Code Adoption and Change Process

Code Change Process

The Michigan Uniform Energy Code (MUEC) is promulgated by the Department of Licensing and Regulatory Affairs (LARA, formerly DELEG) Bureau of Construction Codes and is evaluated for revisions or modifications every three years.

Code Change Cycle

The Bureau of Construction Codes in the Department of Licensing and Regulatory Affairs (LARA, formerly DELEG) reviews the MUEC every three years in concurrence with the national model code cycle. Section 1972 PA 230 states that the director of the construction code commission shall add, amend, and rescind rules to update the commercial chapters of the Michigan energy code not less than once every three years to coincide with the national code change cycle. However, this document also states that, 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 six years or more frequently than once every three years as the director determines is appropriate. This code change cycle process was enacted by House Bill No. 4561 in 2012.

Next Code Update

According to the 2015-2016 rules status chart, the new commercial energy code will be effective by early 2017.

The October 1st Michigan Register gives notice that the state is updating its commercial energy code to be based on the 2015 IECC and ASHRAE 90.1-2013 with amendments.

The Department of Labor and Economic Growth (DELEG) establishes a committee to review and update Michigan’s Uniform Energy Code. After review and promulgation of the code, the Ingham County Circuit Court issued an injunction to halt the February 28, 2005 effective date of the rules in response to a lawsuit by the Michigan Association of Home Builders (MAHB). The new code was not implemented between 2005 and 2008 while litigation was before the courts.

On October 24, 2008, the judge presiding over the litigation dismissed the MAHB complaint and dissolved the lawsuit, making the rules effective immediately. Therefore, every unit of government enforcing the single state construction code had to apply the 2003 Michigan Uniform Energy Code to newly issued permits.
