Kol Peterson, one of the editors here, is hosting a class called “Building An Accessory Dwelling Unit on your property,” on Saturday, June 17th. Please visit Kol’s site for more details. Advertisements
I’m semi-retiring as a co-editor and numbers guy at accessorydwellings.org . But the site is alive and well.
It’s not intuitive, but prohibiting short-term rentals in ADUs won’t necessarily lead to a bigger supply of long-term residential housing. This post includes new data about the number of ADUs and short-term rentals in Portland, and the longevity of short-term rental listings.
Up for rent in Portland, February 2015: a tiny purple structure in someone’s backyard, apparently a converted garden shed. At 165 square feet, it had the same area of 5 … Continue reading
Collected research about accessory dwelling units (AKA granny flats, laneway houses, in-law units, etc) suggests they have many potential benefits, and two common arguments “against” are unsupported.
ADUs are especially promising as environmentally sensitive and affordable housing, and this potential should be investigated in detail.
Government rules strongly limit the development of ADUs, but they are not the only factor.
If the “grassroots” nature of their development is properly understood, ADUs have a lot of potential to address affordable housing needs.
Will building an ADU raise your property taxes? Very likely yes. Is that a good thing for the community?
Older persons are expected to benefit from ADUs. Is this happening now, and will it happen more in the future?
The single biggest and most specific fear mentioned by ADU opponents is loss of street parking. Is there any evidence on this?
New evidence shows that ADUs have serious potential as environmentally sensitive housing.
Opponents of ADUs frequently charge they will bring down property values for the whole neighborhood. What is the evidence?
Some survey results about ADU costs… and some thoughts about why ADU developers aren’t usually real estate “pros.”
It may seem odd to ask whether a housing form actually provides housing, but it’s a key premise in civic debates about accessory dwelling units.
ADUs are a really unusual form of development. This post goes over their special qualities, and explains why a lot of “debate” about ADUs is so repetitive.
Which hopes and fears about ADUs are most likely to be true? Explore claims and controversies with new evidence, in this 13-part series, beginning today.
