Illinois Contractor Insurance Requirements
Illinois requires workers' compensation for employers with one or more employees under the Illinois Workers' Compensation Act (820 ILCS 305). The Illinois Department of Insurance and Department of Financial and Professional Regulation oversee contractor licensing. Chicago's construction market is one of the most active in the country, and the city has additional licensing and insurance requirements beyond the state minimums.
