Is an Accessory Dwelling Unit (ADU) Right for You?

Is an Accessory Dwelling Unit Right for You?

Are you having a hard time finding the right home in your budget? Or maybe you already own a home but could use some extra income or a designated space for aging loved ones. Either way, accessory dwelling units (ADUs) could be the smart solution you’ve been looking for in today’s market.

What Is an ADU?

According to Fannie Mae, an ADU is a small, separate living space that’s on the same lot as a single-family home. It must include its own areas for living, sleeping, cooking, and bathrooms independent of the main house. And they can take shape in a few different ways. Fannie Mae adds, an ADU can be:

The Benefits of ADUs

ADUs are growing in popularity as more people discover why they’re so practical. In fact, a recent survey shows that 24% of agents say an ADU, such as a mother-in-law house, is one of the most desired features buyers are looking for right now.

The Benefits of ADUs

The growing appeal makes sense. With rising costs all around you, an ADU can help supplement your income and ease some of the strain on your wallet. Whether you buy a home that has one already or you add one on, it gives you the option to rent out that portion of your home to help pay your mortgage.

Here are some of the other top benefits of ADUs, according to Freddie Mac and the AARP:

It’s worth noting that since an ADU exists on a single-family lot as a secondary dwelling, it typically can’t be sold separately from the primary residence. And while that’s changing in some states, regulations vary by location. So, connect with a local real estate expert for the most up-to-date guidance.

Bottom line

In today’s market, buying a home with an ADU or adding one to your current house could be worth considering. Just be sure to talk with a real estate agent who can explain local codes and regulations for this type of housing and what’s available in your area.

Methodology

TownRatings™ is a proprietary model developed by Team Coyle to provide homebuyers and sellers with a relative rating (assessment) of a town’s key characteristics, benchmarked against other Greater Boston towns. Ratings are based on publicly available data and Team Coyle’s on-the-ground expertise and are intended as a general guide only. Please consult a licensed real estate professional before making any real estate decisions. Ratings are current as of October 4, 2025.

RATING CATEGORIES

  • Quality of Schools: Based on Massachusetts Department of Elementary and Secondary Education (DESE) 2024 data, emphasizing Grade 10 MCAS English Language Arts and Mathematics proficiency rates and 4-year high school graduation rates. Together, these measures provide a snapshot of academic achievement and long-term outcomes.
    Scale: Above Average · Average · Below Average
  • Commute to Boston: Assesses commuting ease using travel time, distance, and in-town transit access. For towns with MBTA rail or subway service, commute times are measured to the line’s natural Boston endpoint (e.g., North Station, South Station, or Back Bay). For towns without in-town service, commute times are measured by car to Back Bay as the default reference point.
    Scale: Easy · Moderate · Challenging
  • Shopping & Dining: Reflects the density and variety of retail and restaurant options within a town or in adjacent hubs.
    Scale: Excellent · Good · Limited
  • Lifestyle: A general description a town's overall character (e.g., Upscale, Rural, Historic, Suburban, Urban/Vibrant).
  • Est. Annual Tax per $1M: The town’s residential property tax rate applied to $1,000,000 of value (as of the report date) for easy comparison.

HOW RATINGS ARE DERIVED

Ratings are determined using a blend of publicly reported data (e.g., DESE reports, MBTA schedules, municipal tax rates, business directories), mapping and transportation tools, and qualitative insights from Team Coyle agents active in these markets.
