... For instance, a mobile home single wide starts at about 320 square feet. So minimum size is not necessarily an issue. Additionally, there is a market segment for this concept on rural acreage where such codes are irrelevant.
Codes are often written and rewritten to meet new technologies. ...
I live in a rural "unincorporated" part of the county. County rules apply. 850 sq ft minimum. I know this because when I built the guest apartment above my garage they required it meet the minimum standard for living quarters since that is on an adjacent piece of property. I treat it as part of my home, but it is a separate lot with a common property line. So the guest apartment is 850 sq ft.
In a town or a city they are allowed to have their own minimums (at least that is the way it is in my county) so Gary, an hour away, has a couple mobile home parks, which are allowed there as their law supersedes the county minimum. There are no mobile home parks in the rural part of the county. There are some modular homes in the rural part, but they are pretty big, double wide PLUS and attached garages. I know of one modular that is 3000 sq ft and arrived on multiple trucks, requiring a crane to lift the parts into place.
