Answers from the rulebook for Linn Township

Rules another office applies inside Linn Township

Linn 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

    Construction of buildings or structures on unincorporated land in Linn township, Woodford County, IL; the county zoning permit applies there, not in any incorporated city or village

    • Applies only to unincorporated land; the county FAQ says property in a city or village should contact the local jurisdiction.
    • A zoning permit is required before construction; construction may proceed after the permit is issued.
    • Zoning permits for dwellings also require a septic permit and soil erosion permit first (see septic_permit claim).
    “no building or other structure shall be erected, constructed, reconstructed, altered, converted, removed, added to, used or the use therein changed unless and until a zoning permit is obtained from the zoning administrator.”
  • Zoning districtsPublished (with conditions)

    Land in unincorporated Linn township, Woodford County, IL (county zoning districts apply only in unincorporated areas; not a township-adopted district map)

    • The county zoning district map governs unincorporated land; land inside a city or village is handled by that municipality.
    • The ordinance defines districts by reference to the county zoning district map; the map itself was not opened, so district names and boundaries for Linn township are not listed here.
    • The A1 and A2 district sections were not located in the text of Chapter 154 during this run; district-specific dimensional and use rules are unresolved (see followups).
