South Dakota Contractor License Exam Guide (2026)

How South Dakota licenses contractors

The Department of Labor & Regulation licenses plumbers and electrical contractors statewide, while cities like Sioux Falls and Rapid City issue general-contractor licenses with ICC exams. All contractors must hold a South Dakota contractor excise tax license from the Department of Revenue.

High plains extremes swing from minus-forty blizzards to 110-degree summers. Exams highlight 60-inch frost depth, black-hills snow loads, wind exposure, and wildfire defensible space.
