Spoke with the Construction Industries Division of New Mexico. 

They are saying that a container home has to be fully designed by a structural engineer. So, another large amount of money to throw at it. I can't just "build" what I want. So, here we go again. I'm not paying to have another design engineered, so I seem to be pivoting back to the sandbag dome. Still waiting on that bit of engineering to be done tho. Hurry up and wait is the current motto.  There's no guarantee that the county will approve the placement of an earthbag home either.

Is there no way to get around this rule by maybe putting the container on some kind of trailer with wheels? Though even if that is allowed, not sure how the cost of that would compare to alternatives.

They have an approved list of vendors I could purchase from if I wanted to do something like that. 🤷‍♂️ I believe they also do not allow any homes on wheels.
