That’s because Cali’s approach is insane. They give you hundreds a month in cash grants (some make $1k a month in SF) and require you to make NO alterations to your lifestyle. I was amazed when living in SF how many of the homeless are not locals. Not even Californians! I myself lived on the streets for a number of years and have dealt with addiction issues. It is absolutely insane how we’ve stopped treating homeless…
On the other hand, $1K a month in SF won't even get you a bed in a shared room. I mean that literally - I just checked apartments.com and there's exactly one listing out of 5,400 right now that's under $1000 and open to non-students.
Check how long those apartments have been listed for, some of them have been listed for a year. If it's an actual competitive price it will get rented immediately.
There are shared housing groups on facebook that will reflect the situation more accurately.
