Low-voltage licensing
South Dakota
South Dakota requires Electrical Contractor licensing through the State Electrical Commission. Class A (full) and Class B (residential) Electrical Contractor classifications cover low-voltage scope. Master and journeyman electrician credentials are separate from the contractor business license.

Common pitfalls
Mistakes we see installers make when navigating South Dakota licensing.
- Class B is residential-only; doing commercial work under a Class B license invalidates that license for the commercial job.
- Master Electrician can only qualify ONE contractor business at a time.
- Annual renewal; license expires June 30 statewide regardless of issue date.
