TITLE
Accessory Dwelling Unit (ADU) - 2024 Quarter 2 (April - June 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 the first half of calendar year 2024.
Since 2015, the City has received 736 ADU/JADU building permit applications and issued 557
building permits. In the first half of 2024, the City received 72 new applications, issued 57 ADU
permits, and provided an approved Final Inspection on 46 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.
Of the applications submitted in the first half of 2024, the ADU sizes range from 165 to 1,000
square feet, with an average size of 517 square feet. Approximately 43% of applications are
located north of Oregon Expressway, and 57% 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.
