Arizona Pet Sitting, Dog Walking & Grooming Side Hustles: Licenses, Kennel Permits, and Taxes

TL;DR

• No state license for pet sitting, dog walking, or grooming. We found no Arizona statute, board, or exam that licenses these jobs. The Arizona Commerce Authority's small business checklist sends groomers to their county health or environmental services department for any local permits. (Arizona Commerce Authority.)
• Five or more dogs at your place can make it a "kennel." State law defines a kennel as an enclosed, controlled area where a person keeps five or more dogs, and requires a county kennel permit unless each dog is individually licensed. (A.R.S. §§ 11-1001, 11-1009.) Maricopa County's application lists a $350 fee; Pima County Code sets $400 or 75% of the cost of licensing each dog individually, whichever is greater. Confirm whether boarding clients' already-licensed dogs triggers a permit with your county.
• Phoenix doesn't allow dog grooming as a home occupation. The Phoenix Zoning Ordinance lists "dog grooming" and "commercial kennels" among uses a home occupation may not include. (Phoenix Zoning Ordinance § 608.) Mobile grooming and going to the client's home are different questions; confirm with Phoenix Planning & Development.
• Services generally aren't taxed by TPT; products are. Arizona's retail TPT excludes personal service businesses where goods are only an "inconsequential" part of the job, but selling shampoo, treats, or collars is retail. (A.R.S. § 42-5061; ADOR.)
• Federal taxes still apply. Net self-employment earnings of $400 or more generally trigger self-employment tax, even if no 1099 arrives. (IRS.)

Who this guide is for

You want to earn extra money caring for animals in Arizona: drop-in visits, overnight house-sitting, dog walking, in-home boarding, or grooming (mobile, at clients' homes, or at your house). This page covers the paperwork: licenses, kennel permits, zoning, and taxes. Our Best Side Hustles in Phoenix guide covers local demand and seasonality.

We don't publish income claims, and we don't rank pet apps.

Which rules apply to which kind of pet work

Step 1: Confirm there's no license for your exact service

Arizona doesn't license pet sitters, dog walkers, or groomers at the state level. That's our reading of the statutes and agency pages listed below; we found no state board or exam for these jobs. The Arizona Commerce Authority's checklist entry for pet grooming says groomers, "whether portable, permanent and/or mobile," should contact their local county health/environmental services department for any permitting requirements, and check local business license rules. (Arizona Commerce Authority.)

Some counties do regulate grooming facilities. Mohave County's Environmental Health Division, for example, inspects and permits pet shops, kennels, and grooming parlors, requires plan review before opening, and has a commissary agreement form for mobile grooming. (Mohave County.) Check your own county before you buy equipment.

Veterinary work is different. Diagnosing or treating animals for pay is veterinary practice, which Arizona regulates separately. Stick to care, exercise, and grooming, and send medical questions to the owner's veterinarian.

Step 2: Boarding at home? Count the dogs

Under A.R.S. § 11-1001(8), a kennel is "an enclosed, controlled area, inaccessible to other animals, in which a person keeps, harbors or maintains five or more dogs under controlled conditions." A.R.S. § 11-1009 says a person operating a kennel must get a permit from the county board of supervisors except if each individual dog is licensed. The state law sets the annual fee at $75 "or the actual cost of recovery as determined by the board of supervisors," so county fees vary.

(Maricopa County Kennel Permit Application; Pima County Code § 6.04.070(K). Confirm current fees with each county before applying.)

What this means for a pet-sitting side hustle: The kennel rule is about licensing the dogs kept at a location. Client dogs that already carry a current license may not count the same way as unlicensed dogs, and Maricopa's application says the permit "does not authorize the operation of any type of business." We didn't find an official statement on exactly how boarding licensed client dogs is treated. Confirm with your county animal care agency before you take five or more dogs at once, and remember your own dogs count toward what's on the property.

Zoning for in-home boarding

• Phoenix: The zoning ordinance says a home occupation "shall not include" uses such as dog grooming, veterinary hospitals and commercial kennels, and commercial stables. (Phoenix Zoning Ordinance § 608.)
• Unincorporated Maricopa County: A county drawing-and-design directive (DD-2020-02) says small-animal boarding, breeding, rescue, and training can run as a home-based business without extra zoning entitlement if animals are housed inside a fully enclosed, ventilated building; outdoor exercise is limited to 25% of the parcel and fully screened; no more than three non-resident employees or volunteers; and no more than five customers on site at a time. Otherwise a special use permit or other zoning is needed. (Maricopa County.)
• Other cities: Each city writes its own home occupation code. See our Arizona home occupation permits guide and the city-by-city guides for the East Valley, West Valley, and Tucson, Oro Valley, Marana, and Sahuarita.

