The normal range in our neighborhood is from 6" up to 36".
One house has a space of just 4". They all look ok and I've
noticed that few of my neighbors even realize that there is
such a variety around them. Few folks even notice.
Besides looking in the local code, you can quiz your local code
enforcement people. You can also phone the zoning folks in
nearby communities to get a variety of free opinions.

I can't find this in the local code. Is there a recommended minimum
the bottom of a second story window, and the top roof line of a porch
below? Is 6-8" sufficient? Thanks,
