Commission workshop explores ADU code changes — size, parking, prefabs and penalties

Aug 27, 2026

At a long workshop, staff outlined state code triggers for ADU updates and proposed using gross living area to define ADU size, parking by unit square footage, conversion rules for existing accessory structures, and deleting the discretionary CUP in favor of clear standards; commissioners debated raising a 1,200‑sq‑ft cap to roughly 1,400–1,450 for larger lots.

The full story

Staff opened a workshop on accessory dwelling unit (ADU) standards on Aug. 26, explaining that recent state code changes require jurisdictions to allow detached and internal ADUs and to modify parking calculations. Staff recommended defining ADU size by gross living area (excluding garages), updating parking to the state‑required square‑foot approach, adding conversion rules for legally established accessory structures, and considering whether to remove the CUP exception for oversized ADUs in favor of measurable standards.
