If it is in a separate structure then it needs it own ground electrode system.
That might be one OR MORE ground rods and other electrodes.
If it is in the same structure as the service entrance then it only needs an equipment grounding conductor that goes back to the service entrance.

Bill,
Thanks for the response. I am looking to install a subpanel to avoid some long wire runs to my garage and garage attic. The garage is attached to the house by a breezeway... so not really a separate structure. Next question would be if it is o.k. to install the subpanel in a garage.... I know there are some different rules when it comes to garages.
Yes you can have it in the garage unless there is some local code amendment against it.In fact it is very common for main panels to be in garages..
