In Maricopa County, you can keep up to four dogs at a residential property without any special paperwork beyond licensing each one. The moment you add a fifth, Arizona law and Maricopa County Ordinance P-13 classify your home as a kennel, and you must either obtain a kennel permit from the Board of Supervisors or license every dog in the household individually.1Maricopa County. Maricopa County Ordinance P-13 – Rabies/Animal Control There is no outright cap on ownership, but the kennel threshold is the line that changes what the county requires of you.
Why Five Dogs Changes Everything
Arizona defines a kennel as an enclosed, controlled area where someone keeps five or more dogs under controlled conditions. That definition is what creates the effective four-dog household limit. The county won’t fine you for owning a fifth dog in itself, but kennel rules switch on at that number, and ignoring them is its own violation.
Getting a Kennel Permit for Five or More
If you want to keep five or more dogs and prefer not to license each one separately, you need a kennel permit from the Maricopa County Board of Supervisors.2Arizona Legislature. Arizona Code 11-1009 – Kennel Permit; Fee; Denial; Inspection; Violation; Classification You submit a written application with a fee. State law sets a baseline annual fee of $75 or the actual cost of recovery, and Maricopa County’s current application charges $350.3Maricopa County. Kennel Permit Application An Animal Control Officer then schedules an inspection of the property.
A few points worth knowing before you apply:
- Dogs kept inside the kennel do not need individual licenses. Any dog that leaves the kennel must be licensed separately, unless it is being transported to another permitted kennel.
- The county can deny a permit to anyone convicted of animal cruelty or a similar welfare offense under Arizona law. Prior leash or licensing violations alone are not a disqualifier.
- Kennels with fewer than twenty dogs are inspected only when the county receives a written complaint alleging cruelty.
City and HOA Limits Can Be Stricter
The four-dog figure governs unincorporated Maricopa County. Inside incorporated cities, the municipal code typically governs, and some cities set lower limits than the county. Check your city’s ordinance before you count on the county rule.
Homeowners’ associations add another layer. Most HOAs in the Phoenix metro area include pet provisions in their CC&Rs, and those commonly limit number, size, or breed. An HOA can enforce a two-dog cap even where the county would allow four. If you’re buying into a planned community, read the CC&Rs before you assume the county rule is the only one that applies.
Every Dog Still Needs a License
Separate from the kennel question, every dog over three months of age that lives in Maricopa County for at least thirty consecutive days in a calendar year must be licensed and vaccinated against rabies.4Maricopa County. Maricopa County – Dog License A one-dog home needs a current license just as much as a four-dog home does.
To apply, you need a completed rabies vaccination certificate showing the owner’s name and address, the dog’s information, the vaccination date, the vaccine manufacturer and serial number, and the veterinarian’s details. Applications go through DocuPet online, by mail, or in person at the Maricopa County Animal Care and Control shelter.
Annual license fees:
- Spayed or neutered dog: $22
- Unaltered dog: $55
- Senior discount (owner 65 or older): $10 per altered dog
Licenses renew annually based on the date of your dog’s most recent rabies vaccination, even if the vaccination itself is still current. Late fees run $3 per month for altered dogs and $6 per month for unaltered dogs. State law adds a separate penalty of $2 if you apply less than a year late, with another $10 for each subsequent year up to a $22 maximum.5Arizona Legislature. Arizona Code 11-1008 – License Fees for Dogs; Issuance of Dog Tags; Exception With multiple dogs, those numbers add up fast.
The Service Animal Exception
Cities and towns in Arizona cannot charge a license fee for a service animal or a search and rescue dog.6Arizona Legislature. Arizona Code 9-500.32 – License Fees for Dogs; Prohibition; Violation; Classification Arizona defines a service animal as a dog or miniature horse individually trained to perform tasks for a person with a disability.7Arizona Legislature. Arizona Code 11-1024 – Service Animals; Rights of Individuals With Disabilities Emotional support animals do not qualify under this definition, and neither does a dog whose only role is comfort or companionship. To claim the exemption, you sign a Declaration of Service Animal Form through Maricopa County Animal Care and Control; a false statement on that form is a petty offense carrying a fine of up to $50.
Renters should know that federal fair housing rules may require landlords to grant reasonable accommodations for assistance animals, including emotional support animals, even where a lease or HOA restricts pets. Federal guidance recognizes a household may need more than one assistance animal where each serves a disability-related purpose. That protection applies to housing only. It does not override county licensing or the kennel permit requirement.
What It Costs to Get This Wrong
Any violation of Ordinance P-13 is a Class 2 misdemeanor, punishable by up to four months in jail, a fine of up to $750, or both. That umbrella covers running an unlicensed kennel and letting a dog run at large.
Specific penalties worth noting:
- Operating a kennel without a permit: a $25 penalty on top of the annual fee. Knowingly refusing to get the permit within thirty days of written notice from an enforcement agent escalates the charge to a Class 2 misdemeanor.
- Failing to license a dog: late penalties start at $2 and reach $22 over time, and knowingly ignoring a written notice to license within fifteen days is a Class 2 misdemeanor.
- A dog at large that causes injury or property damage: the owner, or whoever was responsible for the dog at the time, is fully liable.
In unincorporated Maricopa County, every dog must be inside an enclosure on the owner’s property, otherwise secured so it cannot leave, or held on a leash no longer than six feet under the owner’s direct control. The only exceptions are dogs used for livestock control and dogs being used or trained for hunting.8Arizona Legislature. Arizona Code 11-1005 – Powers and Duties of Board of Supervisors A dog found off the owner’s property without a leash is considered at large and can be impounded.
Then there is bite liability. Arizona is a strict liability state for dog bites: if your dog bites someone who is in a public place or lawfully on private property, you’re liable for damages regardless of any prior history.9Arizona Legislature. Arizona Code 11-1025 – Liability for Dog Bites; Owner Information; Military and Police Work There is no first-bite defense. Every additional dog raises that exposure, which is why homeowner’s or renter’s insurance with adequate pet liability coverage matters more as your pack grows.
