Two layers apply: statewide, IC 15-16-8-3 requires every Indiana landowner to destroy detrimental plants, which in residential areas include noxious weeds and rank vegetation; locally, St. Joseph County's 2022 ordinance enforces a 9-inch limit in unincorporated residential yards.
Indiana defines a short list of detrimental plants at IC 15-16-8-1, including Canada thistle, Johnson grass, and, in residential areas only, noxious weeds and rank vegetation, and IC 15-16-8-3 obligates every landowner to destroy them by cutting, mowing, or chemical treatment before they mature. A township trustee can order abatement and bill the cost as taxes. On top of that state duty, St. Joseph County's 2022 Weed and Rank Vegetation Control Ordinance sets a concrete 9-inch trigger for unincorporated residential parcels around Granger and Clay Township, with exemptions for cultivated landscaping, native and pollinator gardens, rain gardens, and natural wooded areas. South Bend, Mishawaka, and Walkerton enforce their own municipal weed codes.
The county gives written notice and 10 days to cut or file a plan, then abates and bills the owner; repeat offenders face fines of $100, $200, and $500. State detrimental-plant duties are enforced by the township trustee.
