Hamilton County does not regulate backyard livestock; it is a local zoning matter. On unincorporated township land, ORC 519.21 bars township zoning from prohibiting agriculture (including livestock) on most lots, but allows regulation on platted subdivision lots of one acre or less. Cities and villages set their own livestock rules.
Whether you can keep cattle, horses, goats, sheep, or hogs in Hamilton County depends on your local zoning, not a county ordinance. Ohio counties do not zone individual parcels; townships zone unincorporated land under ORC Chapter 519 and cities zone within their limits. ORC 519.21 protects agricultural use - which includes 'animal and poultry husbandry' - from township prohibition on most land, so on larger unincorporated lots livestock is broadly allowed. The statute's exception lets townships regulate agriculture on platted subdivision lots of one acre or less, and impose limited restrictions on lots between one and five acres. In incorporated areas, the city or village zoning code controls and often bars farm livestock in residential districts. Hamilton County Public Health
Zoning enforcement is local (township or municipal zoning inspector), with penalties set by that jurisdiction. Nuisance/sanitation conditions can also be cited by Hamilton County Public Health in unincorporated and contracting areas.
