Illinois does not issue a single statewide “general contractor” license for most handyman/home-repair work; instead, licensing is primarily trade-based (plumbing is state-licensed; electrical/HVAC are commonly licensed at the local level), and permits are issued by the local building authority. A true statewide “handyman exemption” with a single dollar threshold is not an Illinois-wide concept—what you can do legally depends on whether the work falls into state-regulated trades (especially plumbing) and whether the city/county requires contractor registration or a business license.
