I mean, I don't know how to tell you guys, but from the perspective of an east coaster, the entire peninsula looks like this. It feels like some kind of parallel universe where nothing makes sense. The Peninsula is bland and awful. Plenty of affluent folks that just like to fuck with people (a.k.a. Atherton and the NIMBY's asinine fight against electrifying Caltrain). Plenty of folks (a.k.a. Brisbane) that like to pretend they're rich and only want to develop commercial property and leave the housing to SF.
But... the Bay Area is incredibly provincial. San Mateo county (most of the peninsula) is not San Francisco.
Like I hear about a housing crisis in SF but I go there and there are supermarkets surrounded by parking lots in the middle of the city. There are literal big-box stores like you'd see in the suburbs adjacent to the central business district, like that Petco Safeway block near Mission Bay.
Part if it is that there are chain retail bans in many neighborhoods, but the other part is where are you going to put the big stores? Cities in San Mateo county fight tooth and nail over the big box stores (see the Target in Colma directly across the highway from the Target in Daly City). Retail = tax revenue. Middle class jobs = less tax revenue. San Francisco can afford to levy payroll taxes and whatnot, but other cities don't have that prestige.
You head to the beach and you go through mile after mile of outer sunset with crappy little 2 story houses and residential streets dominated by garage doors which is like the most people-unfriendly building style known to man.
You're starting to see more multi-unit housing in the Sunset, but again SF is not the peninsula. As bad as things are in San Francisco, things are far worse to the south. The garages are often two car sized and likely converted into illegal residential units.
Like do people know that every little private one-car garage has no benefit on a larger scale? The garage holds one car, and the curb cut prevents parking on the street in front, for a net gain of zero parking spaces.
Curb cuts make walking in SF worse than it has to be, but try walking in the suburbs where there are sometimes no sidewalks, higher speed limits, and wider roads to cross on foot.
