My plan is to construct a structure for myself on a 6 by 8 trailer. I then want to park that trailer at my property but build and connect an insulated shed/outbuilding to house my freezer and battery banks. Is it likely that I would run into coding troubles? I understand I can live in the trailer's tiny house and avoid the issue but I had this idea of connecting several "cells" to form a house. I want the trailer to be a movable core wherein the outbuildings can be modified so that when the trailer is parked correctly, all I have to do is button up a thermal envelope and my tiny house suddenly has several off shooting rooms. I wonder if this would be "legal".
I am looking for land in the Northeast no lower than Pennsylvania but any New England state or NEw York is where most of my attention is.
It's an interesting idea if you can work it. Most inspectors (at least in my area) will allow living in a wheeled structure only for a time before a full house is required. You can say you are in the stages of building etc to keep them off your back for a while but in the end they will want a house, unless you can get a hold of someone who is up to speed on the small house movement and will consider it. It'll take some work.
Now if you can get a hold of some acreage where you can tuck this building out of the way and blend it in so nothing stands out, who says you have to let the inspectors know at all.
There are some interesting stuff on youtube where people take enclosed cargo trailers and revamp them into campers. Might be easier to modify but you won't be able to make those small adjustments that makes the place yours.
