We looked and could not find an official answer yet. Silence is not permission; ask King City or Washington County directly.

• Owner-builder exemption — Owner-built residences inside King City city limits.
• Building code adopted — Construction inside King City city limits.
• Inspections — Building inspections inside King City city limits.

Each answer was extracted from an official source and independently re-checked against that source by a second reviewer. That is an evidence check, not legal advice. Rules change; confirm with the authority before you buy or build.
