Ohio Rev. Code § 961.02
The owner of any land used or to be used as a pet cemetery shall file, or cause to be filed, in the office of the county recorder of the county in which the land is located, a declaration restricting the land to being used only for such purposes as are usual and normal for the operation of a pet cemetery. The owner shall execute the declaration in the same manner and with the same effect as a conveyance of an interest in land. The county recorder shall record the declaration in the official records. The restriction established in such a recorded declaration may be removed only as provided in section 961.05 of the Revised Code. Unless a restriction is so removed, no person shall use land restricted as provided in this section for any purpose other than for pet cemetery purposes.
