The first updates to Wisconsin plumbing code since 2009 will take effect on October 1, 2023, but related licensing exams will not be administered under the new code until November.
The state's Plumbing Code Advisory Committee received input from professional groups to shape these updates, which can now be found in the state administrative code.
While the new plumbing code takes effect October 1, 2023, DSPS is offering a brief grace period for related licensing exams. Exams will be administered under the old code throughout October. However, exams will be administered under the updated code starting in November.

***Please note printed code can be brought into the exam if it is bound together in a 3-ring binder ***
