Putting up a shop in CA - fire department being a pain

My son is outside Grass Valley. They were not allowed to put in a paved driveway (probably around 150'). The gravel was just laid on the dirt. It is unlikely the little single lane bridge over the creek to get to their place will support 70k lbs. Weird rules all over...Also, it would be very difficult to turn a large rig around at their place.
