Location: Florida – City has adopted 6th Edition FFPC (based on NFPA 101 2015 edition)


A one-hundred year old two-story residence on the National Register of Historic Places is undergoing Change of Use to single-tenant business use, no change in hazard classification.  ~2,400 total square ft.  Building is non-sprinklered.


Does single exit provision in apply when maximum distance traveled is 70 feet from furthest point in second floor to first floor exit?  Traversing stairs is necessary, but less than 15 feet of height.


Note: Interior stairs are not enclosed; however, doesn’t the following apply from Historic Building section Stairway Enclosure? Local design professional believes this suffices.


Based on 101 and other local Checklists for Business Occupancies, it seems like single exit provision should be allowable, please maybe I am missing something?
