1023 Interior exit stairways (2015 IBC)?
April 20, 2015
The question of whether a horizontal assembly is required was up for debate recently in our office. The Multi family R-3 Apt building is fully sprinkled. There are two interior stair wells, one on each end of the building. Should the ceiling of the interior stairwells be constructed as a horizontal assembly? This is NFPA 13R protected building.
