Summary
There is no county-wide permit to remove a healthy tree from private residential land in unincorporated Lake County. Removal is restricted mainly where the tree sits in a regulated floodway, drainage easement, or a city with its own tree ordinance. State law separately compels destroying detrimental plants.
A person owning or possessing real estate in Indiana shall destroy detrimental plants by: (1) Cutting or mowing and, if necessary, by plowing, cultivating, or smothering; or (2) Using chemicals in the bud stage of growth or earlier, to prevent detrimental plants from maturing on the person's real estate.
Full Breakdown
Lake County's Unified Development and Flood Damage Prevention ordinances regulate land disturbance in floodplains, drainage easements, and stormwater areas, so clearing there may need Plan Commission or Drainage Board sign-off. Outside those regulated areas, a homeowner generally does not need a county permit to remove a private tree. Cities and towns (for example Munster or Crown Point) may impose their own tree-removal or replacement rules on incorporated parcels. Note IC 15-16-8-3 affirmatively requires owners to destroy detrimental plants such as Canada thistle and Johnson grass.
Violations & Fines
Unauthorized clearing in a regulated floodway, wetland, or drainage easement can draw stop-work orders and restoration requirements under the county's flood and stormwater ordinances.
