In my case, I'm re-doing an attached garage on a house that was built in
1955.  I've stripped the walls and the ceiling was already open.  There
was nothing firerated on any wall, including the shared wall with the 

The plan is to insulate, wire, and sheetrock the walls/ceiling.  I was 
going to use fire-rated sheet rock for the walls/ceiling as a "good idea" 
type of thing...

I don't have a permit, don't know if one is required, and have no 
intention of getting one even if it is.

So, all that said, would I be smart to use 5/8" fire rated sheetrock or 
should I just use normal sheetrock?  Cost matters to me, and I don't 
partiuclarly want to have to manuver 5/8" sheetrock for a ceiling.  All 
that said, if fire rated sheetrock is likely to help in the event of a 
garage fire...
