Champaign caps lawn grass at eight inches; taller triggers a code-compliance notice and city mowing billed to the owner. Urbana, Rantoul, and the county's unincorporated townships run parallel weed-and-rank-vegetation nuisance rules across this prairie farm county.
Champaign's yard-maintenance code sets a hard number: grass-type ground cover on private lots must stay at or below eight inches, and non-turf plantings in the parkway may not exceed 24 inches, with flower blossoms capped at 36 inches. Code compliance works by complaint and survey, mails a warning, and gives about ten days to cut before the city mows and bills the cost. Urbana and Rantoul enforce their own overgrowth ordinances, and Champaign County addresses tall weeds on unincorporated parcels as a nuisance. The Illinois Noxious Weed Law (505 ILCS 100) sits underneath all of them.
A warning letter starts a roughly ten-day clock. Miss it and the city mows or clears the lot, then charges the owner the cost plus an administrative fee, filing a lien if unpaid.
