Illinois assisted living: licensing, costs, and rules explained

Last updated 2026-07-24

What is assisted living?

Assisted living is housing that comes bundled with help for daily living tasks: bathing, dressing, medication reminders, meals, housekeeping, and some supervision. It sits between fully independent senior housing and a nursing home. Residents typically have their own apartment or room, plus access to staff around the clock for the tasks they can no longer manage alone. In Illinois, this level of care has a specific legal name. The state licenses "assisted living establishments" and "shared housing establishments" under the Assisted Living and Shared Housing Act, 210 ILCS 9 ^[1]. The law defines an assisted living establishment as a facility that provides or coordinates personal care, 24-hour staff availability to meet scheduled and unscheduled needs, and services like meals, housekeeping, and social/recreational programming, while promoting resident independence and the right to age in place ^[1]. That last phrase, "age in place," matters a lot in Illinois. Unlike some states where a resident gets discharged the moment their needs increase, Illinois assisted living law is built around letting people stay put as they decline, as long as the facility can still meet their needs safely or bring in outside services (like hospice or home health) to fill the gap ^[1].

What is an assisted living facility (and how is it licensed in Illinois)?

An assisted living facility, called an "establishment" in Illinois statute, is a licensed residential building where staff deliver personal care and supportive services to people who need help with daily living but don't need hospital-level medical care. The Illinois Department of Public Health (IDPH) is the licensing authority ^[2]. To operate legally, a facility applies to IDPH, meets building and life-safety requirements, submits a disclosure statement, staffing plan, and resident contract templates, and passes an initial survey before a license is issued. IDPH maintains program information and inspection resources for licensed assisted living and shared housing establishments ^[2]. A few things trip up new operators here. Assisted living in Illinois is licensed differently from a standard board-and-care or sheltered care home. It's also distinct from Supportive Living, a Medicaid-funded variant with its own rules. If you're building out a licensing packet, our state licensing guides hub walks through how state-by-state licensing structures compare, since a plan built for one state rarely transfers cleanly to another.

What is a group home, and how does it differ from assisted living?

A group home is a smaller residential setting, usually a house in a regular neighborhood, where a handful of residents live together with staff support. Group homes serve many different populations: adults with intellectual or developmental disabilities (IDD), people in mental health recovery, or people recovering from substance use. The term is generic and the licensing category depends entirely on who lives there and what services are provided. Assisted living, by contrast, is a specific Illinois license category aimed mainly at older adults and adults with disabilities who need help with personal care. It's typically a larger operation, sometimes 50 to over 100 units, run more like an apartment building with a service package attached. In Illinois, IDD group homes (Community Integrated Living Arrangements or CILAs) are licensed and funded through the Illinois Department of Human Services' Division of Developmental Disabilities, not IDPH's assisted living statute. If you're researching group homes for a specific population rather than senior assisted living, check our group home resources, since the licensing agency, staffing ratios, and inspection cycle are all different from what's described here.

What is assisted living vs nursing home?

Governing law	210 ILCS 9 [1]	Nursing Home Care Act [3]
Licensing agency	IDPH [2]	IDPH [2]
24-hr licensed nursing	Not required	Required
Typical resident	Needs ADL help, some cognitive support	Needs skilled medical/rehab care
Medicare pays room/board?	No	Short-term rehab stays only, under conditions [4]
Medicaid pathway	Supportive Living Program (waiver-adjacent) [5]	Medicaid nursing facility benefit	People often assume a resident who declines will automatically get moved to a nursing home. In Illinois, the assisted living law's "aging in place" philosophy actually pushes the other direction: the facility is expected to try to accommodate increased needs, sometimes by bringing in hospice or outside home health, before discharge is considered [1].

The core difference is medical intensity. Assisted living provides help with activities of daily living (ADLs) and light health monitoring. A nursing home (skilled nursing facility) provides 24-hour licensed nursing care for people with significant medical needs, post-hospital rehab, or conditions requiring constant clinical oversight. Illinois licenses nursing homes under the Nursing Home Care Act, a completely separate statute from the Assisted Living and Shared Housing Act (210 ILCS 9) ^[1][3]. Nursing homes must have licensed nurses on-site around the clock and typically bill Medicaid and Medicare for skilled care episodes. Assisted living establishments are not required to have a registered nurse on-site at all times, and staff there are generally personal care aides, not skilled nursing staff. | Feature | Assisted living (Illinois) | Nursing home (Illinois) |

What does assisted living provide, exactly?

Under Illinois law, an assisted living establishment must provide (directly or by arranging) 24-hour staff availability, personal care services, medication administration or oversight, at least three meals a day, housekeeping, laundry, and social and recreational activities ^[1]. Facilities must also have an emergency call system in each unit and a written service plan for every resident that's reassessed regularly. Beyond the legal minimum, most Illinois assisted living communities also offer transportation to appointments, on-site beauty/barber services, wellness checks, and coordination with outside home health or hospice agencies when a resident's needs exceed what facility staff can provide directly. One thing Illinois assisted living generally does not provide as a core service: skilled nursing care, IV therapy, or ventilator management. Those needs typically require either bringing in a licensed home health agency under a service agreement, or the resident transitioning to a nursing home level of care.

