Trade business resources for Minnesota.

In Minnesota, trade contractor licensing is administered primarily by the Department of Labor and Industry (DLI), which oversees licensing for electricians, plumbers, HVAC contractors, and residential builders. There is no single general contractor license for commercial work, but contractors performing residential construction must be licensed as Residential Building Contractors or Residential Remodelers through the DLI.

State licensing board

Minnesota requires separate licenses by trade: Electrical contractors and individuals must be licensed through the DLI's electrical licensing program, with journeyworker and master electrician classifications. Plumbers must hold a master plumber license to contract plumbing work, and plumbing contractors must also be licensed through DLI. HVAC contractors performing mechanical work on residential or commercial buildings must hold a Refrigeration/Heating and Air Conditioning contractor license through DLI. For general residential construction, any contractor who contracts directly with a homeowner for new residential construction or remodeling must be licensed as a Residential Building Contractor (for projects over $15,000) or Residential Remodeler; projects under $15,000 may fall under a Residential Roofer license for roofing-specific work. There is no statewide commercial general contractor license requirement, though municipalities may impose local requirements. All licensed contractors must maintain required bonds and insurance as a condition of licensure.
