Land use: zoning and growth management; minimum home size requirements; limit. Amends sec. 201 of 2006 PA 110 (MCL 125.3201) & adds sec. 205e.

HB 5581 sets a 500-square-foot minimum size requirement for new homes in Michigan, preventing local governments from imposing larger minimums through zoning ordinances. This directly affects homeowners, developers, and local municipalities that create zoning rules for residential construction. The bill amends Michigan’s zoning law by adding Section 205e, which explicitly prohibits zoning ordinances from requiring dwelling sizes greater than 500 square feet. It does not change other zoning regulations like land use types, building heights, or lot coverage. The bill is currently pending in the House Government Operations Committee.
