The requirements below come from Michigan rules and describe the standard the work must still meet. They are not a statement that Unincorporated Ontonagon County will issue you a permit.
Most likely yes. Window or exterior door replacement usually requires a permit in Michigan. Confirm the specifics with Unincorporated Ontonagon County.
Enlarging an opening, moving it, or cutting a new one is structural work. Exemptions that cover replacing a unit in its existing opening do not reach it, so a permit is required. Changing an opening usually means a new or resized header, and many jurisdictions want a beam detail or engineering before they will issue, so allow for that in the schedule. Window and door replacement is not on Michigan's list of work exempt from permit (R 408.30505); only work the enforcing agency accepts as an ordinary repair is exempt under MCL 125.1510(7). Cutting or enlarging openings, changing headers, or changing a required emergency escape opening goes beyond ordinary repair and needs a permit. Replacement windows and doors must meet the residential energy provisions of the Michigan Residential Code; glass-only replacement in an existing sash and frame is exempt from those provisions.
