Jurisdiction is CA. I have a two story Type V-B non sprinkled building. Maybe 8,000 SF total. Currently there is an open stair at the entry area that connects both floors without an enclosure. At the rear of the building there is an exit stair that is enclosed and leads to a exterior door direct to the outside. It appears to be 1-HR rated. I was under the impression I needed to maintain the one enclosed stair, but reading thru here it seems like with only two floors connected the enclosure can be excepted? what am I missing?
