Kendall County, IL Landscaping Rules: Weed Ordinances (2026)

Most counties that adopt the International Property Maintenance Code inherit Sec. 4, the model provision that caps weeds and uncultivated vegetation at a set height. Kendall County did not: Kendall County Code § 8-64, the ordinance that adopts the 2024 IPMC for the unincorporated county, lists 'Sec. 4 "Weeds" delete' among its amendments, right alongside deletions of Sec. 8 Motor Vehicles, Sec. 308 Rubbish and Garbage, Sec. 309 Pest Elimination, Sec. 310 Accessibility and Sec. 311 Storm Shelters. That means the Planning, Building and Zoning Department, which administers Chapter 8 and Chapter 36 zoning together, has no weed-height standard to cite against a homeowner in unincorporated Kendall County the way IPMC Sec.

4 would otherwise allow. This is a county-level absence only: Oswego, Yorkville, Plano, Montgomery, Plainfield, Joliet and the county's other municipalities each administer their own codes within their corporate limits and may retain a weed ordinance the county chose to drop. A property in unincorporated territory can still be pursued under Chapter 18's public health nuisance provisions if overgrown vegetation becomes a harborage for vermin under Sec. 18-23, but that is a general nuisance standard, not a specific height limit.
