I would think that if your mobile dwelling was small enough, building a roofed pole structure would be a benefit (shade, dry area to work on vehicle). Slowly closing in the pole structure one section at a time and leaving a large door in one section would make it look simply like a typical pole barn/shed. It would be easier to heat/cool your mobile dwelling. Wind would not blow all your stuff away. And when you left the barn/shed in your mobile dwelling, you could leave things like lawn chairs there with out worrying about any strong storms relocating them to the neighbours yard (or beyond). I would love to be able to slide the bus into a pole barn. I could clean and recoat the roof. Do much of my repair work out of the blazing hot sun or dripping rain. No one would know I was working on my bus because they would not see it. I could set the sections to where the ones (doors) opposite a bus window could be open or screened. To me, it's a win-win all around. If I so choose, I can put solar panels (not likely) or a solar batch water heater (more likely) on the roof. I could tuck a small guest apartment in the barn/shed for guests or income (not likely). Does mean getting a building permit. I've gotten a lot of those before. But that is why I would rather have a structure already on the property. No building permit if I just "fix a few things". NOT RENOVATE! NOT REMODEL! You need to watch your words. Just fix up a room at a time. You don't need a building permit to add a little trim moulding, fix a hole in the wall, add a door or paint. In some places you might need a permit to re-roof though. You most likely need a permit to ADD a bathroom but not to replace the toilet. If you aren't ADDING to a structure, you can usually get around a permit. I have seen people put a singlewide mobile home on a piece of land. Then put a freestanding roof over the trailer. Add a porch. Enclose the porch. Add another porch. Enclose the porch. One day the trailer gets pulled out and the space the trailer took up gets floor joists put in and finished up. No permit. My parents did that (took a couple of decades too). Lots of folks I know in rural NC did that. Keep your mouth shut, buy in small amounts, don't use the lumber yards delivery, do it over years not months. But some folks either can't or won't do that. They think it's "cheating. But what they either don't or won't understand is the permit for the trailer was already purchased with the trailer set. I prefer to get a pole barn or existing small house. Despite what the naysayers here and elsewhere say, I know what I can do. I know where I can buy. I have been looking at locations for a long time. The locations I am interested in are not places others tend to want to be. And that is the key. I just need a little money. The right place will come along at the right time.
