In SF we absolutely haven't (especially if you add in the peninsula), but the planning rules are ridiculously restrictive, especially outside the SoMa "core".

In SF we absolutely haven't (especially if you add in the peninsula), but the planning rules are ridiculously restrictive, especially outside the SoMa "core". We're probably who this is aimed at. The Bay area has some of the most bizarre real estate realities - the most expensive commercial real estate in the US, along Sand Hill Road - is mostly ugly 2-3 story suburban office buildings. It costs more than Park Avenue. And residential is worse, especially in the peninsula - rambling, ugly, 70s built single family houses for millions of dollars. No hope of ever building a 5 story apartment building, let alone the high rises the local economy would support. There is a very strong trend towards protecting everything as it was in the 70s, even as ridiculous and exclusionary as that is in practice.
