SB 9 provides a tax credit for Connecticut businesses with 100 or more employees in federally designated "severe nonattainment" air quality areas (as defined by the Clean Air Act). The credit covers 50% of eligible spending on commuting programs that reduce single-occupancy vehicle trips, including public transportation, carpooling, or microtransit services, up to $250 per employee annually, with a total annual cap of $1.5 million. Businesses must submit a plan to the state transportation department detailing how they will implement these programs to qualify for the credit.

HB 5401 updates how Connecticut adopts and revises its State Building Code. It requires the State Building Inspector and Codes Committee to base the code on a nationally recognized model, limits revisions to once every six years (or per two model cycles), and mandates provisions for energy conservation and EV charging circuits in new residential garages. The bill also imposes a temporary pause on new building standards from October 2026 to October 2032, except for safety, federal funding, or accessibility needs, and prohibits local municipalities from enforcing stricter rules than the state code during this period. Additionally, it requires mandatory training for building code officials and professionals like architects and contractors on the State Building Code and Fire Safety Code.

This 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.

HB 5246 makes minor technical updates to Connecticut's energy and technology statutes. It adjusts deadlines for electric distribution companies to share regulatory evaluations with the Department of Energy and Environmental Protection, ensures certain financing orders and transition assessments cannot be altered, and mandates annual reports on energy efficiency metrics. These changes directly affect electric distribution companies, the Department of Energy and Environmental Protection, and the Office of Consumer Counsel. The bill updates legal language without altering substantive policy and takes effect upon passage.

HB 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.
