Grounding electrodes at outbuildings

I would agree with you. What do you think people will say when you try to make them fix it???

Also are you sure it is a manditory requirement in your area?

If it’s an existing building without a 4-wire feeder, this code applies:

3-wire feeds to existing detached buildings

Regardless, unless it’s a single circuit, all outbuildings require a grounding electrode per the 2009 IRC. Read the commentary in the above link for existing buildings.
