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

• Owner-builder exemption — Owner-built homes inside Kiel city limits
• Certificate of occupancy — New construction inside Kiel city limits
• Zoning districts — Zoning districts of Kiel city
• Minimum dwelling size — Single-family residential district inside Kiel city limits
• Minimum lot size — Single-family residential district inside Kiel 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.
