Illinois businesses operate under a complex web of state, county, and municipal licensing and regulatory requirements. Due diligence for licensing means confirming that all required licenses are current, valid, and either transferable to the buyer or obtainable without unreasonable delay or cost.
Common Illinois Licensing Requirements
Depending on business type, review may include: Illinois Department of Public Health licenses (food service, childcare, home health, assisted living), Illinois Department of Professional Regulation licenses (medical, dental, pharmacy, cosmetology, engineering, accounting), Illinois Liquor Control Commission license (bars, restaurants, c-stores), Illinois Environmental Protection Agency permits (generators of waste, UST operators), local business operating licenses (city or county-specific), and specialized federal permits (FCC, FTC, FMCSA for transportation).
Transfer vs. Re-Application
Some licenses transfer automatically with business ownership; others require the new owner to apply for a new license before the closing or before they can legally operate. Understanding which licenses require new applications — and the timeline and requirements for those applications — is essential planning information. Licenses that require 60–90 days processing time should be applied for immediately after LOI signing.
Compliance history review — whether the business has any prior regulatory violations, consent orders, or pending investigations — is as important as license currency. A business with a pattern of IDPH violations or IDOR audit issues presents risks that a clean license review alone would not reveal. Check agency databases and request seller disclosure of any regulatory correspondence in the past three years.
