A nephew of mine in Minnesota started landing at his farm a year or so ago, built a pole barn for the plane, and to my knowlege hasn't even asked the county for 'permission'. - Why would you?
Unless your landing/takeoff headings, -- and the noise, - would bother your neighbors, why should anyone else care? -- Check with them, then do it..
The county has a process set up for this activity. I'm not sure exactly how they get authority over this, or wether it would stand constitutional muster, but I don't have the resources to fight it.
