South Dakota Plumber License Requirements (2026)

The South Dakota State Plumbing Commission licenses plumbers, plumbing contractors, and apprentices under SDCL Chapter 36-25. A plumber works under the direction of a plumbing contractor; a plumbing contractor is the credential that contracts for and conducts the plumbing business. State plumbing standards now substantially accord with the 2024 Uniform Plumbing Code, while municipalities may impose local plumbing regulations that meet state minimum standards.

Licensing for this trade is governed by South Dakota Department of Labor and Regulation — State Plumbing Commission (SD Plumbing Commission), the agency that issues and regulates the credential under SDCL Chapter 36-25; ARSD Article 20:53. Licenses plumbers, plumbing contractors, apprentices, and related specialty credentials; administers examinations, continuing education, and plumbing standards.

Common Filing Mistakes

These are the recurring mistakes that most often delay or reject a South Dakota Plumber application, based on the official instructions cited here.

Using the wrong statute chapter

Plumbing is governed by SDCL Chapter 36-25, not the older chapter reference.

Relying on a fixed experience claim

Use current Commission qualifications for the selected license instead of the unsourced 7,800-hour statement.

Ignoring municipal rules

Local plumbing regulation and permits may apply as long as local standards meet the state minimum.

Missing CE

Covered licenses require four annual hours, two covering code.
