It comes down to how the property is zoned.
If it is not zoned "residential" you will never get an occupancy permit to live there full time.
^^^^i agree with THIS.
zoning and what the local city or town allows in a residential zoned area.
in my area you will never be allowed to live in a pole building. and i am pretty sure it's the same in all of SE WI. in my area they won't let you install a bathroom and even a floor drain in your garage unless it's zoned industrial.
one loophole in my area is as long as the house is attached to the garage you can build as big of garage as you want as long as the footprint of the house and garage doesn't exceed 30% of the square footage of the lot. there are certain building requirements to attach a garage to a house also...... there is a house on the other side of town about 1500sqft and he has a 20 car garage attached to his house and he has a 8 car garage detached from his house on a 5 ac lot..
i know by my friends by the wolf river party trailer in Fremont WI they allow you to live in a pole building.
