Ohio Rev. Code § 5101.651
If, during the course of an investigation conducted under section 5101.65 of the Revised Code, any person, including the adult who is the subject of the investigation, denies or obstructs access to the residence of the adult, the county department of job and family services may file a petition in court for a temporary restraining order to prevent the interference or obstruction. The court shall issue a temporary restraining order to prevent the interference or obstruction if it finds there is reasonable cause to believe that the adult is being or has been abused, neglected, or exploited and access to the person's residence has been denied or obstructed. Such a finding is prima-facie evidence that immediate and irreparable injury, loss, or damage will result, so that notice is not required. After obtaining an order restraining the obstruction of or interference with the access of the protective services representative, the representative may be accompanied to the residence by a peace officer.
