What We Build

ADU Services

One company, one crew, one point of contact. We handle every type of ADU project across all three counties.

New Construction ADU

A standalone unit built from the ground up on your property. We design, permit, and construct it to Vermont code, ready for occupancy.

Garage Conversion

Turn an attached or detached garage into a fully livable ADU. We assess the structure, handle zoning, and convert it start to finish.

Basement Conversion

Finished basements can become high-quality ADUs. We evaluate ceiling height, egress, moisture, and get it permitted and built correctly.

Addition ADU

Add a connected ADU to an existing structure. More square footage, separate entry, and a legal unit that adds real value to your property.

Zoning and Permitting

Every town in all three counties has different rules. We research what your property allows, prepare applications, and see them through to approval.

Full-Service Build Management

One point of contact from consultation through final walkthrough. No coordinating between contractors. We own the outcome.

How It Works

The Process

We walk every project through six clear stages. You always know where things stand.

01

Consultation

We talk through your goals, your property, and your budget. No sales pitch. Just a straight conversation about what is possible.

02

Zoning Review

We research your town's ADU rules, setbacks, lot coverage limits, and any deed restrictions before any plans are drawn.

03

Design and Plans

Working plans are developed around what your property can support and what your town will approve.

04

Permitting

We submit and manage the permit applications. We handle follow-up with the town. You will need to sign the application. We will take care of the rest.

05

Construction

Our core crew is on site from start to finish. For specialty work, we bring in a small group of trusted subcontractors we have partnered with many times before. You get consistent, familiar faces on your property, not strangers.

06

Final Walkthrough

We walk the completed unit with you, confirm everything is right, and make sure it is ready for occupancy before we call it done.

The Crew

Who We Are

A small, experienced team that handles ADU projects from the first zoning call through the final walkthrough. You deal with the same people the whole way through.

Matt Parisi & Eric Osborne

Partners, Vermont ADU

Matt and Eric grew up in Richmond, Vermont, which means they have been getting into trouble together for a very long time. Creek swimming, bridge jumping — the kind of upbringing that produces people who know how to figure things out.

Since 2020 they have been building together, with more than 30 homes completed in and around Chittenden County. They know the towns, the trades, and the people who get things done in this region.

Matt's passion for ADUs came from his own real estate portfolio. After building one himself, he saw how much a well-executed ADU could change a family's financial picture. Vermont's housing landscape is hard. Multi-generational living is increasingly how families are making it work. Matt and Eric believe ADUs are one of the most practical tools available — and Vermont ADU is how they are putting that to work for you.

Common Questions

FAQ

Straight answers to the questions we hear most.

ADU costs in Vermont typically range from $80,000 to $275,000 depending on project type, site conditions, and finish level. Garage and basement conversions generally cost less than new construction. We give you a detailed estimate after a free consultation, not a vague ballpark off the internet.
Yes. All ADU projects in Vermont require local zoning approval and a building permit. Requirements vary significantly by town. Vermont ADU manages the entire permitting process across all towns in Chittenden, Franklin, and Washington County. You do not need to figure that out yourself.
From initial consultation to move-in, most ADU projects in Vermont take 6 to 14 months. Permitting timelines vary by town and typically run 4 to 12 weeks. Construction itself runs 3 to 6 months depending on scope. We give you realistic timelines up front, not optimistic ones.
In most Vermont towns, yes. Rules around short-term and long-term rentals vary by municipality. Many towns in Chittenden, Franklin, and Washington County allow ADU rentals under specific conditions.
A new construction ADU is a standalone structure built from the ground up on your property. A conversion repurposes an existing space like a garage or basement into a livable unit. Conversions are often faster and less expensive, but the right choice depends on your property, your goals, and what your town's zoning allows.
