At the state level, contractors must obtain an Illinois General Contractor License through IDFPR for projects exceeding $50,000, which involves passing an exam and demonstrating relevant experience. Locally, Chicago requires contractor registration with the Department of Buildings and a separate business license, along with proof of substantial insurance coverage and bonding. The permitting process in Chicago is thorough and can be time-consuming, particularly for larger projects or work in historic areas. Contractors must be prepared for multiple inspections throughout the construction process and should factor permit timeline into project schedules. Success in Chicago's competitive market requires maintaining proper documentation, staying current with the city's evolving building codes, and building relationships with local inspectors and officials.

The license costs $300 initially and $150 for biennial renewal.
