Abstract
(HB5584 · 103rd Legislature) Land use: zoning and growth management; duplexes; permit in single-family residential zones. Amends sec. 102 of 2006 PA 110 (MCL 125.3102) & adds sec. 517. Sponsor: Rep. Joey Andrews (D) + 19 co-sponsors Latest action (2026-05-14): Rep. Sharon Macdonell Removed As Cosponsor
Why this matters
Requiring duplexes in single-family zones would preempt a core element of local zoning authority in Michigan, expanding the range of housing types builders can construct as-of-right in the state’s most restrictive residential districts. For homeowners, developers, and municipalities this represents a significant shift in land-use control and potential housing supply, with implications for property values, infrastructure planning, and neighborhood composition.
