We looked and could not find an official answer yet. Silence is not permission; ask Echo or Umatilla County directly.
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.
Unanswered questions are usually a sign that Echo publishes no rule on the point, not that none exists. Umatilla County’s page lists the county offices to call.
