A broad coalition of business, environmental, and housing groups is pushing Michigan lawmakers to pass a package of zoning reform bills that supporters say would help close a housing shortage driving up costs across the state.
The bills, known as the Housing Readiness Plan, were introduced in February by state Reps. Joe Aragona (R-Clinton Twp.) and Kristian Grant (D-Grand Rapids) with bipartisan backing. The package would let property owners build duplexes in single-family residential zones near metropolitan areas, allow accessory dwelling units on lots with single-family homes, and update the process for protesting zoning changes. It’s the kind of density-first approach that housing advocates have pushed for years in Michigan, and it now has an unusually wide political tent behind it.
Groups signing onto the push include Americans for Prosperity, Abundant Housing Michigan, the Michigan Environmental Council, and the Home Builders Association of Michigan. That’s conservatives, environmentalists, and housing advocates agreeing on something, which doesn’t happen often in Lansing.
The numbers behind the push
The median Michigan home sale price hit $270,000 as of March 2026, according to the coalition’s press release. That’s not a Detroit-specific problem. It’s statewide. And the inventory picture is worse than the price tag alone suggests: a balanced housing market typically carries about six months of available homes, but Michigan has only three months, according to the National Association of Realtors.
The rental side is even tighter. Michigan has just 37 affordable and available rental homes for every 100 extremely low-income renter households, according to the National Low Income Housing Coalition. Three out of four extremely low-income renters spend more than 30 percent of their income on housing and utilities, which puts them in what housing experts classify as severe cost burden territory.
For Detroit renters already stretching every dollar, that threshold isn’t abstract. It means choosing between rent, food, and everything else.
What the bills actually do
The Housing Readiness Plan doesn’t tear up zoning codes wholesale. It targets two specific tools: duplexes by right in single-family zones near metro areas, and accessory dwelling units, which are smaller secondary homes built on the same lot as a primary residence. Both approaches add housing supply without requiring large new developments or major infrastructure investment.
Dawn Crandall, executive vice president at the Home Builders Association of Michigan, said the plan would cut through the regulatory delays that drive up construction costs before a single foundation is poured. “The Housing Readiness Plan can help lower costs by reducing land use, modernizing outdated laws and regulations, and cutting lag and costly delays,” Crandall said. “Michigan needs policies to keep up with real world conditions, and we know exactly what contributes to rising homebuilding and residential expenses.”
The bills also draw support from groups that don’t usually frame housing as their core issue. Ross Gavin, urban land use and infrastructure policy director at the Michigan Environmental Council, said denser housing patterns are tied directly to climate and transit goals. “Increasing housing density is a key element in establishing walkable, vibrant communities,” Gavin said. “The Housing Readiness Plan is a step toward Michigan communities reducing carbon emissions, encouraging economic development, and promoting multi-modal forms of transportation.”
Bipartisan introduction, uncertain floor vote
Aragona and Grant introduced the package together in February, signaling an attempt to build cross-aisle support from the start. The Michigan Advance has tracked the coalition’s formal call to leadership to move the bills to a floor vote. Whether House and Senate leaders schedule that vote is the open question. Zoning reform touches local control, a pressure point for lawmakers in both parties who hear from municipal officials protective of their land-use authority.
Abundant Housing Michigan and allied groups have spent months making the case that local control arguments don’t hold when local zoning decisions produce a statewide supply crisis. The three-month inventory figure is the sharpest piece of evidence they have. A six-month supply represents equilibrium; Michigan is running at half that.
The coalition is also leaning on an economic argument that reaches beyond homebuyers. Gavin pointed to workforce retention as a direct consequence of housing costs. Workers who can’t afford to live near jobs leave the region or don’t come at all. That argument carries weight with business groups and with legislators who represent suburban and exurban districts losing young workers to other states.
The Housing Readiness Plan is now before the full Legislature after its February introduction, and the coalition’s public push is a signal that supporters want a vote before the session calendar gets crowded with budget negotiations later this spring.
