Ohio Rev. Code § 2933.23
A search warrant shall not be issued until there is filed with the judge or magistrate an affidavit that particularly describes the place to be searched, names or describes the person to be searched, and names or describes the property to be searched for and seized; that states substantially the offense in relation to the property and that the affiant believes and has good cause to believe that the property is concealed at the place or on the person; and that states the facts upon which the affiant's belief is based. The judge or magistrate may demand other and further evidence before issuing the warrant. If the judge or magistrate is satisfied that grounds for the issuance of the warrant exist or that there is probable cause to believe that they exist, he shall issue the warrant, identifying in it the property and naming or describing the person or place to be searched.
A search warrant issued pursuant to this chapter or Criminal Rule 41 also may contain a provision waiving the statutory precondition for nonconsensual entry, as described in division (C) of section 2933.231 of the Revised Code, if the requirements of that section are satisfied.
