By "gigantic" I'm sure you really mean is the 1200-1800sqft tract ranches from the 1940s-60s that consume the majority of the developed suburban land, right, because there are almost 0 gigantic houses in the region compared to literally every other major metro in the country. And that's one of the problems: too many people stretched their budgets to buy crappy $1m houses, they can't really afford to do it again, and prop 13 (plus impending rising mortgage rates) actively disincentivize anyone from selling after they manage to get into this market, no matter what their house is like.
