This is true for most places, but expensive build locations like the Bay Area, where custom homes are $400-600+ psf allow for competitive modular in the 2xx price range.
It's fun to watch Silicon Valley rediscover everything that the rest of America has already known about for decades.
The only way $200/'' modular competes anywhere connected to the US highway network is if their customers don't know anything about the market they're buying into. Or if they have legal protection from competition.
The only reason I can think of to explain why SV isn't already absolutely infested with offsite-manufactured homes is that all the municipalities are pulling out every type of local government shenanigan to halt their importation. Perhaps the homes shown on the OP site somehow exploit a loophole that otherwise keep the bigger manufacturers out. That stuff happens even in vanilla American suburbia, to keep the trailer-park atmosphere from invading the town, so I can easily imagine the comfortable California NIMBYs pulling their sharpest knives on anyone threatening property values.
