ADU Design and Build

ADU Design and Build is a licensed design-build firm serving the Portland, Oregon area and Willamette Valley that manages the complete ADU development process from site analysis through final construction, eliminating the need for homeowners to coordinate multiple contractors or navigate permitting independently. The company handles all phases—design, engineering, permitting, and construction—while specializing in detached backyard units, garage conversions, and interior space renovations tailored to rental income, multigenerational living, or property value enhancement. Their integrated approach addresses the full scope of ADU complexity, from feasibility studies and cost transparency to inspections and project closeout.
