I am trying to find whether or not in the code if I can tap off a 30amp 240v receptacle for a portable space heater in a commercial space onto an existing 60 amp circuit. This is in a large pottery studio, and this is for seasonal heating in berkeley california, and it would not be used at the same time as the kiln that the circuit supplies....but I could not find any ref. about multi outlet appl. circuits and ocp in 2005 nec?

If you change the breaker to a 30A
crs you ever get anyone to wire your Mom's house?
Design-Build isn't supposed to mean design *as* you build.
Also, don’t forget that since this is a branch circuit and not a feeder, the length of the #10 tap conductors would be limited to 18-inches by 210.19[A][4][c].
I should clarify that that the #10 taps will only work if you hardwire the heater. Since you want add an additional receptacle, it must be the same rating as the branch circuit.
The closets thing you can do and meet code is install a small subpanel then install 30 and 60 amp breaker. The hassel may not be worth it because of the clearence requirements for the panel.
