Covered Malls Fire Protection

[odelgado]

Greetings,

I have a three story covered mall with a combined standpipe system. It's in Puerto Rico so the governing codes are NFPA and UBC with the approval of the AHJ. As far as I know, the building should be sprinklered throughout, yet the unoccupied tenant spaces are not. They were left with a 4" capped provision to allow the future tenants to install their own sprinklers system with individual control valve. The lease contract requires the tenant to do so, so at 100% occupancy the building should be sprinklered throughout. Is this allowed by code, or must the owner install sprinklers in the unoccupied tenant spaces and then require the tenant to modify the layout as necessary?

Thanks for your time.
