Michigan Zoning Reform Bills Would Preempt Local Control Over Housing Development as West Michigan Officials Voice Concerns

State Housing Bills Target Local Zoning Authority Amid Growing Debate Over Affordability

Michigan lawmakers introduced a package of housing bills designed to reduce zoning restrictions across the state, but the proposal has sparked intense debate between housing advocates and local officials who fear the loss of community control.

Representatives Kristian Grant and Joseph Aragona introduced House Bills 5529 through 5532 on February 18, 2026. The legislation would pre-empt certain local zoning ordinances and significantly restrict what municipalities can require for new residential development.

What The Bills Would Change

House Bill 5529 and House Bill 5530 would prohibit local governments from requiring minimum lot sizes greater than 1,500 square feet for detached single-family residences where the property has access to public water and sewer. Currently, state law allows municipalities to set minimum lot sizes up to 12,000 square feet.

House Bill 5584 would mandate duplexes as a permitted use in any district where single-family residences are allowed. House Bill 5585 would require accessory dwelling units to be permitted by right in residential zoning districts.

House Bill 5583 would establish setback requirements of 15 feet or less from the front property line and five feet from side or rear property lines for dwellings and outbuildings in areas within or adjacent to a metropolitan statistical area.

Representative Aragona, chair of the House Committee on Regulatory Reform, began taking testimony on the bills on February 26, signaling swift movement through the legislative process. The bills are currently before the Government Operations Committee.

The Case For Reform

During a March 11 roundtable discussion hosted by the Mackinac Center for Public Policy, Rep. Kristian Grant of Grand Rapids said young people are literally praying for a market crash to afford homes. Rep. Joseph Aragona of Clinton Township noted home prices have increased by more than $100,000 in some areas of the state in the last five years. Rents in some places have doubled.

Lauren Strickland, executive director of Abundant Housing Michigan, supported the legislation. Tran Calvin, a Grand Rapids filmmaker and board member of the organization, said his rent on New Yorks Lower East Side rose from $2,800 to $4,000 during his time in the city.

Michigans current vacancy rate stands at 0.9 percent, Calvin said, calling that amount far below a healthy level of 5 percent. The state lacks roughly 119,000 homes, according to the Michigan Infrastructure and Transportation Association.

Calvin pointed to local governments as sometimes contributing to the problem. The city of Walker bans accessory dwelling units. Kentwood, also in the Grand Rapids area, requires a minimum lot size of five acres in rural residential areas.

In Southeast Michigan, Rochester Hills requires one acre for homes in its lowest-density residential zone and half an acre in the next-lowest-density zone. Calvin said Detroit has effectively locked out 82 percent of its vacant lots from development by lot size and setback requirements.

The Case Against Preemption

The Michigan Municipal League is actively opposing the bills through a petition campaign. John LaMacchia of the organization said the legislation would strip locally elected officials of their decision-making authority and dismiss years of community planning work.

The bill package would significantly restrict local authority by preempting local decision-making on key zoning issues including duplexes, accessory dwelling units, minimum setbacks, lot sizes, and dwelling unit sizes.

Supporters of preemption often point to declining permits, rising home prices, and regulatory costs as justification for statewide mandates. The Michigan Municipal League argues these pressures are driven by broader economic forces including the housing crash, rising labor and material costs, high interest rates, and complex market dynamics that go far beyond local zoning.

Sweeping mandates oversimplify the problem and ignore the unique needs and circumstances of Michigans diverse communities according to the organization.

The Michigan Association of Counties was not consulted in the drafting of the legislation and is still evaluating the bills. MAC has not yet taken a formal position on House Bills 5529 through 5532 or related proposals.

Local Concerns

The Michigan Association of Counties notes the proposal represents a significant shift in the balance between state authority and local zoning control. Counties and municipalities that currently impose larger minimum lot sizes could be required to amend their ordinances to comply with the new statewide standard.

By tying the reduced lot size threshold to access to public sewer and water, the bills are designed to focus growth in areas where infrastructure can support it. However, counties that currently require larger lot sizes for environmental or other reasons would face significant changes.

As testimony continues before the House Committee on Regulatory Reform, lawmakers are expected to hear from developers, local officials, housing advocates, and other stakeholders on the potential impacts of the legislation.

If enacted, the package would mark one of the most significant state-level zoning pre-emptions in recent Michigan history, reshaping how communities regulate residential development in areas served by public utilities.

What Comes Next

Representative Aragona wants to speed up the permitting process. The Michigan Department of Environment, Great Lakes, and Energy takes an average of three to four months to review a permit according to the representative.

The bills would also modify protest petition signature requirements and pre-empt certain local regulations affecting accessory dwelling units. House Bill 5532 would expand the qualifying petition area to 300 feet and set a 60 percent signature threshold for protest petitions.

If approved by the Senate and signed by the governor, the measures would formally restore and strengthen programs designed to help protect Michigan homeowners from losing their homes due to special assessments. The legislation now heads to the Michigan Senate for consideration.
