Treated posts sitting on concrete or metal standoffs, so the wood isn't in
direct ground contact. You do need to tie it down so it doesn't blow away.
Mobile home anchors, or if you want to get fancy, have a welder make some
square-section tubes to slip the legs into, with big augers like used for
huge dog tiedowns attached to them (or even just bigass metal stakes), and
holes for horizontal bolts through the uprights. Or, like the other guy
said, just plant the posts like fenceposts or mailbox posts, cut the tops
off even, and frame it up from there. I don't think things without solid
roofs and/or panels (like sheds or fences) are considered 'structures' in
most areas. Drive around the neighborhood, and see what the neighbors have
put up- you can probably get away with the same.
