Your Massachusetts ADU Specialists
Your property has untapped potential.
We help you unlock it.
Adding an Accessory Dwelling Unit to your property is one of the smartest moves a Massachusetts homeowner can make. Pathfinder handles every step, from zoning and design to permits and construction, so you don't have to figure it out alone.
Our Process
Three phases. One partner. Zero guesswork.
We manage your entire ADU project from first question to final inspection. You stay informed without getting buried in the details.
Feasibility Study
We analyze your zoning, assess your site, and deliver a clear picture of what's possible, including a preliminary budget, conceptual design, and financial overview.
Design, Engineering & Permitting
We manage your architect, engineers, and permitting from start to finish, attending zoning board meetings, handling municipal liaisons, and delivering approved permits so you can break ground with confidence.
Construction
We run scheduling, contractor selection, change order management, and quality control through final inspection and your certificate of occupancy. Your investment is protected at every stage.
Why Pathfinder
Built Different. For a Reason.
Pathfinder was founded by a Professional Engineer with years of experience managing complex, high-stakes projects. We bring that discipline to your ADU.
Feasibility First
We start with a detailed Feasibility Study to figure out if your project is possible, and what problems might arise. We begin solving these problems before you spend a dollar on construction.
Licensed Professional Civil Engineer
Most ADU builders don’t hold a PE. Ours does. Our technical depth means we catch problems before they become expensive, and we speak the language of every professional on your project.
Deep Local Knowledge
We know zoning inside and out; which towns move fast, which ones push back, and how to navigate each municipality's permitting process efficiently.
Full Transparency. No Surprises.
No scope creep you didn't approve. You'll know exactly what you're paying at every phase before you commit to the next one.
Get Started
