IDPH licenses Deer Park Village Senior Living for 84 assisted living units: 60 regular assisted living units, 24 Alzheimer's/dementia special care units. IDPH's total of 180 also counts 96 units outside those categories — typically independent living apartments on the same campus — which this license doesn't break out. About 29% of the licensed units are dedicated to Alzheimer's care, so dementia support is a meaningful part of its program.
Illinois licenses assisted living by living unit rather than by bed. An Alzheimer unit belongs to a special care program for people with Alzheimer's disease or a related dementia, which the Assisted Living and Shared Housing Act (210 ILCS 9) and 77 Ill. Adm. Code 295 hold to added staffing, training and environment requirements.
Deer Park Village Senior Living is operated by Deer Park IL Senior Living LeaseCo LLC, and IDPH records show a change of ownership at this address: the earlier licensed entity (Deer Park Village Senior Living) is now marked “Inactive – CHOW.” The current licensee's first license period in the IDPH system began July 24, 2026.
An ownership change doesn't by itself mean care changed, but ask what stayed the same — administrator, nursing lead, pricing and residency agreement terms — and what the new operator changed.
None are posted. As of October 23, 2026, the IDPH public lookup lists no survey reports, violations or enforcement actions for Deer Park Village Senior Living. That reflects what IDPH publishes online, not a guarantee that no survey has taken place.
Ask the administrator for the most recent IDPH survey and any plan of correction — establishments receive them and can share them.
