It is if there is a bedroom above it.A residential garage ceiling is not fire rated.

If habitable space above, they have 2 hour rating. Double 5/8" sheetrock. At least in this area.A residential garage ceiling is not fire rated.
Perhaps my fire rating comment was a little snarky. My point is that the IRC requirements for garage fire issues are not rated assemblies as in commercial. The IRC just has some basic requirements to slow down a garage fire. One example is as you mention, if there is a habitable room above you need 5/8 sheet rock on the ceiling but it says nothing about outlet penetrations and the like as you would have in a rated assembly. Other wise in most cases the garage can use 1/2 sheet rock.It is if there is a bedroom above it.
It is allowed but you have to follow the rules about such things.I have always done this. Always passed the electrical inspection. i see many other new houses like this. The city building inspector does not think it is allowed. Thanks
725.126 is not in my 2011 or 2017. I assume you meant 725.136 (which is in both). I have a single gang box, so I cannot use a barrier 725.136(B). But maybe you are referring to 725.136(D) 2 b. I do not know if that refers to the 18/2 from pushbutton to opener.It is allowed but you have to follow the rules about such things.
take a look at 725.126. read carefully what it actually says and not what someone told you it says, or what you think it says.
I agree. I've always stubbed a few inches from the box. The LV 18-2 does not need to be in a box per the NEC.I just stub it down a couple inches away. I don't want to have opener wire anywhere need the cover. Sometimes I go to the opposite side of the truss. Drywall hangers just poke out and some firecaulk it.
Sorry. You are right. I fat fingered it. Should be 725.136.725.126 is not in my 2011 or 2017. I assume you meant 725.136 (which is in both).

Like I say every EI has passed this, at least a dozen, over the last 20 years. Some very strict, some not. Thanks.
