In most Michigan jurisdictions, yes. Running electrical to an outbuilding typically requires a permit and an inspection by a licensed electrician. This is separate from any permit for the building itself. Even if your shed didn't need a permit, the electrical work probably does.
This protects you. Improper wiring in an outbuilding is a fire risk and can affect your homeowner's insurance. Have a licensed electrician pull the permit and do the work. It's one of those things worth doing right.
