2006 IRC P2904.1.1 says garages are excempt from sprinklers. It does want sprinklers in normally unoccupied concealed spaces in attics and crawl spaces that contain fuel-fired equipment. It also excempts drywalled clothes/linen closets and pantries less than 24 sq. ft.. Does a closet with a gas waterheater in it in the garage need sprinklers?
