ADUs
ADUs (Accessory Dwelling Units) offer a flexible way to add living space without dramatically changing the footprint of a property. Whether attached, detached, or integrated into an existing structure, ADUs can support extended family, guests, rental income, or changing needs over time.
Our ADU projects focus on thoughtful planning, efficient use of space, and careful coordination—helping clients understand what’s possible and design a small home that feels intentional, comfortable, and well considered.
WHEN AN ADU MAKES SENSE
An ADU may be the right solution if:
-
You want to create space for family members or guests
-
You’re exploring rental or income-generating opportunities
-
You need flexible living space without moving or expanding the main home
-
Your property has zoning or site conditions that support an additional unit
Because ADUs are shaped by local regulations and site constraints, early planning is especially important.
OUR APPROACH TO ADU PROJECTS
ADUs require a balance of creativity, efficiency, and compliance. During the design process, we focus on:
-
Zoning and permitting requirements
-
Site placement and access
-
Layout efficiency and livability
-
Utility connections and infrastructure
-
Materials and systems scaled for long-term use
Design and construction decisions are developed together, allowing feasibility, cost, and buildability to stay aligned as the project takes shape.
WHAT TO EXPECT
Every ADU project is different, but most include:
-
Site evaluation and zoning review
-
Concept layouts and space planning
-
Scope definition and budget development
-
Coordination with engineers, utilities, and permitting authorities
-
A clear plan for construction logistics and sequencing
Throughout the process, we help clients navigate complexity and understand tradeoffs before
commitments are made.
COMMON QUESTIONS ABOUT ADUs
Are ADUs allowed where I live?
Yes. In Massachusetts, ADUs are allowed by right in single-family zoning districts under current state law. In Rhode Island, ADUs are also widely permitted, though the specific pathway can vary by property and municipality. Local zoning, setbacks, and Title 5 requirements still apply, and we help you review these early so there’s a clear picture of what’s possible.
How big can an ADU be?
In Massachusetts, ADUs are limited to 900 square feet or 50% of the primary home’s size, whichever is smaller. In Rhode Island, allowable size varies but generally falls within a similar range. We help confirm what’s realistic for your property early in the process.
Can an ADU be rented?
Yes. ADUs are intended for long-term living, whether for family members, guests, or rental use. Short-term rentals (such as Airbnb or VRBO) are not permitted under current ADU regulations.
Do I have to live on the property?
Owner-occupancy requirements vary by state and circumstance, but in many cases they are not required. We help clarify how the rules apply to your specific situation so there are no surprises.
Will I need to add parking?
Parking requirements are limited under current regulations. In many cases, little or no additional parking is required—especially for properties near public transportation. This is reviewed as part of early planning.
Do ADUs add value?
Yes. A well-designed ADU can add long-term value by increasing flexibility, supporting rental income, and making a property more adaptable over time.
