Egress From Third Floor Residential
It is my understanding that egress from a third floor in a single family home per the IRC requires two separate stairs. Two floors and you can have a stair and a jump platform, but three floors you will need two stairs. Is that correct? I recently saw a home built. Passed through inspections and everything where there were three floors and only one stair. The floors were labeled lower floor, second floor and third floor. The Lower floor was half garage and half bedroom. The bedroom side could be considered basement as 3-4 feet was retaining wall. The footprint was 20x45 with the garage facing the street and the bedroom facing the back. Lot sloped from back to street. Was one stair allowed because this lower floor was not the first floor but a basement? Even so, I would have labeled the plans, lower floor, first floor and second floor. Or am I reading the code entirely wrong?
