Randolph County, Indiana

We looked and could not find an official answer yet. Silence is not permission; ask Town of Modoc or Randolph 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.
