TL;DR

An assisted living facility is a state-licensed residence that provides housing, meals, and help with daily activities like bathing, dressing, and medication for people who don't need round-the-clock skilled nursing. There's no single federal definition. Each state sets its own rules, license category name, staffing minimums, and resident limits, so the exact meaning shifts depending on which state agency you ask.

What is assisted living?

Assisted living is a level of long-term care for adults who need help with daily activities but don't need the round-the-clock medical care a hospital or nursing home provides. Think bathing, dressing, medication reminders, meals, and someone checking on you regularly, not IV lines or ventilators. Here's the thing people get wrong constantly: there is no federal statute that defines "assisted living." Medicare and Medicaid regulate nursing homes and home health agencies through federal rules, but assisted living licensing is left almost entirely to the states. The National Center for Assisted Living, the industry's main policy group, has pointed out for years that assisted living regulation is a state-by-state patchwork, not a single national standard. That means "assisted living" in Florida can look different from "assisted living" in Ohio, both in the services required and in the name of the license itself. Some states call it an assisted living residence. Others call it a residential care facility, a personal care home, or a community-based residential facility. If you're comparing options, assisted living as a category name is really a starting point for research, not a fixed legal term you can look up once and apply everywhere.

What is an assisted living facility, exactly?

An assisted living facility is the physical building and licensed program where assisted living services happen. It's a place licensed by a state agency (usually a health department, aging department, or social services agency) to provide housing plus personal care services to adults, most often seniors, who need support with daily living but not hospital-level medical care. California is a useful example because its law is unusually well documented. California licenses this type of setting as a Residential Care Facility for the Elderly (RCFE) under the RCFE Act, and the state's Community Care Licensing Division within the Department of Social Services runs the licensing program. Other states fold similar homes into an "assisted living" or "personal care home" license instead. The service model is close to identical across states; the label and the specific rule numbers are not. What almost every state definition shares, regardless of the label, is a distinction between housing plus supportive services (assisted living) and housing plus skilled medical care (nursing home). If you search for an assisted living facility definition in your specific state, you'll usually find it buried in the state's administrative code under whatever program name that state uses, not under a plain-English heading.

What is a group home, and how is it different from an assisted living facility?

A group home is a residential setting, usually a single-family style house, where a small number of unrelated adults live together and receive support services, often with awake staff on site. The term is broader than assisted living. Group homes serve seniors, adults with intellectual and developmental disabilities (IDD), people in mental health recovery, and people in substance use recovery, depending on which state program licenses the home. The practical difference usually comes down to size, population, and which state agency issues the license. Assisted living licenses tend to sit with a state's aging or health department and often cover larger buildings with dozens of residents. Group home licenses, especially for IDD or behavioral health populations, tend to sit with a state's developmental disabilities or behavioral health agency and cap resident counts much lower, frequently in the range of four to eight residents, though the exact number is set state by state and you should confirm with your state licensing agency. Some states also license small assisted-living-style homes as adult foster care or adult family homes, which functionally look like group homes but fall under the aging or health department instead. So a six-bed home for seniors and a six-bed home for adults with IDD might sit in completely different regulatory files, with different staffing rules, different inspection cycles, and different forms, even though a visitor would describe both as "a group home."

What does assisted living provide?

Room and mealsYes
Help with bathing/dressingYes
Medication reminders/managementYes, level varies by state
Housekeeping and laundryYes
Social activitiesYes
Skilled nursing (IV, wound care, ventilators)Usually not, or only with a waiver/exception
Rehab therapy (PT/OT/speech)Sometimes on contractNot a core in-house service
24-hour on-site RNRare, state-dependentCommon in nursing homes, not assisted livingA growing number of families also look for assisted living at home options, where personal care aides deliver similar support inside a person's own house instead of a licensed facility. That's a private-duty home care arrangement, not a licensed assisted living facility, and it's regulated under a different set of rules entirely (usually a home care agency license, not a residential facility license).

