Accessory Dwelling Units (ADUs) in Portland

Planning an ADU for Your Home

We design and build accessory dwelling units (ADUs) that create fully functional living spaces on your property. An ADU is a secondary home that typically includes a kitchen, bathroom, and living area, designed for flexibility and long-term use.

ADUs are commonly used for rental income, guest housing, home offices, or multi-generational living. By adding an ADU, homeowners can increase property value, improve functionality, and make better use of available space while maintaining privacy.

ADU projects can be built as detached units, above garages, or integrated into your existing home, depending on your property and goals. With the right planning and construction approach, an ADU becomes a seamless extension of your home that’s both practical and well-designed.
