I have worked in Minnesota and North Dakota as a certified siding installer for 15 years and have just recently decided to go out on my own with the purchase of a seamless gutter machine. We also do all aspects of residential exterior work as well.
Licenses are required for all residential building contractors Minnesota who contract with a owner of "residential real estate" to construct or improve dwellings by provinding work in more than one special skill
Permits on electrical works on their own property can be requested by homeowners through the page https://ims.dli.mn.gov/ims
Contractors who have a state license don't need to obtain a local license for work that is covered under the state licensing laws.
