How Mesa Handles Animal Ordinances: A Practical Guide

Mesa maintains 146 local ordinances across all categories, and 8 of those deal specifically with animal ordinances. Here is a breakdown of what the city actually requires, what is prohibited, and where Mesa falls on the strict-to-permissive spectrum compared to other cities.

Chickens & Livestock

Mesa bars livestock and similar large animals on any parcel smaller than 35,000 square feet under Mesa City Code § 8-6-21(B), and above that threshold caps the number of animals through an 'animal points' formula in § 8-6-21(C) that varies by parcel size and species.

Key details: Minimum lot size: 35,000 sq ft, § 8-6-21(B). Base points (35k–43,560 sq ft): 2 animal points, Table 8.6-A. Horse/cow value: 1 animal point per head, Table 8.6-C. Over-limit remedy: Special Use Permit under Title 11, § 8-6-21(C)(3). Swine rule: Banned except FFA/4-H or 2 pot-belly pigs, § 8-6-21(K).

Keeping livestock on an undersized lot or over the animal-points ceiling without a Special Use Permit is a civil violation of Chapter 6 under § 8-6-8, drawing a $250–$1,500 sanction for a first finding under § 8-6-9(A), rising to $350–$2,500 for a second and $500–$2,500 for a third within 36 months. Three findings in 36 months exposes the responsible party to habitual-offender prosecution under § 8-6-11: a class 1 misdemeanor with up to 6 months in jail and a fine of $500 to $2,500.

Compared to other cities, Mesa takes a harder line on chickens & livestock. The enforcement and penalty structure reflects that.

Dog Leash Laws

Mesa requires any dog off its owner's property to be restrained by a leash, chain, rope, or cord no more than six feet long, or otherwise confined to the property by a fence. Dogs found at large may be impounded, and owners face citations regardless of who was walking the dog.

Key details: Governing section: Mesa City Code § 6-4-7. Max leash length: 6 feet. Alternative: Confinement by adequate fence. Quarantine-area rule: No dog at large at all. Enforcement: Impoundment by enforcement agent.

Any dog found at large violates § 6-4-7, and the owner or custodian is responsible under Subsection (C) regardless of who was handling the dog. Citations are issued per the peace-officer notice procedure of A.R.S. § 13-3903, and loose dogs may be impounded by the enforcement agent.

Veterinary Clinic Zoning

Mesa allows veterinary clinics as a permitted, by-right "Veterinary Services" use in the NC, LC, GC, OC and MX commercial districts under Table 11-6-2 of the Zoning Ordinance: no special use permit needed. The only catch: every clinic must be confined to a completely enclosed, sound-attenuated building.

Key details: Permitted districts: NC, LC, GC, OC, MX (Table 11-6-2). Permit required: None: permitted by right, subject to Note 4. Building requirement: Fully enclosed, sound-attenuated facility. Excludes: Kennels: a separate, more restricted classification. First-offense penalty: $150-$1,500 civil sanction, § 11-79-4.

Operating a veterinary clinic outside an approved commercial district, or without the required fully enclosed, sound-attenuated building, is a civil zoning violation under Title 11, Chapter 79. The City Manager's designee issues a citation; a first finding of responsibility carries a civil sanction of $150-$1,500 under § 11-79-4(A), rising for repeat violations within 24-36 months, plus Code Compliance fees. Three violations in 24 months can trigger habitual-offender criminal prosecution under § 11-79-5.

Cat Rules

Mesa's animal-control chapter treats stray cats the same as stray dogs: any stray cat must be impounded and held a minimum of 72 hours, and an owner reclaiming a cat must prove ownership and pay all pound fees. Mesa has no separate cat-licensing requirement in this chapter.

Key details: Governing sections: Mesa City Code §§ 6-4-8, 6-4-9. Minimum hold: 72 hours before disposition. Reclaim requirement: Proof of ownership + all pound fees. Bite quarantine (unvaccinated): Minimum 10 days. Cat licensing: No individual cat-license fee in Ch. 4.

A stray cat is subject to impoundment under § 6-4-8 and held a minimum of 72 hours; an owner reclaiming it must furnish proof of right to the animal and pay all pound fees. An unvaccinated cat that bites a person must be quarantined at least 10 days under § 6-4-9.

