If we just slightly upzoned the whole western half of the city, and added public transit to go with it (even better if streets were narrowed a bit and street parking reduced), San Francisco could fit a whole heck of a lot more people without ever needing new buildings taller than 4 or 5 stories. San Francisco zoning through huge swaths of the city is restricted to single-family houses and scattered duplexes, with only a few mixed-use areas. It’s supposed to be a booming city, but more than half of it is zoned to be a sleepy beach town. (And a lot of the Bay Area is even worse.) Here’s the SF zoning map. All the pale yellow part is very low density; If it were up to me we would change half or more of that pale yellow area to some mix of darker yellow, orange, and purple. http://default.sfplanning.org/zoning/zoning_map.pdf http://default.sfplanning.org/zoning/zoning_map.pdf
