I'd like to ferment in my garage since there isn't much space in the guest bedroom but I can ferment there if need be.
Safe? Sure, I supppose. It's not like it will spontaneously combust.
Suggested now that is the question. And the answer is, if uncontrolled, then No. Temps in the carboy are about 10*F above ambient. So, it's possible if you are fermenting in a 90*F garage than your beer is at 100*F.
There are some Belgian yeast and some Farmhouse Ales that take advantage of high heat temps but even then it usually limited to 80*F fermenting temp.
At those temps you are likely to creat a lot of fusel alcohols and that isn;t good beer.
