The bill amends the Stille-DeRossett-Hale single state construction code act by adding a new section, Sec. 4i, which outlines specific conditions under which a multiple-family dwelling can have a single interior exit stairway. This provision applies to dwellings with no more than three levels above grade plane or an occupiable roof, and it stipulates that the dwelling must not exceed four units per level and a net floor area of 4,000 square feet. Additionally, it sets a maximum exit access travel distance of 125 feet from the most remote point within a level, and it restricts openings to the interior exit stairway enclosure to those necessary for exit access, egress, and exterior access.

Furthermore, the bill mandates that the dwelling must be equipped with a manual fire alarm system, an automatic smoke detection system, and an occupant notification system, all compliant with building codes. It also requires smoke detectors in common areas, adherence to sprinkler system standards for combustible stairways, and prohibits electrical receptacles in the interior exit stairway. These measures aim to enhance safety and ensure proper egress in multiple-family dwellings while allowing for more flexible design options.
