1. Upzone SOMA district to 12 stories.
2. Remove requirement that buildings over 50yrs old in SOMA need to pass the historic building committee.
SF has a complicated review process that basically lets neighbors hold up permit approval indefinitely with appeals. Whether good or bad, it's there. Shadow laws are also in place and would need to be changed.
Changing a low to mid density neighborhood into a high density 12 story building neighborhood means a lot more than just removing height limits. Sufficient parks and retail/commercial space need to exist to ensure good quality of life, no one wants to live in a neighborhood full of condos & apartments and little else.
Likewise, there needs to be sufficient transit, SF Muni is already bursting at the seams, add a high density neighborhood without adding transit, and no one will be able to get out of the neighborhood.
Building high density housing is important but it's a lot harder than just removing a height limit.
But aren't these suggestions a bit like in the late 90s when you would just add more beefy servers to a really slow web site? Even if these ideas would add the required 100,000 units to the market, how do you deal with the politics of making these two changes happen?
The housing shortage / underbuilding crisis is actually a wicked problem. Before throwing solutions onto the wall, we should understand its beastly nature better.
