Here is a good article that discusses the affordability of secondary dwelling units as a follow up to my post.
This might be the “deepest” post in my whole series about research and policy on accessory dwelling units. Though ADUs and affordable housing are often mentioned in the same breath, a closer look at this pairing seems to demonstrate a weakness, not in one policy position or another, but in the whole discussion about affordable housing itself. It takes some work to see how ADUs even fit.
Ultimately, I feel the evidence shows ADUs have tremendous potential for creating reasonably priced housing. Studies in two cities indicate that, without any regulation or subsidy, 15-20% of ADUs are occupied for rents that are zero or far below market rates. But governments and activists need to take time to understand how this form of development is unique. In particular, it is a mistake to assume that the homeowners who create ADUs have the same skills and goals as professional developers.
