South Dakota uses a narrow state model. Two construction trades are licensed at the state level, both through boards within the Department of Labor and Regulation (DLR): 1. South Dakota Electrical Commission licenses individual electricians and electrical contractors under South Dakota Codified Laws (SDCL) Chapter 36-16 (Electricians). Source: SD Electrical Commission (https://dlr.sd.gov/bdcomm/electrical/default.aspx). 2. South Dakota Plumbing Commission licenses individual plumbers and plumbing contractors under SDCL Chapter 36-25 (Plumbers). Source: SD Plumbing Commission (https://dlr.sd.gov/bdcomm/plumbing/default.aspx). Trades not state-licensed. - HVAC / mechanical. No statewide HVAC license. Regulated at the municipal level (Sioux Falls, Rapid City, Aberdeen, Brookings, Watertown, Mitchell, Pierre) plus federal EPA Section 608. Fuel-gas piping may fall within SD Plumbing Commission scope. - General construction. No statewide general contractor license. The state-level compliance requirement is the Contractor's Excise Tax license (SDCL 10-46A) with the Department of Revenue, not a trade license. Some cities require general contractor registration inside city limits. Electrical license classes (state). - Apprentice Electrician: registered apprentice under supervision. - Residential Electrician: limited to one- and two-family dwellings. - Journeyman Electrician: 8,000 hours registered apprentice experience plus exam. - Master Electrician: additional hours as Journeyman plus Master exam. - Contractor Electrician (firm): required to contract for electrical work. Must have a Master of record. - Electrical Inspector: separate credential for code-enforcement work. Plumbing license classes (state). - Apprentice Plumber: registered apprentice under supervision. - Journeyman Plumber: 8,000 hours registered apprentice experience plus exam. - Master Plumber: additional hours as Journeyman plus Master exam. - Contractor Plumber (firm): must hold a Master of record. - Restricted Appliance, Sewer and Water, Underground Irrigation: narrower specialty classifications with limited scope. Bonding. No statewide trade-license bond applies at either commission. Public works projects require payment and performance bonds under SDCL Title 5. Municipal mechanical and plumbing registrations in some cities carry small bonds. Renewal and CE. Electrician and plumber licenses renew annually. Both commissions require approved continuing education each renewal (NEC update for electrical; plumbing-code update for plumbing). Verify current hour counts on the commission CE pages. Reciprocity. Both commissions have reciprocity agreements with neighboring states under SDCL and rule. Verify the current reciprocity list on the commission's licensing page. Unlicensed contracting. Performing electrical work requiring an SD Electrical Commission credential, without holding it, is a violation under SDCL 36-16. Performing plumbing work requiring an SD Plumbing Commission credential, without holding it, is a violation under SDCL 36-25. Both can result in civil penalties and referral for criminal charges in serious cases. Municipal mechanical and general-contractor enforcement operates at the city level.
