Cincinnati, OH Property Maintenance: Vacant Lot Maintenance (2026)

Chapter 731, "Weed Control," sets a citywide height ceiling rather than targeting only vacant parcels: § 731-3(a) requires every owner or person in control of "any lot or lands within the city of Cincinnati" to keep weeds and turf grass cut to 10 inches or less, and to remove the cuttings immediately rather than leave them lying. "Weeds" is defined in § 731-1-W to include any unmanaged vegetation, expressly naming honeysuckle, that exceeds the chapter's height limits, while "turf grass" under § 731-1-T means ordinary lawn grass whether alive or dead.

Once a property is designated an Abandoned Property, § 731-3(b) tightens the limit to 6 inches. A first violation is an "Initial Violation" under § 731-1-I; if it isn't abated, every subsequent citation on that property counts as a "Subsequent Violation" under § 731-1-S, and § 731-3(c) makes each additional day of noncompliance a separate offense, counted separately for every distinct plot an owner controls. There's a carve-out in § 731-4 for "Managed Natural Landscaping", designed, self-sustaining plant communities serving purposes like wildlife habitat or stormwater control, on privately owned, occupied residential property, provided the landscaped area sits back at least 3 feet from property lines, roads, alleys and driveways (or is fully fenced), and any strip between sidewalk and street stays under 10 inches except for trees.

1, give the director of buildings and inspections independent authority to order an unenclosed vacant lot fenced if its condition is judged a nuisance, with 20 days to comply before the city can fence it itself and bill the owner.
