Primary HB 409
In committee · Maryland House of Delegates · Lead sponsor
Juvenile Court - Jurisdiction (Youth Charging Reform Act)

Maddy summaryHB 409, the Youth Charging Reform Act, expands juvenile court jurisdiction by removing automatic transfers to adult court for certain serious offenses committed by youth aged 16 and older. It directly affects Maryland youth aged 16+ accused of specific crimes like robbery, murder, carjacking, or firearm-related offenses - previously excluded from juvenile court. The bill repeals sections that barred juvenile court from handling these cases, meaning such offenses will now typically be processed in juvenile court unless a judge orders transfer. This change modifies jurisdiction rules in Maryland’s Courts, Criminal Procedure, and Education codes, shifting how these cases are handled without altering sentencing outcomes.

Public Safety - Law Enforcement Officers - Prohibition on Face Coverings

Maddy summaryHB 155 requires all Maryland law enforcement agencies to adopt policies prohibiting officers from wearing face coverings (like opaque masks or helmets) during routine duties, with specific exceptions. The Maryland Police Training and Standards Commission must create a model policy emphasizing transparency and excluding religious items, medical masks, or safety gear (such as helmets for motorcycle operations). Officers violating this rule face potential fines or loss of civil immunity, but exceptions cover religious garments, medical protection, and occupational safety needs. The law takes effect October 1, 2026.

Investor-Owned Electric, Gas, and Gas and Electric Companies - Utility Rate Changes (Public Service Company Transparency Act)

Maddy summaryHB 540, the "Public Service Company Transparency Act," requires investor-owned electric, gas, and combined gas/electric utilities in Maryland to increase transparency around potential rate changes. Specifically, it mandates that these companies notify customers via bill inserts or email before seeking rate adjustments, provide a detailed 10-year rate trend report showing visual graphs and cost breakdowns, and include a standardized statement on all customer bills explaining the Public Service Commission’s role. Utilities must also distribute annual rate reports to customers and post them online, while the Public Service Commission must publish an annual rate trend report using data from these filings. The bill applies only to investor-owned utilities (excluding municipal or cooperative providers) and takes effect October 1, 2026, with first reports due January 1, 2028.

State Procurement - Constitutional Violations - Prohibited

Maddy summaryHB 334 requires state procurement officers to mandate that all bidders and contractors certify they are not violating the U.S. or Maryland Constitution and will refrain from such actions during the contract period. This applies to every entity seeking state contracts, including affiliates and divisions of bidders. The bill adds specific certification requirements to Maryland’s procurement law (sections 13-212.2 and 13-230), making constitutional compliance a condition for bidding and contract execution. It takes effect October 1, 2026, with no defined scope for what constitutes a constitutional violation. The policy change directly affects all businesses competing for state procurement contracts.

Primary HB 517
In committee · Maryland House of Delegates · Lead sponsor
Emission Standards, Ambient Air Quality Standards, and Solid Waste Management - Local Authority

Maddy summaryHB 517 clarifies that counties and cities in Maryland can adopt stricter local emission standards or air quality rules than state or federal levels, provided their standards are equally or more stringent. It also confirms local governments retain authority to regulate solid waste management systems without being limited by certain state provisions. The bill requires the Department of the Environment to publish clear information about this local authority on its website by October 1, 2026. This law directly affects local governments seeking to implement more protective environmental regulations within their jurisdictions. It does not change existing state standards but removes ambiguity about local regulatory power.

Education - Collective Bargaining - Certificated Employees - Class Size

Maddy summaryHB 473 repeals the current ban preventing public school employers in Maryland from negotiating class size limits with teacher unions. It removes the prohibition in Section 6-406(c)(3) that previously barred discussions about "the maximum number of students assigned to a class" during collective bargaining. This change directly affects certificated school employees (like teachers) and their unions, as well as public school employers (county school systems). The bill enables these parties to negotiate class size as part of their collective bargaining agreements, alongside other terms like salaries and working conditions.

Child Support - Capacity of Minors to Initiate and Defend an Action

Maddy summaryHB 384 allows minors who are parents to directly file or respond to child support court cases without needing a legal guardian. It amends Maryland law to override the standard rule requiring minors to have a representative, granting minor parents the legal capacity to initiate or defend child support actions (both temporary and permanent). This change specifically affects minor parents seeking or defending child support for their children. The law takes effect October 1, 2026.

Health Care Facilities - Hospitals and Freestanding Birthing Centers - Perinatal Care Standards

Maddy summaryHB 1380 requires Maryland hospitals providing obstetrical services and freestanding birthing centers to meet minimum perinatal care standards as a condition of licensure. The bill mandates the Maryland Department of Health to adopt regulations establishing these standards, which must meet or exceed existing Maryland Perinatal System Standards. Hospitals and birthing centers must comply with these standards to maintain their operating licenses. The law amends specific sections of Maryland's Health Code (19-319 and 19-3B-03) to implement this requirement, effective October 1, 2025.

Public Safety - Immigration Enforcement (Maryland Values Act)

Maddy summaryHB 1222 (Maryland Values Act) requires Maryland correctional facilities to detain and transfer individuals who are not lawfully present in the U.S. and have been convicted of a violent crime to federal immigration authorities within 48 hours when requested. It prohibits law enforcement officers from detaining people or prolonging arrests based on immigration status during routine stops or investigations, and bans transferring individuals to federal immigration authorities except for the defined "covered individuals" (those with violent crime convictions and unlawful presence). The bill also terminates existing immigration enforcement agreements between Maryland entities and federal authorities by a specified deadline. This directly affects state/local correctional facilities, law enforcement officers, and individuals with certain immigration statuses and violent crime convictions.

Maryland Medical Assistance Program - Maternal Health Self-Measured Blood Pressure Monitoring

Maddy summaryHB 553 requires Maryland's Medicaid program (Maryland Medical Assistance Program) to cover self-measured blood pressure monitoring for eligible pregnant, postpartum, or chronically ill individuals starting January 1, 2026. It specifically covers Medicaid recipients with conditions like diabetes, heart disease, chronic kidney disease, or cardiometabolic disorders. The bill mandates coverage for validated home blood pressure monitors and reimburses healthcare providers for training, data interpretation, and remote monitoring support. Additionally, it requires the state to launch an education campaign and submit annual reports on usage, health outcomes, and cost savings related to the program.
