1. South Dakota Plumbing Commission - Plumbing Contractor License

   Plumbing contractors in South Dakota must hold a Plumbing Contractor License from the SD Plumbing Commission (Department of Labor and Regulation, 605-773-3429). South Dakota does not use a 'Master Plumber' designation - the license tiers are Plumbing Contractor, Plumber, and Third-year Apprentice Plumber. A plumbing contractor's license requires six years of experience as a plumbing contractor, plumber, or plumber's apprentice (at least two of them as a contractor or plumber) at a minimum of 1,900 hours per year, plus passing the state exam. Licensure is also available by reciprocity with proof of license by exam and four hours of continuing education.

2. No Sioux Falls General Business License Required

   Sioux Falls has no general business license, and business licensing is not handled by the Finance Department. The Licensing Office operates under the City Attorney's Office and states that 'not all businesses and professions need City licensing'; Code of Ordinances Sec. 110.026 lists the complete set of licenses the city issues. Licensing is split across departments: City Attorney's Office (alcohol, medical cannabis, pawnbroker and secondhand dealers, transportation services, circus, fortune telling, motion picture theater, livery, charitable/educational/religious registration), City Clerk (raffle and bingo), Police Records (alarm businesses, peddler/mobile food), Planning and Building Services (contractor licensing), Landfill (hauler license), Water Reclamation (liquid waste generators), and the Sioux Falls Health Department (daycare, tattoo artist and establishment). Massage therapists are licensed by the state Board of Massage Therapy. If your business type is not on that list, no city license is required.
