(a) General. Where, in any specific case, different sections of the Ohio Building Code specify different materials, methods of construction or other requirements, the most restrictive shall govern. Where there is a conflict between a general requirement and a specific requirement, the specific requirement shall be applicable.
(b) Other Laws. The provisions of the Ohio Building Code shall not be deemed to nullify any provisions of state or federal law. The Municipality, under Section 3781.01 of the Ohio Revised Code, may make further and additional regulations, not in conflict with Chapters 3781 and 3791 of the Ohio Revised Code or with the rules of the Board of Building Standards. However, under Section 3781.12 of the Ohio Revised Code, approval by the Board of Building Standards of any fixture, device, material, system, assembly or product of a manufacturing process, or method or manner of construction or installation shall constitute approval for their use anywhere in Ohio. The rules of the Board of Building Standards shall supersede and govern any order, standard, or rule of the Division of the Fire Marshal or Industrial Compliance in the Department of Commerce, and Department of Health and of counties and townships, in all cases where such orders, standards or rules are in conflict with the rules of the Board of Building Standards, except that rules adopted and orders issued by the Fire Marshal pursuant to Chapter 3743, of the Ohio Revised Code prevail in the event of a conflict.
