If a deck (more than 30" off the ground) has a row of benches built-in to the perimeter, do the guard rails need to be measured from the height of the bench? I've been reading building codes they all talk about measuring from the floor of the deck.
To clarify: The deck (and the benches, and the house) was built 20+ years ago. I understand that it could be safer, but is that a recommendation or a legal requirement? Is it up to code now, and if not, have the standards have changed recently, or was the original builder in violation?
