In Illinois, general contractors are regulated by the Illinois Department of Financial and Professional Regulation (IDFPR). Before hiring a contractor, verify their license status through IDFPR's online licensing portal at idfpr.illinois.gov, where you can check if an individual or entity holds an active license. You can also call IDFPR at 1-888-473-4858 with questions about licensing requirements.

In Chicago, most construction work requires a permit from the Department of Buildings. The city issues permits to ensure construction meets code and safety standards. Before your contractor begins work, confirm that all necessary permits have been obtained and will be pulled at the start of the project—this protects both you and the work being done.

When interviewing a general contractor, ask whether they hold the appropriate Illinois license for the scope of work you need, what their typical process is for defining scope and managing timelines, and how they coordinate permits and inspections with the city. Understanding their approach upfront helps ensure clarity and accountability throughout your project.
