Expanding What’s Possible with an ADU in Greater Boston
Many homeowners in Greater Boston are looking for ways to create more flexible living space without leaving the neighborhood they love. Whether it’s accommodating family, creating privacy for guests, or planning for long-term needs, the challenge is finding space that truly works.
Accessory Dwelling Units offer a unique solution.
An ADU creates a fully independent living space on your property while staying connected to your home. At Lee Kimball, we approach ADU projects with a focus on thoughtful design and long-term livability. Whether detached, attached, or within the existing home, each space is designed to feel cohesive, functional, and well integrated.
Designed for Flexibility, Privacy, and Long-Term Living
One of the biggest advantages of an ADU is flexibility.
Homeowners in Greater Boston use accessory dwelling units for a range of needs, from private space for family to guest accommodations, home offices, or rental opportunities. These spaces allow for separation and privacy while still staying connected to the main home.
An ADU can also adapt over time. What starts as a guest suite or workspace can evolve into long-term living for family or additional income.
Our goal is to create ADUs in Greater Boston that feel complete, comfortable, and designed to support how you live now and in the future.

Our ADU Design-Build Process
Designing and building an ADU requires careful coordination, especially in Greater Boston where zoning, permitting, and property constraints all play a role. Our design-build process is structured to guide you through each phase with clarity and confidence.
Initial Consultation
We start with a conversation at your home to understand your goals, property conditions, and how you plan to use the ADU. This helps establish direction early and identify key considerations for your project.
Feasibility & Concept Planning
Next, we evaluate what is possible on your property based on zoning, layout, and existing structures. We develop initial concepts that explore placement, size, and overall approach.
Design Development
Once a direction is selected, we refine the design and guide you through key decisions, including layout, materials, and finishes. This ensures the ADU is fully planned before construction begins.
Project Scope & Investment Alignment
We finalize scope, pricing, and project details so expectations are clear. Aligning design and budget at this stage helps reduce changes later and keeps the project on track.
Pre-Construction Preparation
Before construction begins, we coordinate permits, scheduling, and materials. You’ll also be introduced to your construction team and gain access to a client portal for updates and communication.
Construction & Project Management
During construction, our team manages every aspect of the build with a focus on quality, organization, and consistent communication. We keep you informed as your ADU takes shape.
Completion & Final Walkthrough
As the project wraps up, we review every detail with you to ensure the space meets expectations. The result is a fully functional, thoughtfully designed ADU ready to be enjoyed.
Frequently Asked Questions About ADUs
What is an ADU and how is it used?
An accessory dwelling unit, or ADU, is a secondary living space located on the same property as a primary home. It can be attached, detached, or created within the existing structure. In Greater Boston, homeowners use ADUs for a variety of purposes, including guest accommodations, in-law living, private offices, or rental income. The flexibility of an ADU makes it a valuable addition that can evolve with your needs over time.
Are ADUs allowed in Greater Boston?
ADU regulations vary by municipality, but many communities in Greater Boston are becoming more supportive of accessory dwelling units. Zoning requirements, lot size, setbacks, and parking considerations all influence what is allowed on a specific property. Because these regulations can be complex, it is important to evaluate feasibility early in the planning process. Our team helps navigate local requirements to determine what is possible for your home.
How much does it cost to build an ADU in Greater Boston?
The cost of an ADU depends on factors such as size, design complexity, site conditions, and whether the structure is attached or detached. In Greater Boston, high-end ADU projects often start in the several hundred thousand dollar range and can increase based on scope and finishes. Elements like utilities, foundation work, and zoning requirements can also impact overall investment. A design-build approach helps align budget and design early to provide greater clarity before construction begins.
How long does it take to build an ADU?
The timeline for an ADU includes both design and construction phases. In Greater Boston, permitting and zoning approvals can add time depending on the municipality and project scope. Design, planning, and approvals often take several months before construction begins. Once underway, the construction timeline varies based on complexity, but early planning plays a key role in keeping the project on track.
