State Adoptions

The Wisconsin Department of Safety and Professional Services (DSPS), is responsible for the adoption of Wisconsin’s building, fire safety and energy efficiency codes.  They recently adopted the '15 I-Codes, effective May 1, 2018.  Although WI uses their "own" codes, they base them on the I-Codes.  Wisconsin does use their own hybrid residential code (UDC) and plumbing code.  They will remain on '09 IECC, however for residential and the ‘15 IECC for commercial.
