Tree removal permit rules in O'Fallon, IL — sometimes called heritage tree, protected tree, or street tree ordinances — list which trees require a permit before you can cut them down.
St. Clair County does not require a permit to remove trees on private unincorporated land, and has no county tree-preservation ordinance. Removing trees on public land or street/parkway trees requires municipal permission. Inside cities, check that municipality's tree rules.
There is no St. Clair County ordinance mandating a permit or mitigation for removing trees on private property in the unincorporated county; land-use is governed by the county Zoning Ordinance, which addresses structures and setbacks rather than tree preservation. Removing or altering trees on public land or in the parkway is restricted to authorized municipal crews or requires a public-works permit from the relevant city. Because rules differ sharply by municipality, residents of Belleville, O'Fallon, Fairview Heights or other incorporated places should confirm any local tree-removal or heritage-tree ordinance directly with the city before cutting.
No county fine for removing your own private tree. Damaging or removing a public/street tree without authorization can bring municipal penalties and restitution.
