Cincinnati, OH Invasive Plant Rules: Prohibited Species (2026)

Section 1422-13 sits in Chapter 1422, Cincinnati's Urban Agriculture: Horticulture and Animal Keeping chapter, immediately after the chapter's maintenance and sales provisions. ' The section doesn't define 'invasive species' or list covered plants and animals itself, it incorporates Ohio's statutory and administrative invasive-species framework by reference, meaning the state list, not a Cincinnati-specific one, determines what a gardener, farmer or animal keeper can't bring onto or sell from the property. The rule applies to any site operating under Chapter 1422, whether it's a small residential Garden (under 20,000 square feet of cultivated land), a larger Farm, or an Animal Keeping Facility, and it runs alongside the chapter's other site-maintenance duties: § 1422-07 already requires every Garden, Farm or Animal Keeping site to be kept free of high grass, weeds and debris, with dead plant growth trimmed to six inches or less and cleared by December 1st each year.

Chapter 1422 was adopted by Ordinance No. 251-2019, effective July 26, 2019, as part of the city's push to make urban food production easier while keeping it compatible with surrounding neighborhoods, the invasive-species ban is one of the chapter's guardrails against introducing new nuisance or ecologically harmful plants and animals through that expanded permission.
