For the purpose of enforcing the zoning regulations, the board of county commissioners may provide for a system of zoning certificates, and for this purpose may establish and fill the position of county zoning inspector, together with such assistants as the board considers necessary, fix the compensation for such positions, and make disbursements for them. In any county in which a county building inspector has been appointed in accordance with section 307.38 of the Revised Code, the board of county commissioners may designate such official to serve, in addition, as the county zoning inspector for the purposes of sections 303.01 to 303.25 of the Revised Code.
