HOPE VI supports demolishing large, dilapidated public housing and replacing it with smaller-scale, more appealing properties. What makes this feasible (mixed financing; private-sector entities; and mixed-income, mixed-tenure complexes) also creates conditions that challenge and can undermine long-term sustainability. Sustainability has not yet been assessed and whether it should or can be assessed has been questioned. With input from housing practitioners and insight from a trial exploration of two HOPE VI redevelopments, this report demonstrates the need for, and feasibility of, conducting an assessment that can assist both private owners and public agencies in sustaining this valuable resource.
