ADU Design & Build is a licensed and bonded ADU contractor serving homeowners throughout the greater Portland area and the Willamette Valley. Specializing in accessory dwelling units, the company helps homeowners transform unused basements, garages, and backyard spaces into functional homes and income-producing rental properties.

Founded in 2017, ADU Design & Build offers a full-service approach that manages every stage of the ADU process — from feasibility studies and design through permitting, construction, and final inspection. Their focus on transparency, communication, and efficient project management helps homeowners navigate the complexities of ADU development with greater confidence.

Homeowners receive:

Real-time project schedule updates
Progress photos from the job site
