TL;DR
Adult foster care service is small-home, family-style residential care for adults who need help with daily activities but not skilled nursing. Usually 1 to 6 residents, licensed by state health or human services agencies. Medicare doesn't pay for room and board in these settings; Medicaid may cover care costs through state waivers, confirm with your state licensing agency for specifics.
What is adult foster care service?
Adult foster care (sometimes called adult family care, adult family homes, or family-style residential care depending on the state) is a licensed living arrangement where a small number of adults, usually somewhere between 1 and 6, live in a home setting and receive help with daily activities from a live-in or on-site caregiver. It sits between fully independent living and a nursing facility. Think of it as the residential care version of foster care for children, except the residents are adults who need supervision, help with bathing, dressing, medication reminders, meals, and household support, not skilled medical treatment. States use different names for basically the same model. Oregon calls it "adult foster home," Michigan calls it "adult foster care facility," Massachusetts and a handful of others call it "adult family care," and some states fold it into a broader "residential care facility" or "assisted living facility" category. The core idea holds everywhere: a private home, a small resident count, and a caregiver who lives on-site or nearby. Michigan's licensing statute defines an adult foster care facility as "a governmental or nongovernmental establishment that provides foster care to adults" and covers homes serving anywhere from 1 to 20 or more residents depending on license type, though most homes are small [1]. Oregon's rules cap most adult foster homes at 5 residents unless the operator holds a specific larger-capacity license [2]. That size cap is the defining feature that separates adult foster care from a bigger assisted living facility down the street. If you're comparing models, our guide to assisted living facilities walks through how larger licensed operations differ in staffing ratios and building code requirements.
What is assisted living?
Assisted living is a broader category of residential care for adults, typically seniors, who need help with daily activities like bathing, dressing, medication management, and meals, but don't need the round-the-clock skilled nursing care of a nursing home. Assisted living facilities range from small homes with a handful of residents to large campuses with over a hundred units. CMS describes assisted living and similar residential care settings as part of the home and community-based services spectrum, meaning care delivered outside of an institutional nursing facility [3]. The specific services included in a state's assisted living license vary widely. Some states require licensed assisted living facilities to offer medication administration by trained staff; others limit staff to medication reminders only, pushing actual administration to a licensed nurse or the resident themselves. Assisted living is regulated at the state level, not federally, so the term itself has no single legal definition nationwide. That's part of why terminology gets confusing fast: what one state licenses as "assisted living" another state licenses as "residential care facility" or "personal care home." If you're building out a facility rather than a small foster-style home, our assisted living facility guide breaks down the licensing steps state by state.
What is a group home?
A group home is a licensed residential setting where a small number of unrelated people live together and receive support services, most often people with intellectual or developmental disabilities, mental illness, or substance use recovery needs, though the term also gets used loosely for senior residential care. Group homes are usually actual houses in residential neighborhoods, staffed by direct support professionals rather than nurses. The legal and regulatory line between "group home," "adult foster care," and "assisted living" is genuinely blurry and depends entirely on which state agency licenses the population you're serving. A home for adults with IDD might be licensed under a state's developmental disabilities division. A home for seniors needing help with daily activities might be licensed under the same agency that licenses assisted living facilities, sometimes even under the exact same rule set as adult foster care. Confirm with your state licensing agency which category actually applies to the population and services you plan to offer, because applying under the wrong license type can mean starting the paperwork over from scratch.
What is an assisted living facility (and what's the difference from adult foster care)?
| Typical resident count | 1 to 6 | Often 16 to 120+, varies by state | |
|---|---|---|---|
| Setting | Private home, residential neighborhood | Purpose-built facility or converted large home | |
| Staffing model | Live-in or on-site caregiver, sometimes the home operator themselves | Shift-based staff, administrator, often nursing oversight | |
| Licensing agency | Often same agency as ALF, sometimes a separate "foster care" division | State health or aging/long-term care agency | |
| Building code | Residential code in many states | Often commercial/institutional code above a resident threshold | That resident-count threshold matters enormously for your building code and fire marshal review. Many states trigger commercial building code requirements once you cross a specific occupant number, which can mean sprinkler systems, wider hallways, and different exit requirements. Confirm the exact threshold with your state licensing agency and local fire marshal before you sign a lease or buy property, because retrofitting a home for commercial fire code after the fact is expensive and sometimes impossible on that particular lot. Our zoning and property resources cover this in more depth if you're still shopping for a location. |
An assisted living facility is the licensed building or program itself, the physical structure and its state license, as opposed to "assisted living" the general concept of the care model. The facility license spells out things like maximum resident capacity, staffing ratios, physical plant requirements (sprinklers, exits, room sizes), and the specific services staff are allowed to provide. The practical difference from adult foster care usually comes down to three things: size, setting, and staffing structure. | Feature | Adult foster care | Assisted living facility |
What is assisted living vs nursing home, and how is adult foster care different from both?
