Illinois has no statewide GC license. Plumbers (IDFPR), roofers (IDFPR Roofing Contractor License), and most electricians (city/county) are licensed by trade. Chicago has its own GC and trade-licensing structure under DOB.
Illinois Workers' Compensation Act applies to all employers from first hire. Sole proprietors, partners, and corporate officers may elect to be excluded but must file the exclusion. No employee-count threshold.
These are limits commonly required on IL public-works prequalification. They are NOT a state-mandated minimum — verify against your specific procurement spec or contract.
