Hi Carmen;
If they require footings, you will need them. However,
footings can be just piers, rather than a full perimeter
footing. They likely run into many situations where
the existing mobile home is not on substantial footings,
and the addition is likely to be different construction.
So, settling may be potentially uneven.

Just because the footing is independent (likely what they
mean) does not mean that the whole structure is unattached.
That could get particularly difficult (or limiting) for the roof,
where the only way to do that would be to have the addition
roof meet the home under an overhanging eave which it may
not have.(or at least and overhanging flashing on a wall)
Connection between the existing and new structures
should be very well flashed, preferably using tape type
adhesive flashing, under metal lap type flashings, to seal
out unwanted air movement as well as water leaks.
