Waterbury is required to permit accessory dwelling units as of right under CT PA 21-29 (2021 zoning reform). The city's extensive multi-family housing stock means many properties already function with multiple dwelling units. New ADU construction or conversions require building permits and must meet habitable space standards. Waterbury's revitalization strategy includes encouraging appropriate residential density. Garage conversions and basement apartments are common conversion types. The building department reviews ADU plans for compliance with the CT State Building Code. Fire safety requirements including separate egress may apply.
Towns cannot deny conforming ADU applications under PA 21-29. Unpermitted ADU construction: standard code enforcement.
