South Dakota Plumbing Legislation, Codes, and Guidelines

State Statutes and Plumbing Codes

The state of South Dakota regulates plumbing through South Dakota Codified Law (SDCL) Chapter 36-25. Under this authority, the state has adopted the 2024 edition of the Uniform Plumbing Code (UPC) as the foundational technical standard for plumbing systems. This adoption includes state-specific amendments and rules promulgated by the state commission to govern the design, installation, and maintenance of plumbing systems, including potable water distribution, drainage, waste, and vent systems.

Primary State Agency

The primary agency responsible for setting and enforcing these standards is the South Dakota Plumbing Commission. This commission, which operates under the South Dakota Department of Labor and Regulation, is tasked with administering state laws and regulations concerning plumbing, licensing plumbing contractors and plumbers, conducting examinations, and performing inspections of plumbing installations to ensure compliance with the adopted state code.
