CT HB05288

Replaces the term "accessory apartment" with "accessory dwelling unit" throughout Connecticut statutes, effective October 1, 2026

Prohibits municipalities, special districts, sewer authorities, water authorities, and water companies from requiring installation of new or separate utility connections directly to accessory dwelling units or imposing related connection fees

Clarifies that accessory dwelling units shall not be considered a new residential use for calculating utility connection fees or capacity charges, unless constructed simultaneously with a new single-family dwelling

Excludes properties with only a principal dwelling and accessory dwelling unit on the same lot from the definition of "community sewerage system"

Updates affordable housing statutes to reflect the terminology change while maintaining existing affordability requirements (housing costs at 30% or less of income for households at 80% or less of median income for at least 10 years)
