Exploring the Versatility and Value of Accessory Dwelling Units (ADUs)
With home prices in Massachusetts remaining at an all-time high, homeowners are exploring innovative ways to maximize their property's potential.
A growing trend is the addition of accessory dwelling units (ADUs), which are secondary residential structures on the same lot as the primary residence. ADUs can be integrated within the home, attached to it, or built as separate structures on the property.
This post explores the diverse design possibilities for ADUs, which are increasingly being viewed in Massachusetts as another solution for addressing housing scarcity.
MA Easing ADU Regulations
An ADU provision in the now $5.2 Billion MA Housing Bond Bill—the proposal formally known as the Affordable Homes Act by the Healey-Driscoll Administration—was adopted by the House and most recently by the Senate. The bill would allow one ADU per property by right in single-family zoning districts statewide. Homeowners would have to apply for special municipal permits for any additional units.
Communities such as Newton, MA, also aim to make developing ADUs or Accessory Apartments easier. For example, a website called Newton ADU was recently launched to help citizens research whether their lots would allow for an accessory apartment. Across the state, communities could greatly benefit from informative resources such as Newton's ADU checker as awareness of accessory dwelling unit possibilities increases.
ADUs as Additional Living Space
ADUs can be a solution for homeowners looking to expand their living areas. Whether used as a home office or a guest house, they can cater to specific needs and add versatility to the property. ADUs can also generate rental income or offer a temporary accommodation option, increasing the overall property value while providing a financial revenue stream.
In urban areas grappling with housing shortages, ADUs can create more housing options to accommodate individuals, couples, or small families. These apartments can also provide an opportunity for intergenerational living, allowing homeowners to accommodate elderly family members while ensuring independence and convenient proximity for family members with special needs.

Design Considerations for ADUs
Accessory Dwelling Units can provide additional residential structures on the same lot as a primary residence. These secondary dwellings can be internal within the original structure, such as a basement conversion, attached to the original structure, such as a garage conversion or a new addition, or detached from the main home as a free-standing unit.
Whether developing an internal ADU conversion, an addition to a home, or a separate unit on a property, creativity is key when designing within limited square footage. Open-concept layouts, built-in storage solutions, and transformable furniture are pivotal in leveraging space efficiently. Consistent architectural styles, materials, and landscaping also create a cohesive look.
ADUs also provide an opportunity to implement sustainable measures. For example, a unit can reduce its ecological footprint through eco-friendly material selections, energy-efficient appliances, renewable energy sources, and water-saving fixtures.
Work is underway on a new ADU project in Newton, MA, which will convert an existing garage into an apartment. Pictured above is the original garage and a rendering of the new ADU.

Our approach is to seamlessly blend the ADU's aesthetic with the primary residence and its surroundings. Complementary architectural styles, materials, and landscaping choices create a cohesive visual appeal. Pictured above are additional renderings from our garage conversion project.
While the potential of adding an ADU to a property is worth exploring, careful consideration must be given to building and zoning restrictions, privacy options, the time and cost for maintenance and upkeep, and the impact on a home's resale price.
Working with our clients on ADUs has been an exciting exploration in finding design solutions for independent units that add value and versatility to a residence.
