Full Breakdown
Cincinnati splits composting into two tiers by size. Composting under 500 square feet is 'Accessory Composting,' defined and regulated at § 1422-07(d) within Chapter 1422, Urban Agriculture: Horticulture and Animal Keeping. Anything at or above 500 square feet becomes a licensed 'Composting Facility' under the separate § 1419-38, which requires an Ohio EPA Division of Materials and Waste Management license and a 100-foot setback from residential property, that heavier regime doesn't apply to an ordinary backyard bin. For accessory composting, § 1422-07(d)(2) sets six location standards: the pile or bin may sit no more than 30 feet from the rear lot line, must stay at least 10 feet from both side and rear lot lines, at least 10 feet from any principal structure, at least 5 feet from any accessory structure, at least 20 feet from a natural watercourse or wetland, and at least 50 feet from any private water supply system.
Subsection (d)(3) limits what can go in the pile to plant-derived materials only, and requires management to comply with Cincinnati Board of Health regulations. Subsection (d)(4) requires the compost to be contained and managed within an appropriate enclosure, container or structure, using best practices, an open, unenclosed pile does not comply. The section was ordained by Ord. No. 251-2019 and amended by Emergency Ord. No. 418-2021.
Violations & Fines
Composting setback and containment violations are enforced as Zoning Code violations under § 1451-09: a first offense is a misdemeanor of the third degree, repeat offenses escalate to a misdemeanor of the first degree, and each day of noncompliance is a separate offense. Composting more than 500 square feet without the required Ohio EPA license instead exposes the operator to Composting Facility enforcement under § 1419-38, including state EPA action.
