Renovating portable office into home

Is it worth while to buy a portable office and convert into a home? Anyone ever do this before? Regulations?

Yes, I’ve done it. No, I would not buy one for that purpose. But in my case, it was already there, and I had to do something with it. It’s not that hard to add the bath/shower as the plumbing is already there (assuming it already has a bathroom). But, in the end, what you have is an efficiency mobile home. And those are nearly impossible to rent as nobody wants to live in anything that small. If you are in an area of fracking, maybe an oil worker would be OK with it, as many parks in man-camp areas rent the homes by the bedroom. But you would be far better off buying a real mobile home than doing what you’re proposing.
