Answers from the rulebook for Sparta Township

Rules another office applies inside Sparta Township

Sparta 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

    New construction on private land in unincorporated Knox County, which includes unincorporated Sparta township. Issued by the Knox County Zoning Department, not by Sparta township.

    • Permit is issued under county zoning regulations only. Subdivision covenants and municipal ordinances are not reviewed.
    • Applications must be signed by the landowner or lessee/contract buyer.
    • The zoning page notes that some projects may need an ECO-CAT consultation with Illinois DNR before a permit is issued.

    application fee: 25 USD (non-refundable; applies to all construction applications)

    “No building or structure shall hereafter be erected reconstructed or structurally altered [...] until a construction permit for same has been issued”
  • Local zoningPresent (with conditions)

    Land inside Sparta township outside any municipality with its own zoning. Knox County zoning applies there as unincorporated county land. This is the county rule, not a Sparta township ordinance.

    • The zoning permits page lists the places that have their own zoning: Abingdon, East Galesburg, City of Galesburg, Knoxville, Maquon, St. Augustine, Victoria and Wataga. Sparta township is not on that list. Applying county zoning to Sparta township is an inference from that list, not a statement that names the township.
    • The county issues permits based on county zoning regulations only and does not review or enforce subdivision covenants, restrictions, or municipal ordinances.
