Ohio Rev. Code § 5126.026
Except as otherwise provided in this section and section 5126.0218 of the Revised Code, a member of a county board of developmental disabilities may be reappointed to the county board. Prior to making a reappointment, the appointing authority shall ascertain, through written communication with the board, that the member being considered for reappointment meets the requirements of sections 5126.022 and 5126.0218 of the Revised Code.
A member who has served during each of three consecutive terms shall not be reappointed for a subsequent term until two years after ceasing to be a member of the county board, except that a member who has served for ten years or less within three consecutive terms may be reappointed for a subsequent term before becoming ineligible for reappointment for two years.
If, however, a county board experiences extenuating circumstances that would severely restrict the board from being able to fill a pending vacancy of a board member who will become ineligible for service on the board after serving three consecutive terms, the appointing authority may request a waiver from the director of developmental disabilities to allow that member to serve an additional four-year term subsequent to serving three consecutive four-year terms. The director shall determine if the extenuating circumstances associated with the board warrant the granting of such a waiver.
