On Mission street in my neighborhood alone there are at lease 3 large lots with derelict buildings on them and they've been that way for years. There are quite a few other smaller parcels on Mission and smaller streets.
If we want to take housing seriously, let's start with a law that says "If the building is abandoned for 5 years, you lose it, it becomes housing."
Unless SF eliminates its insane height restrictions, the very few buildings that would be repurposed in this fashion would immediately become $4000 apartments.
It's a few drops in the bucket, yes -- but if we can't even bring ourselves to turn derelict buildings into housing, it's hard to claim that we're serious about solving the problem.
