Wisconsin does not issue a general contractor license at the state level the way California or Oregon do. For most residential new construction the relevant credential is the Dwelling Contractor Certification, and for trade work the relevant credential is a DSPS-issued individual trade license (electrician, plumber, HVAC). Local municipalities may also require a contractor registration on top. Dwelling Contractor Certification. Required for any person or business that contracts with an owner to build or substantially alter a 1 or 2 family dwelling. Issued by the Department of Safety and Professional Services (DSPS). Two flavors: - Dwelling Contractor Certification. The business certification. - Dwelling Contractor Qualifier Certification. The individual certification held by the person who completes the required continuing education. A business must either have a qualifier on staff or engage one as an employee. DSPS trade credentials. Separate from the Dwelling Contractor program. - Electrical. Journeyman Electrician, Master Electrician, Residential Master Electrician, Electrical Contractor registration. - Plumbing. Journeyman Plumber, Master Plumber, Utility Contractor. - HVAC. HVAC qualifier credentials apply for work performed under Wisconsin Uniform Dwelling Code. To operate as a trade contractor in Wisconsin you generally need: 1. The individual trade license for the work (electrical, plumbing, HVAC). 2. A DSPS electrical or plumbing contractor registration if you hold yourself out as a contractor in that trade. 3. The Dwelling Contractor Certification if you contract for residential new construction or substantial alterations. 4. Business entity registration with the Wisconsin Department of Financial Institutions (DFI) if you operate as an LLC, corporation, or registered partnership. 5. A seller's permit from the Wisconsin Department of Revenue if you sell taxable goods. 6. Any local municipal contractor registration the city or town requires. Commercial work covered by the Wisconsin Commercial Building Code is separately permitted and plan-reviewed through DSPS. Check the DSPS credential finder linked below for the specific credential a project requires before you bid. Requirements for hour counts, examinations, and continuing education change periodically.
