Do I need a permit for solar panel installation in Unincorporated Rock County?

Unincorporated Rock County does not issue residential building permits. Rock County is not on the DSPS list of counties delegated to enforce the Uniform Dwelling Code, so the county issues no residential building (UDC) permit. Every Wisconsin town, village and city is covered by the state UDC: a town with its own delegated UDC program issues the permit itself; in a town without one, the DSPS permitting map directs homeowners to the Wisconsin Department of Safety and Professional Services (DSPS) (608-261-6541).

The requirements below come from Wisconsin rules and describe the standard the work must still meet. They are not a statement that Unincorporated Rock County will issue you a permit.
