NFPA 13R Basement- What is the Hazard?

Hello 

 

I am working on a fire sprinkler design/drawing for a 3-Story R-1 Tourist Home, District R-3. They are converting an existing, three-story, single family home into a five unit, short term rental apartments. The building is to be fully sprinklered, NFPA 13R system. 

There is also a basement. I asked the GC what the basement was going to be used for. He stated "unused", but there is already a new electrical panel and a water heater in the basement. 

 

My questions is, what would the hazard for the basement be if the entire building is to be sprinklered per NFPA 13R? I'm assuming I should treat it as a worse case scenario and go with Ordinary Hazard Group II but I am currently trying to find the answer of what the hazard should be for the basement.

 

Any help would be greatly appreciated

Thank you
