Go take out a building permit, like required. And while you're there
you can ask the building inspector. He/she may not give you an
answer, but an architect will.

Sorry, I thought Deck, a porch with roof needs support below frost
line.

Around here the building inspector has taken a liking to the
earth screw ground anchor. Screw down below frost line. I used them
for my decks a few years ago. No movement at all.

The link just shows the general idea.

The anchors I used had a threaded end and a adjustable bracket for
bolting to the wood.

They're called ground hogs around here. Home Depot has them.

I am in SE Wisconsin, and I believe that my local inspector made me go
42" deep here, but it could have been 48". Should be about the same
for you in Central WI, but you should probably verify with your local
building dept. I would be willing to bet that it will be 48" or 54".

Here in Iowa that's about what it is too. It is because the inspectors
want them to be below the frost line.
