AI Summary

This bill, effective January 1, 2027, amends county and municipal building codes to allow residential buildings with up to six stories above ground level to have a single stairway as the sole exit for all units, provided specific safety measures are in place. These measures include an automatic sprinkler system in the interior exit stairway, self-closing devices on all dwelling unit doors that serve as exits, comprehensive smoke detection in common areas and individual units, at least one emergency escape and rescue opening per dwelling unit, and no more than four dwelling units on any single floor. The bill also limits the authority of home rule units, which are local governments with broad powers, to enact regulations that contradict these provisions, asserting this as a state-level limitation on their concurrent powers.
