Summary
Oak Lawn caps weeds at 4 inches tall on private property, the abutting parkway, and abutting alleys, and can cut them itself and bill the owner.
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 § 8-6-2 makes every property owner responsible for cutting or destroying weeds so they never exceed 4 inches in height; if an owner fails to comply, the Village cuts them itself. § 8-6-3 makes it illegal and a nuisance to let weeds on the property, abutting parkway, or abutting alley exceed 4 inches. Enforcement runs through § 8-6-4: after 3 days' mailed notice to the owner of record and a posted notice, the Village can cut the weeds and bill the cost, with a lien filed against the property in the Cook County Recorder of Deeds office if the bill goes unpaid 30 days, carrying 12% annual interest. § 8-6-5 exempts land the Board of Trustees designates a botanical or ecological area.
Violations & Fines
Weeds over 4 inches on your lot, parkway, or abutting alley violate § 8-6-3. The Village can cut them after 3 days' notice and bill you; unpaid bills become a recorded property lien at 12% annual interest under § 8-6-4.
