Prefab ADU for Single Family Home

[Samuel Gostnell]

Hello Bigger Pockets!

I am planning on working with a prefab home manufacturer to build a high end small home in Joshua Tree. I've toured a model home, spoken with the company reps and have found yet to find negative reviews. They handle everything from permits to installation, which is very appealing. 

Has anyone had experience with prefab companies, either for ADUs or SFRs? I'd be curious to hear what other people's experience is.
