There is no Illinois general contractor or home improvement license. What the state imposes is the Home Repair and Remodeling Act (815 ILCS 513): liability insurance of $100,000/$300,000 bodily injury and $50,000 property damage, a written contract for jobs over $1,000, and the 'Home Repair: Know Your Consumer Rights' pamphlet with a signed acknowledgment. Violations are Consumer Fraud Act violations.
Chicago is the heavyweight. A city general contractor license is required for most building construction, alteration, repair, and demolition, sorted by maximum project value: Class A unlimited, B $20 million, C $10 million, D $4 million, E $500,000. On January 6, 2026 the city raised Class A–D fees for the first time since 2003, doubled the B/C/D project caps, and raised Class C/D insurance to $2 million per occurrence.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Illinois leaves contractor licensing to local government. Chicago requires its own general contractor license for permitted construction, demolition, and rehabilitation; only one GC may be on a project at a time, and subcontractors working outside the GC's supervision need their own license and permit listing. Suburban municipalities run their own registration and permit regimes.

First fee increase since 2003 for Classes A–D; B/C/D project limits doubled; fees adjust by CPI each year from 2027.
Chicago counts the fair market value of all labor and materials by all contractors across concurrent and consecutive work at the same site.
The Home Repair Act covers residential repair and remodeling on buildings of 6 or fewer units — not original construction of new homes.
