Before the promulgation of an amendment to the code, the boards whose functions relate to that code may draft and recommend to the director proposed language. The director shall consider all submissions by the boards. However, the director has final responsibility for the promulgation of the code.

    (5) The director shall add, amend, and rescind rules to update the Michigan building code, the Michigan mechanical code, the Michigan plumbing code, the Michigan rehabilitation code for existing buildings, the Michigan electrical code, and the commercial chapters of the Michigan energy code not less than once every 3 years to coincide with the national code change cycle.

    (6) Within 90 days after the effective date of the 2012 act that amended this section, the director shall begin the process to add, amend, or rescind rules to update the 2009 Michigan residential code, including the residential energy code chapter. Commencing with the 2015 national code change cycle, the director shall add, amend, and rescind rules to simultaneously update all chapters of the Michigan residential code not less frequently than once every 6 years or more frequently than once every 3 years as the director determines is appropriate. Not more than 200 days after the printed publication of the latest edition of the international residential code book is made available to the general public, the director shall hold a public meeting in Lansing and offer persons an opportunity to present data and comments on the general need to update the Michigan residential code.

The department shall post notice of the determination on its website for at least 45 days.

    (7) If the director makes the determination not to update the Michigan residential code, a person may, within 45 days after the determination, request the director to promulgate a rule to amend a section or sections of the Michigan residential code. Within 90 days after the filing of a request, the director shall initiate the processing of a rule or shall issue to the requestor a concise written statement of the principal reasons for denial of the request and post the denial statement on the department's website until the Michigan residential code is next updated. The denial of the request is not subject to judicial review.

    (8) Before the Michigan building code, the Michigan residential code, the Michigan plumbing code, the Michigan mechanical code, the Michigan uniform energy code, and the Michigan rehabilitation code may be enforced, the director shall make each Michigan-specific code available to the general public for at least 45 days in printed, electronic, or other form that does not require the user to purchase additional documents or data in any form in order to have an updated complete version of each specific code, excluding other referenced standards within each code. This subsection does not apply to any code effective before April 1, 2005.
