My guess is nope, since they are leveraged heavily to be able to get in to that home.

Great. So we can have even more traffic, and even less spaces to park. I don't think that adding more housing is going to make SF a better place.

Are cars even necessary in SF?

The SF housing crisis wouldn't be exist or if it did exist not in this severity if they'd built more housing a decade or more ago.
