What to verify in Illinois

1. Business registration. Check the entity name, assumed names, and active status with the state office identified through USA.gov.
2. Contractor or trade authority. Ask the responsible state, county, or city whether the proposed repair, installation, structural, electrical, or commercial work requires a credential.
3. Project permits and inspections. Confirm requirements with the building department governing the jobsite, not only the business address.
4. Tax, employer, and insurance obligations. Verify the accounts and coverage appropriate to the company, employees, vehicles, and work.
5. Local operating rules. Check city and county business licenses, zoning, signage, disposal, and consumer requirements.
