Accessory Dwelling Units in Brewster, MA
Create Independent Living Space with Expert ADU Design & Construction
Expert ADU Design & Construction
Accessory Dwelling Units (ADUs)—also known as in-law apartments, granny flats, or backyard cottages—offer flexible solutions for multigenerational living, rental income, and aging in place. At Appropriate Home Design, we specialize in creating ADUs that provide true independence while maintaining connection to the main home. Our design-build approach ensures your ADU meets all local regulations, integrates seamlessly with your property, and provides comfortable, functional living space whether for family members, long-term tenants, or short-term rental income.
Massachusetts has been progressive in encouraging ADU development as a solution to housing shortages and affordability challenges. However, each Cape Cod town has its own specific regulations regarding ADU size, placement, parking, utilities, and use restrictions. Our four decades of experience navigating local zoning codes, building departments, and permitting processes means we understand exactly what's allowed in your town and how to design ADUs that meet all requirements while maximizing functionality and value. We handle every aspect—from initial feasibility assessment through design, permits, construction, and final inspections.
Whether you're planning an attached ADU addition to your home, converting existing space like a garage or barn, or building a detached cottage on your property, our team brings comprehensive expertise to your project. We understand the unique considerations of ADU construction: separate entrances and utilities, efficient use of limited square footage, soundproofing between units, ADA accessibility when needed, and design that complements the main house while providing true independent living. The result is additional living space that enhances your property value, provides flexibility for changing family needs, and potentially generates rental income.
Benefits of Building an ADU
Multigenerational Living
House aging parents or adult children with independence and privacy while maintaining close proximity and family connection.
Rental Income
Generate steady monthly income through long-term tenants or seasonal rentals—particularly valuable on Cape Cod's strong rental market.
Property Value
ADUs significantly increase property value and marketability by adding functional, independent living space.
Flexibility
Use changes over time—in-law suite today, rental tomorrow, home office next year, or guest quarters as needed.
Aging in Place
Allow family members to downsize from the main house while staying on the property, or provide accessible living for those with mobility needs.
Efficient Living
Smaller ADU spaces are more affordable to heat, cool, and maintain than traditional homes while providing complete independence.

ADU Planning Considerations
Zoning & Regulations
Each town has specific rules for ADU size, placement, parking, and use. We navigate these requirements to design compliant ADUs that maximize your property's potential.
Utilities & Systems
ADUs need water, sewer/septic, electrical, and heating/cooling. We design efficient systems whether extending from the main house or installing separate services.
Privacy & Soundproofing
Proper insulation, soundproofing, and layout design ensure privacy for both units—essential for harmonious multigenerational living or rental situations.
Accessibility
We can design ADUs to be fully ADA accessible with no-step entries, wider doorways, and accessible bathrooms—important for aging occupants.
Parking Requirements
Most towns require additional parking for ADUs. We incorporate parking solutions that meet codes without dominating your property.
Design Integration
ADUs should complement your main house architecturally. We match materials, styles, and details so the ADU enhances rather than detracts from your property.
