Deems meeting the criteria for either a mid-rise or low-rise qualifying R-2 building and all universal requirements to constitute compliance with the means-of-egress requirements for exit stairways under the North Carolina Fire Code and any applicable local ordinances. Directs the Building Code Council to amend the Building Code to conform to the described directives and sunsets the act on the date the adopted rules become effective.
