South Dakota HVAC Requirements (2026)

South Dakota does not have a standalone state HVAC trade board or state HVAC contractor license. HVAC businesses must nevertheless determine whether their work is construction services or realty improvement requiring a South Dakota contractor’s excise tax license, and must comply with the city or other local jurisdiction’s permits and trade rules. Federal refrigerant requirements are separate from state trade licensing.

Step-by-Step Compliance Roadmap

Identify the work type. Determine whether the HVAC contract includes construction services or realty improvement.
Obtain a contractor excise tax license when required. DOR says persons contracting for construction services or installing/repairing fixtures to real property need the license.
Account for the contractor excise tax. DOR states that the tax on gross receipts for construction projects is 2%, subject to the project rules.
Check the local jurisdiction. South Dakota law permits cities to regulate HVAC contractors; confirm local registration and permit rules before work.
Obtain permits and comply with local code. The absence of a state HVAC license does not eliminate local construction, mechanical, or permit requirements.
Confirm separate regulated scopes. Verify state or local licensing requirements before performing plumbing or electrical portions of an HVAC project.
Meet federal refrigerant rules when applicable. Refrigerant handling is governed separately by federal law.
