Yes building permits are required for additions of any kind
It depends on where you live. The footings have to be 1' below deepest expected frost depth.
What county are you in? what altitude? Footings should be 24" wide
Charts show 25" frost depth for Colorado Springs so your footing would have to be 37" deep but check with your local building inspector to see what they require.
Do you have any more questions?
