Metal Piers approved supports?

I know these metal piers are typically used for mobile homes but I can’t find anything either way whether they are approved to support a girder in a stick built home. Home originally built 1930 but was moved at some point. The weird part is that they are on a proper poured footing and the other side of the home has a typical wood framed support wall on a footing that looks like it was poured at the same time.
