I am currently working a project converting a 8 storey religious building from 1850 into a residence for low-income people in Quebec City, Canada. I'm having a hard time deciding what is considered a closet ( and would require sprinklers) and what is considered a wardrobe that would not require protection. Could anyone tell me which of the following picture would require sprinkler protection and what are the criteria ? If possible provide NFPA 13 articles other than 8.1.1 (7). Thank you all !
