Up here, if we pour a slab foundation for a shed, we need permits from the city and taxes go up. If you float the shed on a couple of 4x4's or 8x8's though you're golden, cause it's not considered a permanent structure. It a great idea, but I would did a little deeper before you break ground to make sure you`re on the up and up. God forbid something ever happens, and you have to put in an insurance claim, and they deny it cause everything wasn`t permitted and inspected.
If you can get the city on board though...oh the options are almost endless
