What is elder or senior cohousing?

Cohousing came to the U.S. 15 years ago from Denmark, where intergenerational communities gave birth to a successful, age-specific cohousing model for active elders. The first elder-only cohousing neighborhoods for active adults, 55 and above, are just now emerging in the U.S. Design features include easy access for all levels of physical ability and also may include optional studio residences in the common house to provide living quarters for home health aides whose services may be shared by several residents.
