TITLE
Accessory Dwelling Unit (ADU) - 2024 Quarter 3 (July - September 2024) Report
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 quarters 1 through 3 of calendar
year 2024. Since 2015, the City has received 772 ADU/JADU building permit applications and
issued 642 building permits. In quarters 1 through 3 of 2024, the City received 108 new
applications, issued 92 ADU permits, and provided an approved Final Inspection on 75
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 3 quarters of 2024, the ADU sizes of open applications in this period range from 165
to 1,000 square feet, with an average size of 559 square feet. Approximately 45% of
applications are located north of Oregon Expressway, and 55% 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.