Assisted living and nursing homes both provide residential care, but they sit at different points on the acuity spectrum, and adult foster care sits below both in most states' regulatory hierarchy. A nursing home (also called a skilled nursing facility) provides 24-hour nursing care from licensed nurses, handles residents with significant medical needs, wound care, IV therapy, rehabilitation after surgery or hospitalization, and is regulated under federal Medicare and Medicaid nursing home requirements found in 42 CFR Part 483 [4]. Nursing homes must have a registered nurse on duty at least 8 consecutive hours a day, 7 days a week, under federal requirements, with licensed nursing coverage 24 hours a day [4]. Assisted living has no equivalent federal nursing staffing mandate. It's licensed purely at the state level, and requirements for nurse involvement vary from "none required" to "must have an RN consultant" to "must have licensed nurse on staff" depending on the state and the acuity of residents the facility accepts. Adult foster care sits below assisted living in most states' acuity ladder: it's meant for people who need help with daily living, supervision, and a family-style setting, but not skilled nursing and often not the level of medical complexity a larger assisted living facility is licensed to handle. If a resident's needs escalate to requiring skilled nursing care, most adult foster care and assisted living licenses require the operator to either bring in additional licensed support or help the resident transition to a nursing facility. That escalation trigger is usually written into the state's regulations as a "negotiated risk agreement" or "discharge criteria" section, and it's one of the first things an inspector checks during a survey.
What does assisted living provide (and what does adult foster care actually provide day to day)?
Assisted living and adult foster care both typically provide a defined bundle of non-medical support services, though the exact list is set state by state and often spelled out in the facility's individual service plan for each resident. Common services across both models include help with activities of daily living (bathing, dressing, toileting, transferring, eating), medication reminders or administration depending on staff licensure, three meals a day plus snacks, housekeeping and laundry, transportation to medical appointments, and some level of social or recreational activity. Some states require a written individual service plan or care plan for every resident, updated on a set schedule (often every 6 to 12 months or whenever a resident's condition changes materially). What assisted living and adult foster care generally do NOT provide, unless the specific license type allows it, is skilled nursing care, IV therapy, ventilator support, or care for residents who are bedbound and require two-person transfers, though some states have a higher-acuity "enhanced" or "expanded" license tier that permits more of this. Confirm with your state licensing agency exactly which services your license tier permits before you accept a resident whose needs might exceed it, because accepting someone above your licensed acuity level is one of the most common citations inspectors write up, and in serious cases it can trigger an involuntary discharge requirement or a licensing complaint.
Does Medicare cover assisted living facilities or adult foster care?
No. Medicare does not cover room and board or the custodial care provided in assisted living facilities or adult foster care homes. Medicare.gov states plainly that Medicare does not pay for "custodial care, if it's the only care you need" and defines custodial care as help with daily activities like bathing, dressing, and using the bathroom [5]. Medicare Part A can cover a short-term skilled nursing facility stay after a qualifying hospital stay, and Medicare will still cover medical services a resident receives while living in assisted living or adult foster care, things like doctor visits, physical therapy, or home health visits ordered by a physician. But the monthly cost of living in the facility itself, the rent-and-care-bundle, is not a Medicare-covered expense anywhere in the country. Medicaid is a different story, and this is where most of the funding conversation actually happens. Many states cover assisted living and adult foster care services (not room and board, but the care component) through Medicaid Home and Community-Based Services (HCBS) waivers authorized under Section 1915(c) of the Social Security Act [6]. Medicaid.gov describes these waivers as letting states "provide long-term care services in home and community settings rather than institutional settings" . Coverage, eligibility, and which specific settings qualify vary enormously by state, so confirm with your state Medicaid agency and licensing agency which waiver programs, if any, apply to the population and setting you're licensing. Our funding and Medicaid hub goes deeper on how waiver reimbursement actually works for operators.
