Wisconsin Contractor License Exam Guide (2026)

How Wisconsin licenses contractors

DSPS licenses Dwelling Contractors (company) and Dwelling Contractor Qualifiers (individual). Plumbing, electrical, and HVAC-refrigeration trades require separate DSPS credentials. City permits (Milwaukee, Madison) may require additional bonding.

Expect minus-thirty wind chill, 70-psf snow, and expansive silty clay. Exams highlight frost heave protection, radon cold-climate details, and stormwater plan submittals.
