Hamilton County has no single grass-height rule; the cities set the limit. Carmel requires cutting weeds and rank vegetation that exceeds an average height of six inches, and Fishers acts on grass or weeds over eight inches. Unincorporated land falls under the county weed board.
Because Hamilton County is heavily incorporated (Carmel, Fishers, Westfield, Noblesville), grass height is a city matter, not a countywide ordinance. Carmel City Code 6-88(c) requires all owners of real property in the City to cut and remove weeds and other rank vegetation exceeding an average height of six inches. Fishers, under its high-weeds ordinance (Ord. 120511A), enforces against grass, weeds, or rank vegetation that exceeds a height of eight inches, excluding wetlands, woods, nature preserves, undeveloped areas, and agricultural crops. For unincorporated Hamilton County parcels, the township trustee and county weed control board act under Indiana Code 15-16-8. Cities typically send a notice giving the owner a few days to cut before the City mows and bills the owner.
After notice, if the owner fails to cut, the City (or trustee) mows the property and bills the owner, adding an administrative fee. Unpaid charges become a lien or certified to the county tax duplicate.
