AMESBURY, MA, October 3, 2026: BLB Design / Build, a design-build remodeling firm based in Amesbury, is sharing what North Shore families should plan for before they add an in-law suite or accessory dwelling unit (ADU). Some families want aging parents close by. Others are making room for an adult child who is moving back home. Either way, the firm says these projects are more complex than a typical renovation, and the early planning decides how well the space works for years to come.

The firm coordinates several kinds of in-law projects. An attached in-law suite is built onto the main house with its own entrance, kitchenette, bathroom and sleeping area. It is designed to match the home's rooflines, siding and window proportions. A detached ADU, such as a guest cottage or carriage house, adds site work and separate utility runs. Basement and garage conversions reuse an existing structure, but they need careful attention to egress, moisture, insulation, and heating and cooling. A second-story suite can save yard space on a lot where a ground-level addition will not fit.

According to BLB Design / Build, four areas shape most in-law projects:

Utilities. An independent living space needs its own plan for heating and cooling, electrical and plumbing. Homes on septic systems need a capacity check before bedrooms or bathrooms are added.

Privacy and sound. Separate entrances, sound insulation between shared walls and careful placement of windows and doors help two households live well side by side.

Accessibility. Zero-threshold entries, wider doorways and blocking for future grab bars cost far less to build in now than to add later.

The property itself. Many of the homes the firm works on are older, with limited lot coverage, historic character worth keeping or septic systems that affect what is possible. The team reviews structural conditions, utility capacity, lot coverage and setbacks, and it works with the local building department early, before design begins.

"In-law suite and ADU projects are personal. They're about your family, your property, and your future," said Ben Becker, founder and owner of BLB Design / Build. "That's why we treat every project with the care and accountability we'd bring to our own homes."

Each in-law project at BLB Design / Build starts with a conversation about how the family actually lives. Who needs to be close? How much independence matters? How might the space need to change over time? From there, one team handles the site assessment, design and engineering, permitting and construction. The firm coordinates the architects, engineers and licensed trade partners under a single project plan, from the first conversation through the final walkthrough.
