Easier said than done. For example Unincorporated San Diego does not require a Business License, but you need to get approval from the Sheriffs dept. That requires you find a building that is in an Industrial Zone, and 1000 feet from Schools, Residence, Church, and just about everything else, so the available properties are few and have been taken. I would imagine this is pretty standard through most counties. You could find a Blank Piece of Property out in the Middle of nowhere, but the cost for building construction, bringing water and power to the property, etc, etc, etc,, is prohibitive.
