ADU types in the recent set
Housing law — Connecticut
Connecticut's Public Act 21-29 (2021) makes accessory dwelling units permitted as-of-right in single-family zones, but let municipalities opt out by a two-thirds vote — and a majority of towns did, so whether an ADU is as-of-right depends heavily on the specific town.
Connecticut has no statewide 'missing middle' zoning law in force; a 2025 omnibus housing bill (HB 5002) with transit-oriented and middle-housing provisions was vetoed, leaving density to local zoning.
