Floating Walls Needed in Maryland?

Does anyone know if Maryland code requires constructing "floating walls" in the basement? I am currently starting framing a few walls in the basement and did not even think about the concept of a floating wall until I read about them online. Most of the info appears to be from Colorado (something to do with clay soil and drastic weather fluctuations).

Also, if I am to construct floating walls, what is the recommended gap? 1/2", 1", etc.? I would prefer to keep the gap as small as possible.

BTW, Frederick County is where I live. I know soils may differ from the mountains to the shore.

From the information I have, no. However, we are not the authority. Check with your local building code authority for ANY construction method you may not be sure of. Special soils may require special treatments. Where we live in the mountains, we cannot use sonotubes for individual deck post placements unless it is on flat soil. We must use a continuous 12" x 24" deep footing. So check before you build it.
