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.