How to start a group home (the licensing sequence)
Starting a group home or adult foster care home follows a fairly consistent sequence across states, even though the specific forms, fees, and agency names differ. Here's the order that actually works, based on how state licensing statutes are structured: 1. Identify the correct license category first. Confirm with your state licensing agency whether the population you want to serve (seniors needing ADL help, adults with IDD, mental health, or recovery) falls under adult foster care, assisted living, or a separate group home license. This single decision determines every form and rule that follows. 2. Check zoning before you sign anything. Many states have specific statutory language protecting small group homes (often 6 or fewer residents) from being treated as a commercial use under local zoning, similar to protections found in the federal Fair Housing Act's reasonable accommodation provisions . But local interpretation varies, and you still need a zoning verification letter from the municipality before you commit to a property. 3. Complete required training and background checks for yourself and any staff, which typically include a criminal history background check and sometimes a state abuse/neglect registry check, required before an application is even accepted in most states. 4. Submit the license application with the required fee. Fees range widely; confirm the current fee schedule with your state licensing agency rather than relying on outdated figures found online. 5. Pass a pre-licensing inspection covering fire safety, physical plant condition, and program readiness (staffing plan, policy manual, emergency procedures) before the state issues the initial license. 6. Develop your policy and procedure manual, staffing plan, and admission/discharge criteria, all of which the inspector will review against the specific licensed capacity and acuity level you're applying for. Building your own policy manual and forms from scratch for a first-time license application typically means either hiring a consultant, which can run into the thousands of dollars, or piecing together templates from your state's own published rule and hoping you interpreted the requirements correctly. That's the gap we built the $299 State Group Home Licensing Kit to close: state-specific application checklists, policy manual templates, and staffing plan documents built around your state's actual licensing rule, at a fraction of what a licensing consultant charges. It's not a shortcut around the inspection or the state's own review, nobody can promise you approval, but it removes the guesswork of building your paperwork from a blank page.
How do I start a group home if I've never run a business before?
If you've never run a licensed care business before, the honest first step is a phone call, not a purchase or a lease signing. Call your state licensing agency's group home or adult foster care division and ask for the specific rule citation covering your intended population. Every state publishes this; some make it easy to find, some bury it in an administrative code you'll need help decoding. From there, the practical sequence is: confirm zoning eligibility for the specific address you're considering, get pre-qualified or budgeted for the property (buy or lease, most lenders and landlords want to see your license application in progress or approved before they'll finalize anything for a care-use property), complete any state-required orientation or pre-licensing training, and build your operational documents (policies, staffing plan, emergency plan, admission agreement) in parallel so you're not starting that work the week before your inspection. A realistic first-year budget needs to account for the license application fee itself, background check fees for you and staff, any required CPR/first aid certification, property modifications to meet fire and physical plant code, and enough working capital to cover the gap between your first residents moving in and your first Medicaid or private-pay reimbursement actually arriving, which can take 60 to 90 days or longer in some state Medicaid systems. Confirm actual timelines with your state Medicaid agency, since payment processing speed varies by state and by waiver program.
What is the difference between assisted living and nursing home staffing and inspections?
Nursing homes face federal survey requirements under 42 CFR Part 483, conducted by state survey agencies on behalf of CMS, typically on a cycle that must occur no less frequently than every 15 months, with a statewide average interval of 12 months or less [4]. These surveys are exhaustive: they cover clinical care, medication administration, resident rights, food service, and physical plant, often over multiple days with a team of surveyors. Assisted living and adult foster care inspections are state-specific, not federally mandated, and vary widely in scope and frequency, sometimes annual, sometimes tied to license renewal cycles of 1 or 2 years, sometimes triggered by complaints rather than a fixed calendar. Confirm your state's specific inspection frequency and scope with your licensing agency, since this is one of the areas where state rules diverge the most. What stays consistent everywhere: inspectors check whether actual staffing matches what's on your approved staffing plan, whether resident records match what's required (service plans, medication logs, incident reports), and whether the physical building still meets the fire and life safety code it was licensed under. Our inspections hub has state-specific inspection prep checklists if you want to see what surveyors actually look for room by room.
