Licensed General Contractor in Illinois: How to Verify Before You Hire

Illinois contractor licensing operates on a split system: the Illinois Department of Financial and Professional Regulation (IDFPR) at idfpr.illinois.gov licenses certain trades statewide, while the City of Chicago operates its own robust local licensing program for general contractors. If you are hiring a GC in Illinois, the applicable requirements depend significantly on where the project is located.

Does Illinois Have a Statewide General Contractor License?

Illinois does not have a single statewide general contractor license in the same way California or Florida does. The IDFPR regulates several trades including roofing contractors, but does not issue a general “building contractor” license at the state level. Instead, Illinois relies on a combination of state-level trade licensing, local municipal requirements, and the city-specific systems of major metro areas like Chicago to regulate general construction work.

For residential construction specifically, Illinois does not have a comprehensive statewide registration program equivalent to Pennsylvania's HICPA or New York's HIC system. This means Illinois homeowners outside Chicago must rely more heavily on verifying local permits, insurance, and trade-specific licenses rather than a single statewide GC credential.

The IDFPR does license roofing contractors statewide under a separate roofing contractor license. Roofers in Illinois must be IDFPR-licensed regardless of where in the state they work. This is one area where statewide licensing does apply, and it can be verified at idfpr.illinois.gov.

What Are Chicago's General Contractor Licensing Requirements?

The City of Chicago requires general contractors to hold a City of Chicago General Contractor licenseissued by the Department of Buildings. Chicago's licensing is separate from and in addition to any IDFPR requirements. Chicago GC licensees must pass an exam, demonstrate experience, carry insurance, and renew their license annually. The City of Chicago also requires specialty licenses for electrical, plumbing, and HVAC work performed within city limits.

Chicago's contractor licensing database is searchable through the City of Chicago's website. The Department of Buildings also maintains a permit search system where you can verify that a contractor has pulled the required permits for past projects. A GC who has never pulled a permit in Chicago but claims years of Chicago experience is a significant red flag.

What Insurance and Bond Should an Illinois GC Carry?

While Illinois does not mandate a specific statewide bond for general contractors, local municipalities often impose their own requirements. Chicago requires licensed GCs to carry general liability insurance and may require a bond depending on the license type. For any project over $10,000 in Illinois, standard practice is to require a minimum of $1,000,000 in general liability coverage per occurrence.

Illinois workers' compensation law requires employers with one or more employees to carry workers' comp insurance. The Illinois Workers' Compensation Commission reports that construction is among the highest-risk industries for workplace injuries. Confirming that your contractor carries workers' comp protects you from liability if a worker is injured on your property.

How Do You Verify a General Contractor's License in Illinois?

For IDFPR-licensed trades (including roofing), verify at idfpr.illinois.gov. For Chicago projects, verify at the City of Chicago Department of Buildings website. For municipalities outside Chicago — suburbs like Naperville, Evanston, or Rockford — contact the local building department directly to confirm what licensing requirements apply.

Ask any Illinois GC for the specific license numbers that apply to your project's location and scope. Confirm the license is active, the expiration date is current, and insurance is on file. Also ask what permits they plan to pull and verify with the local building department that those permits were issued.
