Summary

Every animal Aurora, Illinois's Animal Care & Control Division impounds must be microchipped before it's released back to its owner: a citywide condition tied to redemption, on top of the redemption fine itself.

For every animal taken up and impounded as provided in this chapter, there will be a fine assessed to the owner by the Aurora Division of Animal Care & Control in an amount set by resolution as approved by the City Council and made public. The owner or owner's designated agent may redeem the animal and the owner will be required to provide proof of ownership sufficient to the requirements of the director prior to the animal being released. Any animal impounded shall be microchipped before its release to its owner.

Additionally, any animal for which there are three (3) documented cases of the animal running at large shall be spayed or neutered prior to its release to its owners after payment of the fee is made. After payment of the veterinarian fee for spay or neuter, as well as completion of all necessary documentation and paperwork required by the city, the animal shall be transported by an animal control officer to the veterinarian of the owner's choice within the city or a veterinarian approved by the director for immediate spay or neuter. If the animal cannot be spayed or neutered, as determined by a veterinarian, in writing, due to age or a medical condition, the animal shall be spayed or neutered upon the removal of the veterinarian's restriction or the achievement of a designated date.

(Ord. No. O94-18, § 1, 3-1-94; Ord. No. O00-32, § 1, 3-28-00; Ord. No. O02-99, § 12, 9-10-02; Ord. No. O06-12, § 4, 2-28-06; Ord. No. O07-98, § 1, 8-28-07)

Full Breakdown

Aurora Code of Ordinances § 9-25 (Redemption) requires that any animal taken up and impounded under Chapter 9 be microchipped before release back to its owner, in addition to a Council-set redemption fine. Two related sections layer microchipping requirements on top: § 9-13 requires an animal involved in a bite or attack to be microchipped at the owner's cost if it lacks one, and potentially dangerous dogs must be spayed/neutered and microchipped within 14 days of reclaim. Aurora's microchip rule is a release condition tied to impoundment, bites and dangerous-dog reclaim, not a blanket chip mandate for every owned pet.

Violations & Fines

An owner cannot redeem an impounded animal without the required microchip and the Council-set redemption fine; noncompliance keeps the animal in the division's custody pending placement.

Frequently Asked Questions

Does Aurora require microchipping for all pet owners?

Who pays for the microchip?
The owner, at their own cost, under §§ 9-13 and 9-25 of the city code.
