ADU policy earns support as attainable option while members press for fiscal analysis

Committee members confirmed accessory dwelling units (ADUs) are now allowed by right across residential districts, including R-10, R-5 and RU after recent code changes. Supporters said ADUs offer a plausible pathway to smaller, attainable housing—one member argued an ADU can let a parent build a backyard home for a daughter rather than rely on high-priced market housing and said “ADU is a pretty good option.”

Opponents and fiscally minded members emphasized county revenue and service-cost implications. One member noted the county’s per-student cost figure discussed in the meeting—"$13,100 per student"—and argued residential growth, including ADUs, could increase demand for schools and other services and potentially produce net “red ink” for county budgets unless carefully modeled. Staff agreed to run a cost-of-service analysis for residential units (including potential school, public safety and service costs) before finalizing housing recommendations.

Why it matters: ADU policy changes can increase housing choices locally but have direct fiscal implications. The committee asked staff to quantify net fiscal impacts and to ensure the county understands both housing accessibility benefits and service-cost tradeoffs.
