Summary
Owners of vacant and unimproved property in the Village of Oak Park must keep weeds, including grass, cut to under 8 inches. The Village can mow and spray a noncompliant lot itself, lien the property for the cost, and cite the owner up to $750 per violation.
It is hereby declared to be illegal for the owners of real estate to refuse or neglect to cut weeds when such weeds shall have reached a height in excess of eight inches (8"). For the purpose of this article only, the term weeds shall include grass. ... In the event the owner of property neglects or refuses to cut weeds so that such weeds exceed eight inches (8") in height, the Village may cause such weeds to be cut, and thereafter in order to reduce costs and the subsequent nuisance of a further growth of weeds, may cause said lot to be sprayed with weedkiller even though at the time of spraying there is no visible growth of weeds. ... Any person may avoid prosecution for the violations of this article by paying to the Village the sum of one hundred and twenty five dollars ($125.00) if paid within ten (10) business days after receipt of the citation. The maximum penalty for any violation of this article shall not exceed seven hundred and fifty dollars ($750.00).

Full Breakdown
Oak Park Village Code § 20-7-14, in the Public Health chapter's litter and nuisance article, makes it illegal for real estate owners to refuse or neglect to cut weeds once they exceed 8 inches in height, and for purposes of this article defines "weeds" to include grass, a broader sweep than the Property Maintenance Code's separate cultivated-garden carve-out. If an owner of a vacant or neglected lot does not cut the growth, § 20-7-15 lets the Village cut the weeds itself and, to reduce recurring costs, spray the lot with weedkiller even when no weeds are visibly growing at the time; that spraying can continue year to year until the owner resumes maintenance and notifies the Village in writing.
Under § 20-7-16, the cost of Village-performed cutting or spraying becomes a recorded lien against the property. Enforcement duty is spread across five Village departments under § 20-7-19: Police, Housing Division, Building and Zoning Division, Health Department, and Public Works. Owners can avoid full prosecution under § 20-7-20 by paying $125 within 10 business days of receiving a citation; if that window passes, the maximum penalty for a violation of the article rises to $750.
Violations & Fines
A citation for uncut weeds on a vacant lot can be resolved for $125 if paid within 10 business days; otherwise the owner faces prosecution with a maximum penalty of $750 per violation, plus a recorded lien for any cutting or weedkiller spraying cost the Village incurs to abate the lot itself.
