Is there a precidented case where someone never left their own property and recieved a dui without some kind of harm inflicted to others?

You didn't give much by way of facts. 

Some states restrict the offense of DUI to public property but most states make it unlawful to be DUI on private property.  If Minnesota is one of the latter states then even though you were on private property, if you were in physical control and had access to any public street, you can be charged with a DUI.  The reasoning - you had to drive to that location, or were going to leave to get to another.

However, an experienced DUI attorney in your area can help you fight this.  Drunk driving offenses comprise a highly technical area of the law and are fact specific.  Your attorney may well be successful in getting the charges dismissed or at least reduced.  Since a DUI triggers both a civil and criminal case,  it's always worth fighting.
