Cincinnati, OH Landscaping Rules: Weed Ordinances (2026)

City Municipal Code § 731-3 requires every owner or person in control of any lot or land in Cincinnati to keep it free of weeds and turf grasses over 10 inches tall by cutting and removing the clippings immediately. A property that isn't brought into compliance within seven days of a notice of civil offense and civil fine under § 731-1-A is reclassified as "Abandoned Property," and the threshold then drops to 6 inches under § 731-3(b). Each day a violation continues, and each separate lot an owner controls, counts as a separate offense under § 731-3(c).

Enforcement runs through the city manager's designee: an initial notice under § 731-5(a) gives the owner seven days to cut and remove the growth, and once a property is Abandoned, a fresh notice issues every time a subsequent violation is found under § 731-5(b). An owner can answer a notice within seven business days under § 731-6, including offering proof of correction on an Initial Violation. If the owner does nothing, the city (or a city-authorized designee who is immune from trespass liability under § 731-10(c)) cuts the growth, and the cost, plus service and administrative/inspection costs, becomes a lien on the land under § 731-11, certified to the Hamilton County auditor for collection with property taxes, or pursued as a personal judgment.

Section 731-4 carves out an exception: natural plants on privately owned, occupied residential property that qualify as a "Managed Natural Landscaped Area" are exempt from the height cap if set back at least 3 feet from property lines, roads, alleys and driveways (or planted to the property line behind a fence), and right-of-way strip vegetation between sidewalk and street is still capped under 10 inches. Civil fines collected go into the Stormwater Management Fund 107 under § 720-51.
