Maddy summaryMichigan House Bill 6303 amends the state's construction code act to prohibit local enforcing agencies from requiring air tightness testing for commercial buildings. The bill specifically prevents the director of the construction code from creating rules that mandate this type of test to verify the continuity of a building's envelope. It directly affects commercial property owners and builders by removing a potential regulatory requirement for verifying how well a structure seals against air leakage. This legislation is tied to House Bill 6304 and will not take effect unless that companion bill is also enacted into law.

Maddy summaryMichigan House Bill 6300 amends the state's Freedom of Information Act to explicitly extend public records transparency requirements to the state legislature and the governor's office. The bill establishes specific procedures for these bodies to designate FOIA coordinators, process record requests, and handle appeals or civil actions for denied disclosures. It also defines a comprehensive list of exemptions for legislative and executive records, such as constituent communications, internal investigations, and security information, while clarifying that these new transparency rules do not override constitutional privileges and immunities.
Maddy summaryMichigan House Bill 6284 updates the state's sentencing guidelines by amending Section 16m of the Code of Criminal Procedure to include specific firearm-related felonies. The bill creates a comprehensive list of offenses, ranging from selling firearms to minors and prohibited persons to discharging guns in vehicles or at dwellings, assigning each a specific classification level and maximum prison sentence. These classifications determine how judges calculate sentences for these crimes, with penalties varying based on the severity of the act and any resulting injuries or deaths.

Maddy summaryMichigan House Bill 6304 amends the Stille-DeRossett-Hale single state construction code act to update and clarify definitions used in the state's building regulations. The bill introduces new terms such as "air tightness testing," "building envelope," and "cost-effective" regarding energy efficiency standards, while refining existing definitions for concepts like "agricultural purposes," "mobile home," and "structure." These changes directly affect local governments, building officials, and property owners by establishing a more precise legal framework for enforcing construction codes. The bill is tied to HB 6303 and will not take effect unless that companion legislation is also enacted into law.
Maddy summaryMichigan House Bill 6285 removes state-level restrictions on the manufacture, sale, and possession of silencers, shotguns with barrels shorter than 18 inches, and rifles with barrels shorter than 16 inches.

It also repeals a separate section of the law that previously addressed short-barreled shotguns, ensuring consistency in the state's firearm statutes.
Maddy summaryThis bill amends Michigan's Freedom of Information Act to explicitly extend public records disclosure requirements to the state legislature and the governor's office, which were previously excluded from the definition of a "public body." It also updates key definitions within the law to include modern digital technologies, such as cloud storage and quantum computing systems, in the scope of what constitutes a "writing" or public record. The legislation takes effect on January 1 of the first odd-numbered year at least six months after enactment, provided that a companion bill, House Bill No. 6300, is also passed into law.
Maddy summaryHB 4202 amends Michigan's income tax code to update deductions for retirement benefits and education-related payments. It specifically adjusts the maximum deductible amount for retirement/pension benefits (currently $42,240 for singles/$84,480 for couples) to automatically increase annually based on the Consumer Price Index, and clarifies rules for deducting payments made to Michigan's education trust for tuition. The bill affects Michigan taxpayers who claim these deductions, particularly retirees and those using education trust programs. It does not create a new "fetus exemption" (a misstatement in the bill title), but refines existing tax code provisions for retirement income and education savings. The bill is currently in committee after its March 2025 introduction.
Maddy summaryMichigan House Bill 6224 repeals the Comprehensive Road Funding Tax Act, which was enacted as Public Act 23 of 2025.

This bill honors Officer Darrian Young by naming the highway portion after him, with no policy changes or funding impacts. It amends state law to add this memorial designation as a new section (6d) in the existing highway act. The bill passed unanimously in the Michigan House on May 20, 2025, with immediate effect.
Maddy summaryHB 4189 names a specific bridge on South Grand Avenue over I-96 in Fowlerville as the "LCpl Michael W. Hanks Memorial Bridge" to commemorate a fallen Marine. The bill requires the state transportation department and Livingston County road commission to install signs at both approaches of the bridge designating its new name. This is a purely commemorative measure with no policy changes or financial impact, directly affecting the bridge location and signage in Fowlerville. It amends Michigan's Memorial Highway Act to add this designation without altering transportation policies or funding.
