Ohio Rev. Code § 505.373
The board of township trustees may, by resolution, adopt by incorporation by reference a standard code pertaining to fire, fire hazards, and fire prevention prepared and promulgated by the state or any department, board, or other agency of the state, or any such code prepared and promulgated by a public or private organization that publishes a model or standard code.
After the adoption of the code by the board, a notice clearly identifying the code, stating the purpose of the code, and stating that a complete copy of the code is on file with the township fiscal officer for inspection by the public and also on file in the law library of the county in which the township is located and that the fiscal officer has copies available for distribution to the public at cost, shall be posted by the fiscal officer in five conspicuous places in the township for thirty days before becoming effective. The notice required by this section shall also be published in a newspaper of general circulation in the township once a week for three consecutive weeks or as provided in section 7.16 of the Revised Code. If the adopting township amends or deletes any provision of the code, the notice shall contain a brief summary of the deletion or amendment.
If the agency that originally promulgated or published the code thereafter amends the code, any township that has adopted the code pursuant to this section may adopt the amendment or change by incorporation by reference in the same manner as provided for adoption of the original code.
