Answers from the rulebook for Bennington Township

Rules another office applies inside Bennington Township

Bennington Township does not set these itself; the county, a health district or the state does, and they apply to every address inside its limits.

  • Building permitRequired

    Land use and building permits for buildings and structures on land in the unincorporated part of Bennington township, Marshall County, Illinois

    • The rule sits in the county zoning ordinance, so it applies only where that ordinance is in effect (the unincorporated area).
    • In agricultural districts the requirement is a written notification rather than a full application (see the agricultural_exemption claim).
    • Any permit issued in conflict with the ordinance is null and void.
    “no permits pertaining to the use of land or buildings shall be issued, by any officer, employee, department, board or bureau of the county, unless a building permit has been obtained from the office of the zoning administrator.”
  • Zoning districtsPublished

    Zoning districts that the Marshall County zoning ordinance establishes for land in the unincorporated part of Bennington township, Marshall County, Illinois (county-administered; the district map is the county GIS zoning layer)

    • The county ordinance applies only to the unincorporated area; municipalities with their own zoning are excluded.
    • The map index of the county zoning ordinance lists a Bennington township zoning map (page 4); the district assigned to any specific parcel was not checked.