Assisted living typically provides a private or shared room, meals, housekeeping, laundry, help with activities of daily living (bathing, dressing, toileting, mobility), medication management or reminders, social and recreational activities, and staff available on site around the clock for non-medical supervision. It generally does not provide skilled nursing, IV therapy, ventilator care, or complex wound care, though some states allow licensed nurses to deliver limited skilled tasks under specific rules. | Service | Usually included | Usually NOT included |

What is the difference between assisted living and a nursing home?

Primary regulatorState health, aging, or social services agency (varies)State health department, plus federal Medicare/Medicaid certification
Medical intensityHelp with daily living, medically stable residentsSkilled nursing, rehab, complex medical needs
Staffing ruleSet by state, no uniform federal nursing requirementFederal rule requires licensed nurse coverage 24/7 with set RN hours [1]
Medicaid coverageOptional, usually only through an HCBS waiver, and never for room and boardMandatory Medicaid benefit for eligible adults
Typical stayCan be months to yearsCan be short-term rehab or long-term careThat Medicaid line matters more than most people expect. Nursing facility services are one of the mandatory benefits states must cover under Medicaid, while assisted living is not required at all and is only covered where a state chooses to build an HCBS waiver around it. That single fact drives a lot of the funding gap operators run into when they try to serve Medicaid-eligible residents in an assisted living setting instead of a nursing home.

The core difference is medical intensity. Assisted living is for people who are largely medically stable and need help with daily living. A nursing home (also called a skilled nursing facility) is for people who need ongoing nursing care, rehabilitation after a hospital stay, or complex medical management. Federal law backs this distinction up in a concrete way. Nursing homes that accept Medicare or Medicaid must meet federal staffing and care standards, including licensed nursing coverage 24 hours a day and a registered nurse on duty for a set number of hours daily, under the federal requirements for long-term care facilities [1]. Assisted living facilities are not subject to that same federal nursing rule at all, because they aren't a Medicare or Medicaid "facility type" under federal law in the same way. | Feature | Assisted living | Nursing home |

Does Medicare cover assisted living facilities?

No. Medicare does not pay for room and board or personal care in an assisted living facility. Medicare.gov states plainly that "Medicare doesn't cover long-term care (also called custodial care) if that's the only care you need". Custodial care is exactly what assisted living mostly is: help with bathing, dressing, eating, and moving around. Medicare Part A can cover a short skilled nursing facility stay after a qualifying hospital stay, but that's a nursing home benefit with strict rules (a prior 3-day inpatient hospital stay, a benefit period structure, and coverage that phases down after 20 days), not an assisted living benefit. Some Medicare Advantage plans offer limited supplemental benefits that touch adjacent services, like meal delivery or home safety modifications, but none of that turns into ongoing coverage of an assisted living room and personal care charges. Medicaid is a different story, but only partly. Medicaid can pay for personal care services delivered inside an assisted living facility in many states, usually through a Home and Community-Based Services (HCBS) waiver under section 1915(c) of the Social Security Act, but federal Medicaid rules still don't let states use Medicaid dollars for the room and board portion of the bill. Families end up paying room and board out of pocket, through savings, a long-term care insurance policy, or a VA Aid and Attendance benefit, even in states with a Medicaid waiver covering the care piece.

How much does assisted living cost, and who pays for it?

Nationally, the median cost of assisted living was about $5,350 a month in 2023, compared with roughly $8,669 a month for a semi-private nursing home room and $9,733 a month for a private nursing home room, according to the Genworth Cost of Care Survey. Home health aide services ran close behind assisted living, at a median of about $6,292 a month in the same survey. Those are national medians, and actual pricing swings hard by state, by metro area, and by the level of care a resident needs. A rural county in the Midwest and a coastal metro area can differ by thousands of dollars a month for what looks on paper like the same license category. If you're pricing local competition for a business plan, running senior assisted living facilities near me searches for your target county is a faster reality check than relying on national averages. Payment sources generally break down into private pay (savings, home sale proceeds, family contribution), long-term care insurance, VA Aid and Attendance for eligible veterans and surviving spouses, and Medicaid HCBS waivers that cover the service piece (not room and board) in states that offer one. Every state publishes its own waiver rules, so "does Medicaid pay for assisted living here" only has a real answer once you check your specific state's waiver list.

