Accessory Dwelling Units
(ADU's)

What Is an ADU?

An Accessory Dwelling Unit (ADU) is a smaller, independent living space built on the same property as a main house. It includes everything someone needs to live comfortably, such as a kitchen, bathroom, bedroom, and entrance. ADUs come in many forms. Some are attached to the main house, like a finished basement or over-garage suite. Others are separate, standalone buildings in the backyard.

In Massachusetts, homeowners are using ADUs to add flexibility to their properties. These units offer more than just extra space, they can be rented out, used as guest quarters, or provide housing for family members. Because they’re smaller than a typical home, they often cost less to build and maintain. This makes ADUs one of the most practical investments for homeowners today.

Recent state laws have made it easier to add ADUs without going through a lengthy zoning process. Whether you want extra income or a place for loved ones to stay nearby, an ADU might be the right move. To explore what’s possible for your home, our home additions team can walk you through the process from start to finish.

Why Accessory Dwelling Units Are Booming in Massachusetts

ADUs are growing in popularity across Massachusetts due to recent legal changes and growing housing needs. New state laws now allow many homeowners to build ADUs without applying for special permits or variances. This change has opened doors in towns like Winchester, Lexington, and Woburn, where zoning laws were once strict.

More importantly, ADUs create flexible, livable spaces. Homeowners often use them as guest houses, in-law suites, or private rentals. Many are choosing to rent them on Airbnb or long-term lease for added monthly income. Others keep them ready for family, especially aging parents or adult children—so everyone has their own space while staying close.

These units not only offer privacy but also boost property value. In fact, a home with a legal ADU can sell for more and attract more interest. Our team at Aureli Construction handles every part of the build—from zoning research to construction.

A Smart Way to Earn Income or Support Loved Ones

Many Massachusetts homeowners are discovering the financial and emotional benefits of ADUs. First, these units make it easier to earn passive income. You can rent them out to traveling professionals, graduate students, or vacationers. Whether short-term or long-term, that rent can help cover your mortgage, taxes, or savings goals.

Second, ADUs give families options. If a parent needs daily care, it’s comforting to have them close—but still in their own space. A child returning from college may appreciate privacy while figuring out their next steps. Some even use ADUs as spaces for caretakers or nurses who support someone with health needs.

Others build an ADU as a private office, studio, or workshop. Remote workers love having a quiet space steps away from the main house. Artists and hobbyists gain creative zones to focus without distractions.

Planning Your ADU the Right Way (and Making It Energy Efficient)

When planning your ADU, start with your goals. Will you rent it? Will a family member live there? Is privacy a top concern? These questions shape the layout and design. Our team begins each project with a detailed consultation, followed by a customized plan.

We also make energy efficiency a top priority. A small space can have a big environmental impact when it’s designed smartly. We recommend using LED lighting, energy-efficient windows, and low-flow plumbing fixtures. For heating and cooling, consider a ductless mini-split system, it’s cost-effective, quiet, and highly efficient.

Good insulation is another key factor. Properly sealed walls and roofs keep heating bills low during cold Massachusetts winters. Solar panels may also be an option, especially for detached ADUs. Over time, these upgrades save money and reduce your carbon footprint.

Adding high-efficiency appliances in your kitchen remodeling plans is another smart move. Compact units like combo washer-dryers and convection ovens help save energy and space.
