Boulder County's senior living network reaches beyond the city that gives the county its name. Longmont and Lafayette hold the larger share of the county's communities, with Boulder rounding out a mix of small residential homes, larger campuses, and one continuing-care community covering every level of care.
About 17 percent of Boulder County's residents are 65 or older in 2026, enough to support senior living in more than one town rather than a single hub, so families are not forced to choose between staying near Boulder and finding an open community.
Where Care Concentrates in Boulder County
Assisted living carries most of Boulder County's senior living; where the other three levels show up varies by town.
- Independent Living: One setting, inside a small Longmont continuing-care community that also offers assisted living and skilled nursing. Families wanting a standalone building usually look toward greater Denver.
- Assisted Living: The most common level, spread across Longmont, Lafayette, and Boulder from small residential homes to larger campuses, letting families choose scale without leaving the county.
- Memory Care: Available at several Longmont and Lafayette buildings, usually built into an assisted-living community rather than a separate wing. Ask each building how support works day to day.
- Skilled Nursing: Limited to one Longmont and one Lafayette building, both tied to rehabilitation services. Longer stays are typically arranged through a hospital discharge team.
Many of the county's buildings mix care levels under one roof, so a resident can often add support as needs change without a move.
Boulder County's Hospital Network
Three hospital systems carry Boulder County's clinical load, one in each of its larger cities. Boulder Community Health's Foothills Hospital in Boulder runs a Level II trauma center with a 25-bed emergency department.
Intermountain Health's Good Samaritan Hospital in Lafayette is a 234-bed Level II trauma center handling more than 35,000 emergency visits a year, serving Lafayette, Louisville, and Erie. UCHealth's Longs Peak Hospital in Longmont is an 89-bed acute-care hospital with a Level III trauma center and a falls-prevention program built for older adults.
What Drives Pricing in Boulder County
Boulder County's cost of care depends more on building type than on which city it sits in. A small home-style setting charges one way, a larger campus with dining service and round-the-clock staff charges another, and the county's one continuing-care campus in Longmont sets its own rate structure across its combined levels of care.
Level of care adds to cost as much as building size, since memory care support typically costs more than light assistance. Rates shift by building through 2026.
Why Families Stay in Boulder County
Boulder County draws retirees who spent careers at the University of Colorado Boulder, in tech, or in federal research labs and want to stay near the trails and foothills they built a life around. Longmont and Lafayette add a quieter draw for adult children working in Denver or Broomfield who want a parent within a short drive.
The St. Vrain Greenway, Lafayette's Waneka Lake Park, and Boulder's open-space trails give residents an easy walk most afternoons, and grandchildren in the Boulder Valley and St. Vrain Valley schools keep generations close.
What a Local Advisor Brings to Boulder County
Finding the right fit in Boulder County usually means weighing a Longmont campus against a Lafayette home against Boulder's smaller options, and a Local Senior Advisor familiar with the county already knows which buildings have an opening, which accept Health First Colorado through the Elderly, Blind and Disabled waiver, and which pair assisted living with memory care under one roof.
