The short answer

  • License: assisted living establishment or shared housing establishment, licensed by the Illinois Department of Public Health under the Assisted Living and Shared Housing Act (210 ILCS 9) and 77 Ill. Adm. Code 295.1
  • Assessment: a comprehensive physical, cognitive and psychosocial assessment before admission. The rule says the physician's assessment can be done no more than 120 days before move-in.2
  • Preferences: the Act says the service plan is based on the assessment and "the resident's interests and preferences, dislikes, and any known triggers."1
  • Reassessment: at least annually and on a significant change. The service plan is also reviewed when the resident's preferences change.3
  • Dementia programs: the service plan must offer familiar activities that tap memories and let residents keep their accustomed social roles.4

Who these rules cover

Illinois licenses two settings under the Assisted Living and Shared Housing Act: assisted living establishments and shared housing establishments (the smaller setting). Both are licensed by the Illinois Department of Public Health (IDPH), and the detailed rules sit in 77 Ill. Adm. Code Part 295, the Assisted Living and Shared Housing Establishment Code.

The Act describes assisted living as "services consistent with a social model that is based on the premise that the resident's unit in assisted living and shared housing is his or her own home."6 That framing matters for everything below. The rules lean on the resident's choices, not only on a care checklist.

Illinois also runs a Medicaid Supportive Living Program. The Act excludes supportive living facilities from its definition of an establishment, so they follow separate rules that this page does not cover.6

The assessment: what and when

Section 15 of the Act requires a comprehensive assessment before admission. It is completed by a physician, a physician assistant, or an advanced practice registered nurse, and it evaluates the prospective resident's "physical, cognitive, and psychosocial condition."1 The rule adds a timing window:

No more than 120 days prior to admission of a resident to any establishment, a comprehensive assessment that includes an evaluation of the prospective resident's physical, cognitive, and psychosocial condition shall be completed by a physician.77 Ill. Adm. Code 295.4000(a)

Two practical points. First, the rule text still says "physician," while the Act as amended also lists physician assistants and advanced practice registered nurses. When the two differ, check with IDPH on how they apply the current statute. Second, the rule lets you use your own evaluation tool on top of the clinical assessment. Documentation "may be in any form that is accurate, that addresses the resident's condition, and that incorporates the physician's assessment."2 That is where most communities capture the personal material: routines, likes, dislikes and history.

Reassessment happens at least annually and "upon identification of a significant change in the resident's condition." The Act names a new diagnosis of Alzheimer's disease or a related dementia as one example of a significant change.1

The service plan

This is where Illinois stands out. The Act spells out what the plan rests on:

Based on the assessment, the resident's interests and preferences, dislikes, and any known triggers for behavior that endangers the resident or others, a written service plan shall be developed and mutually agreed upon by the provider, the resident, and the resident's representative, if any.210 ILCS 9/15

So the plan is not only an ADL grid. It has to reflect what the person likes, what they do not, and what sets them off. The rule adds who writes it and what it covers:

RequirementWhat the text saysSource
Who develops the planThe resident (or representative or anyone the resident asks for), the manager or designee, and an RN if the resident receives nursing services or medication administration or cannot direct self-care295.4010(b)
SignaturesSigned and dated by everyone involved in developing it295.4010(c)
Resident choiceThe establishment "shall respect and accept the resident's choices regarding the service plan"295.4010(a)
What it addressesLevel of service (ADL help, diets if offered, special accommodations), health-related services, responsible staff, negotiated risk, medication support295.4010(g)
ReviewAnnually, or more often as condition, preferences, or service needs change; immediately after a significant change295.4010(d), (e)
The service plan, which shall be reviewed annually, or more often as the resident's condition, preferences, or service needs change, shall serve as a basis for the service delivery contract between the provider and the resident77 Ill. Adm. Code 295.4010(d)

Note the word "preferences" in the review trigger. A change in what the resident wants is, on its own, a reason to revisit the plan.3

Activities and social programming

For general assisted living, Illinois does not list an activities program among the mandatory services. The mandatory list is meals, housekeeping, laundry, security, an emergency response system, and help with activities of daily living.7 The Act does require that "sufficient common space shall exist to permit individual and group activities."6

In plain terms: outside a dementia program, Illinois does not set a required activity calendar. What it does require is that the service plan reflect the resident's interests and preferences. Most communities meet both goals by linking the activity calendar to what they learned at move-in.

