I inspected a house ysterday and found in the garage attic, access to the area above the living quarters. The living area is just behind the shovel in the attached picture (sorry if its not oriented correctly). The area behind shovel is the ceiling of the living area. This is the first instance where I have NOT seen drywall in the attic space.
My question is based on this:
Walls and Ceilings
The 2006 edition of the IRC states the following concerning garage walls and ceilings:
R309.2 Separation Required
The garage shall be separated from the residence and its attic area by not less than 1/2-inch (12.7 mm) gypsum board applied to the garage side. Garages beneath habitable rooms shall be separated from all habitable rooms above by not less than 5/8-inch (15.9 mm) Type X gypsum board or equivalent. Where the separation is a floor-ceiling assembly, the structure supporting the separation shall also be protected by not less than 1/2-inch (12.7 mm) gypsum board or equivalent.
Since the ceiling inside the garage IS of required drywall thickness/material from what I could determine, does that satisfy the IRC separation and thus, no drywall is needed in the garage attic space where pictured?
I am working on the report now.
Thanks in advance!!!
