How Dearborn Handles Animal Ordinances: A Practical Guide

Dearborn maintains 139 local ordinances across all categories, and 9 of those deal specifically with animal ordinances. Here is a breakdown of what the city actually requires, what is prohibited, and where Dearborn falls on the strict-to-permissive spectrum compared to other cities.

Dog Leash Laws

Dearborn bars dogs from every city park except the Dearborn Dog Park, and requires any dog on a public street or highway to be held on a leash of suitable strength by its owner and currently vaccinated against rabies. Code of Ordinances § 4-22 also makes owners strictly liable for bite injuries under state law, backed by a fine schedule that starts at $75.00 and rises to a 93-day misdemeanor.

Key details: Leash required on: All public highways and streets. Park rule: Dogs barred except Dearborn Dog Park. Vaccination required: Current rabies immunization. Owner liability: Strict liability, MCL § 287.321. Governing section: Code of Ordinances § 4-22.

Section 4-6's fine schedule governs Chapter 4 violations, including § 4-22: a $75.00 civil infraction for a first offense, $100.00 for a second, $250.00 for a third, and a 93-day misdemeanor as defined in § 1-9 for a fourth and subsequent offense. An owner is additionally exposed to civil liability for any injury the dog inflicts, without regard to the dog's prior behavior, under MCL § 287.321 and § 287.351.

Veterinary Clinic Zoning

Dearborn's Zoning Ordinance gives veterinary clinics and veterinary hospitals separate site standards under Article 7.00. Clinics need only a 50-foot setback from residentially zoned land; hospitals need 200 feet. Both must operate inside a fully enclosed building, cannot run an exterior animal-boarding facility, and may treat only domesticated pets.

Key details: Clinic setback: 50 ft from residential land. Hospital setback: 200 ft from residential land. Building requirement: Fully enclosed, no exterior boarding. Treatment scope: Domesticated pets only. O-S district status: Special land use, § 13.02.B.3.

Zoning violations fall under Sec. 32.09 of the Dearborn Zoning Ordinance. A building or use maintained in violation is declared a public nuisance per se, subject to court-ordered abatement. Conviction is a misdemeanor punishable by a fine up to $500.00 or up to 90 days in jail, or both, and each day the violation continues is a separate offense. The city attorney may also seek injunctive relief.

Mandatory Spay/Neuter

Dearborn requires owners of dogs formally declared "dangerous" to have them spayed or neutered and microchipped within 14 days, at the owner's own expense, under Code of Ordinances § 4-27A(c).

Key details: Trigger: Dog declared dangerous. Deadline: 14 days from determination. Who pays: Owner, at own expense. Also required: Microchip + behaviorist evaluation.

Noncompliance can lead to impoundment of the dog under § 4-27A(d). A dog later found vicious after evaluation faces licensing, $100,000 insurance, and confinement requirements under § 4-27B.

Pet Limits

Dearborn treats keeping more animals than a property can reasonably support as a nuisance in itself, judged case by case against factors like waste buildup, odor, structural damage, and animals running at large.

Key details: Standard: Case-by-case, no fixed cap. Governing section: § 13-2(20). First-offense fine: $250 civil infraction. Repeat-offense fine: $500 within 6 months. Enforced by: Police, Building & Safety, DPW.

Maintaining an excessive-animal nuisance violates § 13-3: a $250 civil fine for a first offense, $500 for a repeat violation within six months, with each day a separate offense.

This is not one of those rules that cities tend to ignore. Dearborn actively enforces its pet limits requirements.

Exotic Pets

Dearborn outlaws keeping exotic, wild, or dangerous animals within city limits, naming hedgehogs, skunks, raccoons, alligators, tigers, lions, monkeys, and constrictor snakes as prohibited pets.

Key details: Banned animals: raccoons, alligators, tigers, monkeys, snakes. Permit option: none: outright prohibited. Enforcement: police-run animal shelter. First offense fine: $75 civil infraction.

Violations fall under the Chapter 4 fine schedule in Sec. 4-6: $75 for a first civil infraction, $100 for a second, $250 for a third, and a 93-day misdemeanor for a fourth or later offense; the animal itself is subject to impoundment.

Compared to other cities, Dearborn takes a harder line on exotic pets. The enforcement and penalty structure reflects that.

Wildlife Feeding

Dearborn declares feeding pigeons or ground-feeding any bird a nuisance per se, no case-by-case finding required: a stricter standard than the excessive-animals rule that applies to household pets.

Key details: Rule: Ground-feeding any bird banned. Standard: Nuisance per se, no proof needed. Governing section: § 13-2(19). First-offense fine: $250 civil infraction.

Ground-feeding any bird or feeding pigeons to encourage roosting violates § 13-2(19) as a nuisance per se; enforcement follows § 13-3's civil fines, $250 first offense, $500 for a repeat within six months.

This is not one of those rules that cities tend to ignore. Dearborn actively enforces its wildlife feeding requirements.

Microchipping

Dearborn does not require every dog to be microchipped, but its dog-licensing scheme in City Code Sec. 4-23 builds microchipping directly into the fee structure and offers a free automatic-renewal license only to dogs that are both sterilized and microchipped.

Key details: Governing section: Code of Ordinances § 4-23(b). Microchip requirement: Not mandatory citywide. Incentive: Reduced fee if sterilized/microchipped. Auto-renewal license: Requires sterilization + microchip. License administrator: Dearborn city clerk.

Failing to license a dog six months or older is a civil infraction: $75 for a first offense, $100 for a second, rising to a 93-day misdemeanor with up to a $500 fine for a third or subsequent violation under the Sec. 4-6 fine schedule. There is no separate penalty for skipping microchipping itself since it is incentivized through fees, not mandated; a dangerous dog owner who fails to complete the court-ordered microchipping and sterilization under Sec. 4-27A(c) risks impoundment of the dog.

Chickens & Livestock

Dearborn requires a permit from the director of residential services before keeping chickens, pigeons, or other fowl, or farm animals like cows, horses, pigs, goats, and sheep, anywhere in the city.

Key details: Permit issued by: director of residential services. Covered animals: cows, horses, pigs, goats, sheep, fowl. Exempt pets: dogs, cats, birds. Permit can be: suspended for nuisance.

Keeping fowl or farm animals without a permit, or letting a permitted animal create a nuisance, is a chapter violation under the Sec. 4-6 fine schedule: $75 first offense, $100 second, $250 third, then a 93-day misdemeanor.

This is not one of those rules that cities tend to ignore. Dearborn actively enforces its chickens & livestock requirements.

Breed Restrictions

Dearborn does not ban or restrict dogs by breed. City Code § 4-27 defines "dangerous" and "vicious" dogs by their behavior, bites, attacks, threats, not by breed, size, or type.

Key details: Governing standard: Behavior, not breed. Dangerous-dog finding: Made by Animal Shelter manager. Vicious-dog finding: Made by 19th District Court. Citation: Code of Ordinances § 4-27.

Dangerous-dog owners must spay/neuter and microchip the dog within 14 days, complete a behaviorist evaluation, and may face impoundment. Vicious-dog owners face licensing, $100,000 liability insurance, confinement, and misdemeanor penalties for noncompliance.

The Bottom Line

Dearborn is tougher than many cities when it comes to animal ordinances. Out of the 9 rules covered here, 4 are rated strict. If you are a homeowner, renter, or business owner in Dearborn, take the time to understand these requirements before they become a problem. Most violations come with fines, and some repeat violations can escalate.

These rules come from Dearborn's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
