The bill amends the existing construction code in Michigan to allow for specific conditions under which a multiple-family dwelling with no more than four levels above grade can have a single interior exit stairway. The new section 4j outlines several criteria that must be met for this allowance, including limitations on the number of units per level, the maximum net floor area, and the exit access travel distance. Additionally, it specifies requirements for openings to the stairway enclosure, the installation of fire alarm and smoke detection systems, and the placement of smoke detectors in common areas.

Furthermore, the bill mandates that the interior exit stairway must comply with certain safety standards, including width and the absence of electrical receptacles within the stairway. It also requires that automatic sprinkler systems in the stairway adhere to specific installation standards. The enactment of this bill is contingent upon the passage of House Bill No. 5571 from the 103rd Legislature, and it is designed to take immediate effect upon approval.
