How many co-housing or co-op projects designed for older adults exist, and how many are planned?

There are currently four co-housing communities designed for older adults in the country (with many more in Northern Europe, where they originated). In this country, two of these, Wolf Creek and Glacier Circle, are located in California and an additional five communities are now under development, including Phoenix Commons. There are many more senior cooperatives in the Midwest and East Coast, where co-ops are common forms of ownership. There are many co-housing and cooperative communities throughout the United States that have no age restrictions – they are often called multi-generational communities. Age-restricted communities are new, but are quickly becoming much more popular. Some of the seniors who live in senior-only co-housing and co-ops moved there from multi-generational communities.
