Illinois is a "Home Rule" state, which implies there is no single state-wide license for General Contractors. However, if you want to work where the money is—Chicago—you must navigate one of the most complex licensing systems in the Midwest. The Department of Buildings (DOB) strictly regulates who can build in the Windy City.

- Class A (General Contractor): Unlimited. You can build skyscrapers, hospitals, and stadiums. Requires a $5 Million insurance policy.

2. Step-by-Step: How to Get Licensed in Chicago
Step 1: Pass the ICC Exam
Before applying, the "qualifying party" of your company must pass the relevant exam administered by Continental Testing Services.
• For Class E, take the "Class E Residential Building Contractor" exam.
• It is an open-book test based on the Chicago Building Code.
Step 2: Business Registration
You must register your business with the Illinois Secretary of State and the City of Chicago. You will need a Federal EIN and a clean background check.
Step 3: Secure Insurance
You cannot submit your application without a Certificate of Insurance. The policy must name the "City of Chicago" as the certificate holder.
