From what I’ve seen in San Francisco, the biggest decreases in rents have been in the newer upscale construction in SOMA. There’s nothing to do in SOMA other than walking to your tech office job and most of the restaurants around there are specifically for business lunch so many of them aren’t open now with the offices are be closed.

In other parts of San Francisco prices have dropped but not nearly as much as in SOMA.
