Abstract
(HB5571 · 103rd Legislature) Construction: code; single exit stairway in multiple-family dwellings with not more than 6 levels; allow under certain conditions. Amends 1972 PA 230 (MCL 125.1501 - 125.1531) by adding sec. 4j. TIE BAR WITH: HB 5570’26 Latest action (2026-07-03): Bill Ordered Enrolled
Why this matters
This companion bill narrows the state construction code to explicitly cap the single-exit stairway allowance at buildings of six levels or fewer, clarifying design parameters for developers and builders of small- to mid-rise multifamily housing. For workers in construction and for renters, the change could affect the cost, layout, and safety profile of new apartment buildings in Michigan.
