I need to find the definition of a residential 1 hour firewall. The wall in question is in a detached garage that is within 3 feet of the side yard property line. I've install 5/8" fire-rated drywall on both sides of the studs w/ blocking b/w the joist. The inspector says I need to tape and bed the wall to complete the 1 hour rating. I've built this wall w/o tape and bed over 100 times and now they have are saying that's not correct.
The head building inspector says they don't have anything that states tape and bed is necessary and said I need to show them something that is UL approved that doesnÃ¢â‚¬â„¢t show tape and bed.
Thanks for your help.
