As stated in Regulation .02B of this chapter, the Model Performance Code is not binding on any subdivision of the State unless specifically adopted by it. A copy of the law, ordinance, or resolution adopting the Model Code shall be sent by the governing body of the adopting subdivision to the Secretary. Copies of all subsequent laws, ordinances, or resolutions pertaining to the Model Code shall similarly be sent by the governing body to the Secretary. After adoption by a subdivision, alteration or modification of the Model Code is prohibited without prior concurrence of the Secretary. The Department will regularly consult with local officials to review the application and effectiveness of the Model Code in each adopting subdivision. Requests for Changes. Requests for changes, modifications, or exceptions to make the Model Code more effective and useful in any subdivision shall be submitted in writing by certified mail, return receipt requested, to the Secretary by the appropriate authority in the subdivision, together with the reasons for the request. Upon receipt of a request, the Secretary may: Concur with it; Take no action for a period of 30 days after receipt of the request, which shall be deemed concurrence; or Deny the request and notify the requesting subdivision in writing. The Secretary may utilize the 30-day period provided hereby for informal consultation with the requesting subdivision and with any other individuals or groups. Concurrence with requests for special Model Code provisions to meet local conditions will not be unreasonably withheld. The administrative sections of Article 1 of the International Building Code are entirely administrative and may require alteration to adapt them to local use. Alterations to these sections of Article 1 are therefore excluded from the requirement of concurrence by the Secretary. However, any alterations shall be forwarded to the Secretary for the Department’s records.
