Housing Readiness Package
State Representative Kristian Grant
Building More Homes. Lowering Costs. Strengthening Communities.
Why It Matters
Michigan communities are experiencing a housing crisis driven by a shortage of homes that affects affordability
and limits options for residents of all ages. These reforms in this package set reasonable statewide guardrails
while preserving meaningful local input and oversight. The majority of these reforms apply within or adjacent to
metropolitan areas across the state, where housing demand is the highest.
Key Reforms
• Minimum Lot Size: House Bills 5529 & 5530
(Reps. Kristian Grant & Jennifer Wortz): Sets a
2,000-square-foot minimum lot size for single-family homes
in metro areas, preventing overly large land requirements
that make housing more expensive.
• Smarter Parking Rules: HB 5582
(Rep. Kristian Grant):
Caps mandatory parking requirements at no more than one
space per dwelling unit. This lowers costs for builders and
families, encourages more walkable neighborhoods and
prevents outdated rules from limiting new housing.
• Clarifying Development Study Requirements:
HB 5531 (Rep. Cynthia Neeley):
• Setback Requirements: HB 5583
This bill creates a clear timeline and fair standards for local
governments to review development proposals and make
timely decisions. Once all requested information is submitted,
municipalities have 75 days to review the final materials and
issue an approval or denial. Plans that have 100 units or more
have 30 additional days.
(Rep. Matt Longjohn):
Defines setback requirements in metropolitan statistical areas
at 15 feet from the front property line and five feet from the
sides and rear. This helps use land more efficiently, while
still allowing exceptions for sensitive areas like marshes or
waterways.
• Protest Petition Process: HB 5532
(Rep. Joseph Aragona):
• Duplex Expansion: HB 5584
(Sen. Jeff Irwin; Rep. Joey Andrews):
Clarifies and modernizes the local protest petition process to
better reflect community sentiment and provide consistency
for local decision-makers. Expands the petition area to 300
feet while setting a clear 60% signature threshold, helping
ensure that petitions represent broad neighborhood input
before a supermajority vote is required by the local council.
Permits duplexes in single-family residential zones within or
adjacent to metropolitan statistical areas, while providing a
clear statewide definition of a duplex.
• Accessory Dwelling Units (ADUs): HB 5585
(Rep. Luke Meerman): Defines ADUs and allows them on
parcels with single-family homes. Caps setbacks at five feet,
prohibits additional parking mandates and allows ADUs to be
built on- or off-site. This expands options for seniors, students
and families.
• Reasonable Dwelling Size: HB 5581
(Sen. Jonathan Lindsey; Rep. Tom Kunse):
Caps minimum dwelling size requirements at 600 square
feet in metropolitan statistical areas statewide.This makes it
easier to build smaller, more affordable starter homes and
apartments where large land parcels may not
be abundant.
All Zoning-Related Bills in the Package Includes Language that Clarifies:
1) Development plans must still comply with existing local, federal, and state laws related to environmental
protections, public health, water, sewer, stormwater, transportation, and other infrastructure requirements.
2) These proposed bills do not interfere with existing zoning reform law.
