Hiring a General Contractor in Chicago, Illinois
In Illinois, general contractors must hold a license issued by the Illinois Department of Financial and Professional Regulation (IDFPR). Before hiring any contractor, you can verify their license status through IDFPR's online system at idfpr.illinois.gov. Call the department at 1 (888) 473-4858 if you have questions about a contractor's credentials or need assistance with the licensing lookup.
The City of Chicago Department of Buildings issues permits for construction work. Most projects require permits before work begins; the Department of Buildings website (chicago.gov) allows you to check permit status, search issued permits, and access forms. Ensure your contractor is familiar with Chicago's building and construction codes before signing an agreement.
When interviewing contractors, ask whether they hold a current state license and confirm you can verify it online. Inquire about their experience with permit applications and Chicago building codes, and ask whether they will handle permitting or you will be responsible for it. Understanding these details up front helps prevent delays and compliance issues.
