Code Change Cycle Codes are updated automatically and on an ongoing basis through various citizen advisory project committees and the Wisconsin Building Code Advisory Review Board. Most recent update to COMM 63 codes effective September 1, 2011.
Commercial Code Comm 61-66 of the state-developed Uniform Dwelling Code (UDC) is mandatory statewide. It is applicable to nonresidential dwellings and incorporates the 2009 IECC including additional air barrier requirements. COMcheck can be used to show compliance.

Residential Code COMM 22 of the state-developed Uniform Dwelling Code (UDC) is applicable to 1 and 2 family dwellings and incorporates the 2006 IECC with state amendments. (REScheck may be used when the code assignment is indicated to be "Wisconsin" in REScheck). Multi-family dwellings also comply with these codes in addition to specific changes from the 2009 IECC implemented on September 1, 2011.

In March 2006, SB 459 was enacted to promote renewable energy and update the state's building energy codes.

The law required the Department of Commerce (DOC) to create codes for energy conservation in public buildings and places of employment and to review that code. In conducting the review, the DOC must consider incorporating into the Energy Conservation Code design requirements from the most current national energy efficiency design standards that are generally acceptable and used by engineers and the construction industry. Unlike the previous law, SB 459 refers to the International Energy Conservation Code instead of the 1989 version of a standard adopted by ASHRAE. The bill also changes the five-year revision requirement to a three-year requirement.

The state of Wisconsin implemented many changes to its Uniform Dwelling Code (UDC) for 1&2-family dwellings. Among them, changes were made to COMM 22 (beginning on page 66/102) of the UDC to incorporate the 2006 IECC with Wisconsin amendments. The 2009 IECC code, with some augmentations for commercial construction was officially implemented on September 1, 2011.
