The construction office in my town says footings need to be 30". I dug the corners and from the top of my slab to the bottom of the concrete is 24". How do I go about adding to this to meet the code so I can build on this slab?

What are you building?
Dig to the prescribed level (proper solution) or add fill.
If you add fill, you may have to change the level of slad. If you add fill, you will have to sell the official on the idea of filling later to provide frost protection and keeping your wood far enough the finished grade.
