We are having our old deck replaced. What should I expect as a "normal"
spacing
for the balusters on the railing?

In the middle of this myself. National Building Code requires that a 4"
sphere cannot pass between any point of the railings (including underneath
any shoe rail), and that a 6" sphere cannot pass through the triangles
caused by a shoe rail on the angled stairs.

Local codes may vary, but most follow the NBC. This should be covered in
your plan review when you pull the permit as well...
