An accessory dwelling unit is a complete home in miniature, with its own kitchen, bath, and entrance, built on a lot that already has a house on it. EJS Remodeling handles accessory dwelling units for homeowners throughout South Shore, covering design, foundation, structure, and the systems that make the unit fully independent. Josh Steinman owns the company and has led this work across the region for more than 20 years.

Why Homeowners Build an ADU

An ADU solves a specific set of problems that adding a room or finishing a basement cannot. It creates genuinely independent living space on a lot the homeowner already owns.

Aging Parents or Adult Children Need Housing

An ADU keeps family close without putting everyone under the same roof. It preserves privacy on both sides in a way that a spare bedroom never does, and it keeps the option open to repurpose the space later.

Rental Income From Existing Property

A separate unit lets homeowners generate income from underused yard or garage space without buying additional land. The income potential remains even when family circumstances change.

Flexibility as Needs Change

A unit that houses a relative this decade can become a rental, a dedicated home office, or guest space the next. Building it well from the start means it adapts without additional construction.

Planning an ADU in South Shore, MA

An accessory dwelling unit is a full residence, and the planning reflects that from the beginning. Getting the zoning and utility questions answered early determines what the project can realistically include.

Zoning Determines What Is Allowed

Size limits, setbacks, parking requirements, and owner-occupancy rules vary by town and shape the unit before design begins. Those answers have to come first, because a plan built without them often has to be rebuilt.

Utilities Have to Reach the Unit

Water, sewer or septic, and electrical service all need a clear path to the new structure. Septic capacity, in particular, can determine whether the project is feasible at all on a given lot, so it gets evaluated before any design work gets done.

Permits Cover Every System

Structure, foundation, plumbing, electrical, and HVAC each require permits and inspections at multiple stages. EJS Remodeling handles the filing and coordinates every required review so the project moves forward without delays caused by paperwork.

Accessory Dwelling Unit Services in South Shore, MA

EJS Remodeling handles accessory dwelling units from the first zoning conversation through the finished, occupiable unit, building detached, attached, and conversion ADUs across South Shore.

Design and Planning

We review unit type, size, placement, layout, and finish selections with you, completing all design and planning work in accordance with local zoning before construction begins so nothing gets redesigned mid-project.

ADU Types

We build detached ADUs, attached ADUs, garage conversions, above-garage units, basement ADUs, attic conversions, internal ADUs, in-law suites, pool houses, carriage houses, garden cottages, workforce housing units, and modular ADUs, each matched to the property and the intended use.

Foundation and Site Work

We grade the land and install the foundation, selecting from slab-on-grade, crawl space, full basement, frost-protected, concrete piers, or helical piers based on the soil conditions and requirements of the lot.

Siding and Roofing Materials

We install siding in vinyl, fiber cement, engineered wood, cedar shingles, cedar clapboard, composite, metal panel, and stucco. For roofing we install architectural asphalt shingles, metal roofing, cedar shake, composite slate, and standing seam metal, chosen to complement the primary home.

Structure and Exterior

We frame the unit with stick-built construction and engineered roof systems, then close it in with siding, roofing, and energy-efficient windows and exterior doors that protect the structure and tie its appearance to the existing home on the lot.

Systems and Interior Finishes

We install plumbing, electrical, HVAC, and indoor air quality systems to bring the unit to full residential function, then complete kitchen and bathroom installation, flooring, wall finishes, cabinetry, lighting, and interior trim to deliver a finished, livable space.

Why ADU Construction Benefits From a Professional Team

An ADU carries the full complexity of a house on a lot with constraints a new build on a fresh site never faces. Several issues specific to ADU projects have to be resolved before construction starts, not discovered partway through.

Zoning Decides the Project Before Design Does

Setbacks, height limits, and unit size rules can eliminate certain approaches entirely. Getting those answers first prevents a design from being completed, permitted, and then revised because it does not comply with rules that were knowable from the start.

Utilities and Septic Set Real Limits

Extending water, sewer, and electrical service to a second unit means working within what the property already supports. Septic capacity is often the deciding factor on smaller lots, and it shapes the entire scope of what the unit can include.

Every System a House Needs, the Unit Needs

Plumbing, electrical, HVAC, and the structure all have to meet residential code, not just be present. The work involved is closer to building a small home than adding a room, and it requires the same level of coordination between trades.

Why Homeowners Choose EJS Remodeling

Every ADU project at EJS Remodeling gets the same attention to detail and standard of workmanship the company brings to every other job in the South Shore.

Our ADU Construction Process

Every project follows a clear order of steps, starting with a property and zoning assessment and ending with a finished, inspected, occupiable unit.

1

In-Home Consultation

We walk the property, review placement, utilities, and access, and talk through unit type, size, and budget with you before any plan gets put together.
2

Detailed Estimate

You receive an estimate covering material selections, pricing, and a project timeline before anything gets scheduled. Nothing is left open-ended and nothing gets added without your approval.
3

Permits and Scheduling

We file the required permits, schedule inspections, and lock in a start date once approval comes through.

Frequently Asked Questions

What is an accessory dwelling unit and how is it used?

An ADU is a self-contained living space on a lot with an existing home, complete with its own kitchen, bathroom, and entrance. Homeowners use them for family members, rental income, guests, or as flexible space that changes purpose as circumstances change.

What types of ADUs can be built on a property?

Detached units, attached units, garage conversions, above-garage units, basement and attic conversions, internal ADUs, in-law suites, pool houses, carriage houses, garden cottages, workforce housing units, and modular ADUs all work depending on the property and local zoning rules.

What are the benefits of adding an ADU?

An ADU adds usable housing without additional land, creates a source of rental income, keeps family members close while preserving privacy on both sides, and gives the property a flexible space that adapts as needs change over time.

What should I consider when hiring ADU builders near me?

Look for familiarity with local zoning and permitting, a clear plan for utility and septic connections, experience with foundations and full residential systems, and the ability to match the exterior of the new unit to the existing home.
