per occurrence / $2M aggregate is the Chicago residential standard; larger commercial projects require $3M-$5M. Annual premium $3,000-$18,000 for typical residential GCs. Workers' compensation: statutory; Illinois construction rates 7-25% of payroll depending on trade. Commercial auto: $500K-$1M per occurrence. Tools & equipment: optional.
Chicago DOB registration bond: varies by license class ($5K-$25K typical). Builder's risk: typically owner-procured for renovations and new construction. Performance bond: not statutorily required for residential; requested by homeowners on $250K+ projects at 1-3% of contract value. Umbrella: $2M-$10M excess; common for contractors handling multi-unit and commercial work.
Four pitfalls Chicago homeowners hit
- Assuming Illinois licenses GCs. Many homeowners ask 'what's this contractor's Illinois state license number?' — and accept vague answers. Illinois doesn't license GCs. The real check is Chicago DOB registration plus trade-specific IDPH/IDFPR licenses for sub-trades. Ask the right question and verify each.
- Missing the 3-business-day cancellation right. Illinois Home Repair and Remodeling Act gives consumers 3 business days to cancel any residential contract over $1,000 signed at the home. Contractors who pressure you to sign and start work immediately are often trying to short-circuit this right. You can always cancel in the 3-day window.
- Hiring an unregistered contractor for permit-pulling work. If the contractor isn't Chicago DOB-registered, they can't legally pull the permit — and a permit pulled in the homeowner's name alone transfers structural code-compliance liability to you. Always require the registered contractor to pull the permit.
- Skipping trade-license verification for subs. The GC may be Chicago-registered but the subs (plumber, electrician, roofer) may not hold the right state-level licenses. Plumbing violations triggered by IDPH-unlicensed subs can result in IDPH stop-work orders and failed final inspections.
5-step verification checklist
- Verify contractor's Chicago DOB registration on chicago.gov/buildings — confirm active and class matches scope.
- For plumbing subs, verify IDPH license; for roofing, verify IDFPR Roofing Contractor license.
- Request ACORD 25 — $1M+ GL, WC, auto, YOU as Certificate Holder; call broker to confirm current.
- Review contract for Home Repair and Remodeling Act compliance: written scope, total cost, 3-day cancellation notice, consumer rights brochure.
- At contract signing: require contractor to pull all permits in their name, 30-day insurance cancellation notice, and right to stop work on coverage lapse.
FAQ
Does Illinois require general contractors to be licensed?
No — at least not at the state level. Illinois does not license general contractors statewide. It DOES license specific trades: plumbers (IDPH), roofers (IDFPR), electricians (via local municipality), and a few others. Chicago adds its own licensing layer: the city requires General Contractors to register with the Chicago Department of Buildings (DOB) for any permit-pulling work, plus specific licenses for plumbers, electricians, and site-safety roles. The lack of state-level GC licensing is why the Chicago DOB registration and insurance verification matters so much — it's the primary screen between legitimate and fly-by-night operators.
What's the Illinois Home Repair and Remodeling Act?
The Home Repair and Remodeling Act (815 ILCS 513) regulates residential home-repair contracts. For projects over $1,000, contractors must provide a written contract that includes a description of work, total cost, and the consumer's right to cancel within 3 business days. The Act also requires the contractor to distribute the state's 'Home Repair: Know Your Consumer Rights' brochure. Critical for insurance: the Act creates a consumer claim right if the contractor fails to perform — but that right is only meaningful if the contractor has active GL and assets. Verify both.
What specific Illinois trade licenses should I verify?
Four. (1) Plumbing: Illinois Department of Public Health (IDPH) licenses all plumbers statewide — verify active license on the IDPH portal. (2) Roofing: Illinois Department of Financial and Professional Regulation (IDFPR) licenses roofers under the Illinois Roofing Industry Licensing Act. Licensure verifiable on IDFPR.illinois.gov. (3) Electrical: in Chicago, licensed by the Chicago Department of Buildings; suburbs vary (often via local building department). (4) HVAC: technician-level EPA Section 608 certification required federally, but Illinois has no state-level HVAC license — Chicago requires Journeyman HVAC Mechanic registration through DOB. Verify each trade license separately from the general DOB registration.
