Full Breakdown
Cook County's Public Health and Private Nuisance Ordinance (Code of Ordinances Ch. 38, Art. II) governs residential composting in the unincorporated area. A compost pile or bin can't exceed five feet in height or a combined 100-square-foot ground base, and it must be structurally sound and kept in good repair. Placement is restricted to the rear yard, the front yard and side yard are both off-limits, and bins can't sit over a drainageway. Only material generated by residents of that property may go in the bin: grass, leaves, non-diseased plant waste, food scraps and similar organics are fine; meat, dairy, grease, pet or human waste and treated lumber are not. The Cook County Department of Public Health inspects and cites noncompliant piles.
Violations & Fines
Composting improperly, oversizing a bin past 5 feet tall or 100 square feet, or placing one in a front/side yard or over a drainageway is a declared nuisance drawing a CCDPH citation and a $350-$1,000 fine for a first offense.
