Most families I work with come to me knowing that their parent needs more help than they can provide at home, but uncertain about what kind of setting makes sense. The terms "assisted living," "memory care," and "board-and-care home" are sometimes used interchangeably — but in Arizona they refer to meaningfully different settings that serve different needs at different costs. Getting the setting right the first time matters: a move to the wrong type of community creates trauma for the resident and an expensive second placement six months later.
Three settings, three distinct models
All three settings provide housing and personal care assistance. What distinguishes them is staff ratio, physical environment, programming, and the care needs they are designed to meet.
An assisted living facility (ALF) is the broadest category — a licensed residential care setting for seniors who need help with daily activities but do not need continuous skilled medical supervision. A memory care unit is a specialized section of an ALF (or a standalone facility) designed specifically for residents with Alzheimer's disease, dementia, or other cognitive conditions. A board-and-care home (called an "Assisted Living Home" in Arizona statute) is a small residential setting — typically in a single-family house — for up to 10 residents.
Assisted living facilities (ALFs)
Arizona's ALF statute (ARS Title 36, Chapter 4) defines assisted living as a setting that provides personal care services, supervisory care services, or directed care services to residents who need help with ADLs but whose conditions are stable. ALFs range from small boutique communities of 20 to 30 residents to large multi-story buildings with 150 to 200 residents and full amenity packages: dining rooms, activity programming, fitness centers, salons, and scheduled transportation.
Who belongs in an ALF: a senior who needs help with bathing, dressing, medications, and meals; who is ambulatory or uses a walker or wheelchair for independent mobility; whose medical conditions are managed and stable; and who would benefit from a social environment with organized programming. ALFs are not appropriate for residents who wander without awareness of danger, who have severe behavioral symptoms from dementia, or who require continuous skilled nursing oversight.
ALF environments are open — residents can generally move freely within the building and often into outdoor spaces. This is a feature for cognitively intact residents and a liability for residents with dementia-related wandering or elopement risk. If your parent has been found outside at night, has gotten lost driving, or has attempted to leave settings they should not leave, an open ALF is not safe.
Memory care units
Memory care units are purpose-designed for residents with dementia: secure perimeters, simplified environments, higher staff ratios, and activity programming adapted to cognitive impairment. In Arizona, standalone memory care facilities are licensed as "Behavioral Health Residential Facilities" or as specialized ALFs under ADHS guidelines. Most large ALF campuses in Phoenix have a memory care wing operating under the same license with different programming.
The physical differences between an ALF and a memory care unit are significant. Memory care units use secured access — door codes, keypad locks, or magnetic sensors — to prevent elopement. Corridors are often designed in loops so that wandering residents return to where they started rather than reaching an exit. Common areas are smaller and less stimulating. Staffing ratios are higher, typically one caregiver to four or five residents versus one to seven or eight in a standard ALF.
Who belongs in memory care: a senior with a confirmed dementia diagnosis whose cognitive impairment creates safety risks — wandering, inability to manage medications, inability to recognize danger in everyday situations, significant behavioral symptoms (agitation, aggression, sun-downing), or inability to follow simple directions consistently. The triggering event is usually a safety incident at home or in a less-secure setting, not just a diagnosis. See our guide on signs it's time for memory care in Arizona for the specific triggers I look for.
Board-and-care and assisted living homes
Arizona licenses small residential care settings — typically 4 to 10 residents in a single-family home — as "Assisted Living Homes" under ARS Title 36. These settings are commonly called board-and-care homes, residential care homes, or care homes. They operate in real neighborhoods, not institutional campuses, and provide a more intimate, family-like environment.
The main advantages of a board-and-care home in Phoenix: better staff-to-resident ratio (often one caregiver per three or four residents in a 6-bed home), more personalized attention, quieter environment, and often lower cost than a large ALF for equivalent care. The main limitation: no large-group programming, limited social environment for socially active seniors, and no on-campus amenities. For a resident who was independent and socially active before needing care, a large ALF with an active social calendar is often a better fit. For a resident who is quieter, prefers a small household, or has high one-on-one care needs, a board-and-care home frequently delivers better quality of life per dollar spent.
ADHS licenses and inspects Assisted Living Homes under the same regulatory framework as larger ALFs — the ADHS Care Check portal shows inspection history for both. Some board-and-care homes in Phoenix are ALTCS-participating; this varies by specific home and MCO contract.
2026 cost comparison in Phoenix
- Assisted living facility (base): $3,800 to $6,500/month + level-of-care surcharge ($250 to $2,200/month)
- Memory care unit (base + premium): $5,500 to $9,200/month
- Board-and-care / Assisted Living Home: $3,000 to $5,800/month (typically all-inclusive; fewer add-on fees)
Board-and-care homes often have a simpler fee structure — one monthly rate that includes care, meals, housekeeping, and laundry — with fewer of the itemized add-ons (medication management fees, transportation, supply charges) that inflate the effective monthly cost at larger ALFs. When comparing apples to apples, a $4,500/month board-and-care home with one all-in rate frequently costs less than a $4,200/month ALF with $800/month in add-ons.

Decision framework: which setting fits?
When I assess a placement for a Phoenix family, I use three questions to determine the right setting type:
1. Is there a safety risk from cognitive impairment? If yes — wandering, inability to recognize danger, severe behavioral symptoms, repeated unsafe decisions — memory care is the right starting point. An ALF that accepts memory-impaired residents may be an interim option, but a purpose-built memory care unit provides the environmental design and staffing that prevents the incidents that end placements.
2. How high are the one-on-one care needs? For residents who need two-person transfers, full incontinence care, and significant cueing for every ADL, the staff ratios in most large ALFs are not designed for that level of need — their Level 3 or Level 4 tier is often the edge of what they can deliver safely. Board-and-care homes with a 1:3 or 1:4 ratio can sometimes meet higher physical care needs at a lower cost than a large ALF at its highest tier.
3. What social environment does the resident need? A senior who was active, social, and engaged before needing care typically does better in a large ALF with organized activities, meal dining, and peer interaction. A senior who is quieter, introverted, or overwhelmed by noise and group settings typically does better in a board-and-care home. This dimension is underweighted in most family conversations — care type and cost dominate — but it drives quality of life as much as either.
When to move between settings
Placements are not permanent in most cases. The most common moves I see in Phoenix: from an ALF to memory care when dementia progresses, from a board-and-care home to an ALF when the resident needs more programming or when the home can no longer meet care needs, and from any community setting to skilled nursing when medical complexity requires licensed nursing supervision.
The triggers that prompt a move from ALF to memory care: elopement attempts or exits from the facility, significant sundowning that disrupts other residents, agitation or aggression the ALF staff cannot safely manage, inability to follow safety directions, and repeated falls that the current environment and staffing cannot prevent. The move is difficult for families — it often feels like a deterioration — but the right memory care environment frequently stabilizes behavioral symptoms and reduces fall risk.
How ALTCS intersects with setting type
ALTCS covers all three setting types at participating providers. In practice, ALTCS participation rates vary: more board-and-care homes and mid-market ALFs in the West Valley participate than luxury ALFs in Scottsdale. Standalone memory care communities have lower ALTCS participation rates than general ALFs, though this is improving as MCO contracts expand. If ALTCS is a current or near-term funding source, ask every community you tour whether they have active ALTCS contracts with all three MCOs, and what the current waitlist looks like for ALTCS-funded beds specifically.
Our placement advisors know which Phoenix-area communities currently have ALTCS openings by care type and MCO. Contact us for a free consultation — we can typically narrow the list to three to five strong matches within a few days.
