And zoning has nothing to do with this. That's for buildings and types of businesses.
So a roach coach isn't a "building" type structure on wheels (even though the IRS will even tax a lean-to on your property) and it isn't a "business".
Around here you’d be amazed at what they’ve done with zoning and permits.
Coke has a deal with the city were no vendors with non-coke products can get a permit to sell drinks at special events - except the event sponsors.
Cash cow for the city.
