Primary HB 5208
Signed into law · Connecticut House · Lead sponsor
AN ACT CONCERNING DATA SECURITY, PAYROLL PROCESSING, CONSUMER FRAUD PROTECTION, MORTGAGE LOANS AND EMPLOYEE CREDIT RATES.

Maddy summaryHB 5208 requires the Department of Banking to study financial transactions occurring within the state. The department must complete this study and submit a report to the General Assembly's Banking committee by January 15, 2027. This bill does not create new laws or directly affect specific groups; it only mandates a study to inform future legislative decisions. The report will be prepared in accordance with existing statutory procedures for such studies. This is a procedural measure focused solely on gathering information, with no immediate policy changes or implementation.

AN ACT CONCERNING ONLINE SAFETY.

Maddy summarySB 5 (AN ACT CONCERNING ONLINE SAFETY) requires subscription-based AI providers (e.g., companies offering AI tools via paid plans) to give consumers clear, written disclosures about subscription terms before signing or renewing. This includes detailing any usage limits, such as restrictions based on user behavior or changes to prior terms. The bill also establishes new safety rules for "frontier developers" of advanced AI systems ("foundation models"), defining "catastrophic risk" as scenarios where AI could cause mass harm (e.g., aiding weapon creation or severe physical injury) and mandating risk assessments by covered employees. It does not ban specific AI uses but sets transparency and safety protocols for high-risk systems. The law takes effect October 1, 2026.

Primary HB 5377
Signed into law · Connecticut House · Lead sponsor
AN ACT CONCERNING RETURN OF HEALTH CARE PROVIDER PAYMENTS.

Maddy summaryHB 5377 modifies health insurance billing rules to protect providers and improve transparency. It shortens the timeframe insurers can demand repayment for claims from 18 to 15 months after a clean claim is submitted (except for fraud, billing errors, duplicate payments, or federal program overlaps), requires insurers to provide 30 days' notice and an electronic appeal process for repayment demands, and mandates off-site hospital facilities to submit their unique national provider identifier (NPI) and tax ID on all claims. These changes directly affect health insurers, healthcare providers, and off-site hospital facilities, ensuring clearer billing requirements and reducing disputes over claim payments. The bill takes effect October 1, 2026, for the NPI requirement and January 1, 2027, for the repayment timeline changes.

Primary HB 5004
Signed into law · Connecticut House · Lead sponsor
AN ACT CONCERNING CHILD WELFARE ACCOUNTABILITY AND TRANSPARENCY.

Maddy summaryHB 5004 requires child welfare agencies to conduct background checks before placing a child with a relative or non-licensed caregiver in an emergency situation. Specifically, agencies must complete a federal criminal history search and check the child abuse registry within 10 days, followed by state/national criminal records checks; refusal to provide fingerprints triggers immediate child removal. The bill also mandates that courts prioritize placing children with relatives or "fictive kin" (close family friends) over other options when safety allows, and requires written documentation for all placement decisions. This directly affects child welfare agencies, relatives/fictive kin caregivers, and courts handling emergency child safety cases.

Primary HB 5406
Signed into law · Connecticut House · Lead sponsor
AN ACT CONCERNING ASSORTED MEASURES RECOGNIZING AND HONORING THE HEROISM OF VETERANS AND MEMBERS OF THE ARMED FORCES AND MAKING VARIOUS REVISIONS TO STATUTES RELATED TO VETERANS' AND MILITARY AFFAIRS.

Maddy summaryHB 5406 establishes a new ribbon and medal to honor Connecticut veterans and reserve members who served during wartime while residing in the state or being domiciled there at the time of the award. It creates eligibility for veterans called to active duty in wartime or reserve members serving during wartime, with awards potentially given posthumously to those who died after November 12, 1918. The Commissioner of Veterans Affairs and Adjutant General will administer the award process, including designing the ribbon/medal and distributing it using existing military funds. This bill amends Connecticut General Statute §27-73e to implement the honorific award, with no financial or benefit changes beyond the ceremonial recognition.

Primary HB 5313
Signed into law · Connecticut House · Lead sponsor
AN ACT CONCERNING THE DEVELOPMENT AND IMPLEMENTATION OF A PLAN FOR THE USE OF UNIFORM STATE-WIDE CASE IDENTIFICATION CODES IN DOMESTIC VIOLENCE CASES.

Maddy summaryHB 5313 requires the Chief Court Administrator to develop a plan by January 1, 2027, creating uniform state-wide case identification codes for domestic violence cases across three state systems: the Judicial Branch, Division of Criminal Justice, and Department of Emergency Services. The codes must consistently track all domestic violence cases (defined as family violence between household members under state law) in electronic case files, improving statewide data collection for reporting and policy analysis while maintaining confidentiality. This plan must be reported to legislative committees by February 1, 2027. The bill directly affects how state agencies track and manage domestic violence case data, aiming to standardize identification without changing legal definitions or services.

Primary HB 5525
Signed into law · Connecticut House · Lead sponsor
AN ACT CONCERNING A RAPID RESPONSE PROGRAM FOR CERTAIN AQUATIC INVASIVE SPECIES.

Maddy summaryThis bill establishes a rapid response program to quickly address new or spreading aquatic invasive plant species in Connecticut waterbodies, primarily affecting state agencies and property owners near affected lakes and ponds. It requires the Department of Energy and Environmental Protection to expedite permits for containment efforts, especially for hydrilla, and allows the Office of Aquatic Invasive Species to coordinate immediate treatment without requiring separate notices to waterfront property owners. The legislation creates an interagency task force to develop response protocols and a statewide management plan, while also mandating that public health officials review permits for treatments near drinking water sources.

Primary SB 321
Signed into law · Connecticut Senate · Lead sponsor
AN ACT CONCERNING REQUIREMENTS FOR CERTAIN EXCAVATION PROJECTS.

Maddy summarySB 321 modifies a state law to clarify that contractors or property owners obtaining permits for excavation work in public highways are not required to keep the excavation site open after work is completed - unless the specific permit explicitly states this requirement. The bill directly affects those performing highway excavations by removing a default obligation to maintain open sites, streamlining post-work procedures. Key provisions specify that permit conditions alone can dictate site maintenance, not the underlying law. This change aims to reduce unnecessary delays and costs for contractors without altering existing permit requirements. The law takes effect October 1, 2026.

Primary HB 5334
Signed into law · Connecticut House · Lead sponsor
AN ACT CONCERNING RIPARIAN AREAS.

Maddy summaryHB 5334 amends Connecticut's wetlands and watercourse protection laws by clarifying key terms and expanding protections. It defines "riparian area" as land bordering watercourses (delineated by the ordinary high-water mark) and specifies "natural vegetative cover" as native plants (excluding lawns and invasive species). The bill explicitly excludes "water-dependent uses" (like marinas, fishing facilities, and waterfront industries) from "regulated activity," meaning these operations won't require permits for direct water access. This change aims to balance environmental protection with economic activities that rely on water resources, directly affecting property owners, developers, and businesses near waterways.

Primary HB 5146
Signed into law · Connecticut House · Lead sponsor
AN ACT CONCERNING A STUDY OF THE REMEDIATION AND DEVELOPMENT OF BROWNFIELDS IN THIS STATE.

Maddy summaryHB 5146 requires Connecticut's Commissioner of Economic and Community Development to study challenges and opportunities related to cleaning up and redeveloping brownfields (underutilized properties with potential contamination). The commissioner must submit a report to the legislature's commerce committee by February 1, 2026, detailing findings on remediation and development issues. This bill does not create new regulations, allocate funding, or change current law - its sole purpose is to inform future policy decisions through a formal study.
