Wisconsin WI Plumbing License Requirements and Plumber License Verification, Renewal and Application

Wisconsin Department of Safety and Professional Service (DSPS) are the ones who you must apply with to become a licensed Plumbing Contractor or Journeyman Plumber in Wisconsin. There are many laws, rules, and regulations covering the various professions, industry services, and petroleum products and petroleum storage tanks for which the Department of Safety and Professional Service (DSPS) has responsibility. These laws, rules, and regulations come from actions of the Legislative and Executive Branches which pass laws that modify Wisconsin Statutes and the Rulemaking process which involves agencies such as DSPS working together with professional boards to develop rules which will carry out requirements set out in Wisconsin Statutes. These rules, when they are developed and finalized, become part of the Wisconsin Administrative Code. More information on each of these topics can be found by following the links below.(excerpt from Department of Safety and Professional Service (DSPS) official website).
