Handyman License Requirements in Watertown, SD

By Ray Duke, Founder of Bulletproof Handyman · Last reviewed July 2026

Handymen and small contractors in Watertown, South Dakota are not required to hold a state-issued general contractor license, but must obtain a South Dakota Contractor's Excise Tax License from the Department of Revenue (free application; 2% excise tax on gross receipts) and a Residential or Commercial Contractor License from the City of Watertown. Trade-specific work (electrical, plumbing) requires separate state licensure. South Dakota has no formal dollar-threshold handyman exemption; however, property owners performing work on their own residence are generally exempt from licensing requirements. All contractors must verify local permit requirements with Watertown's Community Development Office.

State Contractor Licensing Law (SD)

The owner-exemption applies ONLY to the property owner doing work on their own residence—not to hired handymen. Hired contractors must obtain the state Contractor's Excise Tax License even for small jobs. Trade-specific licenses (electrical, plumbing) are required separately and are NOT covered by any exemption. Permits may still be required for certain work even if licensing is not.

Permit vs. Contractor License — The Legal Difference

A LICENSE is permission to perform a trade or occupation (e.g., electrician license, plumber license, contractor license). A PERMIT is authorization to perform a specific project at a specific location (e.g., building permit, electrical permit, plumbing permit). You can hold a valid license but still need a permit for each job. Even if you are exempt from licensing (e.g., as a property owner), you may still be required to obtain permits for certain work. Permits ensure that work meets building codes and safety standards. In Watertown, the City of Watertown issues both contractor licenses and project-specific permits through the OpenGov online system.
