Frequently Asked Questions

How many licensed assisted living and shared housing establishments are in Illinois?

The IDPH Assisted Living and Shared Housing Licensed Establishments Listing published on the state open-data portal (data.illinois.gov, retrieved July 2026) contains 495 establishments across 73 counties, with 24,157 licensed units. License issue dates in that export run 2017–2019, so it is a dated snapshot — IDPH licenses and closes establishments year-round, and current status should always be verified through the official IDPH facility lookup.

What is the difference between a Shared Housing Establishment and an Assisted Living Establishment in Illinois?

Both license types sit under the Assisted Living and Shared Housing Act (210 ILCS 9), administered by IDPH. A Shared Housing Establishment is a home for 16 or fewer residents (flat $1,000 license fee) and may use shared bedrooms; an Assisted Living Establishment is apartment-style with private units and kitchenettes ($2,000 + $20 per unit). The IDPH open-data export this directory is built from does not include a license-type column, so each establishment’s current class should be confirmed through the official IDPH facility lookup.

How many Illinois establishments offer Alzheimer’s and memory care?

281 of the 495 establishments in the IDPH export are flagged as providing Alzheimer’s care, with 7,661 Alzheimer’s units listed (same export).

Which Illinois counties have the most assisted living establishments?

In the IDPH export, the five Illinois counties with the most listed establishments are Cook (76), DuPage (38), Lake (35), Kane (26), Will (23). Together the top five hold 198 of the state's 495 listed establishments.

How do I verify an Illinois establishment’s license?

Every establishment in this directory lists the license number from the IDPH export. Verify current license status, license class, and survey history through the official IDPH facility lookup at llcs.dph.illinois.gov — the export behind this directory is a dated snapshot, not a live licensing database.
