Detached ADUs are in short supply, and huge demand.
The fact that they are in short supply and high demand should serve as a strong indicator to homeowners and crafty real estate entrepreneurs that there is a real market gap to tap here.
Until the supply has caught up with the demand, expect to pay a little bit of a premium for renting out a detached ADU. Detached ADUs (permitted or not) in the inner Portland market may rent for $800-$1500/month, around $1K/month on average.
Meanwhile, ADU seeker, you’ll just have to do some intensive searching to find this kind of dwelling for rent. Craigslist is probably the best place to search for them. Try using a boolean search like the one below that would show you results that match one of many commonly used terms for ADUs.

Out of frustration at seeing how few of these options there are for you to rent, perhaps you’ll consider eventually building one for yourself. Believe it or not, that’s not an uncommon story of how some ADUs come to be.
