Summary
Naperville's weed ordinance caps plant height at 8 inches citywide, but common garden crops are expressly exempt, so front yard vegetable gardens are legal year-round without a height violation.
It shall be unlawful for anyone to permit any weeds, grass or plants, other than trees, bushes, flowers, shrubs, vines, ground cover, common garden crops such as farm food, or other ornamental plants to grow to a height exceeding eight (8) inches anywhere in the City, except in designated natural landscape areas, in median strips or on private naturally landscaped lots, as described in Subsections 4-3-2.5 and 4-3-2.6 of this Section...
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 101).
Full Breakdown
Naperville's general weed and plant ordinance, City Code § 4-3-2, bans letting weeds, grass, or plants grow past 8 inches anywhere in the city, but the same subsection exempts trees, shrubs, flowers, ground cover, and 'common garden crops such as farm food' from that limit. That exemption is what makes front-yard vegetable gardens lawful. Parkway strips get a separate rule: owners must keep the strip between curb and sidewalk clear of growth over 8 inches, except flowers up to 18 inches. Violations start with a written notice to abate before any fine.
Violations & Fines
Weeds or plants over 8 inches (except exempt garden crops) draw a written abatement notice; unresolved violations bring city mowing plus a $90 fee and fines of $100–$500 per offense.
