International Building Code Worksheets

The Milwaukee Development Center requires that State of Wisconsin IBC worksheets be provided along with other materials required for plan submittal. There are 15 architectural worksheets, and two HVAC worksheets. Not all worksheets must be submitted for all projects. Please consult the Required Worksheets table to determine which of these forms must be submitted for each project type.

The worksheets are in PDF format (version 8.0 or higher), and may be filled in from within your web browser.

More information about the International Building Code is available on the web site of the Wisconsin Department of Commerce Safety and Buildings Division.
