In Minnesota, carpentry is classified as a special skill area within the Residential Building Contractor category.

You don’t need a license if you earn less than $15,000 per year and provide only one specialty skill.
However, if you perform more than one specialty skill or earn above that threshold, you must obtain a Residential Remodeler License (for existing structures) or a Residential Building Contractor License (for new construction).
Applicants must provide proof of general liability insurance and workers’ compensation coverage, pass an exam and register their business with DLI.
