The MN Department of Labor and Industry (DOLI) issues building, electrical, and plumbing and many other trade contractor licenses. Minnesota law requires that most residential building contractors, re-modelers, roofers and manufactured home installers obtain state licenses. To verify DOLI licensing, visit Minnesota Department of Labor and Industry.
