Ohio Rev. Code § 3742 § 3742.37

(A) If the results of a risk assessment conducted under section 3742.36 of the Revised Code indicate that one or more lead hazards identified in a residential unit, child care facility, or school are contributing to a child's lead poisoning, the director of health or authorized board of health immediately shall issue an order to have each lead hazard in the property controlled. The areas of the unit, facility, or school that may be subject to the lead hazard control order include the following:
(1) The interior and exterior surfaces and all common areas of the unit, facility, or school;
(2) Every attached or unattached structure located within the same lot line as the unit, facility, or school, including garages, play equipment, and fences;
(3) The lot or land that the unit, facility, or school occupies.
(B) A lead hazard control order issued under this section shall be in writing and in the form the director shall prescribe. The director or board shall specify in the order each lead hazard to be controlled and the date by which the unit, facility, or school must pass a clearance examination demonstrating that each lead hazard has been sufficiently controlled. The director or board may include in the order a requirement that occupants of the unit, facility, or school whose health may be threatened vacate the unit, facility, or school until the unit, facility, or school passes the clearance examination.
The director or board shall have the order delivered to the owner and manager of the unit, facility, or school. If the order applies to a building in which there is more than one residential unit, the director or board shall have a copy of the order delivered to the occupants of each unit or require that the owner or manager of the building deliver a copy of the order to the occupants of each unit. If the order applies to a child care facility or school, the director or board shall have a copy of the order delivered to the parent, guardian, or custodian of each child under six years of age who receives child care or education at the facility or school or require the owner or manager of the facility or school to have a copy of the order so delivered.
