I did an inspection that had many joints in the sheet roock not taped and mudded. This garage sits under bedrooms. Is there an ‘official’ stance about having the joints mudded? Gaps are small, so concerned with carbon monoxide, gas fumes, etc.
I can go with common sense, but in the building industry, this doesn’t play fair. 
thx,

If your local codes has a “gas and vapour tight” provision for garage walls/ceilings separating the garage from house living areas, then the gaps must be sealed of which rough tape and mud is the easiest solution.
In my area, all firewalls seams must be taped and compounded. If not, I red flag it…
Any mention of taping seams under the ICC? Anyone?
