Arlington Heights FAQ
How many pets can I have in unincorporated Cook County?
Cook County Code Chapter 30 generally permits up to about four dogs or cats over six months per residence without a CCDARC kennel permit. Higher counts require permitting, neighbor notice, and zoning compatibility review.
Do these limits apply in Cook suburbs?
Not directly. Most Cook suburbs adopt their own household limits, often three dogs. Check the local municipal code first; the county Chapter 30 baseline only governs unincorporated areas and county-run programs.
Chicago FAQ
Does the limit count puppies?
Only dogs older than four months count toward the five-dog cap under MCC 7-12-050. A litter under that age is excluded, but you must rehome or license once any pup ages past the threshold.
Can I keep ten cats legally?
Yes, the five-pet cap covers dogs only. Cats face no numeric limit, but hoarding situations covered by MCC 7-12-080 and Illinois 510 ILCS 70 can still trigger CACC seizure and prosecution.
