Purchase Wisconsin Codes

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.
