Contractor License Requirements in Wisconsin

Wisconsin requires contractor licensing for construction work. The licensing process is overseen by the Wisconsin Department of Safety and Professional Services (DSPS). Wisconsin requires licensing for dwelling (residential) contractors. A dwelling contractor qualifier must be designated for each contracting business. The qualifier must pass an exam. Commercial contractors are not required to hold a state license, but many municipalities have their own requirements.

Important

Never hire a contractor who cannot provide a valid license number. A legitimate contractor will have no hesitation sharing their license credentials for you to verify independently. If a contractor refuses, discourages you from checking, or makes excuses, treat that as a serious red flag.

Visit the Wisconsin Department of Safety and Professional Services (DSPS) website to verify any contractor's license before hiring.

Wisconsin does not currently have reciprocal contractor licensing agreements with other states. Contractors licensed in other states must apply for a new Wisconsin license through the standard application process. Some states may credit out-of-state experience toward licensing requirements -- contact the Wisconsin Department of Safety and Professional Services (DSPS) for details.
