HOPE SF aims to shift public housing models away from the failed paradigm of large, isolated islands of poverty and deteriorating housing toward a new vision of high-quality, mixed-income housing developments with strong social service support for families. HOPE SF’s innovative model for revitalizing public housing draws on more than 15 years of lessons learned from Hope VI, as well as research by the Urban Institute, Brookings Institute, Center on Budget and Policy Priorities and Harlem Children’s Zone.
