Illinois Contractor & Trade License Requirements
Illinois does NOT have a statewide general contractor license — licensing is handled at the city/county level (e.g., Chicago Department of Buildings). However, Illinois is unique in requiring statewide roofing contractor licensing under the Roofing Industry Licensing Act (administered by IDFPR). Plumbers are licensed statewide through the Illinois Department of Public Health (IDPH). Electricians and HVAC technicians have no statewide license; both are regulated locally. Federal EPA 608 certification is required for HVAC refrigerant work.
