Have you been thinking about adding an Accessory Dwelling Unit (ADU) to your property? For many homeowners, the idea comes up when they need additional space for aging parents, adult children, or want to create a source of rental income.
In Connecticut, a proposed update to state zoning law, a substitute version of H.B. No. 5507, could change how ADUs are regulated if it moves forward.
According to the Connecticut General Assembly’s bill analysis, the proposal would update statutory language from “accessory apartments” to “accessory dwelling units,” apply more uniform statewide standards for ADUs, limit certain local zoning restrictions, and establish a program for preapproved ADU designs.

Right now, ADUs are permitted in many Connecticut towns, but the rules vary significantly from one municipality to another. Some towns allow them with a relatively straightforward approval process, while others impose stricter zoning requirements or additional review steps that can make projects more difficult to move forward.
If enacted, the intent of the bill is to create more consistency statewide. Municipalities would be required to allow ADUs on residential lots, including those that previously opted out. The legislation would also limit certain zoning restrictions that can act as barriers to development, such as strict occupancy requirements, parking mandates, and other procedural hurdles that vary by town.
Detached ADUs would be more clearly recognized as well, including backyard cottages and garage conversions, which in many cases are currently subject to more restrictive local interpretation.
For homeowners, the broader takeaway is that ADUs are becoming a more central part of Connecticut’s housing conversation, and the regulatory landscape is likely to continue evolving.
