Business licenses and permits in Cook County, Illinois
Cook County's licensing footprint depends entirely on where inside the county a business sits. The City of Chicago runs its own business-licensing department (BACP) and its own health department, and is outside almost every county requirement listed for Cook County. Roughly 130 other incorporated suburban municipalities can run their own local business licensing, but still sit inside the county's health and environmental jurisdiction: the Cook County Department of Public Health (CCDPH) and Department of Environment and Sustainability (DES) reach every municipality in the county except Chicago. Unincorporated Cook County is the only place the county itself is the sole local regulator, and it is where the county's General Business License, Liquor License, building/zoning permits, Contractor Registration, Sign Permit, Alarm Permit, Home Occupation review and Retail Tobacco License all apply — each of those is absent inside Chicago and inside every other incorporated suburb, which run their own versions instead. Only the Cook County Clerk's Assumed Business Name registration, under the state Assumed Business Name Act, reaches the whole county including Chicago. Cook County's animal-control function (Animal and Rabies Control, or ARC) applies directly in unincorporated Cook County, and many but not necessarily all suburban municipalities have separately adopted the county's ordinance by reference. Several county functions that might be assumed to exist do not: the county wheel tax was repealed effective June 30, 2023; kennel, pet-shop and animal-breeder licensing is an Illinois Department of Agriculture function, not a county one; and weights-and-measures device inspection is likewise a state (or, inside Chicago, a city) function with no distinct Cook County program.
What are you opening in Cook County?
- RestaurantsFull-service restaurants carry the densest permit load of any small business: food, fire, occupancy, waste, and usually alcohol.See the full permit list
- Coffee shopsCafés are permitted as food service establishments even where no cooking happens, and the plan review step catches most operators by surprise.See the full permit list
- Retail storesRetail is the lightest common permit load, but the sales tax permit and the certificate of occupancy are non-negotiable in every jurisdiction.See the full permit list
- Salons and barbersPersonal care is licensed at state board level as well as locally, so the shop license and the practitioner licenses are separate obligations.See the full permit list
- Food trucksMobile food is the one category with no certificate of occupancy — but it gains a commissary agreement, and the unit itself is inspected rather than the premises.See the full permit list
- Fitness studiosPrepaid memberships trigger state registration and often a surety bond, which catches operators who budgeted only for the fit-out.See the full permit list
- Childcare centresThe heaviest permit load of any small business: state agency licensing, per-person background checks, and a stricter fire standard than ordinary commercial use.See the full permit list
- Contractors and tradesLicensed at state board level rather than locally, and the only common category with no premises permits at all — the bond is usually the long pole.See the full permit list
- Auto repair shopsOrdinary commercial permitting plus an environmental layer: waste oil, solvents and stormwater are each registered separately.See the full permit list
- Veterinary clinicsA state facility permit, controlled substances registration at both state and federal level, and a medical waste manifest — none of which a general business license covers.See the full permit list

What do these permits involve in Cook County?
Assumed Business Name Registration ("DBA")
This is the only county-level requirement listed for Cook County that reaches a business inside the City of Chicago as well as suburban and unincorporated Cook County, because the Cook County Clerk is the county-wide filer under the Illinois Assumed Business Name Act. It applies to a sole proprietorship, general partnership or professional-service corporation trading under a name other than the owner's own legal name; it does not apply to an LLC, corporation, LP or LLP, each of which files its assumed name with the Illinois Secretary of State instead, and it does not apply to a sole proprietor trading under their own full legal name. The fee is a flat $50, filed online through the Clerk's assumed-names portal. No county source describes a periodic renewal requirement after the initial three-week publication and 50-day proof-of-publication cycle.
Business Occupancy / Building Permit and Certificate of Occupancy (unincorporated Cook County)
A physical business location in unincorporated Cook County (and the Forest Preserves of Cook County) needs a Business Occupancy approval from Building and Zoning before opening, again for any construction, remodeling or change in operations, and is otherwise re-inspected annually. Inside Chicago or any other incorporated suburb, that municipality's own building and occupancy process applies instead. The application deposit is $100 for a residential business-occupancy application and $500 for non-residential, credited against the final permit fee when it is issued; Cook County's complete valuation-based or flat final fee schedule beyond that deposit is not available in any retrievable current document and is not published here — confirm the total cost with Building and Zoning before budgeting for it. A business adding a Liquor License or video gaming terminals must separately update its zoning/occupancy approval and obtain a building permit verifying the terminal installation or alcohol-service space.
County Wheel Tax / Vehicle License — Repealed June 30, 2023 (Cook County)
No fee applies. Cook County formerly required an annual wheel-tax sticker for every vehicle kept in unincorporated Cook County, including a business's own fleet or service vehicles, but, according to the County's own announcements, the County Board voted unanimously on September 22, 2022 to pass the Wheel Tax Elimination Ordinance, and the repeal took effect June 30, 2023, so no county wheel tax has been due since July 1, 2023. This entry exists so an auto-repair shop, contractor or any other business with vehicles based in unincorporated Cook County does not budget for a fee the county no longer charges. It has no bearing on the separate Illinois vehicle registration or on any wheel tax a specific municipality may still run within its own borders.
Asbestos Abatement Permit
Any renovation or demolition project in suburban or unincorporated Cook County that disturbs asbestos-containing material needs this permit, filed at least 10 business days before work starts — Chicago runs its own separate asbestos program instead. A residential project pays a flat $200 filing fee; a commercial project pays $200 plus $6 per square foot or $2 per linear foot of the abated area, capped at $2,000, all non-refundable. Municipal demolition of a residential structure has been exempt from this fee since March 1, 2024. This applies to any of the nine physical-premises industries covered here renovating or demolishing an older building, in addition to the abatement contractor itself, who separately needs the Contractor Registration above.
Demolition Permit
Demolishing an existing structure in suburban or unincorporated Cook County requires a DES demolition permit — Chicago runs its own separate demolition program. A residential demolition is $300 for the first structure and $150 for each additional structure on the same site; a commercial demolition, or a residential demolition of 5 or more units, is $750 per structure; removing a permit hold is $55. A property in unincorporated Cook County also needs a separate Building and Zoning building permit on top of this DES permit. The application requires an asbestos-inspection report, property-tax documentation, a plat survey or photos, and a Demolition Debris Diversion Plan targeting 70% debris diversion and 5% material reuse for a residential project.
