Owner built a new garage with bedroom above in 2010, when was the ceiling separation rule from garage introduced ? I thing there should be sheetrock covering this ceiling, correct. ? Thanks
Yes…
If you look at it as a potential safety hazard, you don’t need to state dates of, or comment on, when certain codes came into effect.
The ductwork is also an issue and more difficult to correct. Sheetrock in this case needs to be 5/8 in Type-X. The requirement existed prior to 2010, but that is not important.
Great replies and I enjoyed the link Larry.
