One solution to the Bay Area housing crisis is cohousing, in which multiple people and families choose to live together. Whether in a single home, or a compound, they share the costs of living and housework.
One example is in Oakland's Temescal neighborhood. The Temescal Creek Cohousing Community is a cluster of two story houses: There's a shared garden, play yard, chicken coop and even a solar hot tub. It was started in 1999 by Karen Hester, who gave Hana Baba the grand tour on a quiet weekday morning.
