Wisconsin Plumbing Legislation, Codes, and Guidelines

Wisconsin Plumbing Code and Legislation

Wisconsin maintains its own unique, state-specific plumbing code rather than adopting the International Plumbing Code (IPC) or Uniform Plumbing Code (UPC). The state's plumbing regulations are codified in the Wisconsin Administrative Code, specifically Chapters SPS 381 through SPS 387. These chapters establish the statewide standards for the design, construction, installation, supervision, maintenance, and inspection of plumbing systems.

The primary state agency responsible for setting and administering these standards is the Wisconsin Department of Safety and Professional Services (DSPS). The DSPS Plumbing Division oversees plumbing licensure, code adoption, product approvals, and industry oversight. The authority for these regulations is derived from Chapter 145 of the Wisconsin Statutes, which mandates the regulation of plumbing practices to protect public health and safety.
