When mixed-use buildings weren’t predominantly residential, the annex said NFPA 13 methods must be used all through. Non-residential portions of the building had to use NFPA thirteen design discharge and design space standards, but fundamental design decisions concerning areas to be sprinklered could probably be guided by NFPA 13R.
