I don't think it's intended to require interacting with an object but things can be bugged. Interacting with an object ends up a safety measure.
As far back was I can remember, we had to interact with something in the house to count as having been in it. Because of that, I always sent my retainers out on ventures right before logging out to make sure the game knew I was in there.
