RECOMMENDATION
This is an informational report, and no action is required.
ANALYSIS
This report transmits information related to application activity for accessory dwelling units
(ADU), including junior accessory dwelling units (JADU) for quarter 1 of calendar year 2024. Since
2015, the City has received 702 ADU/JADU building permit applications and issued 524 building
permits. In the first quarter of 2024, the City received 38 new applications, issued 24 ADU
permits, and provided an approved Final Inspection on 22 ADU/JADU permits. As it relates to the
Housing Element, the data continues to support the anticipated housing unit production
expected from ADU/JADUs for the current housing element cycle, which is an average of 64 units
per year over the 8-year planning period or a total of 512 units.
In the first quarter of 2024, the ADU sizes of open applications in this period range from 196 to
1,000 square feet, with an average size of 554 square feet. Approximately 58% of applications
are located north of Oregon Expressway, and 42% are located south of Oregon Expressway. Since
2017, the majority of ADU/JADU permits relative to the Oregon Expressway has shifted between
north and south from year to year. Further details can be found in Table 1 of Attachment A.
