Hello there, I am putting in a drywalled ceiling in my basement. I had to use 5/8" drywall as fire-blocking between the stud wall and foundation, but planned on using 1/2" drywall for the actual main ceiling since my joists are close enough together to allow that. However, I read on this forum that 5/8" rock might be required for fire protection for the main ceiling, by code. Since I am doing this with the proper inspections, can anyone shed light on this? Is it in the national building codes, or is this a one-off requirement of some jurisdictions? Thanks.