Does Medicare cover assisted living facilities?

No. Medicare does not pay for the room and board or personal care costs of assisted living, full stop. CMS is explicit that Medicare covers medically necessary services, not custodial or long-term residential care ^[4]. A resident living in Illinois assisted living can still use Medicare for doctor visits, hospital stays, and some home health visits ordered by a physician, but the monthly rent-plus-care-package fee itself is private-pay or, in limited cases, covered through a Medicaid pathway. That Medicaid pathway in Illinois is the Supportive Living Program (SLP), a Medicaid-funded assisted living alternative administered jointly by the Illinois Department of Healthcare and Family Services and the Department on Aging ^[5]. Supportive Living facilities look and operate like assisted living but serve income-and-asset-eligible seniors and younger adults with disabilities, with Medicaid paying for the service component while the resident's income covers a set share of room and board. This is a genuinely confusing area for families and new operators alike. Standard Illinois assisted living licensure and Supportive Living certification are related but not identical, and a facility usually has to apply separately for SLP designation on top of its IDPH assisted living or shared housing license ^[5]. For federal program background generally, Medicaid.gov's home and community-based services overview explains how states use waiver-like authorities to fund non-nursing-home long-term care ^[6].

How to start a group home or assisted living business in Illinois

Starting an assisted living or shared housing establishment in Illinois runs through several stages, and skipping ahead on any one of them tends to cause expensive delays. 1. Pick your population and license category first. Senior/disability assisted living goes through IDPH under 210 ILCS 9 ^[1][2]. IDD group homes (CILAs) go through the Division of Developmental Disabilities. Mental health and substance use residential programs may fall under the Illinois Department of Human Services' Division of Substance Use Prevention and Recovery or other categories entirely. Confirm the correct agency and program with your state licensing agency before drafting any paperwork, since the wrong category means starting the application over. 2. Check zoning and building code before signing a lease or purchase agreement. Local zoning boards, not IDPH, decide whether your address can legally hold a residential care use, and building/fire code review for assisted living is more demanding than a standard residential home. Our zoning guidance is worth reading before you commit to a property. 3. Build your operating documents: disclosure statement, resident admission agreement, staffing plan with required coverage ratios, medication management policy, emergency preparedness plan, and financial capacity documentation. IDPH requires proof the applicant has the financial resources to operate the facility for its first year of operation. 4. Submit the license application to IDPH, pay the associated fee (confirm current fee amounts directly with IDPH, since fee schedules are updated periodically), and schedule the pre-licensure survey. 5. Pass the initial inspection, addressing any plan-of-correction items, then receive your license and begin marketing and admissions. This process commonly takes several months from a clean application to an opened facility. That timeline stretches considerably if the property needs construction or major renovation to meet life-safety code. Nobody should assume a fast approval. IDPH's survey and correction process is designed to be thorough, not quick.

How do I start a group home for a specific population (IDD, mental health, recovery)?

If your interest is a group home rather than senior assisted living, the mechanics differ meaningfully even though some steps rhyme with the process above. For adults with intellectual or developmental disabilities, Illinois primarily uses the Community Integrated Living Arrangement (CILA) model, administered through the Illinois Department of Human Services' Division of Developmental Disabilities, with its own provider enrollment, staffing, and Medicaid billing requirements tied to the person-centered service plan. For mental health or substance use recovery residences, licensing can run through different divisions depending on whether the home offers treatment services on-site or is purely a supportive/sober living residence without a clinical license attached. Sober living homes in particular often operate without a state license at all, relying instead on voluntary certification (through organizations like Illinois Alliance of Recovery Residences) rather than IDPH licensure, which is a very different compliance path from assisted living. Because the correct starting agency depends entirely on the population you intend to serve, the single best first move is a direct call to the relevant Illinois state agency to confirm which license or certification category applies, before spending money on a location or staffing plan. Our assisted living facility and facility assisted living guides break down how these categories diverge across states, which is a useful gut check even when Illinois specifics still need direct agency confirmation.

What does Illinois assisted living cost, and who pays?

Pricing is private-pay driven and varies widely by region, unit size, and care level add-ons, so any single statewide average number should be treated skeptically. Get current local pricing from IDPH's facility information and by calling providers directly rather than relying on national survey averages that may not reflect Illinois specifics ^[2]. What's more reliable to state plainly: Medicare does not cover the ongoing cost ^[4]. For residents who qualify financially, the Illinois Supportive Living Program is the main Medicaid-adjacent path to help cover services, with the resident contributing a portion of income toward room and board under program rules set by the Department of Healthcare and Family Services ^[5]. Long-term care insurance, veterans' benefits (like the VA Aid and Attendance benefit), and private funds round out the rest of how Illinois residents typically pay.

