A cohousing community is a kind of intentional community composed of private homes with full kitchens, supplemented by extensive common facilities. A cohousing community is planned, owned and managed by the residents, groups of people who want more interaction with their neighbours. Common facilities vary but usually include a large kitchen and dining room where residents can take turns cooking for the community. Other facilities may include a laundry, child care facilities, offices, game room, tv room, tool room, and a gym. Through spatial design and shared social and management activities, cohousing facilitates interaction among neighbours, for the social and practical benefits. There are also economic and environmental benefits to sharing resources, space and items.

Because each cohousing community is planned in its context, a key feature of this model is its flexibility to the needs and values of its residents and the characteristics of the site. Cohousing can be urban, suburban or rural. The physical form is typically compact but varies from low-rise apartments to townhouses to clustered detached houses . They tend to keep cars to the periphery which promotes walking through the community and interacting with neighbors as well as increasing safety for children at play within the community. Shared green space is another characteristic, whether for gardening, play, or places to gather.

In addition to "from-scratch" new-built communities (including those physically retrofitting/re-using existing structures), there are also "retrofit" (aka "organic") communities in which neighbors create "intentional neighborhoods" by buying adjacent properties and removing fences. Often, they create common amenities such as Common Houses after the fact, while living there. N Street Cohousing in Davis, CA, is the canonical example of this type; it came together before the term Cohousing was popularized here.

There are over 78 operating communities in the United States with about 100 others in the planning phases. In Canada, there are 7 completed communities, and approximately 15 in the planning/construction process. There are also communities in Australia, the UK and other parts of the world.

Cohousing differs from some types of intentional communities in that the residents do not have a shared economy or have a common set of beliefs or religion. Models of consensus democracy are usually involved in managing cohousing. Individuals do take on leadership roles, such as being responsible for coordinating a garden or facilitating a meeting.

Cohousing communities in the U.S. typically rely on one of three existing legal forms of real estate ownership: individually titled houses with common areas owned by a homeowner association, condominiums or a housing co-operative. Condo ownership is most common because it fits financial institutions' and cities' models for multi-unit owner-occupied housing development. U.S. Banks lend more readily on single-family homes and condominiums than housing cooperatives.

Cohousing differs from standard condominium development and master-planned subdivisions because of the emphasis on consciously fostering social relationships among its residents.

The modern theory of cohousing originated in Denmark in the 1960s among groups of families who were dissatisfied with existing housing and communities that they felt did not meet their needs. It was introduced to North America by two American architects, Kathryn McCamant and Charles Durrett, who visited several cohousing communities and wrote a book about it, . Many cohousing communities exist in Denmark and other countries in northern Europe.
