Memory Care vs Assisted Living: Costs, Differences and a Third Option

“Does Mom need memory care or assisted living?” It is one of the most common questions San Diego families ask us, and one of the most important. Choosing the wrong setting can mean a stressful second move a few months later. Understanding memory care vs assisted living, and a third option many families have never heard of, makes the decision much clearer.

This guide explains the real differences between memory care and assisted living, introduces small dementia board and care homes, compares 2026 costs in San Diego, and gives you a simple way to decide which setting fits your loved one now and in the future.

Memory Care vs Assisted Living: The Short Answer

Assisted living is for seniors who need help with daily activities such as bathing, dressing, medications and meals, but who can generally find their way around, follow a routine and stay safe in an open building.

Memory care is for seniors with Alzheimer’s disease or another dementia whose memory loss affects their safety. Memory care is secured so residents cannot wander away, and staff have specialized dementia training.

Dementia board and care homes are small, licensed homes with about 6 residents that provide memory care in a regular house. For many people with moderate to advanced dementia, they are the best fit of the three.

What Is Assisted Living?

An assisted living community helps seniors with activities of daily living: bathing, dressing, toileting, grooming, moving from place to place and taking medications. It also handles meals, housekeeping, laundry, activities and often transportation. Residents usually live in private apartments and share a dining room, common areas and a full activity calendar.

In California, assisted living communities are licensed by the Department of Social Services as Residential Care Facilities for the Elderly (RCFEs). That license sets what care they can and cannot provide. An assisted living community generally cannot accept residents with dementia who need a secured setting unless it meets extra requirements for staff training, safety and programming.

Assisted living works well for seniors who are social, mostly oriented and able to use the call system, find the dining room and recognize their own apartment. Many residents have mild memory loss or mild cognitive impairment (MCI) and do fine in assisted living, sometimes for years.

What Is Memory Care?

Memory care, also called dementia care or Alzheimer’s care, is assisted living designed specifically for people with dementia. In other words, memory care is a form of assisted living with extra rules and protections. It shows up in two main forms in San Diego:

• A memory care wing or neighborhood inside an assisted living community, separated and secured from the rest of the building
• A stand-alone memory care community that cares only for residents with dementia

Either way, memory care must meet additional California requirements, including:

• Secured exits. Delayed-egress or locked doors and enclosed outdoor areas so residents who wander cannot leave unnoticed. These require state approval.
• Dementia training. Caregivers must complete dementia-specific training before and during employment.
• Structured programming. Activities matched to residents’ abilities, such as music, sensory activities, reminiscence and simple purposeful tasks.
• Safety planning. Individual plans for wandering, falls, behaviors and changes in condition.

Memory care is designed for people who wander or try to leave, get lost in their own building, are agitated or anxious, sundown in the afternoon, or can no longer manage their day without constant cues and supervision.

The Third Option: Small Dementia Board and Care Homes

Many San Diego families compare memory care vs assisted living without realizing there is a third choice. A board and care home is a small RCFE, usually a single-story house in a residential neighborhood licensed for 6 residents. You may also hear this kind of residential senior care called a senior care home, an elder care home or a home for elderly adults. Many board and care homes in San Diego specialize in dementia, and when they accept residents with dementia they must meet the same state dementia training and safety rules as larger memory care communities.

What a small dementia board and care home offers:

• Calm and quiet. No long hallways, crowded dining rooms or noisy activity rooms. For many people with dementia, less stimulation means less anxiety and agitation.
• More attention. Typically 1 to 2 caregivers for 6 residents during the day. A caregiver can see and hear every resident, which matters a great deal for someone who falls, wanders or cannot call for help.
• Consistent faces. The same few caregivers every day, which builds trust and reduces confusion.
• Home routine. Home-cooked meals at a kitchen table, a living room, a backyard. It feels like a home because it is one.
• Care through later stages. Many homes care for residents who no longer walk, need two-person transfers, or need hospice. With a hospice waiver, a resident can stay through the end of life.

Small dementia homes are often the best fit for seniors who have more advanced cognitive loss, especially those who have become non-ambulatory, who feel lost in a big building, or who no longer join group activities. Our family guide to board and care homes in San Diego explains how these homes work, and our post on life in a board and care home shows what a typical day looks like.

The trade-off is fewer amenities. A board and care home will not have a bistro, fitness center or bus outings. For an active senior with mild memory loss, that can feel too quiet. For a senior with moderate or advanced dementia, it is often exactly right.

Memory Care vs Assisted Living vs Board and Care: Side by Side

Size. Assisted living and memory care communities in San Diego range from a few dozen to a few hundred residents. Memory care wings are often 15 to 40 residents. Dementia board and care homes usually have 6.

Security. Assisted living is generally open. Memory care and dementia board and care homes use secured or alarmed exits approved by the state.

Staffing. Assisted living and memory care communities staff by building and shift, so each caregiver may cover many residents. Small board and care homes usually have 1 to 2 caregivers for 6 residents during the day.

Activities. Assisted living offers full calendars and outings. Memory care offers structured dementia programs. Board and care homes offer simple, home-based activities and lots of one-on-one time.

Best fit. Assisted living suits seniors who are mostly oriented and social. Memory care suits people with dementia who are mobile and do well with structured group programs. Board and care suits people with moderate to advanced dementia, high hands-on needs, or limited mobility.

Memory Care vs Assisted Living Costs in San Diego (2026)

Here is what families can expect in San Diego County in 2026:

• Assisted living: about $5,500 to $12,500 per month. Many communities charge a base rent plus care fees that rise as needs grow.
• Memory care: about $7,500 to $14,000 per month, usually with dementia care built into a higher rate.
• Small dementia board and care homes: about $6,000 to $9,500 per month, usually as one all-inclusive rate.

