CT HB05041

Requires landlords to provide home energy labels (DOE Home Energy Score, HERS Index, Energy Star, or Commissioner-approved alternatives) when listing rental units for rent, effective January 1, 2023.

Phased implementation based on municipality energy cost burden: July 1, 2023 for areas where households spend at least 10% of income on heating/electricity; July 1, 2024 for 6% threshold; July 1, 2025 for 4% threshold; July 1, 2026 for all municipalities.

Exempts dwelling units where rent includes fixed utility charges, buildings constructed after January 1, 2000, and landlord-occupied buildings (until July 1, 2026).

Authorizes municipalities meeting energy affordability criteria to establish civil penalties for violations: up to $500 for first violation and $1,000 for subsequent violations, with appeal rights to Superior Court.

Amends Connecticut housing law definitions to incorporate the new home energy labeling requirements into the state's rental housing statutes.
