How to prove there is a ground rod

250.53 indicates for for a single rod it must be supplemented by another unless you can prove 25 ohm or less.

If this is a home inspector that is making a fuss take with a grain of salt as an original historical installation it would have been inspected before the power was turned on by the POCO. If a purchase agreement was being held up all code requires is a second rod at least six feet from the first. Anywhere accessible beyond that meet the code and just drive one and done.

If this is an electrical inspector AHJ then either proof of resistance or proof of electrode would be required.

This is a home inspector. If I were the seller, I’d point him to the final inspection approval sticker on the panel and tell him to pound sand. It’s unlikely that the buyers will push the issue unless they got cold feet regarding the purchase for some other reason.
