DuPage County, IL Landscaping Rules: Native Plants (2026)

Sec. 8, 'Motor Vehicles,' from Section 302, 'Exterior Property Areas,' in their entirety. The IPMC's standard weeds provision is the model code section that typically caps grass and weed growth at a fixed height and lets a building official order it cut; DuPage County struck it before adopting the rest of Chapter 3. The remainder of Section 302, including exterior-property maintenance standards the county kept, remains enforceable, and Sec. 8-900's Section 310 amendment still lets the Building Official act against a genuine 'public nuisance,' defined as a structure that is a menace to health, safety or welfare through unsafe conditions, fire hazard or disrepair, not against unmowed vegetation on its own.

4 would be. This is a county-code gap rather than an affirmative 'natural landscaping' permit: nothing in Chapter 8 requires registering a native planting plan, and the deletion applies only to unincorporated territory under direct county jurisdiction, not to any incorporated DuPage municipality that adopted its own weed ordinance separately.
