House trailor foundation
(OP)
Does anyone have any details for a foundation for a Mobile home (mobile home park) like "permanent/temporary ( ...I jest)
I see nothing about it in the NBCC (National Building Code of Canada) – 2005 .... (2010 out now but not in widespread use yet)
I have heard of the use of piles and grad beam (kinda permanent) and some also some sort pad and post setup c/w a cable and screw anchor ... to keep it from blowing away !
The building inspector has advised the owner ( who wants to plunk it down on some plank pads) that the foundation has to be certified by an Engineer (good idea)

After all it is a "Mobile" Home. It's supposed to move!
The Mobile home manufacturer should have the foundation and tiedown instructions in the manual that came with the home, if the owner has it. Just carry it below frost.

A mobile home is supposed to be moved yes... but if it is not wrack resistant differential settlement of individual piers would damage the building.
Heaving of highly plastic clay results from seasonal volume changes (heaving and subsidence i.e. expansion due to increase in moisture content and settling due to drying). ..... more serious actually than changes due to frost.
The Owner would like to set in on the grade ... circumstances listed above (and possibly Codes) could dictate otherwise.

In Florida, manufactured homes themselves are not under the building code. Any site built additions or appurtenances must comply with the building code, but the mobile home itself has to comply with HUD standards as you noted for the Federal requirements.
Florida has supplemented these requirements to accommodate anchorage for high winds.
It was interesting to see that 30 or so years ago, anchorage of mobile homes was from the frame to the ground. That didn't work, since wind would just blow the weak walls away from the transport frame (which we could then buy and make some terrific utility trailers). Then came the requirement that anchors would incorporate the roof as well. Still doesn't work when the winds get high.

The financeers will not accept this out for the owner for existing mobile homes, and in this is the problem. They want the engineer to accept all of the responsibility and liability, not them, and we are painted as the bad guys when the loan fails. Go figure.
I, too, have stopped doing any of these for exactly that reason. I have enough situations where I have to be the bad guy. This is not one of them.

It is also possible to construct a frost wall either of concrete or masonry on a perimeter strip footing.
Both can be insulated and provide a crawlspace.
Alternatively, it's possible to construct the perimeter support using gradebeams and friction piles or some other type of piling.
Most areas of the prairies that I've done work in, frost penetration is typically 6' min...

This is presumably to guard against differential vertical movement causing damage to the superstructure.
