The rule may include provisions regarding building construction, renovation, and all other aspects as related to the construction and mechanical operations of a structure. The rule shall include building energy codes. The rules shall be in accordance with standard safe practices so embodied in widely recognized standards of good practice for building construction and all aspects related thereto and have force and effect in those counties and municipalities adopting the State Building Code: Provided, That each county or municipality may adopt the code to the extent that it is only prospective and not retroactive in its application; Provided, however, That buildings or structures utilized primarily for agricultural purposes shall be exempt from the provisions of the State Building Code, the State Fire Code, and any county or municipal building code or ordinance that is or may be adopted, such as the ICC International Property Maintenance Code.

(c) For the purpose of this section, the term "building code" is intended to include all aspects of safe building construction and mechanical operations and all safety aspects related thereto. Whenever any other state law, county, or municipal ordinance, or regulation of any agency thereof is more stringent or imposes a higher standard than is required by the State Building Code, the provisions of the state law, county or municipal ordinance, or regulation of any agency thereof governs if they are not inconsistent with the laws of West Virginia and are not contrary to recognized standards and good engineering practices.

Also, any county or municipality may enter into an agreement with any other county or municipality to provide inspection and enforcement services: Provided, That any county or municipality may adopt the State Building Code with or without adopting the BOCA National Property Maintenance Code. If a county adopts a property maintenance code or ordinance including, but not limited to, the ICC International Property Maintenance Code, such code or ordinance shall exempt all property used for agricultural purposes or otherwise cause such property to be exempted from any such code or ordinance from enforcement. Any such code that may be or is adopted by any county shall be and is unenforceable as to agricultural property.
(e) After the State Fire Commission has promulgated rules as provided in this section, each county or municipality intending to adopt the State Building Code shall notify the State Fire Marshal of its adoption.
(f) The State Fire Commission may conduct public meetings in each county or municipality adopting the State Building Code to explain the provisions of the rules.
(g) The provisions of the State Building Code relating to the construction, repair, alteration, restoration, and movement of structures are not mandatory for existing buildings and structures identified and classified by the State Register of Historic Places under the provisions of §29-1-8 of this code or the National Register of Historic Places, pursuant to 54 U.S.C. § 302101 et seq.

The final decision is vested in the State Fire Marshal. Additions constructed on a historic building are not excluded from complying with the State Building Code.
