Room for Family, Right on Your Property

Rhode Island requires every town to allow one ADU per lot by right when it’s built inside the existing footprint of your house or an existing garage or accessory building, when your lot is 20,000 sq ft or more with a home on it, or on an owner-occupied property as an accommodation for a family member with a disability. Other projects can often still be approved through your town. We check your lot before anything is designed.

Yes, as a long-term rental. Since 2024, Rhode Island law bars towns from limiting ADU tenants by family relationship or age. Short-term and Airbnb-style rentals are not allowed anywhere in the state.

Yes. An ADU needs building, electrical, and plumbing permits, and often zoning approval. We handle all of it. Towns can’t charge more in fees for an ADU than they would for a new single-family home.

Not always. State law bars towns from requiring separate water or sewer lines in most cases, so many ADUs share the main house’s service. Detached units may still need new runs from the house. Separate metering is optional but useful for rentals.

Towns can set a maximum size, but they have to allow at least 900 sq ft for a studio or one-bedroom and 1,200 sq ft for a two-bedroom, or 60% of the main house’s floor area if that’s smaller. Towns also can’t stop an ADU from having up to two bedrooms.

Yes. We can design single-level layouts with wider doorways, curbless showers, grab-bar blocking, and step-free entries.

Converting space you already have, like a basement or garage, usually costs the least because the shell is already built. For new construction, an attached in-law suite is usually more cost-effective than a detached unit because it shares a wall and utilities with the house.

Yes. Once an ADU is legally established, a town can’t revoke its permitted status or make you remove it when the property changes hands or new people move in.

Private rules that conflict with Rhode Island’s ADU law are void. If your association already allows ADUs, its rules stand.

Towns can’t require more than one off-street parking space per ADU bedroom.

Yes. Towns have to allow ADUs as part of new homes and subdivisions, not only on lots that already have a house.

You start with a 5% deposit. The rest is split into progress payments that are paid before each stage of work begins, all laid out in a detailed contract with material budgets.

We do. One local team designs, permits, and builds your ADU with our own crew, so you have one point of contact from the first visit to move-in day.
