LaQuerencia is a 28-unit cohousing project under development in Fresno, Calif. Many members are Unitarians.

The Elder Cohousing Network in Davis, Calif., an eight-household community, opened in January 2006 as the first elder cohousing development in the country. Members range in age from 76 to 92; the community grew out of a Unitarian Universalist congregation in Davis.

Mid-Atlantic Cohousing is a regional clearinghouse for cohousing communities in Washington, D.C., and nearby states. Kevin Oliveau, founder of Catoctin Creek Village in Taylorstown, Va., says a common value for cohousing groups is community. While most cohousing groups are not denominational, many Quakers and Unitarians are drawn to the arrangement.
