• Accessory Dwelling Units by Portland & Seattle Home Builder Hammer & Hand

Small homes, big benefits

Changes in both Portland and Seattle building code have made Accessory Dwelling Units (ADUs) more attractive than ever. Done right, this housing type reaps major rewards for homeowners, from rental income to aging-in-place independence.

ADUs are self-contained, compact homes built on the same lot as an existing single-family home. They can be garage conversions, attic or basement living spaces, attached additions, or new detached units. Sometimes called “in-law apartments”, “granny flats”, or “backyard cottages,” these small-footprint infill projects support sustainable, walkable, accessible neighborhoods.

Hammer & Hand has the urban remodeling experience, attention to detail, and design connections to build the best ADUs in the region. Learn more about how much it costs to build an Accessory Dwelling Unit.