Frequently asked questions
What is assisted living?
Assisted living is a state-licensed residential care model for adults who need help with daily activities like bathing, dressing, and medication management but don't need full-time skilled nursing care. Facilities range from small homes to large campuses. There's no single federal definition; each state sets its own licensing rules, staffing requirements, and services covered under the assisted living label.
What is a group home?
A group home is a licensed residential setting where a small number of unrelated adults live together and receive support services, commonly serving people with intellectual/developmental disabilities, mental illness, or substance recovery needs. It's usually a house in a residential neighborhood staffed by direct support professionals. The exact licensing category depends on which state agency oversees the population served.
What is an assisted living facility?
An assisted living facility is the specific licensed building and program providing assisted living services, as opposed to the general care concept. The facility license sets maximum resident capacity, staffing ratios, physical plant standards, and which services (like medication administration versus reminders only) staff are authorized to provide under that state's rules.
What is assisted living facility, in plain terms?
It's a licensed home or building where seniors or adults needing help with daily activities live and receive support with things like bathing, dressing, meals, and medication reminders, without the round-the-clock nursing care of a hospital or nursing home. Size ranges from small residential homes to facilities with over a hundred units, depending on the state and license type.
What is assisted living vs nursing home?
Assisted living provides non-medical daily living support in a residential setting, regulated at the state level with no federal nursing staff mandate. A nursing home provides 24-hour skilled nursing care and is federally regulated under 42 CFR Part 483, requiring registered nurse coverage at least 8 hours daily, 7 days a week, per CMS rules.
What does assisted living provide?
Typically help with bathing, dressing, toileting, and eating; medication reminders or administration depending on staff licensure; meals; housekeeping and laundry; transportation to appointments; and social activities. Exact services depend on state license tier and each resident's individual service plan, which most states require to be reviewed and updated periodically.
How do I start a group home?
Confirm the correct license category with your state licensing agency, verify zoning for your intended property, complete required background checks and training, submit the license application with fee, pass a pre-licensing inspection, and have a policy manual, staffing plan, and admission criteria ready before your inspection. The exact sequence and requirements are state-specific.
What is the difference between assisted living and nursing home costs and services?
Nursing homes provide skilled medical and rehabilitative care with 24-hour licensed nursing staff, for higher-acuity residents recovering from surgery or managing complex medical conditions. Assisted living provides non-medical daily living support for lower-acuity residents. Costs and coverage differ too: nursing home stays can qualify for short-term Medicare coverage after a hospital stay; assisted living generally does not.
Does Medicare cover assisted living facilities?
No. Medicare does not cover room and board or custodial care in assisted living facilities, per Medicare.gov, which explicitly excludes custodial care like help with bathing and dressing from coverage. Medicare will still pay for separate medical services a resident receives while living there, such as doctor visits or physical therapy ordered by a physician.
How do I start a group home if I've never done it before?
Start with a phone call to your state licensing agency to get the specific rule for your intended population. Then confirm zoning for your property, budget for application fees, background checks, and physical plant upgrades, and build your policy manual and staffing plan in parallel with the application so you're ready for the pre-licensing inspection.
Does Medicaid pay for adult foster care or assisted living?
Many states cover the care component (not room and board) of assisted living or adult foster care through Medicaid Home and Community-Based Services waivers under Section 1915(c) of the Social Security Act. Coverage and eligible settings vary by state, so confirm current waiver programs and eligibility with your state Medicaid agency.
What's the maximum number of residents in adult foster care?
Most states cap adult foster care homes between 1 and 6 residents, keeping the setting family-style rather than institutional. Some states allow larger licensed capacities under different license tiers or facility types. Confirm your state's specific resident cap with the licensing agency before selecting or leasing a property.
Is a group home the same as assisted living?
Not always. Both are licensed residential care settings, but "group home" often refers to homes serving people with disabilities or mental health needs, while "assisted living" typically refers to senior care. Some states use overlapping or identical licensing rules for both; others license them under entirely separate divisions and statutes.
