ADU Feasibility Quick-Check

A few questions to gauge whether you can add an ADU under RI's law.

Is your lot about 20,000 sq ft (roughly half an acre) or larger?

Do you live in the home as your primary residence?

Would you build it inside the existing home (attic, basement, garage)?

Quick read

Likely eligible by right

On a residential lot of roughly 20,000 square feet or more, Rhode Island's law generally allows one ADU by right, subject to size, setback, and local permitting rules. Owner-occupancy may be required depending on your town.
