Accessory Dwelling Unit

What is an ADU?

An ADU, (Accessory Dwelling Unit) is a secondary residential living space located on the same lot of a single-family home. In the past, most homeowners would need to get a special permit or approval from the local zoning board in order to build an ADU.

The Affordable Homes Act now allows ADUs to be built without such approval. This new law aims to increase housing options and encourage the development of these smaller, secondary residences.

Imagine… Design. Build.

With recent changes to Massachusetts law, building an Accessory Dwelling Unit (ADU) in Beverly has never been easier. Whether you’re dreaming of an in-law apartment, a cozy attic conversion, or a standalone cottage, Godfrey Design-Build is here to make it happen.

Our team will guide you through the entire process, from initial design through final construction and beyond, ensuring your vision becomes a reality. Now is the ideal time to expand your home—let us help create the perfect space for your needs.

An ADU is a great opportunity to add living space and value to your property. An ADU can:

Create affordable housing options for adult children and relatives, allowing them to stay in their community or provide long-term solutions for seniors, whether by enabling caregivers to live nearby or allowing seniors to downsize while staying in their neighborhood
Provide an additional source of rental income to help cover costs including maintenance and repair expenses

"We worked with Pat, Fred and the Godfrey team to update our new house before we moved in and had the absolute best experience we could’ve imagined. Pat and Fred were professional and responsive – even making time to support a next-day walkthrough to help us with negotiations before we even closed on the house – and all projects were completed on time and within the communicated budget…"

What are the regulations around ADUs?

There are still some restrictions when it comes to building an ADU.

All ADUs must have a separate entrance, either directly from the outside or through a shared entry hall or corridor within the main dwelling. They typically include a kitchen, bath, and usually at least one bedroom.

And of course, all ADUs must comply with state building code requirements including safe egress. Additionally, there may be local regulations to comply with, including restrictions on short-term rentals. However, the new law no longer requires owner occupancy for the ADU or the principal dwelling. At maximum, only one parking space is required, and only for properties located more than a half mile from public transit.

In regard to size, ADUs must be no larger than half of the size of the main dwelling, or less than 900ft2, whichever is smaller. Local regulations may also have additional limitations regarding things like setbacks and height restrictions.

What are the

Different Types of ADUs?

Detached ADU

A standalone structure on the same lot as the primary home. These can be built in a variety of styles, from small cottages to larger guest houses, providing privacy and independence. Think pool house, tiny house etc.

Above-Garage ADU
Built above an existing garage, this type maximizes space on the property while maintaining a separate living area. It’s a popular choice for homeowners looking to make efficient use of their lot or to avoid restrictions like setbacks. This is considered an Attached ADU. Think granny flat, au pair suite, in-law apartment.

Attached ADU
This unit is physically connected to the primary residence. It shares at least one wall with the main house.
