This is a tricky problem because housing people isn't free (there is an argument that it saves money on ER bills), housing homeless people in SF is an incredibly inefficient use of money, but at the same time, you don't want cities to be bastions of wealth that outsource their poverty. Action also has to be done at the regional level, or else you'll get a TL situation where homelessness is isolated to one area. Even regional alignment isn't enough, though; the fact that the Bay Area has relatively good homeless services attracts more homeless. Federal housing projects aren't a good answer, either, and least not in the US, because of their history.
