SF Housing Accelerator

What SF Housing Accelerator does

San Francisco Housing Accelerator Fund (HAF) is a 501c3 nonprofit organization and certified U.S. Department of the Treasury Community Development Financial Institution (CDFI), founded in 2017 and headquartered at 564 Market Street, San Francisco. HAF was incubated at San Francisco City Hall under Mayor Ed Lee as a public-private partnership and today operates across seven Bay Area counties (San Francisco, San Mateo, Santa Clara, Alameda, Santa Cruz, Sonoma, and Oakland). The organization provides flexible, fast-deploying financing products to nonprofit affordable housing developers, including predevelopment loans, land acquisition financing, anti-displacement bridge loans for small multifamily buildings (Small Sites Program), acquisition and rehabilitation of Single Room Occupancy (SRO) and residential hotels, permanent supportive housing financing, underutilized land acquisition loans, and construction and construction-to-permanent loans.

HAF's revenue model combines transaction-based interest and fees on its loan portfolio with philanthropic grants, program-related investments (PRIs), and below-market capital from foundations, banks, and corporate partners. Capital is deployed through three branded fund vehicles: the Bay Area Housing Innovation Fund ($100M, founded 2024, targeting 40% cost-and-time savings), the Industrialized Construction Catalyst Fund ($10M revolving pool launched February 2025 for modular construction financing), the Home for Good Fund ($26M raised of a $50M goal, administered in partnership with the San Francisco Foundation), and the Alliance Housing Fund ($6.8M from Central California Alliance for Health). Major investors include Apple, JPMorgan Chase ($22M, January 2020), First Republic Bank ($100M commitment, February 2020), Sobrato Philanthropies, Chan Zuckerberg Initiative, Destination: Home, Valhalla Foundation, Wells Fargo, Bank of America, Citi Community Development, Silicon Valley Community Foundation, UCSF, and CommonSpirit Health.

The organization has financed more than 3,555 affordable homes preserving and producing housing for over 6,500 residents, including 875+ units of permanent supportive housing for individuals experiencing homelessness. Leadership is led by founding CEO Rebecca Foster (ex-Goldman Sachs, ex-Mayor's Office Director of Social Impact Investment), CFO Tamar Dorfman, Chief Lending Officer Kate Hartley (former MOHCD director who oversaw 10,000 preserved/new units), and Chief Investment Officer Jan Lindenthal-Cox (ex-MidPen Housing). HAF operates with approximately 17 employees and distributes financing through direct, relationship-based lending rather than traditional marketing channels.
