Green Lake County Plumbing Permit Requirements
Plumbing work in Green Lake County, Wisconsin, must comply with the Wisconsin State Plumbing Code. Permits are required for all plumbing work, and these permits can only be issued to licensed plumbers. However, an owner occupying a single-family residence may perform plumbing work themselves without a license, provided they obtain a permit and ensure the work meets all code requirements. Any person assisting such an owner must be a licensed master plumber.

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.
