We have previously discussed how widespread loneliness is among older adults in the United States. A 2018 AARP Foundation study found that 35 percent of Americans over age 45 report feeling lonely — more than one in three. The rate is even higher among lower-income groups (household income under $25,000), where roughly half report loneliness.
Loneliness can have serious health consequences for seniors. Research links loneliness to higher risks of dementia, depression, elevated blood pressure and earlier mortality. In 2017 testimony before Congress, Julianne Holt-Lunstad, Ph.D., noted that loneliness can be as harmful to health as smoking, excessive alcohol use or serious illness.
One striking finding from the AARP study is how much neighborly contact matters. Among adults 45 and older who have spoken with their neighbors, 33 percent say they are lonely. But among those who have never spoken to their neighbors, 61 percent report loneliness. In other words, regular contact with neighbors can reduce loneliness by nearly half.
That insight helps explain the growing interest in cohousing as a model of senior living.

Cohousing communities for senior living
Cohousing blends private residences with shared indoor and outdoor spaces designed to encourage daily interaction and mutual support. The goal is to enable seniors to live independently while benefitting from an intentional, neighborly community.
Residents typically own or rent individual homes or condos but share communal areas such as gardens, patios and a community kitchen where people can cook, dine and socialize together. These shared spaces are designed to make casual interactions and cooperative activities easy and natural.
Advocacy groups for senior cohousing identify several core principles that define this model:
- Participatory design: Future residents contribute to planning and design so the community reflects their needs and preferences.
- Neighborhood layout: Homes and shared spaces are clustered to promote walkability and spontaneous neighbor interactions.
- Common facilities: Shared indoor and outdoor areas are intended for everyday use and form the heart of community life.
- Resident management: Residents manage operations, from organizing meals to coordinating maintenance tasks.
- Non-hierarchical decision-making: Communities rely on inclusive, consensus-based processes rather than formal leadership hierarchies.
- No shared community economy: Members typically contribute time and effort rather than pay one another for community tasks; these contributions are part of shared responsibility.

Similarities to other senior living communities
Cohousing shares features with other senior living options, such as continuing care retirement communities (CCRCs or life plan communities). Both models emphasize social engagement and community supports that contribute to mental and physical well-being. Shared meals, group activities and communal spaces help residents form friendships and support networks.
Both cohousing and CCRCs can also extend independent living by offering age-friendly design elements: single-level homes, accessible paths and thoughtfully designed common areas that reduce everyday barriers.

Cohousing community distinctions
Key differences between cohousing and CCRCs include governance, responsibilities and cost structure. Cohousing is typically self-managed: residents organize and perform many community tasks and share responsibility for upkeep. Prospective residents should understand the expectations for participation and the terms of any homeowners association or shared agreements.
CCRCs, by contrast, are managed by paid staff and often overseen by a board. Staff handle daily operations, maintenance, meal services and activity programming, while a resident council may offer input. Residents pay monthly fees that usually cover housing, services, meals and facility maintenance; some CCRCs also require an entrance fee. In cohousing, residents typically own their homes and pay HOA fees that cover shared-space expenses, with occasional collective decisions to hire contractors for major projects.

A key difference
The most significant distinction is the availability of on-site medical and care services. CCRCs provide a continuum of care on campus, from independent living support to assisted living services and skilled nursing when needed. Cohousing does not generally provide on-site medical or long-term care services as part of the community model, although residents can arrange private in-home care if needed.

An innovative concept to confront loneliness
The COVID-19 pandemic highlighted how common and harmful loneliness can be, but the issue predates the pandemic. As more people enter retirement age, addressing the loneliness epidemic becomes increasingly urgent. Cohousing is one promising, cost-effective model that fosters daily social connection and mutual support while helping seniors maintain independence longer.
