Summary
Champaign caps vegetation on private property at 8 inches tall under Sec. 35-19(a)(7), with an exception for maintained 'alternative vegetation' that meets the chapter's other standards. The parkway strip next to the street is held to the same 8-inch cap, plus a 24-inch limit on shrubs, under the companion rule at Sec. 35-18.

Full Breakdown
Sec. 35-19 requires every property owner to keep vegetation from growing past 8 inches, with the code presuming anything taller is not qualifying 'alternative vegetation' unless it is predominantly composed of those approved species. Owners must also trim vegetation, trees, and shrubs to keep a minimum overhead clearance of 8 feet over sidewalks and 14 feet over streets and alleys. The parkway between the curb and the sidewalk carries the same 8-inch vegetation cap and a 24-inch shrub cap under Sec. 35-18, which owners are responsible for maintaining even though the strip is City right-of-way.
Sec. 1 declares any vegetation violating the chapter a public nuisance and states offenses under the article are 'absolute liability offenses,' meaning intent is not a defense. Enforcement runs through Chapter 22's nuisance process: the Neighborhood Services Director can issue a notice to abate under Sec. 22-56, giving the owner 10 days to cut the growth, or 24 hours if the violation is a repeat at the same address within 12 months. If the owner doesn't comply, the City can enter the property, mow or clear it, and bill the owner for the cost under Sec. 22-58, with any unpaid balance becoming a lien on the property under Sec. 22-59.
Violations & Fines
A citation for overgrown vegetation is treated as an absolute liability offense under Sec. 35-24.1, so lack of intent is not a defense. Because no specific fine is listed in Table I for this section, the general penalty under Sec. 1-21(c) applies: $1.00 to $750.00 per offense. If the owner misses the 10-day (or 24-hour repeat) abatement deadline, the City can clear the lot itself and lien the property for the cost.
