Thanks for the thoughts. As always, I'm thankful for the wide range of experience and helpful replies on this and other topics.

I'm going to meet with some folks knowledgeable about ADUs in Portland, maybe next week.

I understand the concern about stairs. My experience is that old people start having accidents on stairs, before they actually lose the strength to climb them. My father fell on the stairs to my third floor on his last visit, he went to turn off a fan located near the stairs, forgot there were stairs there, slipped off the top step and ended up at the bottom in a pile of broken glass from several framed pictures that he took down with him. Cut his scalp, broke bones in his foot, couldn't walk much for months. My stepmother fell down the stairs from my second floor a few years ago, just missed the last step for no clear reason, fractured her leg.

But my house has stairs everywhere, just to get into the house from the street you have to climb a few steps, and then inside is three floors, and it would be very hard to build an ADU without stairs. I have thought about leaving room for a lift from basement to first floor, of some sort, in case one is later needed.
