Wisconsin Contractor & Trade License Requirements

Wisconsin requires a Dwelling Contractor certification for contractors building or remodeling one- and two-family dwellings, administered by the Department of Safety and Professional Services (DSPS). The state also licenses electricians, plumbers, and HVAC contractors at the state level through DSPS. There is no separate statewide general commercial contractor license or roofing license. Commercial contracting and roofing are regulated at the local level.
