Nope, even your garden shed has to be built to wind code. We don't see
many of those sheet metal things they sell up north and if they are
here, they were put in without a permit (illegally).
There is no exception for size, square footage, portable or any of the
other dodges you get in other places. It is more about them becoming
flying debris than the loss of the shed itself.

There's a trailer park (quite a nice one, thus far) located just
west of our property. We've always imagined trailers rolling across
our lawn like tumbleweeds while we sit snug in our concrete block
house. Of course, our roof would present some difficulties for those
downwind of us, since I think it's held on by gravity. Still,
in 70 years it hasn't gone anywhere. Knock wood.

Most northern homes are pretty much held together by gravity. The
trusses are toe nailed into the top plate and that is end nailed into
the studs.
If it is sitting on block there may not even be nuts on the "J" bolts
that are just mortared into one cell of the block holding the top
plate down.
In Florida the roof is continuously connected to the foundation by
simpson connectors and block walls are reinforced with about 20% of
the cells poured solid and #5 rebar continuous from the foundation to
the 16" poured tie beam on top. Then embedded straps go over the
trusses.

They have required tie downs on trailers since the 60s and they have
to meet the same wind code as a site built home. There was a time
around 2000 that nobody in the US built a Florida compliant trailer.
It was a problem because you can't get a permit to move an existing,
non-compliant trailer and install it somewhere else.

What "J" bolts? We don't need no stinkn j bolts up here. We have enough dead
weight in PA to hold everything down...

Until you don't ;-)
Most hurricane damage to structures is because of uplift and internal
pressure lifting the roof off or taking a stick built house right off
the foundation. You guys saw that during "Mediocre Storm Sandy" that
was only "super" because the houses were not built to take even a
minimal tropical storm.
