Solar Permit rules nationwide, beyond Wisconsin.
Requirements and size thresholds for solar permits vary by locality. The table below compares what each Wisconsin county or city requires. Always confirm with the local office before starting.
Comparing states? See solar permit rules across every locality we cover.
The application steps and inspection sequence for solar 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 solar 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 Wisconsin Department of Safety and Professional Services (DSPS) license active, and under which business name? Verify it on license.wi.gov.