Alzheimer's and dementia programs

An establishment that offers a special program or unit for people with Alzheimer's disease and related disorders must meet Section 150 of the Act and 77 Ill. Adm. Code 295.4060. The statute requires the program to "provide cognitive stimulation and activities to maximize functioning."5 The rule goes further and describes what that should look like in the service plan:

Provide, in the service plan, appropriate cognitive stimulation and activities to maximize functioning, which include a structure and rhythm that are comfortable and predictable; offer an appropriate balance of rest and activity and private and social time; allow residents to express their accustomed social roles, whatever they may be; offer residents access to familiar activities that they enjoyed doing and that tap memories and retained abilities; and provide the flexibility to accommodate variations in the resident's mood, energy level, and inclination77 Ill. Adm. Code 295.4060(h)(5)

That sentence does not say "life history," but it cannot be met without one. You cannot offer "familiar activities that they enjoyed doing" or honor "accustomed social roles" without knowing who the person was: the retired teacher who still wants to help others, the farmer who is up at five, the woman who hosted every holiday.

Other dementia-program duties include a pre-admission assessment with a validated dementia-specific tool, a designated resident representative, coordinated communication with relatives and others named in the service plan, and at least 1.4 hours of services per resident per day, which the rule defines to include activities-based programming.4 Programs must also make disclosures under the Alzheimer's Disease and Related Dementias Special Care Disclosure Act.5

What surveyors tend to look for

Based only on what the text asks you to document, a surveyor reviewing a file can reasonably expect to find:

How to gather preferences and life history well

The Act asks for interests, preferences and dislikes. The dementia rule asks for familiar activities and social roles. A short, human process covers both.

How Porchlight can help

Porchlight is a simple way to collect the interests, preferences and life-story material that Illinois asks the service plan to rest on, in the resident's own words. A resident taps one large button on a tablet, a life question is read aloud and shown in large type, they talk, and the answer is recorded and transcribed. There are 800+ human-written questions organized by life chapter, any of which can be skipped, and nothing is scored. Staff can record profile facts, including topics to avoid. Family get a private page to listen, leave voice replies and add their own questions and photos. Staff get a "Know Your Resident" briefing with conversation starters, story highlights, a printable life-story biography and a weekly Monday email digest. The assessment, the service plan and compliance remain your community's responsibility.

Frequently asked questions

Does Illinois require assisted living to document a resident's preferences?

Yes. Section 15 of the Assisted Living and Shared Housing Act says the written service plan is developed based on the assessment and on the resident's interests and preferences, dislikes, and any known triggers for behavior that endangers the resident or others. The plan is also reviewed when the resident's preferences change.

When must the Illinois assessment be done?

Before admission. The Act requires a comprehensive assessment of the prospective resident's physical, cognitive, and psychosocial condition before admission, and the rule at 77 Ill. Adm. Code 295.4000 says the physician's assessment may be done no more than 120 days before admission and must reflect the resident's current condition at the time of admission.

How often is the service plan reviewed in Illinois?

At least annually, more often as the resident's condition, preferences, or service needs change, and immediately after a significant change in physical, cognitive, or functional condition.

Does Illinois require a life history for residents with dementia?

The rules do not use the words life history or social history. But the dementia program rule requires the service plan to offer familiar activities the resident enjoyed that tap memories and retained abilities, and to let residents express their accustomed social roles. You cannot do that well without knowing the person's past.

Do the federal nursing home rules apply to Illinois assisted living?

No. The federal nursing home requirements in 42 CFR Part 483 apply to certified nursing facilities. Illinois assisted living and shared housing establishments are licensed by the Illinois Department of Public Health under the state Act and 77 Ill. Adm. Code 295.