Breed Restrictions

Mesa doesn't ban dog breeds, but its Police Chief can formally declare any individual dog "vicious" after a due-process hearing under Title 6, Chapter 4. Once declared, the owner must muzzle and confine the dog within one day, then secure a locked kennel, $100,000 liability insurance, and Police registration within 30 days.

Key details: Determination: Police Chief hearing, 10-day notice, due process. Immediate steps: Leash and muzzle, indoor confinement within 1 day. Compliance deadline: Kennel, registration, insurance within 30 days. Liability insurance: $100,000 per-incident minimum required. Penalty: $250-$2,500 fine and/or up to 6 months jail.

Failing to comply with any vicious-dog requirement is itself unlawful under Section 6-4-18. A conviction in Mesa Municipal Court carries a fine of not less than $250 and not more than $2,500, up to six months in jail, or both. The court can also order the dog impounded and destroyed, require the owner to pay all impound costs, and order restitution to any person or animal injured.

Compared to other cities, Mesa takes a harder line on breed restrictions. The enforcement and penalty structure reflects that.

Pet Limits

Mesa doesn't cap dogs by a bare household number, but keeping five or more dogs in a controlled enclosure meets the code's definition of a "kennel," which requires a county-issued kennel permit. Below that threshold, dogs are licensed individually rather than as a kennel operation.

Key details: Kennel threshold: 5 or more dogs (§ 6-4-1). Kennel permit fee: $75/year. Late-permit penalty: $25 added to annual fee. Permitting authority: County Board of Supervisors. Below threshold: Each dog individually licensed.

Operating a kennel (5+ dogs) without the required county-issued permit carries a $25 penalty on top of the $75 annual fee, and knowingly failing to obtain the permit within 30 days of written notice from the enforcement agent is a misdemeanor under § 6-4-4.

Beekeeping

Mesa confines beekeeping to two zoning districts: agricultural (AG) and single-family estate (R1-43) parcels. Mesa City Code § 8-6-21(M) states apiaries 'shall be limited to locations within agricultural and/or rural areas of the City, zoned AG or R1-43,' making beekeeping off-limits everywhere else in the city regardless of lot size.

Key details: Governing section: Mesa City Code § 8-6-21(M). Permitted zones: AG and R1-43 districts only. Chapter framework: Keeping permitted only per Ch. 6 conditions. First civil sanction: $250–$1,500 under § 8-6-9(A). Habitual offender risk: Class 1 misdemeanor after 3 findings, § 8-6-11.

Keeping an apiary outside an AG- or R1-43-zoned parcel is a civil violation of Mesa City Code Chapter 6, cited under § 8-6-8 and subject to the § 8-6-9(A) sanction schedule: $250–$1,500 for a first finding, $350–$2,500 for a second within 36 months, and $500–$2,500 for a third, plus Code Compliance fees. Three findings within 36 months triggers habitual-offender prosecution under § 8-6-11, a class 1 misdemeanor punishable by up to 6 months in jail and a $2,500 fine.

This is one of the stricter rules in Mesa's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Wildlife Feeding

Mesa treats deliberately feeding pigeons as a public nuisance. Section 8-6-3(AB) makes it unlawful to knowingly provide bird food to pigeons on private or public property, though feeders built to keep pigeons out are exempt, so backyard birdfeeding of other species stays legal.

Key details: Prohibited act: Knowingly feeding bird food to pigeons. Exception: Feeders designed to exclude pigeons. First-offense fine: $250–$1,500 civil sanction. Enforcing office: Code Compliance / Civil Hearing Officer.

A pigeon-feeding violation is processed as a civil nuisance citation under § 8-6-8: $250–$1,500 for a first finding under § 8-6-9(A), rising to $350–$2,500 for a second finding and $500–$2,500 for a third within 36 months, with repeat offenders risking habitual-offender misdemeanor prosecution under § 8-6-11.

Mesa is more permissive than most cities when it comes to wildlife feeding. That said, there are still limits.

The Bottom Line

Mesa is tougher than many cities when it comes to animal ordinances. Out of the 8 rules covered here, 3 are rated strict. If you are a homeowner, renter, or business owner in Mesa, 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 Mesa's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
