Jefferson County has three published senior-living communities on Local Senior Advisor, all in Rigby. The U.S. Census Bureau estimated the county's population at 35,297 in 2025, including about 4,857 people age 65 and older, across roughly 1,094 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 Jefferson County, rather than a list of advertisers.
Care Levels in Jefferson County
Assisted Living: Three communities in Jefferson 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: Three 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.
Licensing and Building Size
By license type, Jefferson County's published listings include three residential assisted living facilities. 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 16 to 32 beds, about 72 beds in total across the listings with a published bed count. One is a smaller setting of 16 beds or fewer, which can feel more like a private home, while the rest are mid-sized buildings.
Hospitals Nearby
Measured in a straight line from the average location of the county's published communities, nearby hospitals include Madison Memorial Hospital (about 12 miles), Mountain View Hospital & Idaho Falls Community Hospital (about 15 miles), and Eastern Idaho Regional Medical Center (EIRMC) (about 15 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. 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. Three 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 Jefferson 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.