What inspections and ongoing compliance should operators expect?

IDPH surveys assisted living and shared housing establishments on a periodic basis and also investigates complaints. Facilities found out of compliance receive a statement of deficiencies and must submit a plan of correction. IDPH's survey and inspection process is worth understanding before you sign a lease near an existing facility or before benchmarking your own compliance program ^[2]. Common deficiency areas nationally, and worth building policy around from day one in Illinois, include medication management errors, incomplete or stale resident service plans, staffing ratio shortfalls during night shifts, and fire/life-safety equipment maintenance lapses. Building your policy manual around these known failure points before your first survey, rather than reacting after a citation, saves real money and stress. This is exactly the kind of buildout where a structured starting point helps. GroupHomePath's $299 licensing kit builder gives operators a state-specific starting framework for the policy manual, staffing plan, and application document set that IDPH and comparable agencies in other states expect to see, so you're not drafting from a blank page.

How does Illinois assisted living compare to shared housing establishments?

Illinois law recognizes two related but distinct license types under the same statute: assisted living establishments and shared housing establishments ^[1]. Shared housing typically involves smaller-scale, more communal living arrangements, sometimes with shared bedrooms or a more modest service package, compared to the apartment-style, private-unit model most people associate with assisted living. Both license types answer to IDPH and both are built around the same philosophy of resident choice, privacy, and aging in place, but the physical building requirements and staffing expectations differ, and a building designed for one category may not qualify for the other without modification.

Frequently asked questions

What is assisted living in simple terms?

Assisted living is housing paired with help for daily tasks like bathing, dressing, medication reminders, and meals, without the round-the-clock skilled nursing care found in a nursing home. In Illinois it's a licensed category (assisted living establishment) under 210 ILCS 9, regulated by the Illinois Department of Public Health.

What is an assisted living facility?

An assisted living facility, or "establishment" in Illinois terms, is a licensed residential building providing personal care, 24-hour staff availability, meals, housekeeping, and activities to residents who need daily living support but not hospital-level medical care. IDPH licenses and inspects these facilities under 210 ILCS 9.

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

Assisted living helps with daily activities and light health monitoring; nursing homes provide 24-hour licensed nursing care for people with serious medical or rehabilitation needs. Illinois licenses them under separate laws: 210 ILCS 9 for assisted living and the Nursing Home Care Act for nursing homes, both through IDPH.

Does Medicare cover assisted living facilities in Illinois?

No. Medicare does not pay for assisted living room, board, or personal care costs anywhere, including Illinois. CMS covers only medically necessary services like doctor visits or qualifying home health, not custodial residential care. Illinois residents typically pay privately or, if eligible, use the Supportive Living Program for help with service costs.

How do I start a group home in Illinois?

First identify the population you'll serve (seniors/disabled adults, IDD, mental health, or recovery), since each uses a different Illinois licensing agency. Confirm zoning, draft your policy manual and staffing plan, submit the application to the correct agency, and pass the pre-licensure inspection before admitting residents.

What is Illinois Supportive Living, and is it the same as assisted living?

Supportive Living is a Medicaid-funded program, administered by Illinois Healthcare and Family Services and the Department on Aging, that funds assisted-living-style care for income-eligible residents. It's related to but separate from standard IDPH assisted living licensure; facilities typically need both an assisted living license and separate SLP certification.

How long does it take to get an assisted living license in Illinois?

There's no fixed guaranteed timeline. A clean application with a code-compliant building can move in a few months; a property needing construction or major life-safety upgrades can take much longer. Confirm current processing expectations directly with IDPH rather than assuming a specific number of weeks.

What's the difference between a group home and an assisted living facility?

A group home is typically a small residential house serving IDD, mental health, or recovery populations, licensed through agencies like the Division of Developmental Disabilities. Assisted living is a larger, IDPH-licensed category mainly for older adults and adults with disabilities needing personal care support.

Can an Illinois assisted living resident stay if their health declines?

Often, yes. Illinois assisted living law is built around letting residents age in place, meaning facilities are expected to try to accommodate increased needs, sometimes with outside hospice or home health help, before requiring a resident to move to a nursing home.

Who regulates assisted living facilities in Illinois?

The Illinois Department of Public Health (IDPH) licenses and inspects assisted living and shared housing establishments under the Assisted Living and Shared Housing Act, 210 ILCS 9. IDPH also oversees inspection reports and facility information for licensed establishments.

Is a shared housing establishment the same as assisted living in Illinois?

They're related but distinct license categories under the same Illinois statute (210 ILCS 9). Shared housing tends to involve smaller-scale or more communal living arrangements, while assisted living is typically apartment-style with private units, and each has separate building and staffing requirements.

What does assisted living not cover that a nursing home does?

Assisted living does not provide 24-hour licensed nursing care, IV therapy, ventilator management, or intensive rehabilitation services. Residents needing those levels of care typically require a licensed nursing home or must bring in a separate licensed home health agency under a service agreement.
