Searches require warrants. The fourth has specific criteria, requiring specific location and people or items. A geofence fails that criteria because it doesn't say who is to be searched, it also has an overly broad place. An address explicitly listing buildings is half of appropriate criteria, a city block is not. A 2 mile radius is not. The other half is the specific people or items.
