The main issue is that to do the ADU you have to spend so much bringing other items up to code like electrical, plumbing, lighting (windows) and egress.

I attended the RALA 3-day training in Phoenix and took a couple of online courses as well, and while I found these courses to be very valuable in helping get a clearer understanding of the space and what it might take to be successful, I eventually I found it most beneficial to bring in a partner/advisor who has built residential assisted living facilities here in Texas and has been running them successfully.