In every setting, a private room often costs $1,000 to $2,000 more per month than a shared room. Coastal areas such as La Jolla, Del Mar and Carlsbad cost more than inland areas such as El Cajon, Escondido or Spring Valley.

For seniors who need a lot of hands-on care, dementia board and care homes are often the most affordable of the three because care is included rather than added in tiers. Always ask what is included, how care levels are assessed, and what would make the rate go up.

How families pay. Medicare does not pay for assisted living, memory care or board and care. Most families use savings, income, home sale proceeds or long-term care insurance. Veterans and surviving spouses may qualify for the VA Aid and Attendance pension. Medi-Cal’s Assisted Living Waiver can pay the care portion in participating facilities for those who qualify, though spots are limited. See our 2026 San Diego senior care cost guide and our Medi-Cal eligibility guide for details.

How Care Homes Decide: Memory Care or Assisted Living?

You do not have to make this call alone. Care homes and communities decide whether a senior needs memory care in two ways.

The Physician’s Report (LIC 602A). Every California RCFE requires this form from your loved one’s doctor before move-in. The home pays close attention to the primary and secondary diagnoses and to whether the doctor notes dementia or mild cognitive impairment. Ask the doctor to complete it carefully and honestly, because it shapes which setting will accept your loved one.

An in-person assessment. The administrator or nurse will meet your loved one and ask questions to judge memory, orientation, judgment, behaviors and physical needs. Be candid about wandering, nighttime behavior, falls and agitation. Downplaying needs often leads to a failed move.

Will My Loved One Need Memory Care Later?

This is one of the hardest questions in senior care, and the honest answer is that it depends.

A senior in their late 80s or 90s with mild memory loss or MCI may never progress to needing full memory care. A senior in their 70s or early 80s who already has a primary diagnosis of Alzheimer’s or another dementia, even if mild today, is much more likely to need it within a few years.

If more care is likely, think about the next move now:

• Does the assisted living community have its own memory care, so a move would be down the hall instead of across town?
• Will a board and care home keep your loved one as dementia progresses, including through hospice?
• What specific behaviors or needs would trigger a required move?

Choosing a setting that can grow with your loved one can prevent a painful second transition. Our guide on what to do after a dementia diagnosis covers planning for each stage.

How to Decide Between Memory Care and Assisted Living

Ask these questions about your loved one:

• Do they wander, try to leave, or get lost in familiar places? (Points to memory care or a dementia board and care home.)
• Can they find their room, the dining room and the bathroom on their own? (If yes, assisted living may work.)
• Can they use a call button and ask for help when they need it?
• Do they enjoy groups and activities, or do crowds and noise upset them?
• Do they walk on their own, use a walker, or need help to transfer?
• Are there behaviors such as agitation, sundowning or refusing care?
• What is the monthly budget, and how long does it need to last?

A rough guide: mostly oriented and social points to assisted living. Mobile with dementia and needing secure structure points to memory care. Moderate to advanced dementia, high hands-on needs, limited mobility, or a need for calm points to a small dementia board and care home. Many families tour one of each, and the right choice usually becomes obvious within minutes of walking in.

Before any tour, check the facility’s licensing history in the CDSS Care Facility Search. Our guide to reading RCFE inspection reports shows what to look for. You can also explore memory care facilities in San Diego, assisted living in San Diego and board and care homes in San Diego.

Frequently Asked Questions About Memory Care vs Assisted Living

What is the main difference between memory care and assisted living?

Assisted living helps seniors with daily activities in an open community. Memory care adds secured exits, dementia-trained staff and structured programs for people whose dementia affects their safety. In California, both are licensed as Residential Care Facilities for the Elderly, but memory care must meet extra dementia rules.

Can someone with dementia live in assisted living?

Often yes, in the early stage, if they are mostly oriented, do not wander and can ask for help. As dementia progresses, many need a move to memory care or a dementia board and care home. Ask any community what would trigger a required move.

How much does memory care cost compared with assisted living in San Diego?

In 2026, assisted living in San Diego costs about $5,500 to $12,500 per month and memory care about $7,500 to $14,000. Small dementia board and care homes cost about $6,000 to $9,500. A private room often adds $1,000 to $2,000 per month.

What is a dementia board and care home?

It is a small licensed RCFE, usually a house with 6 residents, that specializes in caring for people with dementia. It must meet California’s dementia training and safety rules, and it offers a calm home setting with 1 to 2 caregivers for 6 residents during the day.

Is a board and care home better than memory care for dementia?

It depends on the person. Board and care homes are often better for people with moderate to advanced dementia, limited mobility or high hands-on needs. Larger memory care communities can suit people who are mobile and enjoy group programs.

How do care homes decide if my parent needs memory care?

They review the Physician’s Report (LIC 602A), especially the diagnoses and any note of dementia or mild cognitive impairment, and they assess your parent in person. Be honest about wandering, behaviors and night needs so your parent is placed safely.

Does Medicare pay for memory care?

No. Medicare does not pay for assisted living, memory care or board and care. Families use private funds, long-term care insurance, VA benefits, or Medi-Cal’s Assisted Living Waiver where available.

When should we move from assisted living to memory care?

Common signs include wandering or trying to leave, getting lost in the building, missing meals or medications despite reminders, increased agitation or sundowning, and falls. The community will often raise the issue first, but you can ask for an assessment at any time.

Is Elder Answers free to use?

Yes. Elder Answers is paid by the care home after a resident moves in, so families never pay us. Our fee does not change the rate you pay the home.
