CT HB05391

Establishes a housing density rating program administered by the State Responsible Growth Coordinator within the Office of Policy and Management to encourage municipalities to adopt zoning regulations that increase housing density

Creates four tier classifications for municipalities (Tier I through IV) based on housing density points awarded for adopting specific zoning policies such as reducing parking requirements, allowing accessory apartments, reducing minimum lot sizes, permitting duplexes and multifamily housing, and establishing transit-oriented districts

Requires municipalities to submit annual reports by July 1, 2025 documenting adopted zoning regulations eligible for housing density points, with the coordinator publishing municipal tier classifications by July 1, 2026

Imposes mandatory housing density requirements on Tier I municipalities starting October 1, 2026, including allowing multifamily housing as of right in areas with public sewerage or water systems and limiting parking spaces to one per studio/one-bedroom unit and two per two-plus bedroom unit

Provides incentives for higher-tier municipalities including doubled housing unit-equivalent points for Tier III municipalities, exemption from affordable housing appeals for Tier IV municipalities, and discretionary community development funding with grants of $1,000 per new resident for Tier IV municipalities
