Your never required to bond rebar by the NEC, but if 1/2" or larger rebar, 20' or longer exists in the footing the NEC requires you use it as a grounding electrode. See 250.50 and 250.52(A)(3)

It's as iwire has pointed out with the possible exception being if you're still on the 2002 NEC the wording at 250.50 says "if available" which is a lot different than the '05 which says "where present".:smile:

Check out the sections that Bob posted. Chances are very good that you'll need a CEE in any new building even a residential dwelling.

Is there typically rebar in resi foundations in your area?
There never seems to be any on the houses I wire. I always try to get #4 in there anyway to avoid ground rods.

That really differs depending on the area you are located in. In areas that have high seismic designs you are almost assured to have lots of reinforcing bars in both the footings and foundations.

There is always some reinforcement in the footing. I have seen some #3 rebar which would eliminate the requirement for a CEE.

One of the last homes we did had no rebar in the footings so we used some bare cu. Only inspector ever to visit the site was the electrical inspector.