How do you start a group home?

Starting a group home means working backward from a specific state license, not from a generic business plan. The rough sequence looks like this in most states: pick the population you'll serve (seniors, IDD, mental health, recovery), identify which state agency licenses that population's group homes, confirm the zoning and building code requirements for your property, write your policy and procedure manual, build a staffing and training plan, apply for the license, and pass a pre-licensure inspection before you can accept your first resident. A few things trip up almost every first-time operator. Zoning is one of them, because a residential zone that allows single families doesn't automatically allow a licensed group home, and some states have specific "reasonable accommodation" protections under fair housing law that local zoning boards still misapply. Staffing ratios are another, because states set minimum staff-to-resident ratios and required training hours that you need to build into your budget before you sign a lease, not after. Because every state's application packet, fee schedule, and required forms are different, a lot of operators build their own binder from scratch by pulling forms off a state website one at a time, then redo sections when the agency kicks the application back for something missing. That's the exact gap GroupHomePath's $299 State Group Home Licensing Kit is built to close. It's a state-specific packet of the application steps, policy templates, and staffing plan structure you'll need, organized so you're not guessing which form applies to your population. It doesn't replace your state's own application or guarantee approval; only your state licensing agency can approve a license.

What licenses, staffing, and inspections does a group home or assisted living facility need?

Every state requires, at minimum, a facility license from the agency that oversees your population type, a background check (often state and FBI fingerprint-based) for the operator and staff, a fire and life safety inspection, and an initial health or environmental inspection before you can open. Beyond that baseline, requirements branch out fast, and you should confirm exact numbers with your state licensing agency before you build a budget around them. Staffing rules commonly cover minimum staff-to-resident ratios, required awake overnight staff for certain populations, first aid and CPR certification, medication administration training, and a minimum number of continuing education hours per year for direct care staff. Administrator qualifications also vary; some states require a specific administrator license or a set number of hours of pre-service training before you can run the home day to day. Inspections don't stop once you're licensed. Most states run unannounced or scheduled inspections on an annual or biennial cycle, plus complaint-driven inspections that can happen any time someone files a report. Facilities are commonly checked on medication storage and administration records, staff training files, resident rights postings, emergency preparedness plans, and building maintenance. A facility assisted living inspection checklist from your state's licensing division is usually available as a public document, and it's worth reading before your first survey, not after you fail it.

Which agency regulates assisted living and group homes in my state?

There's no single federal licensing agency for assisted living or group homes, so the honest answer is: it depends on your state and your population. Most states split oversight across a few agencies. A department of health or department of social services typically licenses assisted living and senior residential care. A separate developmental disabilities agency typically licenses IDD group homes. A behavioral health or mental health authority typically licenses recovery and mental health residences. The fastest way to find the right office is to search your state name plus the population you serve plus "licensing division," then confirm you're looking at the primary regulator, more than a Medicaid provider enrollment page (those are related but separate processes). The Administration for Community Living keeps general resources on aging and long-term care programs that can help you find the right state contact if you're starting from zero. Because the agency, the forms, the fee amounts, and the inspection checklist are different in every state, the smartest first move for a new operator is pulling your specific state's current application packet directly from that agency's website rather than relying on a national checklist. If you'd rather start from an organized packet than a blank search, GroupHomePath's licensing kit builder walks through the same state-specific documents by population type, so you can see what your state actually requires before you sign a lease or hire staff.

Frequently asked questions

What is assisted living?

