Kane County's property-maintenance code requires exterior wood, doors, trim and metal surfaces to be kept painted and free of rust or decay, and Sec. 15-2E3b folds a specific instruction into that standard: removal of lead-based paint must follow state and federal law, making that requirement enforceable through the county's own nuisance process.
