I am looking to see what others use as occupant load factors for individual apartments, based in NFPA, not other Codes? There was confusion that each apartment was like a single family dwelling and therefore had to meet the requirements under 24.1.1.2 (single family no more than 3 outsiders in rented rooms), but there is no tie in to this from… (Show more)
