What Can a Handyman Do Without a License in Watertown, Codington County, South Dakota?

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.
