I was not aware the numbers were that bleak. Is that total housing units or just rental units?
The US is vast, but of course, let's cram all the technology workers in a tight corner of a bay and densify that to the max.
Grow Out. Of course, SF is a "city", not the kind of city that's part of an urban sprawl like the others. Maybe that's what other cities should start doing. That and quality public transport (not only Google Bus)
Though I was actually surprised it was so high. That's units, not bedrooms, and it's only a city of ~800k people. I guess there's a lot of 1-person households to bring down the average despite all the families and twenty-somethings in 2-4 bedroom units with at least as many inhabitants as bedrooms.
