PLUMBING x SOUTH DAKOTA

Plumbing contractor requirements in South Dakota.

SDCL 36-25-17 bars anyone from doing licensed plumbing on property connected to a public waterworks or sewer system without a State Plumbing Commission license, with exemptions for an owner's own residence and for minor repair work on one's own or an employer's property. A plumber needs four years of apprenticeship at 1,900 hours a year; a plumbing contractor needs six years with at least two as a plumber or contractor, and both pass a commission exam (ARSD 20:53:03:02).

Licenses are annual and expire December 31 (SDCL 36-25-19.4). The fee rule effective July 2, 2025 sets a $50 application fee, a $100 exam fee, and annual license fees of $275 for a plumbing contractor and $105 for a plumber. Renewal requires four hours of continuing education each license period, and new contractors and plumbers complete eight hours of code training in their first year. Plumbing must meet the 2024 Uniform Plumbing Code as adopted by the commission (SDCL 36-25-15).

LICENSE TRUTH
South Dakota's State Plumbing Commission licenses plumbing contractors, plumbers, and apprentices for work on property connected to a public water or sewer system, with annual licenses expiring December 31.
STATE ↔ LOCAL
SDCL 36-25-16 lets municipalities adopt their own plumbing ordinances, inspect, and collect fees, so long as they meet the state minimum code; a state-registered plumber may work in such a city for six months after applying for its permit or license. No state plumbing permit is needed where a local permit was issued (SDCL 36-25-19.2).

What it costs to start plumbing in South Dakota.

Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.

NOTE
Annual, not biennial

Plumbing licenses expire every December 31; working 60 days or more past expiration exposes you to discipline (ARSD 20:53:12:03).

NOTE
New fee schedule

The commission's current application, exam, and license fees took effect July 2, 2025 (51 SDR 141).

NOTE
Public systems trigger the license

The SDCL 36-25-17 license requirement applies to property connected to a public water or sewer system; on-site septic work has its own installer license (SDCL 36-25-17.3).