Assisted living is a level of long-term care for adults who need help with daily activities like bathing, dressing, and medication, but not the round-the-clock skilled nursing a hospital or nursing home provides. There's no single federal definition; each state sets its own licensing rules, service requirements, and terminology for this type of care.

What is a group home?

A group home is a residential setting, usually a house, where a small number of unrelated adults live together and receive support services with staff on site. Group homes serve seniors, people with intellectual or developmental disabilities, mental health populations, and people in recovery, and the licensing agency depends on which population the home serves.

What is an assisted living facility?

An assisted living facility is the licensed building and program where a state-approved operator provides housing plus personal care services, such as help with bathing, dressing, and medication management, to adults who don't need hospital-level medical care. States license and name this type of home differently, so the exact legal definition is set state by state, not federally.

What's the difference between assisted living and a nursing home?

Assisted living serves people who are medically stable and need help with daily activities. A nursing home serves people who need ongoing skilled nursing, rehabilitation, or complex medical care, and federal law requires nursing homes to keep licensed nursing staff on duty 24 hours a day. Nursing facility care is also a mandatory Medicaid benefit; assisted living is not.

What does assisted living provide?

Assisted living typically provides a room, meals, housekeeping, laundry, help with bathing and dressing, medication reminders, social activities, and staff available around the clock for non-medical supervision. It generally does not include skilled nursing tasks like IV therapy, ventilator care, or complex wound care, unless a state specifically allows limited exceptions.

Does Medicare cover assisted living facilities?

No. Medicare doesn't cover room and board or custodial care in assisted living. Medicare.gov states that Medicare doesn't cover long-term custodial care if that's the only care a person needs. Medicare Part A can cover a short skilled nursing facility stay after a qualifying hospital stay, but that's a separate, time-limited nursing home benefit, not assisted living coverage.

Does Medicaid pay for assisted living?

Sometimes, and only partly. Many states use a Medicaid Home and Community-Based Services (HCBS) waiver to pay for personal care services delivered inside an assisted living facility, but federal Medicaid rules don't allow Medicaid dollars to cover room and board. Families typically still pay room and board out of pocket even in states with a waiver.

How do I start a group home?

Pick the population you'll serve, identify the state agency that licenses homes for that population, confirm zoning and building code rules for your property, write a policy and procedure manual, build a staffing plan with required training, then apply for a license and pass a pre-licensure inspection. Every state's forms, fees, and timelines differ, so confirm specifics with your state licensing agency.

How many residents can a group home serve?

It depends entirely on the state and the license category. Small group homes for IDD or behavioral health populations often cap out around four to eight residents, while larger assisted living buildings can house dozens. There's no national cap; each state sets its own resident limits by license type, so confirm the exact number with your state licensing agency.

Do assisted living facilities have nurses on staff?

Not always, and it depends on the state. Some states require a licensed nurse to be available or on call, while others only require staff trained in medication administration under supervision. This is a key difference from nursing homes, where federal rules require licensed nursing coverage 24 hours a day and a set number of RN hours daily.

Is a group home the same as an assisted living facility?

Not exactly. Assisted living usually refers to larger, licensed senior residences regulated by a state health or aging agency. Group home is a broader term covering smaller residential settings for seniors, IDD, mental health, or recovery populations, often licensed by a different state agency. The two overlap in practice but sit in different regulatory categories.

How much does assisted living typically cost?

The national median was about $5,350 a month in 2023, according to the Genworth Cost of Care Survey, but actual pricing varies widely by state and metro area. Payment usually comes from private funds, long-term care insurance, VA Aid and Attendance, or, for the service portion only, a state Medicaid HCBS waiver where one exists.

What's the difference between a group home and a nursing home?

A group home provides housing and personal support in a small residential setting, without the skilled medical staffing nursing homes are required to keep. A nursing home is licensed and federally certified to deliver ongoing skilled nursing and rehabilitation care, with mandatory 24-hour licensed nursing coverage under federal law. Residents needing complex medical care generally need a nursing home, not a group home.
