Primary HB 2506

Requires the office of childhood to design and develop placards that include a QR code containing a link to a child care facility's complaint investigations and inspection reports

Maddy summaryHB 2506 requires Missouri's Office of Childhood to create placards with QR codes linking to licensed child care facilities' complaint investigations and inspection reports. These placards must be posted prominently at facility entrances by January 1, 2027, and include clear differentiation between complaint investigations and routine inspections. Inspection reports and complaint investigations will remain accessible via the QR code for three years, after which facilities may request their removal. The bill directly affects all licensed child care facilities in Missouri by mandating public access to their inspection history through this standardized system.

Proposes a constitutional amendment changing how judges are selected to certain courts

Maddy summaryHJR 119 proposes a constitutional amendment to change how judges are selected in Missouri. It would require the governor to appoint judges from three nominees provided by a nonpartisan judicial commission for vacancies in the supreme court, court of appeals, and St. Louis city/Jackson County circuit courts. For other judicial circuits, voters would decide at elections whether to adopt this appointment method (instead of the current system) or maintain the existing process, with changes allowed only once every four years. The amendment must be approved by voters in 2026.

Primary HB 3332
In committee · Missouri House · Lead sponsor
Modifies provisions relating to employment benefits for first responders

Maddy summaryHB 3332 modifies Missouri's Public Safety Recruitment and Retention Act to provide tuition awards for eligible public safety personnel and their dependents. Public safety personnel with at least six years of service (police officers, firefighters, EMTs, paramedics, etc.) may receive up to 100% of resident tuition for degrees in specific fields like criminal justice or fire science, subject to meeting license, employment, and admission requirements. Legal dependents of personnel with ten or more years of service also qualify for tuition awards covering associate or bachelor's degrees. The program requires applicants to first seek other federal and state financial aid before applying for the tuition award, with eligibility lasting up to five years or 120 credit hours.

Primary HB 1800
Passed · Missouri House · Lead sponsor
Changes the percentage of the cap on the inflationary growth factor for the assessment growth of real or personal property occurring within a political subdivision, defines assessment value, and adds provisions related to the sales ratio studies performed by the State Tax Commission

Maddy summaryHB 1800 modifies Missouri's property tax system by changing the inflation-based cap on how much local governments (cities, counties, school districts) can increase property tax rates annually. It revises the calculation for the "inflationary growth factor," requiring political subdivisions to adjust tax rates to maintain the same revenue as the previous year when property values change, but within a new, lower cap on rate increases. This directly affects local governments that collect property taxes, as they must recalibrate levies to match revenue from the prior year while adhering to the updated inflation limit. The bill replaces the existing cap with a revised formula to prevent excessive annual tax rate hikes tied to property value changes.

Passed · Missouri House · Co-sponsor
Requires the general assembly to approve proposed administrative rules

Maddy summaryHB 2559 requires state agencies to obtain legislative approval before implementing new administrative rules that would cost over $250,000 annually for government, businesses, or individuals. Agencies must notify the Joint Committee on Administrative Rules and the full legislature, which must pass a concurrent resolution approving the rule before it takes effect. Rules not approved this way become invalid, with exceptions for federal compliance or funding requirements. This directly affects state agencies creating significant-cost rules and shifts authority to the legislature for final approval.

Primary HB 3342
In committee · Missouri House · Lead sponsor
Prohibits personal property tax levies passed prior to January 1, 1975, from applying to motor vehicles

Maddy summaryHB 3342 prevents older voter-approved property tax levies (passed before January 1, 1975) from being applied to motor vehicles. This directly affects vehicle owners in jurisdictions where such outdated tax rules might have previously applied. The bill amends the law to specifically exclude motor vehicles from these pre-1975 tax levies, ensuring they no longer apply to cars or trucks. It clarifies existing tax policy without changing current tax rates or creating new taxes. The bill is currently under review by the Special Committee on Property Tax Reform.

Maddy summaryHB 1803 requires Missouri's Air Conservation Commission to suspend all motor vehicle emissions inspections by January 1, 2028. This affects all Missouri vehicle owners currently required to undergo emissions testing under the state's existing program. The bill mandates the suspension of the program established under Missouri's Air Quality Attainment Act. The change takes effect automatically on the specified deadline without further legislative action.

Primary HB 516
Passed · Missouri House · Lead sponsor
Modifies criteria of hazardous waste investigations and increases the hazardous waste fund appropriations

Maddy summaryHB 516 creates a dedicated "Radioactive Waste Investigation Fund" within Missouri's state treasury to investigate potential radioactive contamination. It directs the Department of Natural Resources to use this fund - funded by annual transfers of up to $1 million from the hazardous waste fund - to conduct scientific investigations in areas where local governments request them, prioritizing sites near known radioactive contamination. The bill requires public reporting of preliminary findings for 90 days, final reports with test results, and soil/water sampling (with homeowner permission in residential areas) to assess if contamination exceeds EPA standards. Any unused funds revert to the hazardous waste fund at year-end.

Primary HB 639
In committee · Missouri House · Lead sponsor
Establishes parental leave for school employees

Maddy summaryHB 639 establishes paid parental leave for full-time school employees in Missouri (called "education personnel") who have worked at least one year. The bill requires school districts and the state to split costs equally (50/50) for approved leave following a birth or adoption, covering up to 12 weeks. It ensures parental leave doesn’t reduce accrued annual or sick leave, continues leave accrual during leave, and aligns with federal FMLA if applicable. The law applies only to public school employees and mandates state rules for implementation and reimbursement.

Primary HB 960
In committee · Missouri House · Lead sponsor
Requires the Air Conservation Commission to suspend by January 1, 2027, any motor vehicle emissions inspection program established under the Air Quality Attainment Act

Maddy summaryHB 960 requires the Air Conservation Commission to end all motor vehicle emissions inspection programs operating under the Air Quality Attainment Act (sections 643.300-643.355) by January 1, 2027. This directly affects vehicle owners in the state who currently need emissions inspections to register or renew their vehicles. The bill’s key provision is a mandated suspension of these inspections by the 2027 deadline, replacing the existing program with no new requirements outlined in the text. The law changes the policy by eliminating a specific regulatory requirement for vehicles.
