Hey Ron - You'll want to double check with an inspector but my understanding is that your ceiling IS a fire-block. As long as you've fire-blocked the access to that empty space, you're good to go. In other words, there shouldn't be any additional fire-blocking needed than what I'm describing here. Again, consult your local code / guy / girl inspector - but this is my understanding. - Jason
I dropped my basement ceiling by 3 inches to cover some pipes and AC lines that were running on the joist. do I have to fireblock that drop and how?
