ADU rules in Rhode Island

Building an ADU by right in Rhode Island.

Rhode Island has expanded its statewide rules to make Accessory Dwelling Units far easier to build, allowing them by right on many owner-occupied single-family lots. Local dimensional and building requirements still apply in each Rhode Island municipality, and we handle that process for you.

Homeowners across Rhode Island — in Providence, Warwick, Pawtucket, Rumford, Newport and beyond — are using ADUs to house family, generate rental income, and add long-term value. We tailor each Rhode Island ADU to the lot, the existing home, and local building requirements.

Your options

ADU types we build in Rhode Island.

Detached ADU

A standalone backyard cottage — the most private and flexible option, ideal for rental income or multigenerational living.

Attached ADU

A new addition connected to your existing home, such as an in-law suite with its own entrance, kitchen, and bath.

Conversion ADU

Converting existing space — a garage, basement, or attic — into a fully independent dwelling unit.
