Ohio Rev. Code § 731.231
The legislative authority of a municipality may adopt standard ordinances and codes, prepared and promulgated by the state, or any department, board, or other agency thereof or any code prepared and promulgated by a public or private organization which publishes a model or standard code, including but not limited to codes and regulations pertaining to fire, fire hazards, fire prevention, plumbing code, electrical code, building code, refrigeration machinery code, piping code, boiler code, heating code, or air conditioning code, by incorporation by reference.
The publication required by sections 731.21 to 731.24 , inclusive, of the Revised Code, shall clearly identify such code, shall state the purpose of the code, shall state that a complete copy of such code is on file with the clerk of the legislative authority for inspection by the public and also on file in the law library of the county or counties in which the municipality is located and that said clerk has copies available for distribution to the public at cost. If the adopting municipality amends or deletes any provisions of such code, the publication shall contain a brief summary of such deletion or amendment.
If the agency which originally promulgated or published the code thereafter amends said code, any municipality which has adopted a code by the provisions of this section may adopt such amendment or change by incorporation by reference in an amending ordinance by the same procedure as required for the adoption of the original code without the necessity of setting forth in full in the amending ordinance the provisions of the original ordinance or code.
Ordinances or codes adopted by a municipality under the provisions of this section shall be deemed to be a full and complete compliance with sections 731.21 to 731.25, inclusive, of the Revised Code, and no other publication is necessary.
