Council Session - Jun 9, 2026
The county is updating ADU rules to comply with 2025 state law — bigger units, more zones allowed — but speakers pressed the council to go further and kill the owner-occupancy requirement they say has stalled ADU production (only about 222 ADUs since 2019).
Council Session - Apr 21, 2026
Two new zoning text amendments were introduced: ZTA 26-06 on accessory dwelling units (in-law suites, backyard cottages) and ZTA 26-07 on solar collection system standards. Public hearings are June 9 — residents can weigh in then.
