unimproved land definition

I have roughly 3 acres in the mountains. I have drilled a water well, put in septic system and electricity as well as driveways. I do plan on building at some time in the future. I have a motorhome on the property with deck and other amenities. I have been informed that I cannot "camp" on the property longer than 6 months each year. I have also been informed that a "camper" cannot be left on "unimproved" property over 6 months each year. "Campers" can be left on properties with homes. Since I have added utilities and am not "camping" do I have any basis to contest this? From what I can determine, the addition of the well, sewer, driveway, electrical service and septic makez this an improved parcel. In fact, the county increased the valuation due to "the improvements". THANKS.
