Code Adoption and Change Process

Code Change Process

Regulatory and Legislative: The code is adopted by the Department of Commerce after a code development and public hearing process. The state code provisions are first developed within the Department of Safety and Professional Services. Modifications to the code are developed in accordance with Chapter 227 of the Wisconsin Statutes. As of 2011, all UDC update proposals that add more than $1,000 in additional building costs must go through the full legislative process. Previously, all updates went through a regulatory process culminating in an administrative rule review conducted by a legislative committee.

Code Change Cycle

Codes are updated on an ongoing basis through various citizen advisory project committees and the Wisconsin Building Code Advisory Review Board.

Next Code Update

The Wisconsin Department of Safety and Professional Services is in the process of evaluating energy code updates for adoption.
