Answers from the rulebook for Pecatonica Township

Rules another office applies inside Pecatonica Township

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

  • Local zoningPresent (with conditions)

    Land inside Pecatonica township that is outside village limits (unincorporated Winnebago County), where county zoning is administered by the Winnebago County Planning & Zoning division

    • The county planning page says property inside village or municipal limits is zoned by that village or municipality, so this claim does not cover land within the Village of Pecatonica.
    • The page does not state whether Pecatonica township has adopted its own zoning, so this claim is not a finding that the township has none.
    • The county zoning text (Chapter 90) was not opened; its district standards are not stated here.
    “the county is divided into agricultural, residential, commercial and industrial districts, with several classifications in the latter 3 districts allowing varying intensities.”
  • Zoning districtsPartial

    Zoning districts applying to unincorporated land inside Pecatonica township

    • The county page names agricultural, residential, commercial and industrial district groups and says Chapter 90 lists permitted and special uses for each district; the district map and Chapter 90 text were not captured, so the list is partial.
    • Land inside the Village of Pecatonica is zoned by the village, not by these county districts.
    “the county is divided into agricultural, residential, commercial and industrial districts, with several classifications in the latter 3 districts allowing varying intensities.”
  • Who permits septicCounty (with conditions)

    Private sewage (septic) systems on land inside Pecatonica township, as overseen by the Winnebago County Health Department

    • The cited page says the health department inspectors oversee licensed well and septic contractors and private water and sewage systems; it does not state a service-area boundary, so applicability to Pecatonica township is inferred from county-level jurisdiction.
    • Illinois state private sewage rules were not researched and may also apply.
    “wells and septics our inspectors oversee all licensed well and septic contractors to ensure proper installation and repair of private water and sewage systems, conduct loan inspections, and site verifications.”
  • Subdividing landRegulated (with conditions)

    Subdivision of land on unincorporated land inside Pecatonica township

    • The county planning division provides subdivision services for unincorporated land; subdivision in village limits is handled by the village.
