They can’t fix anything in SF because then it would ruin the aesthetic of ticky tacky faded pastel colored wall-to-wall vinyl sided two story houses with those single-car-garages-with-uselessly-steep-driveway-angles. At least the people who bought those for $60k back in the 60s get to pay about 1/20th of what the next owner would in property taxes so they can stay to witness the city crumble around them. Don’t want to mess up the feel of the neighborhood, you know.
