The Benefits and Types of Accessory Dwelling Units (ADUs)

Accessory Dwelling Units (ADUs) are becoming increasingly popular in Boston as a creative and practical solution to housing challenges. These small, secondary homes—like in-law suites, basement apartments, or backyard cottages—offer numerous benefits for both homeowners and the community.

Expanding Housing Options

ADUs provide an affordable way to increase housing availability in existing neighborhoods without disrupting their character. They help address the shortage of affordable homes and allow families to live together across generations, meeting evolving housing needs in a flexible and practical way.

Types of ADUs

There are several types of ADUs to consider, each with its own advantages:

1. Detached ADUs

   • Stand-alone structures, such as backyard cottages or tiny homes.
   • Perfect for offering privacy to tenants or family members.

2. Attached ADUs

   • Built as an addition to the main house, like an extended wing or a new section.
   • Offer easy access while maintaining some level of independence.

3. Interior ADUs

   • Created within the existing home by converting spaces like basements, attics, or spare rooms.
   • Cost-effective and makes use of otherwise unused areas.

4. Garage Conversions

   • A specific type of interior ADU that transforms a garage into a living space.
   • Ideal for repurposing underutilized parts of the home.

Generating Extra Income

ADUs can also provide homeowners with a steady stream of rental income, which can be used to:

• Offset mortgage payments, making homeownership more affordable.
• Fund home improvements or other large expenses.
• Build savings or supplement retirement income.

In Boston’s competitive housing market, ADUs not only help meet local housing demands but also provide homeowners with a reliable way to boost their financial stability while offering affordable rental options.

Strengthening Communities

ADUs are a smart way to create new housing without requiring major infrastructure changes. They allow long-time residents to stay in their neighborhoods by providing flexible spaces that balance independence with support. ADUs also help maintain strong community ties by offering affordable options for families, seniors, and individuals.

Key Benefits of ADUs

For the Community:

• Adds housing without large-scale construction.
• Increases affordable housing options.
• Encourages multi-generational and diverse living arrangements.

For Homeowners:

• Adapts to changing family needs.
• Provides housing or care for loved ones.
• Generates additional income through rentals.

ADUs are more than just extra living spaces—they’re an investment in Boston’s housing future. Whether you’re a homeowner considering adding an ADU or an advocate for better housing solutions, these small units can make a big impact.
