The NEC only requires one rod, but if you don't have equipment to determine
the quality of the ground connection, you're required to drive a second rod
six feet apart. For most of us, it just means you drive two rods

We agreed to install 2 ground rods, per code, and then tie a second

Guessing you live in a dry rocky soil area. Since code only requires
one ground rod if a sufficient low ground resistance.

My town requires two rods on any new service or panel upgrade, 5' apart
IIRC, and it is all farmland. Probably just some towns go code+.
