Who Needs a Contractor License in Wisconsin?

Wisconsin's contractor licensing is managed by the Department of Safety and Professional Services (DSPS). The primary credential for residential work is the Dwelling Contractor Qualifier (DCQ), which is required for anyone who contracts to perform structural, insulation, or weatherization work on one- and two-family dwellings. The DCQ requires passing an exam and costs $60 for initial certification with $60 biennial renewals. In addition to the DCQ, specific trade licenses are required for electrical work (Master Electrician or Journeyman Electrician), plumbing (Master Plumber or Journeyman Plumber), and HVAC work (HVAC Qualifier). Commercial building work has separate requirements and is regulated under the Commercial Building Code (SPS 361–366). Many municipalities also require contractor registration at the local level, which is separate from state licensing. Homeowners are exempt from contractor licensing requirements when performing work on their own owner-occupied single-family home. You can pull your own permits and do the work yourself, but you must still meet all code requirements and pass inspections. This exemption does not extend to rental properties, investment properties, or properties you intend to sell immediately after completion. Hiring an unlicensed contractor exposes you to liability for code violations and may void your insurance coverage.
