  1. HVAC / Mechanical Work - No State License, but a Sioux Falls City License Is Required

    South Dakota has no statewide HVAC or mechanical contractor license and no mechanical licensing board. Sioux Falls, however, does require its own license: the city's Contractor Licensing program states that a license is required of all contractors doing mechanical or HVAC work within Sioux Falls city limits (separate Fireplace Contractor and Refrigeration Contractor licenses also exist), administered by Planning and Building Services (Licensing: 605-367-8672, [email protected]). Homeowners living in and owning a single-family dwelling need not be licensed but must still permit the work. Federal EPA Section 408/608 rules apply too: anyone handling refrigerants needs EPA Section 608 certification. A separate city mechanical permit is required for each installation or major repair.

    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.
