Has anybody built apartments with Modular/Manufactured units?

[David Friedman]

I am looking to develop 40+ units on approximately an acre of land in California. In the past two years, I've started to see a lot of new modular construction startups in California. I am considering using a modular construction company to build these apartments, but so far, most of them seem to be focused on ADU or luxury modular builds.

Does anybody have experience building multifamily housing? Was it more cost effective than building on-site? Do you think the future of construction is going to be modular (Built off-site)? Why or why not? Other states can pitch in as well! California has notoriously expensive costs to build.
