Ohio Rev. Code Ann. § 3781.01 – Municipal corporation may make additional regulations

(A) Chapters 3781. and 3791. of the Revised Code do not prevent the legislative authority of a municipal corporation from making further and additional regulations, not in conflict with those chapters or with the rules the board of building standards adopts. Those chapters or rules do not modify or repeal any portion of any building code adopted by a municipal corporation and in force on September 13, 1911, that is not in direct conflict with those chapters or rules.
(B) The state residential building code the board of building standards adopts pursuant to section 3781.10 of the Revised Code does not prevent a local governing authority from adopting additional regulations governing residential structures that do not conflict with the state residential building code if the procedures in division (C) of this section are followed.
(C)
1. (1) A local governing authority shall, and any person may, notify the board of building standards of any regulation the local governing authority adopts pursuant to division (B) of this section and request the board of building standards to determine whether that regulation conflicts with the state residential building code.
2. (2) Not later than sixty days after receiving a notice under division (C)(1) of this section, the board shall determine whether the regulation conflicts with the state residential building code and shall notify any person who submitted the notice and the local governing authority that adopted the regulation of the board's determination.
  1. (a) If the board determines that a conflict does not exist, the board shall take no further action with regard to the regulation. If the board determines a conflict exists and the regulation is not necessary to protect the health or safety of the persons within the local governing authority's jurisdiction, the regulation is not valid and the local governing authority may not enforce the regulation.
  2. (b) If the board determines that a conflict exists and that the regulation is necessary to protect the health or safety of the persons within the local governing authority's jurisdiction, the board shall adopt a rule to incorporate the regulation into the state residential building code. Until the rule becomes a part of the state residential building code, the board shall grant a temporary variance to the local governing authority and any similarly situated local governing authority to which the board determines the temporary variance should apply.
(D) As used in this section, "local governing authority" means a board of county commissioners, a board of township trustees, and the legislative authority of a municipal corporation.
