Still unanswered

We looked and could not find an official answer yet. Silence is not permission; ask Brewster or Okanogan County directly.

• Building permit — Residential construction inside Brewster city limits.
• Owner-builder exemption — Owner-built dwellings inside Brewster city limits.
• Building code adopted — Construction inside Brewster city limits.
• Inspections — Construction inside Brewster city limits.
• Certificate of occupancy — Occupancy of structures inside Brewster 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.
