In unincorporated St. Clair County, it is a nuisance to let weeds on a residential subdivision lot exceed eight inches (SCC 25-1-2), and the Property Maintenance Code bars weeds or plant growth over 12 inches on all premises (SCC 29-3-7). Owners get a notice and 10 days to cut.
Two county provisions set weed and grass limits outside city limits. Nuisances Chapter 25, Article I declares it a nuisance for owners of residential subdivision lots to let listed weeds exceed eight inches, with a written notice and 10 days to cut before the county abates and liens the cost. The Property Maintenance Code (29-3-7) separately requires all premises and exterior property be kept free of weeds or plant growth over 12 inches, excluding cultivated flowers, gardens, trees and shrubs. Municipalities set their own grass-height rules within city limits.
Uncut weeds after notice: the county may cut and charge/lien the cost (SCC 25-1-5). Property Maintenance weed violations are petty offenses (SCC 29-1-36).
