The original reason for the 1" space around the anchor bolts was to see if
the bolt had grout around it. Nothing magical.
If you, or the jurisdiction wants proof that there is grout around the
A.B.'s, drill some small (1/4") holes --- if you don't hit air after
1-1/2 inches, you have grout.

Thank you Roger for the clarification. The bolts are actually set in 1-1/2"
diameter holes, leaving about 1/4" space all around. The problem is that some
inspectors and building officials will stick to the letter of the code if
they don't have the reason behind a specific code language, such as your
explanation for the 1" clearance requirement around anchor bolts.
