Do you need a license to work as a plumber in South Dakota?
Yes. In South Dakota, a person may not do plumbing that needs a license on any property connected to a public water or sewer system without a license from the State Plumbing Commission. The commission licenses plumbers and plumbing contractors, among other license types, after an examination. The statute exempts plumbing on premises the person owns and occupies as a residence, plumbing on a single-family home the person is building to live in, and plumbing repair work on the person’s own property or where the person is employed. This is SDCL §§ 36-25-17, 36-25-19.
