What decides whether supportive housing helps or hurts a block?

Management quality decides most of the outcome for supportive housing on a given block, since a well-staffed, well-run building with active on-site services tends to blend into a neighborhood, while an under-resourced one with inadequate supervision can create real problems for neighbors. Building design, staffing ratios, and whether the operator has a track record elsewhere all factor into that outcome more than the concept of supportive housing itself. Scale relative to the surrounding block also matters. Joel Boss can speak to how a specific proposal compares to others he has seen.
