The application steps and inspection sequence for plumbing permits come from the model code rather than from Wisconsin law, so they read the same wherever you build. We keep that walkthrough in one place: how a plumbing permit application and its inspections work, start to finish. What changes between Wisconsin jurisdictions is below: who requires a permit, what they charge, and which office you file with.

Hire it out
Before you sign, ask the contractor:
- Who pulls the permit, you or me, and is the permit fee included in the bid?
- Which inspections will this job need, and who meets the inspector on site?
- Is your contractor license active in this locality, and under which business name?
