The problem is that most US houses are quite poor for multi-generational living, as they generally revolve around a single common area with an open design. The traditional multi-family house has been gobbled up by the rental market, and now even the in-law apartment has been gobbled up by short term rentals. It's possible to build new in-law apartments with conditional approval from the city that it will only be used by related family, but that just dovetails into the problem of needing to build. There's also the general problem that the costs of system-legible senior care have shot up to ridiculous levels. I'm currently casually caring for my aunt, who lives by herself in a bona-fide two family. She keeps ideating about "assisted living" but from what I've gathered it would be essentially selling her house to buy in with a large lump payment, and then still paying stiff monthly fees larger than her current expenses (which includes part-time in home help). Essentially the assisted livings have come under control of the same type of economic vampires that have set up shop everywhere else, making it prohibitive for her to move on and consume less housing.
