Summary
Hamilton County sets no countywide grass-height limit. Townships may cut nuisance vegetation under ORC 505.87; within municipalities, ORC 731.51 lets the city notice owners to cut noxious weeds within five days, and local codes set the actual height limit.
Upon written information that noxious weeds are growing on lands in a municipal corporation, and are about to spread or mature seeds, the legislative authority shall cause a written notice to be served upon the owner, lessee, agent, or tenant having charge of such land, notifying him that noxious weeds are growing on such lands and that they must be cut and destroyed within five days after the service of such notice.
Full Breakdown
Ohio does not fix a statewide lawn height; the limit (often 8-12 inches) comes from your city, village, or township ordinance. In municipalities, ORC 731.51 requires the legislative authority, on written information that noxious weeds are growing and about to spread or seed, to serve the owner written notice to cut and destroy them within five days. In unincorporated townships, ORC 505.87 lets trustees abate nuisance vegetation after notice and assess the cost to the owner's taxes. Enforcement is complaint-driven. Because Hamilton County is heavily incorporated, most residents are governed by a city weed/grass ordinance rather than any county rule.
Violations & Fines
If the owner fails to cut, the municipality or township cuts the vegetation and certifies the cost to the county auditor as a tax assessment/lien.
