Summary
Unincorporated DuPage County residents report a public nuisance by complaining directly to the chairman of the County Board, who must notify the sheriff or another designated county official to inspect. A confirmed violation triggers a written report and a court abatement action.
Whenever a complaint is made to the chairman of the DuPage County Board that a public nuisance exists, or has existed, as enumerated in section 26-3 of this chapter, within DuPage County, he shall promptly notify the sheriff or some other County Official whom the chairman shall designate, who shall forthwith make such inspections as permitted by law.
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 14 Update 1).
Full Breakdown
" There is no online portal named in the ordinance; the complaint runs through the Board chairman's office, and the sheriff's office or the designated official conducts the field inspection. If that inspecting officer has reason to believe a nuisance exists, Section 26-5 requires a written report back to the chairman, who then causes an abatement action to be commenced in the County's name, meaning the case moves from complaint to a court filing rather than an internal administrative ticket. This chapter applies within unincorporated DuPage County and the county's police jurisdiction; residents inside Naperville, Wheaton, Downers Grove and the county's other home-rule municipalities report to their own city hall instead, since those cities enforce their own nuisance codes.
Violations & Fines
Section 26-6 sets the penalty on conviction at not more than $1,000.00. Once the owner (or, if the owner cannot be found, the occupant or person causing or permitting the nuisance) has been notified, every day the nuisance is not abated is a separate offense, and the fines are cumulative rather than capped at one $1,000 total.
