Rules another office applies inside Freeburg Township

Freeburg 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 zoningVaries (with conditions)

    Land inside Freeburg township outside the Village of Freeburg limits (unincorporated St. Clair County portion). No Freeburg township zoning ordinance was located.
