Ada County has 84 published senior-living communities on Local Senior Advisor, spread across Boise (49), Meridian (22), Eagle (8), Garden City (2), Star (2), and Kuna (1). The U.S. Census Bureau estimated the county's population at 546,141 in 2025, including about 98,764 people age 65 and older, across roughly 1,052 square miles of land.
The listings here come from public records: Idaho Department of Health and Welfare license data for assisted living, CMS data for nursing facilities, and senior-living directories for independent living. That makes this page a starting list of what is licensed and operating in Ada County, rather than a list of advertisers.
Care Levels in Ada County
Assisted Living: 67 communities in Ada County offer assisted living, the most common level of care in Idaho. Most are licensed by the state as residential assisted living facilities, which provide help with daily activities such as bathing, dressing and medications, along with meals and supervision.
Memory Care: 43 listings show memory care, based on secured beds in state license data or a memory-care listing for that community. Families should ask each building how its memory-care area is staffed and secured.
Skilled Nursing: 13 communities provide skilled nursing under a CMS-certified nursing facility license, which covers 24-hour nursing care and, in many buildings, short-term rehabilitation after a hospital stay.
Independent Living: Twelve communities list independent living. Idaho does not license housing that comes without personal care, so these listings come from senior-living directories rather than a state license.
Licensing and Building Size
By license type, Ada County's published listings include 66 residential assisted living facilities, twelve skilled nursing facilities, one campus that holds both an assisted living license and a nursing facility certification, and five directory-listed independent living communities. Idaho's Department of Health and Welfare licenses and inspects residential assisted living facilities under IDAPA 16.03.22, while nursing facilities are also certified and inspected under federal CMS rules. Licensed capacity ranges from 7 to 153 beds, about 4,322 beds in total across the listings with a published bed count. 24 are smaller settings of 16 beds or fewer, which can feel more like a private home, while the larger buildings offer more staff and on-site services.
Hospitals Nearby
Measured in a straight line from the average location of the county's published communities, nearby hospitals include Treasure Valley Hospital (about 1 mile), Saint Lukes Meridian Medical Center (about 3 miles), and Saint Alphonsus Regional Medical Center (about 3 miles), based on OpenStreetMap hospital data. Families should ask each community which hospital its residents usually use and how it arranges doctor visits and transportation.
Paying for Care
Local Senior Advisor does not yet have verified, community-by-community pricing for Idaho. As a statewide reference, the 2024 CareScout Cost of Care Survey (formerly Genworth) put Idaho's median for assisted living at $4,600 a month, below the national median of $5,900, and Idaho nursing home care at $10,068 a month for a semi-private room and $10,707 for a private room. Actual rates depend on the room, the level of care and the building, so it is worth asking each community for its current pricing and what is included. 51 of the listings appear as Idaho Medicaid providers in state or federal data, which matters for families planning for Medicaid now or later.
Getting Help
Local Senior Advisor is a free service to families. A local advisor can help a family in Ada County narrow the list by care needs, budget and location, explain the difference between license types, and set up tours. Visiting at a mealtime, asking how care plans change as needs grow, and getting the monthly rate and what it includes in writing all make the comparison easier.
