Building an In-Law Suite in Andover
Andover’s colonials and capes include older houses close to the historic center and newer homes farther out, and each can host an in-law suite in a different way. A parent or an adult child can gain a private bedroom, a safe bathroom, and a living area, attached to the house or set inside existing space.
Typical in-law suite projects in Andover:
- Attached suites for colonials and capes
- Basement suites in newer homes farther out
- Suites inside older houses by the historic center
- Private entrances planned with the layout
- Separate heating and cooling for the suite

Key Choices for an Andover In-Law Suite
Houses close to the historic center or in Shawsheen Village can have older layouts that shape where a private entrance or a safe bathroom fits, while newer houses off I-93 or I-495 may offer more room on the lot. Either way, local zoning for accessory living spaces is checked before design begins.
What we check before design:
- An existing garage that could become a suite
- The basement and its egress options
- Electrical capacity for the suite
- HVAC the suite can run on its own
- Plumbing routes for the bathroom
Clear signs a suite may suit you:
- Looking after an older relative has become part of daily life
- The family would like to stay together and keep its privacy
- A relative prefers an accessible bathroom
- An adult child is moving back in
- You need a space that can adapt later
During the in-home visit, we ask about who will live in the suite and how much separation your family wants, since the entrance, bathroom, and systems all follow from those answers.
Our process
From Planning to Move-In in Andover
To start, the structure is built: a new foundation and framing for an attached or detached suite, or the conversion of a garage or basement. After that, plumbing, electrical, and HVAC for independent living go in and pass inspection. The bathroom, kitchenette, floors, and trim come last, ahead of the final walkthrough at your Andover home.

FAQ
In-Law Suite Additions in Andover: Common Questions
Families in Andover considering a suite for a relative tend to ask four things: what permits and zoning involve, whether the suite can be detached, whether a kitchen is possible, and how to begin. The answers are below, in plain words. Another question? Phone our team.
What permits does an in-law suite in Andover need?
A permit from the building department, and in a number of towns a zoning review too, because a suite may be treated as an accessory dwelling unit. Town rules can cover its size, parking, and design. Our team reviews them before design, prepares the applications, and schedules every inspection.
Does an in-law suite in Andover have to be attached?
No. An attached suite connects to the house with an inside door and its own entrance, while a detached one sits on its own as a small building on the lot if local zoning permits. Connecting to the existing systems is easier when the suite is attached, and separation gives more privacy. We check the local rules and your lot first.
Can a kitchen go into an in-law suite?
Often, yes. A kitchen or kitchenette calls for plumbing, electrical circuits for appliances, and ventilation. A kitchen is also often what makes a suite count as a separate dwelling unit under local rules, so we check what the town allows before the layout is final.
What is the first step for an in-law suite in Andover?
It starts with a no-cost in-home consultation: request one on this page or call (978) 917-9072. We review the house and lot at your Andover home, go over who the suite is for, and compare attached, detached, garage, and basement options before any design. There is no obligation.
