A foster adult is a person age 18 or older who lives in someone else’s licensed private home and receives daily personal care, supervision, and support from a resident caregiver. The arrangement goes by different names in different states, including adult foster care, adult family care, and domiciliary care, but the structure is consistent: a small household, usually one to six residents, where adults who cannot safely live alone get around-the-clock help in a family setting rather than an institutional one.
The term describes the person receiving care, not the person providing it. A foster adult has their own bedroom and shares kitchens, living rooms, and meals with the caregiver’s household. The help is personal rather than medical, covering things like bathing, dressing, eating, moving around, and managing medications. Someone who needs continuous skilled nursing, ventilator support, or constant medical monitoring is not a candidate, because these homes are not licensed or equipped for clinical care at that level.
Who Qualifies as a Foster Adult
Eligibility turns on a single question: can this person live safely on their own? A social worker screens each applicant, and the threshold is a documented functional impairment, meaning a physical, developmental, cognitive, or mental health condition serious enough to interfere with self-care. Trouble walking, significant vision or hearing loss, intellectual disabilities, and chronic mental illness all count when they prevent someone from managing daily routines independently.
The people who most often become foster adults fall into a few groups:
- Elderly adults who need help with personal care but do not require hospital-level nursing.
- Adults with developmental disabilities who have aged out of the child welfare system.
- People with chronic physical conditions such as advanced arthritis, stroke aftereffects, or progressive neurological disease.
- Adults with serious mental health conditions whose symptoms make independent living unsafe.
Screening also considers risk of abuse, neglect, or exploitation. Someone who could technically perform daily tasks but lives in an environment where they are being harmed or taken advantage of may still qualify.
What Life in an Adult Foster Home Looks Like
States license these homes under their own rules, and the terminology varies, but most recognize two basic models.
In the more common model, the licensed caregiver lives in the home and personally provides most of the day-to-day care. These are often called family adult foster care homes. The caregiver is a member of the household, shares living space with the residents, and is present overnight. Capacity is usually capped at six or fewer. This is where the family-style dynamic is strongest, and it is what most people picture when they hear the term.
The second model is a corporate or agency-run home where the license holder does not live on site. Paid staff work in shifts to provide 24-hour coverage. These homes sometimes serve a slightly larger number of residents, though they are still much smaller than a typical assisted living facility. The trade-off is less continuity with a single caregiver in exchange for more structured staffing.
Either way, licensing requires the home to meet safety standards, pass inspections, and maintain an individualized care plan for each resident.
How It Differs From Assisted Living and Nursing Homes
The clearest differences come down to size, staffing, and feel. Adult foster care homes are small private residences with a handful of residents. Assisted living facilities can house dozens or hundreds of residents in purpose-built complexes with shared hallways, activity rooms, and commercial kitchens. In a foster home, you eat dinner at the family table. In assisted living, you eat in a dining hall.
The staffing model is also fundamentally different. Adult foster care relies on a primary caregiver who often lives in the home and knows each resident well. Assisted living uses rotating shift staff across departments. Neither setting provides continuous skilled nursing, though both can arrange for outside home health or hospice services to visit residents who need them.
Cost reflects the difference in scale. Adult foster care typically runs between $2,000 and $5,000 per month, roughly half the cost of nursing home care and generally less than assisted living. The exact price depends on location and the resident’s care needs.
Paying for Adult Foster Care
A common misconception is that adult foster care is only for people who can pay out of pocket. Several public programs help cover the cost, though none make it completely free.
Medicaid Home and Community-Based Services Waivers
The main public funding source is Medicaid, specifically Home and Community-Based Services (HCBS) waivers authorized under Section 1915(c) of the Social Security Act. These waivers let states use Medicaid dollars to pay for care in community settings, including adult foster homes, as an alternative to nursing home placement. The statute requires states to show that waiver participants would otherwise need institutional care and that the per-person cost does not exceed what institutional care would have cost.1Social Security Administration. Social Security Act 1915 Covered services can include personal care, case management, respite care, and adult day health.2Medicaid.gov. Home and Community-Based Services 1915(c)
One important limit: HCBS waivers do not cover room and board. The resident pays for their own housing and food, and the waiver pays for the care services on top. Waivers are also not entitlements. States cap the number of participants, and waiting lists are common.
Supplemental Security Income
Many foster adults receive Supplemental Security Income, which pays an eligible individual a monthly federal amount of $994 in 2026.3Social Security Administration. SSI Federal Payment Amounts Some states add a supplement on top. SSI often goes directly toward the resident’s room and board, with Medicaid waiver funds covering the care itself. SSI benefits can be reduced when a recipient lives in another person’s household and pays less than a fair share of housing costs.
VA Medical Foster Homes
Veterans who need nursing-home-level care but prefer a smaller setting may qualify for the VA’s Medical Foster Home program. These are privately owned homes approved by the VA as a non-institutional alternative to VA nursing home placement. Veterans typically pay their caregivers between $1,500 and $3,000 per month depending on location. Veterans receiving Aid and Attendance benefits can apply that money toward foster home costs.
Rights the Resident Keeps
Moving into a foster home does not strip anyone of their civil rights. Protections vary by state but generally include the right to privacy, the right to manage personal finances or choose a trusted person to help, the right to receive visitors, and the right to be free from physical, verbal, and emotional abuse. Residents can file complaints without fear of retaliation, and caregivers are required to report suspected abuse to state authorities.
The federal Long-Term Care Ombudsman Program, authorized under the Older Americans Act, adds an independent layer of consumer protection for people living in care settings, including adult foster homes.4Administration for Community Living. Long-Term Care Ombudsman Program Ombudsmen investigate complaints, advocate for residents, and mediate disputes. Anyone can contact the program, not just the resident. Family members, friends, and even facility employees can raise concerns, and complaints stay confidential unless the person filing gives permission to share.
Finding a Licensed Home
The fastest starting point is the Eldercare Locator, a free service run by the U.S. Administration for Community Living. You can call 800-677-1116 (Monday through Friday, 8 a.m. to 9 p.m. Eastern) or visit eldercare.acl.gov to search by zip code.5Administration for Community Living. Eldercare Locator The Locator connects callers to their local Area Agency on Aging, which can refer you to licensed adult foster care providers, explain state-specific eligibility rules, and help with Medicaid waiver applications.
Your state’s department of health or human services also maintains a directory of licensed adult foster homes. Those agencies handle licensing, inspections, and complaint investigations, so they are the authoritative source for confirming whether a specific home is in good standing. If you are looking on behalf of a veteran, contact the VA’s social work service directly about the Medical Foster Home program in your area.
