Here is the applicable section from the IRC Mechanical Section M2005 on Water Heaters as a guide:
Note that “Living Space” includes areas for living, sleeping, eating or cooking (habitable space) as well as areas for bathing, washing and sanitation purposes (bathrooms). Many are surprised that a bathroom is considered “Living Space” under model codes (it’s just not considered “Habitable Space” … there is a difference) …
The question I asked has been well answered and I thank all of you who have taken the time to respond. This was my first use of the message board and it has been a good experience.
Thank you,

I know that about the water heater/bathroom/closet issue, but can someone technically explain why a fuel fired gas water heater is not allowed in bathroom/adjacent storage closet (with exceptions)? The obvious is CO poisoning and flammable chemical vapors. What else ?
I just inspected a home where the gas fired water heater was in a hall closet directly across from the bedrooms?? Would you consider that habitable space?
HABITABLE SPACE (ROOM) is space in a structure for living, sleeping, eating or cooking. Bathrooms, toilet compartments, closets, halls, storage or utility space, and similar areas, are not considered habitable space.
