Commission debates ADU size limits, setbacks and parking

Oct 1, 2026

Commissioners discussed maximum ADU size caps (1,500 sq ft accessory limit versus alternatives like 900 sq ft or a percentage of the principal dwelling), setbacks and height (accessory max height 17 ft; principal max 35 ft), and parking/utility considerations; staff will provide size examples and visuals at the next meeting.

The full story

Commissioners spent a substantial portion of the meeting discussing ADU size limits, building design, setbacks and parking. Several commissioners said the existing accessory-structure cap of 1,500 square feet may be too large for an ADU and suggested alternative approaches such as a percentage cap (for example, 75% of the principal dwelling) or absolute caps near 900 square feet.
