Assisted living center vs. assisted living home in Arizona

Last verified: October 2026

What is the difference between an assisted living center and an assisted living home in Arizona?

The only legal difference is size: under A.R.S. 36-401 an assisted living center provides rooms or residential units to eleven or more residents, while an assisted living home provides rooms to ten or fewer. Both are assisted living facilities licensed by the Arizona Department of Health Services and both follow the same rules in Arizona Administrative Code Title 9, Chapter 10, Article 8.

Either size can be licensed for any of the three service levels, supervisory, personal or directed care. In daily life the difference is bigger than the statute suggests: a home is usually a converted house with one kitchen and a handful of caregivers, while a center is a purpose-built building with a dining room, activity staff and often a wellness nurse.

How many assisted living centers and homes are licensed in Pima County?

AZ Care Check listed 53 active assisted living centers and 257 active assisted living homes in Pima County on October 30, 2026. The homes outnumber the centers almost five to one, but the centers hold more beds: 4,919 against 2,447.

The median Pima County center is licensed for 91 residents, and 220 of the 257 homes are licensed for the maximum ten. The homes cluster in northwest, east and midtown Tucson; centers are spread more evenly, with groups in the Catalina Foothills, Oro Valley and Green Valley. See both lists in the directory.

Is an assisted living home safer or cheaper than a center?

Neither is automatically safer or cheaper. Small homes often quote one all-inclusive monthly rate and can offer more one-to-one attention, while centers usually charge a base rent plus care-level fees; safety depends on staffing, training and the inspection record rather than the license size.

Two questions separate them in practice. First, the residency agreement for an assisted living home must state whether the manager or a caregiver is awake during nighttime hours, so ask to see that clause. Second, compare the inspection history on AZ Care Check: a long run of clean annual inspections says more than square footage.

Which should you choose for a parent in Tucson?

Choose a center when a parent wants social life, structured activities and on-site amenities, and a home when a parent does better in a quiet household with the same few caregivers every day, which is common with moderate dementia or anxiety in crowds.

Families often tour one of each. Watch how staff speak to residents, whether residents are up and engaged mid-morning, and how meals are served. Then check both on AZ Care Check before you sign anything.

Do the same Arizona rules apply to both sizes?

Yes. Centers and homes are licensed under the same article of the Arizona Administrative Code, so the rules on residency agreements, service plans, medication, resident rights, manager certification, caregiver training and termination notice are the same.

The differences that do exist are practical. Building and fire-safety requirements scale with size and occupancy, and the agreement disclosure about whether someone is awake at night is required of homes specifically. A manager can run only the facility named on its license, so small homes usually have a manager who is on site much of the day.