HOA rules can be stricter than zoning. Read your CC&Rs before you board dogs.

Step 3: Grooming from home vs. mobile vs. at the client's house

• At your house in Phoenix: Not allowed as a home occupation under § 608, as quoted above. Renting a chair or space in a commercial grooming shop is the usual alternative; confirm zoning with the city for any space you lease.
• Mobile grooming: You're working from a vehicle, so the questions are where the van parks overnight, where you get water, and where wastewater goes. Some counties (Mohave, for example) have mobile grooming paperwork. Ask your city and county before your first appointment.
• In the client's home: Usually the simplest setup, because no customers or animals come to your property. You may still need a city business license where the city requires one (see below).

Step 4: City business license and TPT

City licenses. Some Arizona cities require a general business license for home businesses and some don't. Phoenix, for example, has no general business license. Tucson, Mesa, Scottsdale, and many others do. See our Arizona business license guide for how to check.

TPT (Arizona's sales-tax-style tax). A.R.S. § 42-5061(A)(1) excludes from the retail classification "professional or personal service occupations or businesses that involve sales or transfers of tangible personal property only as inconsequential elements." ADOR's Model City Tax Code guidance gives a parallel example from hair salons: product used on a client during the service is usually inconsequential, but a bottle of product the customer takes home is a taxable retail sale. (A.R.S. § 42-5061; ADOR Model City Tax Code, Retail sales: professional services.)

In practice:

• Walking, sitting, boarding, or grooming fees: generally not subject to retail TPT. We found no ADOR ruling that names pet care specifically, so confirm with ADOR if you're unsure.
• Selling shampoo, treats, toys, collars, or leashes: retail sales. You need a TPT license from ADOR (the state charges $12 per location, plus any city fee), and you file returns. (ADOR TPT License.)
• Keep service and product income separate in your books and on invoices.

Our Arizona TPT License guide explains registration and filing.

Step 5: Federal and Arizona income tax

• You're self-employed if you work for yourself or take jobs through an app that treats you as an independent contractor. Report income and expenses on Schedule C. (IRS.)
• Self-employment tax (Social Security and Medicare) is generally owed if your net self-employment earnings are $400 or more. (IRS.)
• All income is taxable whether or not you get a 1099. Apps and payment processors send Form 1099-K only above IRS thresholds; clients who pay you directly may not send anything. Track every payment.
• Common deductions: business mileage (driving between clients), supplies, grooming equipment, a portion of your phone, insurance, and platform fees. Keep a mileage log.
• Arizona income tax: your side-hustle profit is also taxed by Arizona.

See Side Hustle Taxes in Arizona for quarterly estimates, 1099 thresholds, and mileage rates, or use the Arizona side hustle tax calculator to estimate what to set aside.

Insurance, contracts, and safety (no license, still risky)

These aren't legal requirements we found for solo pet sitters, but they're worth deciding on deliberately:

• Liability coverage. Ordinary homeowners or renters policies may exclude business activity or "care, custody, or control" of other people's animals. Ask your insurer in writing.
• A written service agreement covering emergency vet authorization, who pays vet bills, key handling, and cancellation.
• Vaccination records. Ask owners for current rabies vaccination records; Arizona counties require dogs to be vaccinated and licensed. (Pima County Code § 6.04.070.)
• Heat. Arizona pavement can burn paws in summer. Schedule walks for early morning or evening and carry water.
• Hiring help. Once you hire employees, Arizona requires workers' compensation coverage. (Industrial Commission of Arizona.)

Common questions

Do I need a license to be a pet sitter in Arizona? We found no state license for pet sitting or dog walking. You may still need a city business license, and boarding five or more dogs at your home can trigger a county kennel permit. Confirm with your city and county.

Do I need a license to groom dogs in Arizona? No state groomer license exists that we could find. Some counties permit grooming facilities, and Phoenix zoning doesn't allow dog grooming as a home occupation.

Is dog grooming taxable in Arizona? The grooming service itself generally isn't subject to retail TPT when products used are inconsequential. Products you sell to customers are taxable. Confirm with ADOR.

How many dogs can I board at my house? At five or more dogs on the property, check the county kennel permit rule. City zoning, HOA rules, and noise ordinances may set tighter limits.
