We looked and could not find an official answer yet. Silence is not permission; ask Town of Oregon or Dane County directly.

• Building permit — Building permits for new construction inside Oregon town
• Owner-builder exemption — Owner-builder permit exemption for Oregon town
• Inspections — Building inspections for work inside Oregon town
• Certificate of occupancy — Occupancy approval for new homes in Oregon town
• Local zoning — Whether Oregon town itself adopts and administers a zoning ordinance for land inside its 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.
