Elmhurst FAQ
Are pit bulls legal in DuPage County, IL?
Yes. The Illinois Animal Control Act, 510 ILCS 5/15, prohibits classifying vicious dogs by breed, and DuPage County Code Ch. 5 has no breed-specific ban. Pit bulls, Rottweilers, and similar breeds are legal in unincorporated DuPage County.
Can my municipality in DuPage County pass its own pit bull ban?
No. 510 ILCS 5/15 establishes statewide that vicious-dog regulations may not be breed-specific. A municipal breed ban would conflict with state law and is not enforceable as a vicious/dangerous-dog classification.
How does DuPage County handle truly dangerous dogs without using breed?
The DuPage County Animal Services Administrator can declare an individual dog "dangerous" or "vicious" under 510 ILCS 5/2.05a and 5/15 based on the dog's specific behavior — attacks, threats, and bite history. A vicious finding requires a $100 fine, spay/neuter, microchip, and approved enclosure, and is appealable to the Circuit Court within 14 days.
My landlord or insurance company says no pit bulls — is that legal?
Yes. 510 ILCS 5/15 restricts only governmental breed classification. Landlords, HOAs, and homeowner-insurance carriers can still impose private breed restrictions in their leases or policies, and those private contracts remain enforceable in DuPage County.
