Answers from the rulebook for Town of Modoc

Town of Modoc’s own rules

  • Building permitRequired

    New construction, placement, or enlargement of buildings and structures on land inside Modoc town under the joint Randolph County UZO; the improvement location permit is issued by the Area Planning Commission of Randolph County

    • Construction may proceed after the improvement location permit is approved.
    • Other approvals (septic approval under section 10.04) are preconditions for the permit.
    “no land, building, structure, swimming pool, lake or pond, premises or use shall be hereafter located, erected, moved, reconstructed, extended, enlarged or altered unless and until an improvement location permit has been approved”
  • Local zoningPresent (with conditions)

    Land inside the limits of Modoc town, Indiana, under the joint Unified Zoning Ordinance of Randolph County, Indiana, which names the Town of Modoc as a covered jurisdiction and is administered by the Area Planning Commission of Randolph County. Not unincorporated county land.

    • This is a joint county and town ordinance, not a standalone Modoc town code.
    • Section 14.06 repeals the prior zoning ordinance of the Town of Modoc, so the joint ordinance replaces any separate Modoc zoning ordinance.
    • The Town of Modoc's own legislative adoption of the joint ordinance was not found in a town source.
    • The text opened is the 2018 revision; no post-2018 amendment was located.
