The Institute for Sustainable Solutions is spearheading an initiative to make it easier and more affordable for Portland homeowners to construct a second house on their property—increasing housing options in a city with some of the fastest rising rents and lowest vacancy rates in the nation.

Called “accessory dwelling units” or ADUs, these small backyard homes can be used by family members or rented out to others in the community. They provide more affordable housing options while reducing pollutants that cause climate change.

In 2018, Matthew Gebhardt, assistant professor of Urban Studies and Planning, and Yael Kidron, Ph.D. candidate in Urban Studies and Planning, conducted a survey of ADU owners and tenants in Portland. The survey was conducted as part of the Institute's Small Backyard Homes Project which is focused on encouraging ADU development for a more sustainable and equitable city. The City of Portland has been a national leader in ADU development, and the survey is the first of its kind—targeting not only ADU owners but those who live in ADUs as well.
