While we'd expect most neighborhoods with families would oppose such a housing project, this case has mitigating factors.
Sponsors,    which will be supervising these residents,  is an excellent program which has helped thousands of ex-offenders get their lives back on track.  If they are mainly going to house those over 55 who have completed a lengthy treatment program. there should be little recidivism.
Back when I was active  in the Westside Neighborhood we had several organized group homes, probably more than any other neighborhood ,which displeased some of the residents..
There was even a group home for mentally ill former criminals with serious offenses, which most nearby residents didn't even know existed or they'd probably have opposed it.  Of all these institutions Sponsors was the best.  
The reality is that most neighborhoods will say "NIMBY", which is why the idea of "community oriented" programs replacing large institutions is the ideal, but difficult to carry out.
