Max. rebar spacing in masnory
(OP)
I am designing an interior masonry wall for some lateral load and I have determined that I need very little rebar. Is there a maximum rebar spacing limitation in the code somewhere, because I would like to place the bars @ 72" oc but I have noticed that most engineers tend to place the bars not farther then 48".

The MSJC (ACI 530,etc.) has a requirement that the maximum "flange" width in bending in a wall is limited by bar spacing, 72" or six 6) times the wall thickness.
With typical 8" thick wall, that would put your effective B at 6x8 = 48". So going beyond 48" you are not getting any additional flange width help. Not a huge deal but consider it.
Also, section 1.17 has numerous requirements for minimum reinforcement in various seismic conditions.

I beleive a 6" wall is more practical for something non-bearing as this is and could be reinforced if desired.
