ADU Builder in Fairhaven, MA

Custom Accessory Dwelling Unit Construction in Fairhaven

Adding an accessory dwelling unit to your Fairhaven property can be a smart way to create additional living space without leaving the home and neighborhood you love. Whether you’re looking to accommodate family, create a private guest space, add a home office, or build a flexible living area for the future, American Pride Construction designs and builds custom ADUs around your property and your needs. From detached backyard cottages and in-law suites to attached ADUs and garage conversions, we handle the construction process from planning and permitting through completion.

Custom ADUs Built Around Your Needs

Every property presents different opportunities and challenges. Our team takes a personalized approach to ADU construction, creating spaces that complement your existing home while providing the functionality and privacy you need.

An ADU can provide your property with greater flexibility while helping you adapt to changing family and lifestyle needs. Instead of moving when your space requirements change, an ADU can allow you to create additional living space right on your existing property.

Common types of Accessory Dwelling Units we Build

Detached ADU (DADU)

A fully separate structure built in your backyard or side yard. Maximum privacy for both occupants, highest potential rental income, and the most flexibility in design. Ideal for larger lots with yard space to spare.

Attached ADU / Addition

Built as an addition to your existing home — sharing a wall but with a completely separate entrance and living space. Often less expensive than a detached unit and a great solution for smaller lots or tighter budgets.

Garage Conversion ADU

Transform an attached or detached garage into a livable, code-compliant dwelling unit. One of the most cost-effective paths to an ADU — the structure is already there, we bring the finishes, systems, and function.

Above-Garage ADU

Build living space above an existing or new garage — a carriage house style that is architecturally striking and highly efficient. American Pride has direct experience with this construction.

Interior / Basement ADU

Convert an underutilized basement, attic, or large interior space into a legal ADU with a separate entrance. Often the least disruptive build process and excellent for homes with deep basements or finished walk-out lower levels.

Waterfront ADU's

Southeastern Massachusetts' coastal properties command premium rental rates. We have deep experience navigating the additional permitting considerations for waterfront and near-coastal lots in towns.
