Mission is the densest after ~downtown. Main drags and outskirts are switching to 4+1 (progress!) but most of it remains 2-3. So even there, still a lot possible well before skyscrapers. Though rent control is double edged: needed to keep folks housed, but also prevents rebuilding.

Interestingly, mission bay ucsf campus made a bunch of big buildings, so would seem consistent to add corresponding housing. Though expensive/dangerous..

Yeah so Mission and Downtown both have densities greater than the mean Paris population density. Certainly improving density in the outer boroughs is probably a smarter decision but those areas also aren’t where SF builds the larger buildings and likely where the NYMBism will be strongest.
