Summary
Oak Lawn caps weeds on any real estate, including vacant lots, at four inches and lets the Village cut, bill, and lien noncompliant property after a three-day notice.
It shall be the duty of every owner of real estate or person having a beneficial interest therein to cut, control, or otherwise provide for the destruction and proper disposal of weeds on his property at all such times as may be necessary so that such weeds shall not exceed four inches (4") in height, and should said owner or person fail to comply with the requirements of this chapter, then the Village shall cause the weeds to be destroyed, cut or controlled.

Full Breakdown
Village Code Chapter 8-6 requires every owner of real estate, including unimproved vacant lots, to keep weeds and grasses under four inches high; letting them grow taller is declared a nuisance under section 8-6-3. If an owner ignores a mailed notice (or, on a vacant lot with no door, a notice posted in a conspicuous place) for three days, Village crews cut the lot themselves and bill the owner, recording a lien with the Cook County Recorder of Deeds if the bill goes unpaid for thirty days. A companion provision, section 8-8-2, lets the Village similarly order debris, abandoned material and overgrown foliage cleared from vacant lots.
Violations & Fines
Overgrown weeds are declared a nuisance; the Village abates and bills the owner, adding 1% monthly interest, and after 30 days unpaid records a lien with the Cook County Recorder of Deeds.
