Our purpose is to greatly increase the supply of multifamily rental housing for all income levels struggling to afford housing in California.  Most of our projects do not receive any public funding because there is not enough such funding to address California’s housing crisis.  One of our core competencies is providing a pathway for existing local organizations to develop mission-driven housing on land they own.  Our current projects range from 6 units to 118 units and from permanent supportive housing to workforce housing to co-living units.

We are currently advancing housing development projects and partnerships in the Monterey and San Francisco Bay Areas.
