As a Bay Area resident for 2+ decades, SF was very much like this before the Twitter boom brought tech into SF. SOMA, Mission etc were never areas where you could, 'leave your car' and not expect it to be broken into. I read your garage space comment and laughed, in '99 my friends in SF faced the same issues.
SOMA was mostly residential hotels before those were converted into nice apartments and the residents were kicked to the streets. Before the ballpark there was never really any reason for tech workers to go in there.
Mission was quite dangerous to walk around after night before it was deemed hip and thus gentrified.
The period around the 2010 era was the nicest SF has ever been since Mark Twain walked the sidewalks.
