Cook County Code Chapter 30 caps household pet counts in unincorporated Cook, generally allowing up to four dogs or cats over six months without a kennel permit. Suburban Cook municipalities frequently set lower limits independently of the county rule.
Under Cook County Code Chapter 30 (animal control), unincorporated single-family residences may keep a limited number of dogs and cats over six months old, generally capped around four total without a CCDARC kennel permit. Higher counts trigger a kennel or hobby-breeder permit, neighbor notice, and inspection. Many Cook suburbs (Evanston, Oak Park, Schaumburg, Cicero) set their own household limits, often three dogs per residence, controlling within their borders. The Illinois Animal Control Act (510 ILCS 5) leaves numeric limits to local governments. Kennel zoning compatibility is reviewed under Cook County Zoning (Chapter 102).
Exceeding pet limits in unincorporated Cook draws administrative citations and CCDARC kennel-permit demands. Persistent overcounts can trigger zoning enforcement under Chapter 102, and in welfare cases the seizures available under 510 ILCS 70 (Humane Care for Animals Act).
