Ohio Rev. Code § 5709.69
If an enterprise operating in a county or municipal corporation in this state intends to relocate or relocates part or all of its operations to another county or municipal corporation in this state and has entered into or intends to enter into an agreement under section 5709.62, 5709.63, or 5709.632 of the Revised Code with that county or municipal corporation, the legislative authority or an officer of the county or municipal corporation to which the enterprise intends to relocate or relocates shall serve the legislative authority of the county or municipal corporation from which the enterprise intends to relocate or relocates with notice of the enterprise's intention to relocate, accompanied by a copy of the agreement to be entered into or entered into pursuant to section 5709.62, 5709.63, or 5709.632 of the Revised Code and a statement of the enterprise's reasons for relocation. The legislative authority or officer also shall serve such notice upon the director of development. In both cases, service shall be by personal service or certified mail, return receipt requested, not later than thirty days prior to the day of the first public meeting at which the agreement is deliberated by the legislative authority of the county or municipal corporation to which the enterprise intends to relocate or relocates. With the approval of the director of development, service shall be not later than fifteen days prior to the day of the first public meeting of the legislative authority at which the agreement is deliberated. The legislative authority or officer required to serve notice shall seek such approval by applying to the director at the earliest possible time prior to that meeting. The director may approve the later service if the director determines that earlier notice is not possible or would be likely to jeopardize realization of the project. If approval for a later notice is applied for, the legislative authority or officer need not serve notice to the director as otherwise required by this section.
If the legislative authority or officer required to serve such notices fails to do so as prescribed by this section, the legislative authority shall not enter into an agreement under those sections with that enterprise.
This section applies only to relocations of operations that result or would result in the reduction of employment or the cessation of operations at a place of business in this state.
