Michigan Housing Readiness Package Advances Pro-Growth, Pro-Property Rights Reforms

Michigan lawmakers have an opportunity to advance a package of reforms that would make housing more affordable, expand property rights, and remove government-imposed barriers that prevent the free market from meeting housing demand.

The Housing Readiness Package (HB 5529-5532 and HB 5581-5585) takes a commonsense approach to one of the most pressing issues facing Michigan residents today: the high cost and limited availability of housing. Rather than relying on taxpayer-funded subsidies or government-directed development, these reforms focus on reducing regulatory burdens that artificially restrict housing supply and drive up costs for families.

Housing affordability has become a top concern for voters across Michigan. Years of restrictive zoning rules, excessive land-use mandates, lengthy permitting processes, and outdated development regulations have made it more difficult and expensive to build new housing. When government limits what can be built and where it can be built, the result is fewer homes, higher prices, and fewer opportunities for families, young professionals, and retirees.

By protecting property rights, reducing unnecessary regulations, and allowing builders and property owners greater flexibility, these reforms help create the conditions for more housing to be built. Increasing housing supply through market-driven solutions is the most effective way to improve affordability over the long term.

Taken together, these bills represent some of the most significant pro-housing, pro-property rights reforms under consideration in Michigan. They would lower development costs, increase housing options, create greater certainty for builders, and help ensure that local regulations do not unnecessarily stand in the way of housing construction.

HB 5529 and HB 5530 — Reform Minimum Lot Size Requirements

HB 5529 and HB 5530 establish a maximum minimum lot size of 1,500 square feet for single-family homes in metropolitan areas. Excessive lot-size mandates force developers to build larger and more expensive homes than the market may demand, limiting housing supply and driving up costs. These bills allow more efficient land use while expanding opportunities for homeownership.

HB 5531 — Create Certainty in the Development Review Process

HB 5531 establishes clear timelines for local governments to review development proposals. Municipalities would be required to review applications, identify any needed studies or additional information, and then make a final approval or denial decision within 60 days after receiving completed materials. Predictable permitting processes reduce delays, lower costs, and encourage investment in new housing.

HB 5532 — Modernize the Protest Petition Process

HB 5532 updates Michigan’s protest petition process by expanding the petition area to 300 feet while establishing a clear 60 percent signature threshold. The reform ensures that petitions reflect broad neighborhood sentiment while providing greater consistency and predictability for local decision-makers considering housing projects.

HB 5581 — Allow Smaller, More Affordable Homes

HB 5581 caps minimum dwelling size requirements at 500 square feet in metropolitan statistical areas. Many local governments impose minimum size mandates that make it difficult to build starter homes, smaller residences, and other lower-cost housing options. This bill expands opportunities for more affordable housing construction.

HB 5582 — Reduce Costly Parking Mandates

HB 5582 limits mandatory parking requirements to no more than one parking space per dwelling unit. Excessive parking mandates increase construction costs, consume valuable land, and often force developers to build parking that residents may not need. Reducing these requirements lowers housing costs and encourages more efficient development.

HB 5583 — Modernize Setback Requirements

HB 5583 establishes statewide setback standards in metropolitan statistical areas of 15 feet from the front property line and five feet from side and rear property lines, while preserving exceptions for environmentally sensitive areas. The reform allows property owners to make more productive use of their land and reduces unnecessary restrictions on development.

HB 5584 — Permit Duplexes in Single-Family Zones

HB 5584 allows duplexes in single-family residential zones located within or adjacent to metropolitan statistical areas and provides a clear statewide definition of a duplex. Allowing duplex construction increases housing supply and creates additional housing options without fundamentally changing neighborhood character.

HB 5585 — Expand Accessory Dwelling Units

HB 5585 establishes a statewide framework for accessory dwelling units (ADUs), allowing them on parcels with single-family homes, limiting setback requirements to five feet, prohibiting additional parking mandates, and allowing both attached and detached ADUs. These reforms create additional housing opportunities for seniors, students, caregivers, and working families while allowing homeowners greater flexibility in how they use their property.

The Housing Readiness Package recognizes a simple reality: Michigan cannot solve its housing affordability challenges without allowing more housing to be built.

By reducing regulatory barriers, protecting property rights, and allowing the private sector greater freedom to respond to consumer demand, these bills will help increase housing supply and improve affordability across the state. Michigan lawmakers should support these commonsense reforms and take an important step toward a more affordable and prosperous future.
