The following research aims to follow up on an Accessory Dwelling Unit (ADU) survey project conducted in Portland (city), Oregon, by the Institute for Sustainable Solutions at Portland State University in 2017. In the original survey, we reached out to both ADU owners and residents to define some of their experiences financing, building, owning, and using ADUs.
This poster revisits some of the findings from the original survey, describing ADUs from two perspectives, owner and dweller.
ADUs in Portland are often used for short-term rental (STR) units (in our survey 31% of owners used them as such), however, the city wants to increase their share as long-term rental units, especially in neighborhoods lacking in more affordable, smaller housing options.
In the summer of 2018, the Portland city council enacted a new approach to combat ADU’s use as STR; restricting an existing, decade-long System Development Charges (SDCs) program to serve only those who use their units as long-term rental units.
In this follow-up to the 2017 project, I revisit city permit data to learn of the current effects the change in policy has had on the ADU market in Portland. The assessment tracks the number of permits, types, and locations (citywide analysis based on zip codes).
