Illinois general contractor license: state and local rules

IDFPR, the state agency that licenses professions, has no general contractor license on its list. The only contractor license there is for roofing. That means there's no state exam for an Illinois general contractor license. Before you bid, ask the building department where the job is what it requires. If the work includes roofing, the state roofing license applies.

Is there an Illinois general contractor license?

IDFPR doesn't list one. Its list of regulated professions includes architects, landscape architects, land surveyors, professional and structural engineers, home inspectors, and roofing contractors and their qualifying parties. Plumbing and electrical work aren't on it. The plumbing page covers who licenses plumbers in Illinois.

The Illinois roofing license and its exam

  • A limited license covers residential roofing, including buildings of 8 units or fewer. An unlimited license adds commercial and industrial roofing.
  • Every license names a qualifying party, a person who runs the roofing work day to day. That person passes the Illinois Residential exam or the Residential, Commercial and Industrial exam, the exam IDFPR sets.
  • The qualifying party has 3 years from the application to pass, or the fee is lost. A replacement qualifying party has 7 months.
  • The application fee is $125. You also file a surety bond and proof of at least $250,000 of property damage insurance and $500,000 of liability insurance per occurrence.
  • Every roofing license expires on December 31 of odd-numbered years.

IDFPR's consumer brochure tells homeowners hiring a roofing company or a general contractor for roofing to look for a license number starting with 104, and to check it on IDFPR's License Look Up.
