I cannot speak to whether existing building code stair/elevator requirements do or do not make (new) small footprint residential towers impossible, but seismic issues are not obviously a factor. SF's existing tall/thin residential towers have not suffered any notable earthquake damage over the decades. Because developers can make a lot of money with taller buildings, and because the views are great, I suspect there would be a lot more of these if it weren't for modern-day NIMBYism:
