That's a good point. Though Portland is pretty affordable vs. a lot of others.

And a huge reason to get rid of any parking requirement. With smaller housing, an off-street parking space would be a huge percentage of overall cost, in addition to the geometry challenge.

Even with the expense, a lot of ADUs are new construction vs. squeezing in that little house off the alley or converting the basement. I wonder how banks look at that, both for families trying to build new places with a little income potential and developers doing a lot of these.
